Default TREX 450X Questions

Hi all, new to this forum. Have bought a TREX 450X kit (instructions in Taiwanese !) Need to know how to wire up the servos, esc, motor, battery and reciever. The instructions show the tail servo wired to a channel of the reciever while the gyro (align Heading Lock) goes also to another terminal on the Reciever - doesn't sound right to me. Also need to know where to get a battery charger for the supplied Align Li Ion 11.1v / 1900mAh battery (has a 4 pin connector). My hobby shop couln't help. Finally have the supplied Reciever RC-RX6M has a "GEA" connection which i don't understand, also need to know what crystals i should buy for this 72mHz unit (single / dual conversion, and what make) my radio is a Futaba 6XHS on PPM ? Any help greatly appreciated. Thanks. Kev

The connectore on the gyro goes to CH4 on the RX, then the connector from the rudder servo go to the female connector of the gyro. Think of the gyro go between the rudder and the RX. Use the volt meter to check those 4 pin on the stock charger to find the two which are positive and negative, then get a proper connector to match the pack. No need to buy a new charger unless you have many packs. I just bought an Astro Flight 109 and it works great. I believe that Futaba takes dual conversion crystal.
Where is the "GEA" connection you mentioned.
The RX that came with my T-Rex is for JR TX and won't work with my Futaba, so I sent it back to Hongkong.

Are you sure that it's not a battery with a balance contact so that you'll have 1 pin for each cell + negative?
Do you have 2 contacts on the battery?

Check out Aligns pages, they have a charger ment for this, sold on eBay.

I believe Poly Quest uses the same technique/system.

Li-Ion batterys doesn´t work well with T-Rex,it hardly hovers with it,You must have Li-Polys.

You need to purchase a good quality LiPo battery and a good charger for it I use a Thunder Power 11.1 2100Mah battery for mine and the Great Planes Triton Charger and you really can get some flight time out of this battery.
