Subject says it all, what is the largest engine available for remote controlled planes with out actually buying a plane engine... which i know a few have thought of

Any links or photos??

I don't believe there are very many gaps in power plant sizes beginning with CO2 motors and Cox .010ci through 36 cylinder turbo charged WWII engines. Where Satio and OS leave off, 3W takes over. Where 3W ends, Rotax fills in... and on it goes. There may be some thin spots in the power plant size-line but I'd guess there are very few if any gaps.

3W's largest... http://www.3w-modellmotoren.com/engl...r404.html~main

Rotax's smallest... http://www.rotax.com/en/Engine/2004/...ine.Models.htm

wow - that is a big motor.

I looked through their engines and 3W has one for ~9k (eur) that has enough HP to probably fly a small plane with a person in it....

Do a little googling on the Cri-Cri you'll find some very interesting twin engine home builts, if you want to see what appear very similar to our hobby engines flying a small manned craft. These certainly aren't all that large, but thought you might enjoy.

i was absolutely astonished that thing could climb vertically that fast and bank that hard....

A Ford V-6 comes to mind for some rpv stuff.

Hi Bill,
The largest number of cylinders I could think off was in the P&W R4360 radial . This had 28 cylinders.

Do you have a link for the 36 cylinder engine ? The reason I ask is that I have been compiling various documents on operational WW II aircraft engines and it would be good to add some more info.

All the best

Colin

Go to google and type 36 cylinder aircraft engine, There are a couple of articles about the engine.

this is one beautiful engine... Moki 400cc Radial.. fantastic sound..
