Good advice 3DownLow.
In addition set the ESC for soft-start if the plane is not strong enough. The torque when throttling is huge, and might destroy lausy constructions.
A friend of mine who use the Elite18 in a motorglider have set soft-brake for 2 seconds before 100% brake is applied. This is to avoid destroying the plane due to excessive torque

It is a pity so few people have discovered the nice power from those motors...
