Default Need Radio Help ASAP Pleaseeeee.

I have both an old Futaba Radio and a brand new POS from towwer hobbies. When I ran the car last year before engine died I had no probs with radio. Now I have installed new radio and engine evry thing runs fine untill I get more than 10 feet away then I lose all control of the truck.
I have changed recievers and get the same prob. I have not changed out trans yet because my Futaba's battery holder is FUBARED. Please help. I have also tried differebt crystals.

Hey check your transmitter battery power, and make sure the transmitter's antenna is screwed in all the way.

Thumbs down Hey Vortex

Just checked battery voltage at transmitter = 12.5 good there, took apart transmitter and checked antenna good connection. I fixed my futaba transmitter and both are doing same thing on two sets of crystals. re-routed the reciever antenna well away from servo wires and still have the problem.
Think maybe for some reason I need more than 6 volts to the reciever, never had more than 6 before?

Hmmm...

Well, I know for a fact the receiver doesn't need more than 6V, the battery box (for non BEC receivers) had 4 batteries in it. Maybe your BEC Circuitry is slightly damaged? Try 'eliminating' the Battery Eliminator Circuitry as a test. Who knows?

Seems like a longshot, but maybe something has moved into your area that is creating a lot of interference. Try some other radio control device and see if that performs similarly.

Default Hey Vortex

There is something i have not tried yet but was reading an article on radio's. I checked and I had my crystals backwards tx in the rx and vise versa, I will try this later and see if it makes a difference.

You need to get a 4 AA battery pack and plug it straight into the reciever. Thats all very simple, will not be any better than the BEC except that your battery will last a little longer than usual.

Default Vortex.

No luck on the crystal switch, Did not help at all. Guess next time I will buy a better radio than the tower hobbies brand If I could just find the antenna to my Futaba I think I would be ok.

If u have a three channel receiver you can plug the batt pack to the third channel(bypassing the bec) and it will give max volts/amps to the servos
