Hi Rcurtis
If youre C of G is at 3 3 /4 from the leading edge , that means that you had to of added weight in the engine compartment , my reciever was in front of the rudder and elevater sevoes . Beside the reciver was the retract servo . In my setup I have done something that most people don t do , and that is I use a extra servo for my steering ( nose gear ) , on a mix with my rudder . SO , in front of my reciever and retract control , I have two servos . One for the thouddle and one for the nose gear . In front of that I have my battery pack , dirrectly behind former A above the leading edge of the wing which is held in place by the tank and by the frames of the servos for the throuddle and nose gear
You will have no problems if you C of G is at 3 3/4 inchs from the leading edge , this does mean that you have to add weight underneath the engine , above the nosegear bay
By the way , don t forget to make , flat spots , on the wire struts where they are held in place by the setscrews .
My plane was heavy because I had 3 extra sevos , was finished in dope and its only my second plane ( I m learning )
The plane landed like a floater even at 10 LBS 10 OZ
Cheers
Mike
