My Pulsr XT 40 is powered by the E-flite Power 46 motor, APC 13X6.5 prop, 5S 3750mah, Castle 80 amp ESC (overkill but that's what I had). I
was really afraid of getting a Pulse considering my previous issues but I thought if I didn't overpower it then I wouldn't have the issues. So far
it's true.

The Pulse XT 40 is a smaller plane and flies like it. I will says that it flies like it's bigger brothers only on a smaller scale. The bigger planes will
be more wind friendly and will ground handle (handle bumps and holes on the ground) better. We installed 4" air filled Dubro tires on our planes
because our field was rather rough. I used the stock tires of the Pulse 40 from the beginning and so far no issues.

I've never turned the landing gear around on any of my Pulses. I think if the CG is moved back far enough you will not have issues with nose
overs. I had the OS 91 FX in my Pulse XT 60s and only had to add 1/2oz of lead to the tail to get the CG on the suggested spot.
