I flying my R50 V2 on Saturday evening and was lucky not to bury it. It was flying very nice when suddenly it was flying not so nice. The best way I can describe it is that it was like the air has turned into thick syrup, I’d bank hard left and after thinking about it for a while the heli would slowly drift left. It was the same with all cyclic commands though collective was fine. Anyway I managed to get it down in one piece and on examination discovered that the two pins in the washout assembly has disappeared leaving the washout linkages hanging loose. There was no link between the Flybar and the main blades thus for the final part of the flight I was flying the heli by the Flybar alone. Anybody know how to keep those pins from falling out?

This happened to me once, the reason is that the part worn out. That is the only time it happened and so far no such problem.

Propabaly replace a new one frequently will solve that problem.

Not having much luck lately !

To be honest, I have never really checked the pins on my own. I think I have read about gluing them in with CA though I wouldn't bet much on it!

You may wish to speak to our Chairman about spares. He's not repairing his R30 and offered the remains for spares. It will save you waiting around for bits to come in?

Unless these fall out regularly and I haven't seen much written here or elsewhere, I think you should have a look for the reason they came out. Maybe that slack bearing on th mainshaft? If you want to check the bearing, leave it on the mainshaft and see if you can tilt the outer race relative to the inside. Any slackness here is not good. I also find the metal shielded bearings do get dirty too so feel for roughness while you are at it.


Part # if you're getting them locally is : 61800.2RSR

Gary is correct. Pull the pins from the headblock, and use thick CA to retain them. Also, the pins that hold the washout links to the washout arms.

Thanks guys, the main shaft does rock a bit so the pins must have vibrated loose. I'm going to fix that before I fly it again.
