RE: Official Losi 26cc 5IVE-T Thread
it's called torque effect, it effects helicopters adversely that's why they have tail rotors to counter the torque effect....Newtons law states that an action has an equal an opposite reaction...so engine crankshaft applies power spinning one way so the chassis wants to spin the other........I thought this might have been a problem with the ferox that uses the same engine axis but seeing videos of it going round a track and flying off jumps it doesn't look to yaw down on one side, reason being is the centre diff spins the opposite way so you have another action/reaction, it's counter rotating and must supply enough opposite reaction to make it neutral.
