Hi this is a idea i put into action a few days ago and its come out really well. Its parts from a trex helicopter GWS geared motor drive old canera mount and 2 servos (HS-65MG) Hextronic HXT 500.
I ill include pics to show how it goes together. Its pretty easy to make. cheap too. most expensive part was the HS 65-MG servo. but i have a few spare so didnt cost me anything. But first pic is the finished item. list of pics are as follows
1) Fully built and working
2) Parts required
3) Gear from GWS slow stick brushed motor mount
4) Shift from GWS Slow stick brushed motor mount
5) Bearing blocks cut from a Trex 450 helicopter. From shaft for tail belt
6)Close up of gear from Hitec servo on shaft
7)HS65-MG servo glued to trex tail drive bearing mounts
This is very simple to do and make. I simple found the parts needed in my spares box. I first found the 2 gears that fitted together (hs325hb) and gws slowstick motor gear. Then drilled the gear to fit onto the ss idle shaft (3mm).
Then cut the rear bearing block from the foz of a Trex 450 (they use a 3mm inside diameter so fit spot on),then slipped the shaft into the bearings and set servo gear onto the splined part of shaft.
Once that is fitted into the bearings i glued the HS65 onto 3mm lite-ply. then flatted one side of the bearings and also glued that to the bearing block.
Thats pretty much it really. I found that the two geared messed spot and and turned 180 degrees both directs. Actually they move about 190 degrees so reduced it on the Travel adjust on my transmitter.
Then i found a old mini wireless camera mount and with the threaded part of the shaft i drilled a 3mm hold in the dead centre and bolted that to the wireless camera mount.
Then i had to cut the shaft down so i could put a servo in the bottom of the camera mount and glued it with epoxy,the superglued a servo arm to one side of the mount and drilled a hole on the opposite side. This then swings freely. After connecting up the servo i found it all works well and without fault or binding.
Also make sure u drill both the servo gear and the motor gear in dead centre or u will find it either does not engage with the servo gear or it binds and u knacker the servo.
Good luck with it and please contact me if u need any help or advice. Austin.
