    Ok, I just can't get this one narrowed down. I have a savage and I am now on reciever #3. The first reciever (a hitec micro bec) lasted two days. The second (hpi rf-2) and I am just about to put in another hitec. The problem is that everything works fine for about two hours then I lose control for about a second and it picks up again. Soon after that the receiver is dead. I have tested the servos, the transmitter and the crystals. They are fine. Any Ideas? Could one of my servos be putting too much load on the receiver and killing it? I know it takes alot to turn the savage but I figured that 133oz's metal geared servo would have been fine. I am perplexed... By the way I am running 6V via alkalines.

    Try contacting HPI it a question regarding their truck and a stock receiver. If its still under warranty I would expect them to exchange it for you. Good luck!
  3. Try going stock on the batteries

    I agree with danny you may just be overloading the reciever. Also give hpi a ring and see what they say.
  5. Yea its your battery pack.....most 6v battery pack when fully charged will go up as much as 7 Volt and maybe even more. Your receiver can only handle as much as maybe 6.5 volts.....sounds like your frying your receiver......try putting a diode in series with the positive side lead of the battery....the diode will sink 0.7 volts and bring your battery pack voltage down.....or you can go buy a BEC connector with a 6 volt regulator on it.......

    you should be using a 4.8 volt pack Nicads.when they are charged they are under 6V
    6V is too much for the reciver.i am alsmost positive that is the problem.

    alkilines messed up one of my recievers.

    tim, 6 volts is what it needs, what do you think 4 alkis are, 6 volts, your electric cars operate at 6 volts.
    Rock, you have some other problem, like frayed wires causing a short either @ the batt. pack or servos or maybe crossed wiring. Also make sure you wrap the RX in some dence foam to protect it from vibrations. Also try a good 5 cell NiMH pack, it will give you a lot better control of the truck, the alkis don't put out enough amps to give the servos what they need to work properly at full potential.

    i didnyt know you could have to many amps going in i figured it would be crossed wires to does it smell after it gets fried?

    Ok Fellas and you, 6V is exactly what a reciever runs on. That is why you get two torque ratings on a servo. One at 4.8V and one at 6V. I bit the bullet and replaced everything, except the Transmitter. MX3 aint cheap Lol. New Servos, battery box, on/off switch, reciever, crystals, and batteries. Now here is the really dumb part. Same thing happened. About two hours and glitch, glitch, glitch, but I noticed it only glitched when I turned the wheels either direction...Which really #@$% me off more after spending 150$ in electronics. To make long story short the first reciever killed because of vibration (not taped down and board cracked). The second died because of unknown causes. ??? the newest one eats batteries in 2hours. Brand new ones. 2 Hours and time to replace. Boy does that suck. So as far as I can tell, I think, think is the keyword, low batteries killed the second one, and I feel dumb LOL. I had the exact same setup in my Nitro MT and the batteries lasted weeks. I guess it never occurred to me.
