Attaching the motor to a T-52

One method:

Here is one method for attaching a motor to an R/C model which uses coroplast fuselage doublers, as with the T-52:

like this:

Note: I wouldn't recommend using double-sided tape between the coroplast fuselage doublers and the motor if this is a trainer. Not having the tape between the motor & coroplast will allow the motor to move back during a nose-in crash, adding an extra measure of durability to your T-52. Adding the double sided tape is recommended when using the Master Airscrew drive unit (because of the torque of the motor, the drive unit tends to rotate if you don't add a bit of tape). After you tighten up the cable ties, you trim off the excess.
