Thanks, that was really helpful. I learned more from reading your post than I have from any other source. I like your idea for a building series of dvds. I know from reading these posts you could make a small fortune by doing an in depth electric video.

I figured out one of my problems. I thought that Eflite was refering to APC E props when in fact they were suggesting their own Eflite Slow Flyer E props. I took off the APC 11x5.5 E prop and switched it out with an APC 10x4.7 SF it does make a difference. I am still baffled though, I took some rpm readings in the garage and the 400xt turns an APC 10x3.8 SF at 6400 rpm and the 450 turned an APC 10x4.7 SF at 6300 rpm this is a $29 motor vs a $65 motor and so far the value goes to the $29 motor. I know that I need to get a watt meter and get all scientific and mathmatical, but for me the magic is in the flying. I had my lhs order Eflite's watt meter. I think you are right and I might have some worn out lipos. I thought lipos were supposed to last along time. I started flying electrics about a year ago and I purchased 3ea TP 1320 3 cells at the same time or with in about a month, I dont know how many flights I put on them all but I went through 5 planes and now am on my 6th. Some days I would get about three flights per pack with charging between flights on each lipo. I should have paid more attention to this stuff in the begining but over the last year I just kept buying planes that were the same weight and size so that I didnt have to spend any more money on gear. I actually have two sets of the same gear so that I could always have a plane ready to fly. My current plane is about 5oz heavier than what I usually fly so that was the reason why I wanted to get a bigger motor.

Thanks again, cant wait to get the watt meter and start learning how to really use these toys.
