Bustergrunt Posted September 21, 2016 Share Posted September 21, 2016 Fist tried with a Cox but changed to an AE engine, for that lovely diesel 'niff' Edited By Bustergrunt on 21/09/2016 14:44:34 Quote Link to comment Share on other sites More sharing options...

Colin Leighfield Posted September 21, 2016 Share Posted September 21, 2016 I've got a number of small diesels, must use them one day. Quote Link to comment Share on other sites More sharing options...
Andy G. Posted September 22, 2016 Share Posted September 22, 2016 Nice! One of those was my first ever power model. Built a few of Ray's models since though. Quote Link to comment Share on other sites More sharing options...
Dave Cunnington Posted November 24, 2020 Share Posted November 24, 2020 Fast forward to November 2020. I have enlarged the plan to 54" span, and intend to go from free flight to rc 4 channel, an interesting project in lockdown. Currently thinking of an old OS 25 FP to power it, but have OS 40 LA in the cupboard if required Edited By Dave Cunnington on 24/11/2020 22:05:07 Edited By Dave Cunnington on 24/11/2020 22:06:11 Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted November 24, 2020 Share Posted November 24, 2020 It’d probably fly on a Mills 1.3! That would be nice. Quote Link to comment Share on other sites More sharing options...
Matt Carlton Posted November 24, 2020 Share Posted November 24, 2020 Agree, a 25 would be more than enough, 54" is roughly J60 size and a lot less bulky. I reckon a .15 or even a .10 would work. Or, as Colin says, a Mills 1.3 or a PAW 09 or 15 maybe. Quote Link to comment Share on other sites More sharing options...

Dave Cunnington Posted December 19, 2020 Share Posted December 19, 2020 Slow progress, took a while to decide where to put everything and design the inside structure. The battery location is fluid, dependant upon C of G Quote Link to comment Share on other sites More sharing options...
EarlyBird Posted December 19, 2020 Share Posted December 19, 2020 An interesting project Dave. It looks like you are using lite ply, lack of balsa? Design changes add to the fun IMHO and scaling up even more so. I have yet to advance to scaling up and plan building but it will happen.

Dave Cunnington Posted December 19, 2020 Share Posted December 19, 2020 Steve, liteply front end and balsa rear for fuselage, see earlier pic. Hopefully this will be stronger as it's a 2X model and it should help with C of G, note that some of the inside structure is balsa. Quote Link to comment Share on other sites More sharing options...
Piers Bowlan Posted December 20, 2020 Share Posted December 20, 2020 A classic model Dave, a good idea to supersize it. I have Christian Moes electric Sky Gipsy twin plan from RCMW mag - too many models and not enough time! Just a question. Is the extra balsa platform raising the tank position necessary, as from the photo the centre of the tank looks well above the carb spraybar? I may be wrong 1) because the photo is deceptive 2) I am not really an engine man 3) probably doesn't make any difference anyway! I only queried it because I was concerned that a high tank position might flood your inverted engine. Also your inverted engine installation could potentially make disconnecting the glow clip after engine starting a little tricky. Just a thought Edited By Piers Bowlan on 20/12/2020 05:55:54 Quote Link to comment Share on other sites More sharing options...
Dave Cunnington Posted December 20, 2020 Share Posted December 20, 2020 Very good thoughts, Piers, thank you. In my limited flying experience I have only ever used upright engines. This one is inverted, which looks better, and means the sticking up engine head is not the initial point of contact in a "whoops" arrival. Yes, I am planning a remote connection for the glow stick. Regarding tank level, the current "floor " for the tank looks right, but I can always remove it after a final assessment. I am building everything internal onto this one fuselage side before adding the other. Regards DC Quote Link to comment Share on other sites More sharing options...
Piers Bowlan Posted December 20, 2020 Share Posted December 20, 2020 Another alternative Dave would be to mount the engine 'sidewinder style' which would might avoid damage to a sticking up cylinder head as well as obviating the need for a remote glow stick, but I expect you already considered that. It might also be an idea to drill a hole in the front ply former too before assembly, should the battery needs to go in the nose. Hope you don't mind me adding my 2p worth. Yes, I am doing the same thing with my Spateman build and adding it all onto one fuselage side before adding the other as I won't be able to get my fingers in after!

Dave Cunnington Posted December 20, 2020 Share Posted December 20, 2020 Any 2p is gratefully accepted Piers ! Yes, sidewinder is an option but I preferred either up or down........whatever, it can be a late decision, and the sidewinder would lift the carb up a bit , and also give room for a bigger pilot. Just for entertainment I've been playing with ideas. My son has a 3D printer and will provide me with a Dan Dare Pilot and a Mekon for the passenger compartment, so I wondered how it might look !

Dave Cunnington Posted December 20, 2020 Share Posted December 20, 2020 Cheers John. Yes staying home and staying safe, building stuff is keeping me sane. Trouble is, no flying = no crashes and my shed is getting too full up. Stay well yourself John, and say hello to Mark from me Rgds DC Quote Link to comment Share on other sites More sharing options...

I only queried it because I was concerned that a high tank position might flood your inverted engine. It may seem counter intuitive but an inverted 2 stroke is less likely to flood (or suffer hydraulic lock) than one mounted upright.

Dave Cunnington Posted January 19, 2021 Share Posted January 19, 2021 Thanks John, perhaps one day it might be, right now all I see is a large square box with wings ! Trust all still OK with you and yours ? Today I had my first Covid jab, superbly well organised NHS, and so far no effects ......but the required 15 minute wait afterwards seemed to drag Quote Link to comment Share on other sites More sharing options...
