Krill 41% Extra 330SC Build
Well the nice guys from Krill delivered this baby to me. Build will take a little time as I am pretty busy this month, but have made a start.
Setup will be: DLE170 Zimmerman Canisters 4 x Futaba BLS157 HV on the stabs 2 x Futaba BLS157 HV on the Rudder 4 x MKS767 HV on each wing - yes 4 apparently required to save the gear trains!!! Powerbox Champion RRS 2 x Futaba 14CH Rxs 2 x 4500Mah 2S Lipos |

Using 1.75" arms on the stabs and getting about 48-50deg of movement.

Why a DLE 170?

Sub'ed. Seems like a lot of high powered servos.

I agree, but talking to Ivo at Krill, he recommends having that number to avoid stripping the gears. I was initially hoping to get away with 3 in the wing and might even try that to start with. Probably could just have one on each stab, but they are big surfaces so an extra won't hurt. I know from previous Krill owners that they have a tendency to eat gear trains?

Don't know how this compares to other planes, but here are a couple of photos of the ailerons to show their size. The movement available is about 50degs and I haven't removed any material from the hinge slots. With a 1.75" arm and the lower control arm hold, I am getting around 45degs with my ATVs at 130. For my limited 3D that will be plenty!!!

I think the difference is all in the counterbalances. I tried to run a single 8911HV on the stab of my Krill Sukhoi and with a 1.5 arm, got flutter, so went to 2 servos. My comp arf 330SC has a bigger counter balance and has been very happy with a single 8911HV (1.5" arm). Same story on the ailerons. The comp arf measure 8.5" @ the root and 9" @ the tip including the comparatively bigger counter balance and again have 130 flights on 2 servos per aileron with no issues.
