Found a muffler locally and have fitted it. Put a carb full of fuel down its little gob , flicked it and Gor Blimey it ran for 5 seconds at least. Hasn't turned in donkey's years! So IC it is. Just started covering it in Solartex. An ancient roll I've had for years too. Bought originally to cover the cockpit area on my model of Miss Britain III, so almost none missing from the roll. Had trouble with wrinkles, but then found I was using the iron too cool. Turned it up and last night it all went well.

I confess I am in 2 minds over this. Having an OS 10 is ideal, but then it doesn't have a muffler, so I'll have to make one, a bit of a faff. But then, I have fuel, somewhere a glow stik and I think my son even has my old starter for one of his boats. I love the smell and so does my wife so that's no problem. The lack of mess? Well it's only a wipe down with a rag when you're done.
Starting frustration and dead sticks...yes, that's certainly a consideration. Our club is still more IC than electric, so loads of help if needed with recalcitrant engines. I recently re-bearinged an HB 25 and they got that running well on a test stand. Really, it's only the muffler hassle that may yet put me off the OS installation. that and the fact that I've now glued up the firewall where the hole goes for the electric! Although that, of course, is for a big old 550, not a comparatively small brushless.
Of course, then there's the expense. I don't have a big brushless (well I do, but that's in an outboard motor speedboat), I'd need a new ESC and I don't have a suitable battery. Biggest I have is a 2200 3S. Ah, just re-read and seen that's the battery you mention for the Cub.

Martin

Hi Martin, thought you might have gone electric with the Cub. I recently made a repro of my 1975 48" Graupner PA18 Super Cub, and used a 28mm 1200kv brushless motor with a 3s 2200Mah LiPo. It has more power than you need by a country mile and is very quiet. Takes off with around 1/4 throttle. This TGY motor is one of the most powerful I have found for its' size, and I had one of the HK Cosmic Wind crappy 900mm glass models up to 91 mph with 2 x 2s 1800Mah 20c batteries strapped together (these motors take a 3s-4s)- 40c batts would have had it over the ton.
Problem was, being yellow (the worst colour I've found for visibility on a sunny day) and being so small and fast, I actually lost it for a few secs while going vertical at high speed (sort of blended into the sky)! You don't need a huge electric to pull a model, roughly need one which will handle the same sized prop as the model would normally use with an IC motor, and pull the same max revs. The beauty of electrics is the lack of mess, damaged fingers, starting frustration, expensive glow plugs and noise, plus your plane will last longer not having oil all over it constantly (and because it has no smell your missus might let you bring it in the house!)😂. Depending on your finished weight, a motor of this nature might be all you need ( or a lower power 35 Diam motor). Just a thought.

This is a 58.8" span kite, so I think the OS10 will be OK, but not over the top. I'll give it to someone else to fly to start with. The water fittings sound interesting, but I never ever got an engine to work in a boat. I have water fittings for my ED Racer, but would never bother trying to fit them or use them. They're just interesting history.

Steering wheels on soap boxes. Nah, too much weight. A pivoted beam steered by feet was all we needed.

Martin

Hi Martin - the OS10 will definitely be Super Cub rated - bags of power there - just don't overprop.
Interestingly enough I have a water cooled head for an OS - not sure if its for a 10 or 20 - looks like a 10. Also has what looks like a back plate with two water intake fittings and all the bolts etc. Both components obviously original parts . Never found either a motor or taker for it . Price was R9.52 in 1982 (now roughly 50p !!!)
Wot no steering wheel - we had those in solid wood - piece of pipe, cable ,two pulleys and a pair of eyebolts. Shows you us colonials were much more civilised - although the local soap box derby was run by the members of SOE (Sons of England society)

Doug, I've ordered some yellow as the Cub I flew was that admittedly predictable colour.

red, I had an uneventful take-off, but yes the landing was a bit wobbly, but that was probably due to my finding "push right, go right" completely counter-intuitive. I grew up, as did every lad, with soap boxes where you push right you go left.

I have an OS 10 for it. The company say they flew the prototype happily with one. I have beefed up the engine mounting former a bit to take the vibration.

Martin

Hi Martin - just remember to use the right size motor for scale flight . Having learned to fly in the full size one know they have a few odd characteristics - in a 30knot headwind for instance you had to use the throttle to land - don't throttle back all the way until some one ties the plane down ......... they don't like flying backwards unlike the Pitts. Being a tail dragger the rudder is ineffective until it comes up into the slipstream - hence a lot of wobbly takeoffs - having to fly from the back seat did not help forward vision either.
Of course you can always turn it into a "Super" Cub (the version with the much larger motor) which the fellows from National Parks learned to fly in and were often seen "Prop Hanging" on takeoff. The donor of the Cub must have been on tenterhooks watching..............

