Swash problems?
I have the micro Heli Swash and I just changed out the balls from the stock swash and I am running +13 and -13 with a 10 tooth with low Pitch boost and very hot settings with no trouble at all after loads of stick banging flights. the swash was for a SR same thing as the 300x swash except for the balls.

Great tip 69maversck on the microheli blade SR swash. I had one of these from my old SR and just did as you said, changed the inner balls with the stock 300x ones (inner balls on SR are smaller). Looks great and I can hardly wait to try it out tomorrow! Many thanks mate.

Cheers,
TomC

Just a quick update on the microheli SR swash on a 300x.

After a few hard flights I came to the conclusion that there was no performance advantage over the stock 300x swash. In fact, the heli did not 'feel' quite as solid. I think the problem is that with the stock 300x inner swash balls on the microheli swash, the geometry is not quite as good. The pitch link rods show a bit more inward lean (but do not bind). I probably could have corrected for this by adding a 0.5-1mm washer on each of the inner swash/pitch link balls.

The microheli swash works really well on the SR since it has a very thin profile that lets you get a bit more collective pitch. Also, it's a lot less likely to separate compared to the stock plastic SR swash, and the metal balls do result in a little less slop (although the rest of the SR has heaps of additional slop anyway, lol!).

The stock 300x swash, even though it's got a thicker profile, still allows for up to +/-14 deg collective pitch (anything above +/-13 deg is a waste of time on the 300x imho).

Also, the stock 300x swash bearing is much more substantial and is retained by 3x screws. The microheli swash bearing is press-fit (and probably loctited). It's probably fine for the ~150g lighter SR (~360g flying weight vs ~510g for the 300x).

So, while I think this was a very useful experiment, I've now gone back to the stock 300x swash.

Cheers,
TomC
