746 watts = 1 HP

My AJ with the Eflight power 25 flew stronger than the Saito 40 not much but more. I also flew it with a 4 cell 3200 Lipo which had close 650 watts if i remember on a 14x4 APC cut down to 14"

I am looking at getting a Extreme flight extra 48" wing i think. 500 sq with about 8 ounces less than the my AJ. Mine has been crashed several times. 15 feet high in hover and speed control cuts out is good. had this happen several times with a castle 45 amp. What i learned is speed controls get hotter at mid throttle settings.

I have the eflight Leader below with a Saito 40 also. I have one more Saito 40 brand new for the EF Extra.
