Gas engine mounting diagram?

[machinebike]

Does anyone know ehre I could see pics of how the gas engine is mounted in to an RC and how the drive train operates?

Also, if the flywheel can be removed and not used?

the flywheel not only smooths the power delivery you could get away with it if you used drivetrain inertia, but it'd be lumpy and you'd increase the stress on the drivetrain.

it also provides cooling air to the head. if you remove this you must find another way to get either collant (water) or lots of air over the head to prevent it killing itself.

lastly, the flywheel has magnets in it that trigger teh coil to produce the spark. only wat to lose the flywheel is to use an eletronic ignition.


as far as mounting, alot of models use various types. Flat mount with carb in front, flat with carb in rear, low COG (heads tipped far toward front of car.
Baja uses the motor as part of the chassis. ect.....

Now I see your dilemma.

Fabe should be able to help you out here. His had another frame on top so he could position the motor.

Hi, thanks for the pichone:, looks like he doubled his frame because of how motor dips with out motor/block mount. I made a block that motor is bolted to, so regular frame is fine, I just need to extend the rear 3 inches for more clearance for flywheel.

What I don't understand is how he has a chain from engine running to the spur gears and if he is able to use two speeds.

If that is why he doubled the frame because of engine dips at the bottom, he could use aluminum squares to raise engine and do away with the double frame.
