Hitec Optic 6 / BH Stuka / flap setup
I am considering buying the BH Ju-87B Stuka ARF 120FS/EP, which has an unusual wing arrangment, which uses six servos, two for ailerons and four for the unusual split flaps. I have a question about how to wire the flaps. I was thinking about connecting the two servos on each side in parallel by soldering the wire from one servo to like colors from the other, then paralleling the servos on the other side the same way, eventually ending with a single connector with all all four servos parallel wired plugged into CH6.
Is this workable, or would it create a load problem for the RX channel? Or is there a better way to handle this problem? Tkx.

2. Model &type of RX not mentioned, suggest best toparallel battery with the flap servos to better spread the high load at low flap setting.
Optima Transceiver (RX) - Multiple Batteries may be installed Dual batteries for redundancy or even one for each servo (applies to all receivers).
Optima Transceiver (RX) - Battery set up for Nitro/Gas models #1 caution re NiMH.
Optima Transceiver (RX) - Battery set up for Nitro/Gas models #2 caution re NiMH.

RE: Hitec Optic 6 / BH Stuka / flap setup
Alan, appreciate the quick feedback. I will be using all six TX channels, but can use a 7 channel RX. I'm using Assan 2.4 GHz RF module and have both six and seven channel Assan RX's. So it's a simple as just putting an extra pack plugged in to an unused channel? I typically use five cell NIMH packs over 2000 MAH for all RX's. Anything special with charging with two packs connected? Thanks again.

Fred, I can handle the two wings by having the servo output arms all to the outside or all to the inside ... done it before with a Giant Big Stik with flaps, but that one only needed two servos and I had enough radio channels to handle it.

Sure would like to know how you did that Giant Big Stick Setup i'm using the otic 6 radio with it & want to set up the flaps but i'm at a bit of a loss at the moment

RE: Hitec Optic 6 / BH Stuka / flap setup
linkadrip , see attached. I had it backwards. The ailerons are connected using opposite servo sides, the flaps the same side. All connected to the RX via Y adapters. Sorry, got carried away with size!!!!
All photos wing bottoms.

RE: Hitec Optic 6 / BH Stuka / flap setup
Thanks for the pictures 
I used two Y harnesses to connect the servos two the Receiver & setup the Crow function without the use of the ailerons as spoilers. Seems to work Fine but wont really know till i fly the plane But at least now i have control of the flaps & elevator at the same time on the left slider. Hopefully this will make it so it will be able to take off and land in shorter distances.
