It’s been a while since the boat had it’s maiden voyage on the lake at St. Albans and I’m pleased to report that it looks really good in the water and goes like stink if you open up the throttle. Sadly I still don’t have any decent video of the boat yet as I can’t film and drive the thing at the same time, but I do have some static wide shots from my GoPro. When I do the video I’ll ask a cameraman mate to do the honours, maybe I’ll put the GoPro on the bow and then the stern to get some low action shots…the storyboard is already building in my head!! These early runs were great as they showed up some minor problems that needed attending to. I found that it needed ballasting slightly as it was not sitting on the waterline evenly from side to side so I flattened out some old lead water pipe and cut it into small sections so that I could add ballast incrementally. I did this in the ‘domestic test tank’ and once I was happy the lead pieces were fixed in place inside the hull with some super strong double sided tape. The ESC needed a little programming adjustment because I had forgotten to set the low battery level point to ‘off’ as I am using NiMh batteries and not LiPo’s , that was the cause of the short initial run time on the first outing…..DOH !! The batteries are now held in place by Velcro straps on some bearers that I added, otherwise a battery change involved cutting cable ties and replacing them at the lakeside…not very practical. The volt/amp/watt meter is also now on a proper bracket so that the display is more readable. I have also changed the charging connection from the nasty Tamiya connector to a nice little panel mount XT 60 connector that HobbyKing sell, it comes with a handy blanking plug that I have drilled for a retaining cord. I have also finally got around to upgrading the firmware on my Turnigy i6 radio to the 10 channel version so that I can assign the lighting to the switches properly and have the rotation of the searchlight on one of the two rotary knobs. I can use the old 6 channel RX in the new boat….blog coming soon.
Hi Guys If you use Hobbyking 3648-1450kv 35mm brushless on a 4S 5800mah Lipo, 100Amp ESC and a 2 blade 40mm prop it will go like the clappers !!! You would have to make it from plywood to take 1600Watts(about 2HP @ 21,000 rpm(unloaded)!!! Canabus
Hi Westquay I had the F1 outboard from Hobbyking which had a 28mm 3000kv motor. I ran it on 3S with a 45Amp ESC. Great unit, but, clean and regrease after each days running. Also they did not have spare flex drives. The flex drives do not last very long. I had it on a 24" shallow vee, trim and balance right would run at full speed just on the prop!!! Totally insane to drive. I did not install to 2836-3700kv with 700Watts!!! Canabus
Spitfires in this case are kneeler o/b powered vintage race boats. I thought I had 2 on the go, one for me and one for someone else, but I just found one! Oh well, one's enough. The dollies are needed to look like they're driving these things. They accept 1/6th scale dollies and I even have a suit of clothes bought off ebay for him! I bought an outboard motor from Hobbyking without fitted motor for bugger all, but now see that the same thing is £45 quid without brushless, which needs to be a 28mm watercooled inrunner. I'm going to need one of the those to fit the shaft and all that, but can only find one for 31 quid. It seems HK have been upping their prices lately! Do you have any reccomendations for where to get such an animal a little cheaper? I need the motor, I now realise, to build the dummy Godiva casing round it. It's supposed to be around 2300Kv, but the only ones HK have are more. Is that very important? Martin
Of course, Doug, but you have to admit the mass line-ups look bloody realistic. I have 2 Spitfires in build and have even found a couple of dollies to drive them. And, I bought a HobbyKing o'b without motor. So info on installing a brushless will be required once the installation begins. I' couldn't leave the o/b alone, so I had to turn it into a Godiva 40 as built by Coventry Climax. Not much current news but their forum is still going up to date. I very much doubt that any English have taken it up yet. No evidence of it on the forum. Of course, whilst there are a few (rather expensive) kits, most are scratchbuilt and very nicely too. That's what I like about 152 vo. Martin The almost legendary Coventry Climax powered Godiva 40.
Hobbyking do a nice brushless outboard, which, if you're not ready for the whole thing, comes without a motor, so you can set up and then choose a smallish motor. It's very nicely made with a CNC leg and very thin GRP cover. I think mine was £17 without the motor which is about 7 quid from them, but their prices change a lot and often. The 152VO boys know all about outboards. It's their very raison d'etre. Can't help with the lifeboat. I always give to the charity, but have no interest in them as models. Try this and get immediately hooked!:-http://www.152vo.de/ Martin
Sort of cross between HobbyKing and Woolworths Martin! I just used their German site to buy selections of LEDs and resistors, thanks to a tip from Ed (figtree!) Cheers, Doug 😎 https://www.banggood.com/buy/uk.html?sbc=1 PS Stuff just arrived, only ordered on Satterday arternoon. Wasn't scheduled until Wednesday 😊
The flysky fsi6/tgy i6 upgrades to ten channels for the price of a of Data cable at £3.00 from hobbyking and a 10 channel telemetry rx £15.00 some sensers at £7.00 so it monitors main battery voltage and RPM which is very useful especially the voltage . RPM handy for prop choosing I have done my tx and now all I have to do is figure out what to do with the other channels better to many than not enough Good set and expansion at low cost 👍
Mornin' 😲Martin, Yeah, I thought the TX was good for both too. I bought it 'off the shelf' in Conrad, in Tal here in Munich. Then much later in the small print on Spektrum's website I read - "DSM2 not for EU models'! 😡 Odd! UK was also in the EU then!? Will PM U wot I paid for it. Came from HobbyKing - Where else? No wonder model shops are dying like flies 🤔 You're right about plane size. Last one I built (a few decades ago🤔) was the little Simprop 'Zaunkönig' (= Wren). After I 'd built it I looked at the short double decker wings, about the length of my forearm!, and cut the top plane down the middle and added a centre section to about double the span for more lift, and hopefully to make it less twitchy.See pics. Last pic is the sad mucky state when I found it in the cellar last year. Shortly after that I moved to Munich and had my hands full with other concerns. Still got the Enya 047 Glowplug and fuel tank intended for it somewhere! Might try fitting a brushless instead. When I was a kid, around 13 / 14, I made a scratch built (no plan - just 'thinks'!) free flight (RC? Wossat?) soarer. Basically 3 planks of 36x4x1/4" hard balsa. 72" span, 36" tail boom fuselage. That was BIG in those days. Bloody thing climbed and flew so well on it's Maiden that the last I saw of it was at zig thousand(?) feet over Hemswell Cliff in Lincolnshire heading due east at a rate of knots 🤔 Had launched it from the top of the water tower at RAF Hemswell, Dad was a Crew Chief on Thor missiles there. Hope someone in Denmark or Norway had some fun with it 😉 I've often wondered where it ended up. Must dig my Flying Boat / Wing outta the cellar! BTW: the foam wing/flying boat and Catalina arrived as kits with the foam cutting already done😁 Cheers, Doug 😎 PS: I still have the Glow-plugs I bought for the 'Zaunkönig', intend to try them as ignition for Flash Paper firing of depth charge throwers and guns on my destroyer. One has to have dreams or there's no progress! 😁 G'night all 😎
