In my opinion, the quality of these valves is questionable. I'm probably very unlucky but I bought 2 units and had 2 valves dead on arrival. Todd took care of both but still, this was not the best experience. Further, when they work, there are still a few issues:<div>
</div><div>1) The valve purges the air from the retracts when turned off. With some retracts, it means the retract will occasionally collapse while pushing the plane around with the rx off</div><div>2) I have seen occasional (pretty rare) occurrence of the gear retracting while turning the receiver on. This broke some gear doors on one occasion. And yes, the failsafe was setup properly.</div><div>3) The smooth brake function uses too much air and is not as good as a mechanical smooth stop unit.</div><div>
</div><div>Because of 2 and 3, I use a manual valve on the gear down line.to make sure there is some air when I turn the rx off / on.  That's a pain.</div><div>
</div><div>For these reasons, I have decided to go back to a traditional setup.</div><div>
