renbo Posted February 26, 2012 Share Posted February 26, 2012 g'day all. renbo from qld , i am building a radial powered scaled sopwith hope to have it flying in about a year,depending on work ,money, anyone like this sort of thing ? Link to comment Share on other sites More sharing options...
Bandit12 Posted February 26, 2012 Share Posted February 26, 2012 Love the idea, and have been dreaming of doing a full scale Pup....the problem really lies in the engine. Which one are you doing? Plans or kit? Link to comment Share on other sites More sharing options...

facthunter Posted February 26, 2012 Share Posted February 26, 2012 Taking on a fair bit there. I don't fhink you will have any lack of interest. At that scale what horsepower do you think you will need and what engine have you chosen? Nev Link to comment Share on other sites More sharing options...

Hi Renbo, Sounds brilliant - good luck with it! There is a guy in Melbourne building a Sopwith Snipe replica - you may find some tips from him. His blog is here :- http://www.theaerodrome.com/forum/replica-aircraft/36007-sopwith-snipe-project.html All the best - upload some pix at various stages so we can see! Cheers Neil Link to comment Share on other sites More sharing options...
renbo Posted February 27, 2012 Author Share Posted February 27, 2012 yeh ,mine is nothing like the snipe its the real m'coy mines just a small as it can be UL i will put some pics up ,but have to work out how to shrink them cause it wont upload any,i have tried Link to comment Share on other sites More sharing options...
facthunter Posted February 27, 2012 Share Posted February 27, 2012 Many of these very attractive planes when scaled down can become very hard to fly. It's no good having one if you are scared to fly it so investigate the handling qualities of the plane you propose to build in it's final form. Some of them are light tnough to build almost full size, or in some instances can be full size. Nearly all of them had a "rotary" radial engine . These are four stroke engines that have a stationary crankshaft and the engine (with the propeller attached) rotates about the crankshaft. These give them a lot of their character where they sound great have a lot of torque and therfore spin a very large propeller, giving them a good take-off and climb performance. No-one has replicated one of these in miniature as far as I am aware, although there are some full sized ones running. Scaled examples will have the usual drag, and need a fair bit of torque from a " largish" propeller to fly well. A geared motor will work better than a direct drive one in this situation. The usual control difficulty is directional... Nev Link to comment Share on other sites More sharing options...