Looking good Martin👍
What colours will you cover it?
Cheers, Doug

Here's the frame:-
Spent today adding fairings to the fuselage and finishing the servos in the wings for the new ailerons.

M

Glad to hear that Martin😊
Also glad I didn't have to go any deeper into your TX 😉

Have fun with the Cub.
I'm sure that with your "Old Pro" skills you'll do an even better job of the covering.
Just don't have the iron too hot.
Do some tests on some off cuts first.
I did, and was glad of it !!
Cheers, Doug

BTW, your repair to my DX5e worked a treat as one chap at the club bound it to the Orange Rx. (again, just to show me) and another old master flyer gave the Pietenpol its maiden using the Tx and reported no problems as he flew the wee foamboard plane beautifully.
Thanks again for your great work.

Martin

Actually, Doug, it was just over a week, but I had a Matra pattern to make in that time too.
You made a sweet job of covering that wee bipe. I hope I can make the Cub look as good. I've ordered the roll of covering and my daughter has a spare iron she's bringing over. I'll spend the time sanding it all smooth.
Pics later today if this dull weather ever brightens!

Martin

Wow! 😮
Built already in two weeks!!
Pics pics pics please👍
Funny, I also thought ailerons were included.
Seems to be quite a lot of little control surface hinges in the kit.
Looking forward to pics and a maiden flight vid😊
I'm chuffed to learn that there's at least one thing I've done that you haven't. Yet!
Before I moved to Munich, end Sept 1985, I built the Simprop Zaunkönig (=Wren) and had to iron on the covering. Was much easier than I had expected.
Still got the .047 glow job I bought for it, Cox or maybe Enya? Might refit it with a brushless sometime.
Ciao, Doug

The Cub kit is built. Just need to cover it now, which is something I have never done before. Looks like I'll have to buy a travelling iron as we can't find the domestic one. Not something we have needed for a long time as we don't wear posh clobber any more! Had to add a sheet of 1/16th balsa as there wasn't enough to do the shear webs on the starboard wing, but I had some in the shed. Also have a nice wee OS 10 and an engine mount to put in it. I already have electric aircraft, so this is for IC. I've enjoyed the build of this one, Doug. OH, also converted the wings to take ailerons, which I'd assumed were in the kit. No sweat.
Martin

Hi Martin,
most of us played with the Keil Kraft & Veron kits in our youth. The small kits fitted the pocket money slot very well - most succumbed early - have memories of Jetex units climbing away from your new model on their own - never to be found. Others succumbed to the force of a penny Ronden "Flash Bomb" lit on launch - spectacular. Then there were the larger kits - rubber powered built with fathers assistance - home carved propellers - which flew out of sight - also never to be seen again. One climbed out on a thermal until a dot in the sky - turned up on a farm 20 miles away unscathed - always had name and address/phone no on a small card on the models.....Later the usual ED Bee's , Allan Mercury 1.5's etc . Watched a 40" span Piper of mine trying to take off with a friends clapped out Bee - ran the length of the rugby field and lifted just in time to intercept the posts............
Have 90% of the flying scale model plans - always mean to build one but designing and making commercial kids kits on the Laser intervenes. So far Land Rover series 1 , Defender, Suzuki SJ410 , Generic Jeep, Willys 1946 Jeep, Pitts Special , Tiger Moth and Eurocopter - all made with 3mm MDF - either fully designed or heavily modified by myself.

It's amazing how many people do other kinds of modelmaking but rarely say anything. I just started a Facebook page for a laugh called My Other Slot Car's an Aeroplane and it has already proved really popular!
One guy has a serious obsession with stick and tissue Keil Kraft kits! Nobody knew! Only one has admitted to modelboatitis though.


Martin

not sure what I have man read here, was it a cub for sale? any opportunity on my rare visits to the forum to blab about anything that I have an interest in! so here is my Beaver float plane, with custom Harbour Freight decals and paint job!I was experimenting with servo operated rudder floats, every fibre in my body was saying dont fly on salt water, but how could you resist that backdrop👍

Floats are quite tricky to take off and land with, easier with the likes of my avatar, a boat style hull, but more prone to bouncing which looks rubbish!

Now you tell me - thought floats were more prevalent from what my pal said. He used a Beaver mostly though, DH of course - not the dam builder with big teeth ..........

Ironically, not with skis, but floats. He sent me drawings of more makes of float than I could shake a stick at! It seems De Havilland were major float makers. Who knew?

Trouble is, we rarely get snow and if we do get a flurry, the wind blows it away and the track to the flying club would be closed.

Martin

OK looks like you win ...........

I know someone who lives there and makes kits of those kinds of aircraft, albeit little 1/72 nd scale ones. Beautifully vac-formed.

