Thanks for your advice everyone, helps a lot. Some good guidelines to work with. Definitely been changing tx batteries too often, and I really don't think I'm using rx batteries to full potential, I normally only get out for an hour or two at a time.... I reckon I'm going to start running the rx battery down between charges to improve lifespan. I had a runaway early on when I first got into rc. The cause, I think, was using a 4 AA holder for the rx end and that seemed to run down really quickly, or I just pushed it too far in my inexperience/excitement. I've been paranoid ever since! Got all this great gear now and I want to get the best from it ? BB

Thanks Tug. I thought memory effect might be an issue. The new radio set gives a lot more visibility of battery condition so want to make the most of it. Would like to run them as low as safely possible before replacing or recharging

Hi all. Recently got a shiny new radio system which comes with lcd screen and telemetry features including read outs for both tx and rx battery voltage. The transmitter runs off 4 standard Duracell AA batteries and the receiver on my nitro rc runs off a hump pack. Not one for tempting fate, and not wanting a runaway car, I don't want to squeeze all the juice out of either end of the system to figure out when things stop working. Having said that, I charge or change my batteries after every session and I suspect it isn't always necessary so I reckon I could let them run down a bit more than I do. Will either battery run down to zero voltage before it stops being usable, or is it the case that once they drop below 6 they're done? Or is it somewhere in between? I have the option to set low voltage alarms so it would be good to know where to set them. Cheers BB

Thanks spannermonkey, appreciate the reply. Sounds like I should be able to get by without then. Cheers BB

Hi All I've been looking at buying a piston stopper to use during a strip down and re-build of my standard 1/10 nitro truggy. No problems there, no shortage of choices. I've recently got a Hyper SS mach star .28 which came with turbo glow plugs and I've stuck with those because that's what I got with it. Most piston stoppers I've seen are careful to say that they should only be used with standard plugs. I've not yet managed to find a stopper for use with motors that use turbo plugs. What are my options for a turbo engine? Is the advice correct, or can I use a standard stopper with the turbo engine. Don't want to cause any damage. Was hoping to buy a tool once, but if I need two tools it's no drama, they're not expensive. Cheers BelfastBert

Thanks for the replies, appreciate your input. Looking into buying a hump pack. Checked with the manufacturer who was very helpful. Using 2.4 ghz and failsafe is built in already. So, if batteries aren't the problem, it could be a bigger problem. I was also filling up with the motor running, just this one time, and they said it would cause problems as pressure would be lost to the head of the tank and cause the engine to lean out, increasing revs etc. so I'll stop doing that. This would concur with the air leak suggestion, live and learn. Thanks again.

Hi everyone New to nitro cars and rc in general, got bought one as a gift for Christmas. Got it running and gradually going through the breaking in process. Having a great time with it.... Until something happened! Just wanted to check if I'm working on the right lines about how to resolve the problem. Was running the car around a car park the other day, first time I was giving it a bit more throttle. All of a sudden, the car went mental, spinning uncontrollably in a tight donut. Couldn't stop it it, literally had to pick the car up and pinch the fuel line to kill the ignition. Fired it up again a few mins later, controlled fine for a few mins until it was heading back towards me, then it went crazy again and I was just lucky that it ran into long grass so I could grab it. Is this just the batteries failing? If so, I plan to buy a failsafe so hopefully problem solved. Can I just buy any failsafe or do I have to look for a specific brand? The ones I've seen are brand names which are different from my car. The car park isn't massive so I don't think I went out of range. By this point the batteries have had an hour and a half, just using standard AAs from the shop where the car was bought. Up to this point I'd been running for a tank, turning off and letting the car cool for 10 mins before firing up again. This time I filled up with the car going and carried on for another tank. I'm on about 7 tanks now, gradually leaning the engine a bit at a time, still plenty of smoke coming from exhaust so don't think Ive gone too far with it, however I was concerned that chaining two tanks might have caused a heat problem and may be another reason for the problem. Is this a possibility? Thanks for your help everyone!
