Here is the info from my first multirotor build.
Spektrum DX6i TX, All throws 100% Throttle trim down maximum. Dual rate set at 40% with 20% Expo. Full rate 100% no expo.
radio battery is 8.4v 270mAH LIPO.
Orange R610 receiver with casing removed.
KK2 controller flashed with 1.5 firmware. Mounted on two layers of double sided foam tape with 5mm low density foam in between. http://www.hobbyking.com/hobbyking/s...723&aff=850663
KK2 Settings are;
Acc Pitch 20
Acc roll 21
Height D 15
D limit 30
Voltage sensor 66 for 2 cell, 100 for three cell.
Scaling; Roll 80
I may increase the pitch and roll scaling as I learn to control it better, but don't need dual rates at the moment as high rate is ok on these settings.
Motor mounts epoxied to balsa arms (leading edges from an old glider kit) about 12 x 15mm, and strong thread tied around the outside of the balsa arm and through the mount holes then glued with superglue.
