Live Steam radio control

[stuh256]

Hi I've just converted my Gauge 1 Models 4MT to radio control. At first all seemed well but it has now started breaking servos very quickly! Are there any specific servos to use on live steam that are heat resistant? I notice roundhouse have their servos very close to the boiler! I'm using 2.4Ghz set from an art-tech radio controlled plane!

Hmmm...when you say breaking do you mean burning out?
This could be caused say, if your regulator is closed but the servo has more movement on it. the same applies to valve gear. if when the regulator is closed the servo is making a buzzing sound then this may be your problem. Roundhouse just use standard HiTec servos, nothing fancy

I'm with Sir Haydn on that, try checking the servos aren't trying to move more when then can't i.e. the adjustment isn't right.

Yeah agree totally, I've burnt out a load of servo's on my RC helicopters like that. Hard to hear a buzzing servo when it's about a 100foot above you!
Most modern RC transmiters have a function to adjust the throw of each servo, not always easy to navigate through some of the built in menu functions to find it though.

Thanks everyone!

I'll agree hard to hear buzzing when saftey valve and blower going too! I think by mounting the servo further back i've stopped it pushing all the time so fingers crossed. Have to say i'm loving radio control though much less running round the garden!!

Metal geared servos are available, and Hitec do ones that are as small as 10mm thick.
