Pro785 power valves snapping/breaking
Does anyone know why they break? When going out this year for the first time, I noticed 1 valve was stuck in the up position.
That's not right. Took off the valve and the valve was snapped in half. The Blade too. Checked the other 2 and 1 had part of the side stems broke off. Why????????
Is it just junk pot metal ? Fatigue? All they do is go up and down by a servo motor.
Anyone ever snap or break 1 off? I keep the stem and blades clean too. Just wondering what's up
Id like to find some steel ones. I think its a bad design where the stem attaches to the blade. Too thin for the vibrations.

I've only seen one break in 10years of having Pro's. I have a few take off's sitting around if you need them...

Thank you sir! I need 2 original ones. That would get the other motor almost back together. Need 2 piston n rings too if anyone has any. Used is ok as long as they are good still. I'll get new rings for them.shoot me a pm.:
That's intetesting that you have only seen 1 in all the racing you've done . Really have no idea why mine snapped. Maybe just fatigue..
It has weiscos in it.

Are you sure you had them installed correctly? I think this may be the problem most of the time.
