I have a friend that uses the Tower Pro esc's and he claims he has not had a bad one yet and he's been using them for a while now in about 8 different planes. You are going to love the T-28, it's a great 2nd plane.

Well, if you want a good ESC, then I recommend a Castle Creations Thunderbird 36. Castle Creations speed controlls are high quality, and work very well each time you power up. Plus I like the tone they make while arming up. The Thunderbird controllers may not have as many programming features as the Phoenix line, but they work very well.

I'd put Castle Creations above all speed controlls out there. A bit pricy, but worth every penny.

Keithn4....not all the issue with the T-28 is from the ESC.... the issue is that the ESC was designed to operate only 1 digital servo and PZ install 2 digital servos. Those 2 digitial and the other 2 servos are working the BEC to death...literially. I am running the EFLite 25 pro ESC on mine (still) with a EFLITe 480 (1020kv) motor. I switched out my rudder servo to a standard servo....my motor died during a flight which is why a replaced/upgraded it.

Things I would do:

1) replace rudder servo to HS65MG
2) Change battery connectors to Deans
3) Remove the ESC from the foam nad use double sided tape to mount it so its not "buried" in the foam (which holds in heat)

HS55 is too small....the HS85 or HS65 works...MG is not a requirement...

I am using the stock prop...but on the stock motor is a little weak for the claimed 960kv....when mine died during a flight I replaced it with the EFlite 480 (1020kv)...I have had great experience with that motor on APC 10x7 E and APC 11x5.5 E props (Estarter, Eflite P-47, PZ Spitfire, Typhoon 3d)

has anyone still had issues with the plane after they replace a digital servo or added an extra BEC? Is it a sure fix or can there still be issues?

I replaced the stock ESC (after it smoked with another EFlite 25) and 1 digital servo with the HS65MG and have not had an issue since... and I fly WOT the entire flight and treat her like a 3d plane... always doing loops, inverted, rolls, and combos....so I am always working the servos... and I did NOT add a BEC... the BEC is only needed if you want to keep the two digital servo in her.

I noticed Dimension Engineering's BEC do not appear suitable for the BEC change out. Any other ideas?
