RE: Composite-ARF Integral, kinda build thread
I replaced the metal pin with a carbon rodsaved 6 grams. The carbon rod had to be sanded a bit to fitdon't recall the size of the rod used. 300-ish flights with this on electric power. I probably would not use the carbon rod if glow powered, or it would need to be replaced frequently.
Rudder servo in tail: If you are going electric you will need to be careful with weight in the tail.
Concur with Jasonequipment selection and minimal glue control the weight in an ARF. The Integral I am flying started out as an all white version, and relative to other Integrals I have seen was about 3 oz. heavier to start. With careful equipment selection, replacement of the wing tube with a PBG tube, replacement of the LG with a Bolly F3A large and with the trim painted on, I came out at 10#6oz using the following equipment: Hacker C50-13XL COMP, Budd Mount, Hacker COMP ESC, FlightPower 5350, APC 20.5x14, TT spinner, Jaccio regulator, TP910 Rx battery, 5014 Futaba Rx, 9650's in the stab, 9550's on ailerons and a BLS-451 on rudder.
Out of the box alignment was very good. No trim issues with CG at 162mm from the wing LE.
I really like this airplane.
See you in Muncie.
