Range Safety Launch? by canabus Fleet Admiral!   Posted: 12 days ago
Hi The 382 was a Fire Float Mk1(40 foot) (No. 90) converted in Feb 1950 to a Seaplane Tender. Max speed 21 knots. The MFA 800's are 5167 rpm( unloaded) @ 12 volts/ 5.3 Amps. Replacing these with 3639-750Kv brushless on 2S Lipo batteries(7.2 volts) would give you 5400 rpm( unloaded). 2S 4000mah 25C Lipo's(one for each motor) weigh 221 grams each. Canabus

Range Safety Launch? by NPJ Fleet Admiral!   Posted: 12 days ago
The ‘Range Safety Launch’…………. Intro. I am now the owner of this boat. Wooden, good hull lines and hull paint work but needing to be finished. I am told that it looks like it started life as a kit, but has had considerable modification to at least the above deck layout and detail. Advice is that it could be a rather simplified Range Safety Launch, but maybe I can use a little ‘artistic licence’ and just make it look interesting and capable. There are two main reasons for sharing this project. 1. I will undoubtedly need guidance 2. Maybe some of the information will assist others The hull is 44 inches ( 112cm ) long and 14 inches (36cm ) wide, it has two brushed MFA Torpedo 800 motors………. and weighs in currently at 15 lbs 4ozs (6.91 kgs). It is large enough for me to be able to work on reasonably comfortably and apart from the cabin/upper deck areas to be ‘improved’, I aim to introduce sound, lighting, active radar sweep, search light, together with maybe a deck hoist and water /fire monitor appliance. At my age it is difficult to tell the difference between wishful thinking and dementing…… However, the prime aim is to try and achieve at least some of this whilst having the boat usable during the current ‘season’. There is so much knowledge, good will and help available on this site that even before I touched a thing, information came pouring in. If anyone feels like making a contribution then please just ‘pile in’. Have ordered some parts so next time should have something to show. NPJ.

RS 545 Motors by figtree7nts Fleet Admiral!   Posted: 21 days ago
Greetings Skipper, Welcome about! Why not try these motors! I have them in my Dumas San Pedro. They work great! https://www.cornwallmodelboats.co.uk/acatalog/MFA-919D251.ht... Regards' Ed

Spektrum, new, useless... by Westquay Fleet Admiral!   Posted: 28 days ago
I haven't heard of that over here, Doug, but it sounds like something I would consider, as it covers more. Last time I tried I couldn't get any sense out of the brokers at all. One couldn't even understand what a "model aircraft" was! Didn't exactly fill me with confidence that I'd end up with anything usable. I think if the British Model Flying Association was still the Society of Model Aeronautical Engineers I would be far more likely to approach them, but the BMFA can go to hell with its naff logo too. Still don't see where chucking a foamy off a deserted cliff needs insurance! And boats, round here? Nah. This is Fenland, Nothing and nobody. You need CAA permission for heavy kites over here too. Anything over 11Kg, I think, or a certain size. My old chum built a 1/4 scale Tiger Moth, with a 35cc petrol engine in it. He also has a 1/4 scale Stampe. Huge things. Martin

Spektrum, new, useless... by pmdevlin Fleet Admiral!   Posted: 28 days ago
you don't have to join a club . BMFA (British model flying association) will take none club members, you join as a country member. You don't actually have to take the proficiency test, but most clubs insist on it. Not only does it demonstrate a basic understanding, and basic competency of flight, electric, ic, petrol or free flight, its also an understanding of caa rules and safety. There is also the LMA (Large model association) which also carries public liability insurance. Flying without insurance just isn't worth the risk, imagine, on a nice hillside, nobody around, up on a thermal, and the tx fails, the soarer comes down, (anywhere as there is now no control) and hits an animal, or worse, a walker, would the £34 for a full year public liability insurance still seem expensive when you are hauled in court facing prosecution and possible imprisonment? Same with an rc boat, particularly a fast one, receiver packs in, boat is out of control, and little jonny has his hands in the water as it hits the bank, still don't think insurance is worthwhile? I bet a lot of people insure their mobile phone for more than £34 a year, by the way, Im sure BMFA insurance also covers other rc disciplines 👍

Spektrum, new, useless... by Wingcoax Sub-Lieutenant   Posted: 28 days ago
Martin, Please note that your comment about "no insurance" is misleading. All model flyers should be insured and proved competent by passing at least the BMFA "A"test. This is speaking as a former instructor and "B"certificate holder.

