why not use inexpensive aircraft engine

Post by Ben That » Tue, 27 Jul 1999 04:00:00



I want to know why it would be a bad idea to buy and extremely inexpensive
aircraft engine that I can get used off of eBay, instead of a $150 new
engine.  I want to chop into my old RC10 and turn it into an indestructable
gas car.  How big of a motor would be needed to race the car.  I race on a
free-for-all RC track, and gas power would be sweet.  I'll worry about
building a mounting bracket, but I want to know if it would be OK to put an
aircraft engine in the car.

Ben, didn't you see the other thread on this very topic? There is a
reason why the aircraft engine is cheaper (for the same amount of
cid's).
An airplane engine in a car would overheat and it would not give half
the performance compared to the specially designed car engine.

I didn't participate much in the previous discussion, but I suggest you
search back a few weeks.

Why not?  Lest we forget, standard RC plane .19 glow engines were used in
RC cars for many years using minimal clamp-on or screw-on heatsinks.  Good
marketing these days tends to narrow our perspective and spirit of
adventure by manipulating us to think we gotta get the current hot-flash
gadget.  Racing, of course, is a "latest gadget" activity.... as intended
by the manufacturer$.

Like I've said so many times before, tell me if you can make it work...I
want to do this too :)

Maybe a new class - aluminum RC10s with aircraft engines! :)

Check the dimensions of the engine mounting holes in relation to the
crankshaft.  Also, measure the length of the crankshaft.  You may need to
modify the mount, and use an old style clutch.... checkout the older cars.

clutch and flywheel could be a problem, also does not have a cooling head- no
prop there to cool it in a car, so you'll need a good performance head too.
Length and size another problem- a new hot gas engine is only about 100 bucks--
why bother ?

The powerband is unsuitable including many other limitations you read
here. People also don't use engines specifically designed for on-road
cars in off-road buggies.
