hi all
i need some advice with my wren 54, the problem i have is it doesnt produce much power, to give you an idea , it just about gets my boomerang out of our field (i fly from the bickley club), it then requires a nice shallow climbout but does pick up speed for a half decent flight..
first the history.... it began life in a helicopter which ran realy well, ample power for the heli.... now, ive taken it from the heli and put it into the boomerang, before doing this i spoke to wren about any changes, to which they advised a PT wheel change and a cone along with some settings changed in the ecu... i sent it to wren and after looking at it they suggested just adding the tail cone and see how it goes. the ecu settings are now at, max speed 160.000... max temp 850. acceleration 7 , , deceleration 7... . its been running ok but way down on power..... would it be the PT wheel being different?, are they different?, if so would anyone be willing to change it for me, i dont think wren were too interested due to its history., it was put together by an undesirable to put it politely...

comments please guys

thanks
