Servo/Receiver set up 4 an Offer I could not refuse
Dumb(?) question on wrong site. Was given on offer I just could not refuse this past weekend. A neighbor's love life fell like a lead ballon when his live in girlfriend of 5 months decided to go back to her old boyfriend of 15 years, 2 months after he rented to buy a moble home. He moved back North Saturday night, vowing to never return. He gave away Free, all of the furniture he bought to other neighbors. To me, he gave me a New, never flown or started Scale Pilot RC plane with a 73 inch wing span and 62 inch body, with 6 Hi-Tech servos, DLS-30cc gas engine, extra wings & bag, Pontoons, Plus a Spektum DX6i transmitter and receiver, along with 3 large storage bins full of RC plane stuff. Everything is installed except the receiver. As the Pilot uses 6 servos, 2 for the Ailerons, 2 for the Elevators and 1 each for the Throttle and Rudder, I'm at a loss of how to plug in the servos. Do I use Y-adaptors for both the Aileron and Elevator Servos to their respective slots in the receiver??? I'm not about to learn how to fly it as a slug has better Eye, Hand coordination than I do and am thinking of selling it once I get everything checked out.

I would use separate channels for the ail. and a y harness for the ele.

Depends on what Transmitter you have, but I have a couple airplanes set up how you describe.
Mine are set up like so: Throttle into THR Rudder into RUDD Right Elev into ELE Left Elev into AUX2 Right Aileron into AIL Left AiIeron into AUX1 On my JR X9303, I set the aircraft type to Aerobatic (Airplane) with a wing type of "V-Tail". That mixes the aileron servos together. I use servo match to tie the elevator servos together (you can also use a 1:1 mix between ELE and AUX2 to do the same thing) I then use channel reversing to get everything moving in the right direction and endpoints to get the throws to where I want them. I dial in neutral positions as close as I can mechanically and then use subtrim (usually I need very little, if any at all) to get it perfect. Easy way to ID servos if the ends aren't labeled. Fire up your Tx and Rx and plug on servo at a time into the throttle channel. Move the stick and see which control surface moves. Label the servo wire. Repeat for the others. Good luck!

Congrats on your plane. 30cc gassers are the best bang for your buck in airplanes.
I don't believe the dx6i has the ability to match to servos like the 9303. I would strongly recommend a servo equaliser such as a jr matchbox or a smartfly equaliser II or 3d. This will allow you set both elevator servos so that they center properly and have equal travel at full travel. If you don't you may find the plane has a tendency to snap roll when you pull back on the elevator.

Aileron:
Use 2 channels an enable the "flaperon" or "aileron differential" mix. You will have the ability to dial in differential to compensate for roll/yaw coupling, and could experiment with flap and airbrake mixing if desired. Elevator: Also use 2 channels if at all possible.A simple Y-harness wont work for the elevators, since thy are typically mounted mirror image on each side of the fuselage, one of them will need to be reversed. Not to mention that no matter how perfect your mechanicals are you often need tine tuning of the centers and end points to match them perfectly. If a single hcannel is the only option you will need something like the mentioned matchbox or programmable servos to get the directions and centers matched. Simple way is to do it in the radio with two channels as mentioned. I'm not an expert on spectrum, but the mix you want for the dual elevators is usually 'ailevator' not v-tail. Just leave the aileron component at zero. One final thought, if Hitec's are digital you also have the option of using the hitec servo programmer to set the neutrals and end points even when using 2 radio channels, thus avoiding the need to set different sub trims and differential throw in the radio.
