T28 Trojan Replacement Motor
Can anyone recommend a drop in ESC and motor from Hobbypartz.com that would drop into the Trojan t-28?
I was thinking of these and I would prerfer not having to do major modification if possible.

Several sites have the replacement motor mounts, ESCs and motors for the T-28 & F-4U; e.g., www.atlantahobby.com

Beaner,
Thanks for the reply but my objective is to not pay $60 for a motor that Im probably going to trash as Im new. Im sure people are buying hobbyking or hobby partz motors and making them work in the T28.... for 1/3 of the cost of an OEM/Parkzone motor.

The replacement motors for the T-28 / F-4U are especially made for those acft so they fit with the cowlings of acft (using their standard motor mounts). It's not the 'standard' E-flite 480 form / fit. The motor is difficult to 'trash', but the shafts can easily be replaced - hmm how do I know 
If care is taken to properly loosen the set screws, tap out the old shaft, insert the new shaft, and tighten the set screws and add the collar.

RE: T28 Trojan Replacement Motor
Iknow this post is OLD, but how hard do you have to "tap" the shaft to get it out?I figured that I would have to after i loosened the set screws and it didn't come out. Also, I assume I tap the front of the shaft (the propeller end) so it slides out the back of the motor. RIght?

Never "tap" a shaft out.. use a vise or drill press and "push" the shaft through....using a drift on the shaft, or an oversize socket as a spacer on the housing.

RE: T28 Trojan Replacement Motor
Using a socket on the frame of the motor is a sure way to damage the ball bearings, what you need is a receiver for the shaft that is slightly larger than its diameter. Press the shaft of the motor into that receiver (using a drill press ideally) after removing all set screws and collars and any e-clips that may be there. OTOH lots of guys just go ahead and replace all the bearings when replacing a shaft since they're cheap vs. starting up your newly rebuilt motor and hearing horrible noises come out. Just remember when pressing a bearing on or off to NOT let the balls and races take the pressure, only the center cone.
