Futaba rx and heat
I have the 4PK and tried both the 3 and 4 channel rx in both my rc8b and rc8t.
I've had run aways on both cars for no reason other than the rx box gets very hot. The box temped between 140 - 155. Will that cause the rx to freak out and lose signal?
I tried a two diffenent lipo regulators and a new common sense 2s 1500mah lipo.
Any suggestion?
Thanks,
Jody J.

search, but
futaba says not to run lipo even with reg
also
yes they will thermal with heat to prove put it in a box and blow a hair dryer on it, it will shut down at near 160 every time

Jody, we have a 3PK and have had heat issues, no runaways, but just rec. just stopped working, you'll find that the 3PK and 4PK are prone to heat, by this I'm talking about heat from either the motor or outside amb temp. I'm out here in Phx AZ, and one time we ere practicing and it was 113, our rec would shut down just before we finished a tank. We could put the back rec, and we'd get another tank, then same thing. You can do a few things to help, we've drilled holes in the rec tray top for air, mount the rec on its side to help air flow, and put the heat shieldng tape or out side of rec box.
The heat that I'm talking about is from the out side, I'm not sure if you could have a possible servo going bad and pulling more current than normal.
Hope this helps

I run Lipo with regulator with my 4pk and 603fs receivers. I've had the thermal shutdown happen a couple of times in my MP9's. Make sure you have the failsafe set properly. When mine overheat the throttle goes to idle. I ended up mounting the RX to the Lid of the box with D/S tape and a zip tie. Haven't had any issues since. Just changed over to Xray's and I haven't had it happen YET. If your failsafe was set properly, you may have some sort of problem with the regulator. What kind of regulator is it? I run the Orion 10a regulators and have had to repair one due to intermittent cut outs of power going to the RX which will cause a run away unless you have a good return spring on the throttle.

Thanks for the replies guys. I forgot to set the failsafe the first time, so we had a run away. I set the fail safe the 2nd time and it went to idle.
On the RC8B they added a battery box up front, so I will move the receiver and regulator to the front and battery to the back. On the truggy, I will mount the RX on top of the box and see what happens.
I tried three different regulators, 2 commonsense and 1 castle bec.
Thanks!

Really? I mean my 4PK I purchased a couple of months ago appears to be suffering this issue. I had no idea what it was initially. Halfway through the main, I'd lose steering and throttle/brake. I'd take it to the pits and it worked fine...
I had no idea this was the issue! I use a lipo pack and reg. So, i reckon' I can try a NiMh pack....

I bought a 3PM with the FASST 2'4G sistem about 3 years ago and using it with a NiMH pack had that same problem in summer but not in winter.
I drilled the receiver box full of holes (dust got in anyway) and the problem dissapeared.
I have heard of lots of drivers with the same story, but thought it was taken care of in the newer models.
I don't know, but it could also be lipo and new-more potent servos using more current causing also more heating....
