Just to confirm.. your gear is still much too heavy. Your Cub model is 17.5" span.. that's a little smaller than the Parkzone Ultra Micro Piper Cub
Given the lightweight structure involved then you need to aim for a similar slow flying performance as that of the PZ Cub.. That can only mean aiming for a weight similar to the PZ Cub...
The PZ Cub weighs 29g ready to fly including battery! With the gear you have in mind you will be lucky to bring the model in below 100g.. thats between 3 and 4 times heavier than the (slightly larger) PZ Cub.
Sure, with enough power it might 'fly', sort of, but it wont survive the first landing.
I'd get a bigger airframe, one of the 30" dumas kits would be more appropriate for the gear you have.
Sorry to be a killjoy
