Default Re: QQ 120 inch only took 1.5 years to build...

Hi Craig,

Move the outboard servo to middle, it will help with your snaps
I use AirModels 31x12, I have also flown 32x10, if noise is not an issue, try the AM 31x12, it will bring it even more alive! I use two 3000 LIMN. Your batteries are good

Pipe installation is not that difficult on this plane. If you ever decided to do it, let me know if I can help out.

Now that mine is dialed in, I really am enjoying it. I did an article on FG about RE3 and DA170 performance and actually was done on the same plane, when you get a chance, take a look at it and compare the performance to yours and see if it is worth the change or not. Plus it will help your CG as well.

Good luck buddy,
Reza

Thanks for posting. I thought about tuned pipes but didn't want to hassle with them... The ks95's (rear exit) work well and it has plenty of power on the up-lines with the 32-10. What prop are you using or do you recommend???

I put two servos on each wing. One on the outboard and one inboard (I did not use one in the middle). I'm using a weatronic receiver right now with 3800 mah duralite manganese packs. The weatronic reports 10.85 max amps and the voltage never dropped below 6.1 volts.
