Have a stock T-28 with a bad motor. Going to put a TR 35-42D 1000kv in it, which esc should I use the E-flite 40 amp pro or the Turnigy Plush 40 amp?

Thanks,

It won't need a huge prop on 3s to approach 40A, so I'd say the E-flite is the safer bet... can the Turnigy really cope with its rated 40A. Even with the E-flite you need to ensure that you are NOT drawing more than 40A! (30-35A would be safer to give yourself a small safety margin).... otherwise fit a 60A ESC.

Are you talking about the foamie Park Zone T28? If so, the 35-42 is WAY ovekill for that plane. Will be very nose heavy. I would look into the 35-36-1400 or 35-36-910 depending on what prop you decide to run.
I have a 39 1/2" w/s GP P47 Balsa plane that I run the 35-36-910 on 4S with a 10X7E APC prop, and the amperage draw is only 24 amps max static, and the thing is a rocket at half throttle. The T28 Foamie doesn't weigh anywhere near what the P47 does, so would be perfect.
I used to have the 1400kv version that I ran on 3S, with a 9X6E prop, and the amperage draw was still under 30 amps, but it chewed batteries up kinda quick. I only got a 5 min flight out of a 2650ma 3S pack.

As far as the Plush 40, I'm running 3 of them right now, and I haven't had any problems. Can't beat them for $22.00

I was given two motors the 35-42 1000kv and the 35-36 900kv. Will go with the 35-36. Any other advice would be appreciated.

Thanks,

Try the 35-36-910 with a 10X7E prop to start, you might want to step up to 4S if you want more speed. It will fly just fine on 3S though. I have the Hobby-Lobby Stinson Voyager that I fly with this same setup, and it flies good on 3S. It was a bit too slow for my liking on my P47, that's why I went up to 4S, but the T28 is a bit lighter, so it should be pretty fast.
My Stinson gets about 7 minutes of flight time on a 2650ma pack, with around 600-700ma to spare.
Output on 3S with the 10X7E prop is just a tiny bit under 200 watts, on 4S with the same prop is about 325 watts. It all depends on the type of flying you want to do, and how long of a flight time you're after.

Hope this helps.