Hellen Fishing Boat by canabus Fleet Admiral!   Posted: 1 month ago
Hi All This year I bought an unstarted kit, but, sold it to a club member. A month later one of the club member wish to swap for a faster boat and as my Sea Commander required a repaint and fittings. I thought a swap for a very good working Hellen was a good deal. So are making a dingy and replacing the broken prop with a brass one I had my second Hellen for the year. Three weeks ago another Hellen pops up on Gumtree(aka EBAY), so it was to cheap not to buy it. While waiting for it to come, I made a new stand, a dingy with oars and a set of fenders. When it arrive the mast where laying on the deck broken, but , the posted pics show that. The motor is a 11 to 1 geared MFA Como 919 D which runs OK. A spare new plastic prop. Started on the repairs, like the keel and deck around the mast bases. The aft mast was broken in half, so I brass sleeved it. The aft sail was missing and the forward sail was all glued up, so I bin it. So this is the boat pics so far. Canabus

Which motor by figtree7nts Fleet Admiral!   Posted: 1 month ago
Hi Neil, I use MFA/ComoDrill Torpedo 500. On my Tugs and they have enough power! I use the 2.5:1 g/box at 12 volts. It gives about 13350 rpm's http://www. style='background-color:yellow;'>mfacomodrills.com/gearboxes/918d_series.html Cheers, Ed

Mini Olympus gearbox by RNinMunich Fleet Admiral!   Posted: 2 months ago
Have you asked here? https://www. style='background-color:yellow;'>mfacomodrills.com/gearboxes/gearboxes.html MFA made it in the first place. Happy hunting. Doug 😎

Spektrum, new, useless... by pmdevlin Fleet Admiral!   Posted: 2 months ago
IFound out today via bmfa that horizon hobbies who looked after spectrum warranties and repairs are back in uk with darbrorc who are just outside stoke on Trent. Maybe they can get the tx tested and fixed? Several years ago I had a couple of frysky tx and they needed to be set up on a pc don’t know if this is still the case?

Intermittent radio problems by boaty Captain   Posted: 2 months ago
😁Had this problem back in the mid 1990s with an MFA Spearfish with 12 volt set up and 40 MHz radio. In one part of the lake it appeared to lose radio contact which was puzzling. A fellow model boat user said he thought it was interference from radios in taxis that were operating close by. Never really got to the bottom of it but the fellow enthusiasts explanation appeared to have logic to it due to the close taxi operation. Boaty😁

46"Vosper Crash Tender Lesro by Ianh Petty Officer   Posted: 2 months ago
Have a query here busy with Vosper 46" I intend to put a twin drive in using aP94 electronic controller ex action electronics Some of the design says to use 2 Graupner 900 speed motor these are no longer available any suggestions as I need the gel cells for ballast I think MFA Come 850's might be overkill Thanks

S 100 Schnellboot RC build by kmbcsecretary Fleet Admiral!   Posted: 3 months ago
Hi Doug yes I did try the three prop set up first MFA 385's if I remember correctly running on a electronize 30 speed controler.but replaced them with a Graupner eco 500 I think ?

It's a sad day!. by Novagsi0 Captain   Posted: 3 months ago
True Bloke. (thanks!!) The huntsman is my passion the boat above is a larger scale Sordsman 15cc. I sailed this last night as a ode to my father on what would have been his birthday we started this 30 years ago only finished in the last few months ready for the 14-May. wish it could have been IC but a large 850MFA gets it plaining (just), for an hour on lipo's instead. My father use to run FIA Rossi engines on gear boxes and do NAVIGA speed I think it was called. But there is a draw of ED Hunters, ED racers, diesel engines, Basil Miles Engines etc.

Additional supression added. by Novagsi0 Captain   Posted: 3 months ago
Following on from comments here and a mail from Como MFA i've added a 0.22uF Cap to the motor terminals. Hopefully that will see the back of the uncontrolled mounting the side of the pool disasters.