Martin

Hi Martin - not on a Cub - floats are more common. Actually know someone who was a bush pilot there.

Haha, skis in Alaska, methinks, or those huge Tundra wheels and tyres they use on the short take off and landing competitions.

Martin

Hi Martin - are you going to fit floats - pretend you are in Alaska ?

Fitting 'em is easy, work of minutes. 3 pre-fitted screw clamps and you're done.
Cutting to size and assembling the 'undreds of pieces is the 'orrible bit ☹️
Ciao, Doug

Good luck fitting them, then.

M

In which case; Yeah, like way down south!
Doug

America. It's my American friends call it, so I figure I can too,
Martin

Probably, what's a 'Murricay'?

Now I know why they say, "I'm retired, I don't have time!" I had a tip run with 6 garden sacks, bit of shopping, visit the caster, clear the doggy mess in the garden ready for the mower man and finally I was able to do some work! Insect stop doors? Are they those screen things they have in Murricay?

Martin

Hi Martin,
Just got back from a shopping tour 🙄 including delivering your packet to the local DHL 👍
Packet / Tracking number per PM.
Now to continue with Gisela's Insect Stop doors! 🤔 A PintheA, wouldn't have believed how complicated they could make such a simple thing!!
Cheers, Doug

Any ideas when it should be on its way, Doug? I have to clear a space for it! The Waverley is now upright in the outside store, behind my compressor and store of Ureol patternmaking block, which I got from a local rapid prototyping firm. It was originally the vac-form pattern for the DB7 dashboard!!

Martin

It's actually a repro of the Graupner cub from the old original kit building drawings I kept from 78. Pretty much as it was pictured on the original kit box except I did it with electrics this time. Showed it to a German Guy in the Heli club I used to be a member of and he was stoked, as it was the first R/C model he and his brother made in the 70s (mine as well). He has beautiful scale Robbe helcopters , (flown with a top line Graupner tray radio of course) having the contacts and being German. I think he's a service manager for BMW here as well.

The world's getting smaller and smaller every day John😉
Was wondering about the German registration, until I noticed that it was a Graupner model!
Cheers, Doug

It's a shame about the old ship's boilers, but I think she'll get new ones. There are still a few who know how to make them. As to what I'm going to do with a 62" long model I don't know. It only goes to deck beam level with a pair of beautifully made, if not feathering, paddle wheels. It needs a steam plant and all superstructure. I don't know that I have the time left to do all that!

Martin

Bit of a coincidence Doug, have the same 'cub' on the tail of my 'Super Cub' (found the pic on line and made a decal)
John B

No, not yet given up Martin, only registered and paid for the shipping online.
Must be your Vincent stuff coming tomorrow.👍
Soon as I have a tracking number I'll let you know.
Odd, when I get notifications from DHL at least it includes the name of the originator!

Have fun with the Waverley, and don't forget your donation to the new boilers for the original!!! (See thread on this site about that!)
Without 'em she, and the 'species', will be going extinct!😭
Cheers, Doug 😎

???So, you haven't yet given it to DHL? So why would they tell me it's on the way, I wonder...UNLESS, it's the huge box of heavy white metal castings for the Vincent from out latest caster. It doesn't after all say what the parcel is and the caster did say "shippers".
Oh well, no matter, I'll let you know when it arrives.

I'll put up a picture of the Waverley shortly under a new thread.


Martin

Hi Martin,
"And I've just had a notification from DHL that I'll get it tomorrow"
I'd be extremely surprised at that Martin, cos I've only just printed the packet label using the DHL online franking service!😮 It'll be going to the local Packet Shop tomorrow morning!
Yeah, the Piper Cub should make a good Trainer plane, supposed to be a very stable and forgiving flyer👍

Wow! Fantastic that with the Waverley👍 You'll have to build a boat-shed 😉
Can't wait to see her paddlin' away.

Marky: well, at least the pot is there. But I ate the contents😁, it was coffee cream by the way. Don't like yoghurt😝

Cheers, Doug 😎

And I've just had a notification from DHL that I'll get it tomorrow, so thanks for the quick service, Doug.
I did well enough at the club today to be told I need to get myself a trainer for "stick time", so I'd better get my finger out when it arrives. I thought I had sapace for it until an old friend/customer came to see me today and gave me a birthday present a bit early... a 62" long, 15" wide model of the Paddle steamer Waverley! I knew he had bought it a while back and we'd identified it, but never thought he'd present it to me! I have no idea where to put it!

Martin

Noticed the free pot of yoghurt is included (photo 1)😂😂

Yep! I bought it a good 30 years ago, talked into it by a sailing mate at the lake🤔, and I'm sure I will never build it! So Deep Joy for Martin and I have some 'spacial on the shelfimode'😉

Hi Doug - are those printwood sheets in the kit ? Must be a very old one
