i don't think it's the torque it's the speed of the starter...mine turns the prop fast enough to feel the air from it...all the torque you need is to get past the compression stroke...

your instructor should have a starter...i'm sure he'll let you use it...as your skills advance you can get one...i think for right now simple is the way to go...it won't be long and you'll be thinking witch plane to get next...

remember,keep it simple to start...who knows you might like the car thing better,then you'll have all that airplane stuff to sell on e-bay, the marketplace
