Hi!

I am using the Multi-Servo-Adjustor:
Ord.nr. 1-F1651
http://at.robbe-online.net/rims_at.storefront/en

You can adjust the start- and endpoint of each servo, also the middle point.

Retract servos do not use power at the end of their travel.

Since they cam over they will not drain a battery when not in motion.

Since there are no endpoints to adjust you have to adjust everything mechanicly, but they will not drain your flight battery.

I use a servo reverser "Y" and another "Y" cable to connect all the servos to one channel.

This is for a 3 servo retract setup.

actually, it is more than a std servo. the key is to use the small wheel, not the large ones. the small wheel,(servo arm that is) gives more torque and just about the right amount of throw. just make sure you adjust it so it locks the gear in the down position, dont worry if it doesnt lock themin the up position, thats not a big deal. as for the wheels not going all the way in, they wont anyway as that cheesy bent wire wont let it. this is why i made my own setup. have done this for a few others too.
one retract servo operates all the gears and a std servo workes the doors. doors openonly to let the gear in or out then closes afterwards. a spring keeps it closed while power opens it up. o use microswitches mounted up against the servo wheel on thye retract servo which has nitches in it to tell the doors when to open and close.

as seen in the pics, all the woodwork that comes already glued in the fuselage has to be carefully ripped out. its a horrofying to watch experience and i usually dont do this part with the owners standing there cuz they freak out at the noise and the mess.

Standard servos work with tweeking

I have been using the MG Hitech Hi-Torque Servos (3 of them) with the right servo horn locations and tweeking I got them to work fine, I found the retract servos to be awfully big in that set up and I went back to the standard ones. No problems yet!
