my windstar wont fly

[pedsnurse]

it glides well but under power ( bec 550 motor with 1500 bat ) it goes down and will not fly up even with elevator input but will glide well when thrown

One of our locals has one -same problem - found that the prop
is to flimsy & goes flat under power = no thrust the supplier
eventually got him a better one & now it is operable . try holding
it at full throttle & see if thats it

Good luck
