has anyone converted a rc car motor to plane, ands if so how?

The main shaft is too short for plane use. also the shaft dia. may be to small as well. the prop won't fit. Dennis

can the shaft be changed or modified

the only I have ever done like that, was in a ducted fan set-up...

I thought the os.15 was weak so I put in a bigger car motor

what is your setup going to be ??? that might help some other people answer your ?

hi i have a vertex 2.95cc nitro engine out of a tranosaurus truck,
 and was wondering if i could convert it for a 46 size trainer i have . how did the ducted fan set up work was it powerful enough and what kind of plane did it go into?

when I did the swap.. I went from a 400' roll out to a 100'

topend was was gained big time.. I was happy with and went into a kyosho f-16

but looking at the numbers on the .18 vertex I doubt youll have the plower to pull a 40 sized trainer your best bet is to buy a another glow motor and save the hassle for something else

there are alot of of cheap options out just look around

ive converted a boat engine for plane use, (aquacraft 18) it works just fine, but is nowhere near powerful enough to pull a 40 sized trainer

cheers guys think ill buy another motor

How did you mod the boat engine i have one but i rhought they needed to be liquid cooled...i havent found much information on this topic...so i think its not done because the rpm's r about half that of an airplane motor and the shaft is the wrong size...i would think that you could fix the rpm proboem by putting a steeper bigger prop allbe mounted and balanced at home???

It's not worth the effort, even if it does work. Think about what your time is worth- maybe $15 an hour? So you make adapters and take off the water jacket and mod the plane for mounting, spending maybe 10 hours on the project. $150 worth of your time and the loss of the boat engine to avoid buying a $139 engine? It doesn't make sense.
