RE: Composite-ARF Integral, kinda build thread
Well my Integral flies beautifully (15 flights to date), very pleased with how everything worked out.
Weighs in at 4.9kg (10.8lbs), C of G currently at 191mm from LE with wings on, seems right to me. However I had to mix out pulling to the belly in knife edge in both directions.
My timer is set to 7 minutes and I'm using about 2800ma in this time. Current draw max at 85amps, prop runs up to 5900rpm. Nothing is getting hot although the ambient temperature is cool here at present (25 degrees celcius).
It is a basic C-ARF scheme with the following:
1. Hacker C50 14XL Comp, APC 20x15e
2. Jeti Spin 99
3. JR921 Rx (2.4) controlled by the JR DSX9 Tx (same as the X9303 2.4)
4. Digi Switch
5. Hyperion 2S 800mah Rx Pack
6. Hyperion 5S 5350mah Packs, running 10S
7. Futaba BLS 451 (Rudder), 2 x Futaba 9650 (Aileron) & 2 x Hitec 5245 (Elevator)
There have been heaps of pics and details give about the Integral so I note some details and pics of components that are a little different from what I have read about. Note none of these are my ideas I just copied the best ideas that I thought others had fom around the place:
1. Molded some 50x100mm scoops in the fuze out of CF - see pics. They provide negative pressure in the fuse to assist with cooling and they look groovy!!
2. Laminated the phenolic horns with CF to make them stiffer, I really like the effect.
3. Replaced the standard landing gear with Bolly FAI Electric, I thought the standard gear was way too stiff.
4. Made the rear mount removable to facilitate servicing of the gear box.
