Hi KAP2011,

did you made any changes on the elevator servo's? fi by replacing it with 1 servo and a closed loop?
I recently bought the same airplane and I found it pretty strange to use 2 servo's for elevator, they could have opted for 1 servo in the middle with fi a long control horn.
Oh yes I did the same, I replaced the tiny fueltank (felt like a 150 ml tank..) with a Dubro 12Oz/350 ml tank, that should be enough for 8/10 mins flying. Used the dremel indeed to largen the 2 frames which holds the fueltank
I was able to purchase a OS Max fs115a for a very good (dutch) price, so that will be my powerhouse. might be very overkill, we'll see...
