Does anybody know if I would benefit or lose out by extending the main shaft on my aerohawk.
The only reason I want to do this, and im only talking about 5 mm is because the swash plate can only move so far without hitting the collar at the bottom. I have the facilities at work to easily make a new one but I dont want to make it if it will introduce some unsavoury behavour.

Thanks

Hello

There is no need to make a Swashplate spacer since the SP never moves up or down in the Z axis.....it only moves under servo control and then it just pivots around a central point.

I think you missunderstand me. I dont need a spacer, just more space.

There might be fractionally more weight from a longer shaft, but that's the only issue I see. You will have to readjust/lengthen your swash control links, as well, and stay within the length of the antirotation fork, but other than that, it should work.

Dunno about the benefit... it makes intuitive sense to me that all other things kept the same, hanging the weight of the bird from a longer pendulum against the resistance of the rotors would damp responses, but I doubt that 5mm will make a perceptible difference in that. If you just need a smidgen, you might consider cutting sanding the hub of the main gear and pressing the pinion a bit further onto the motor shaft.

Let us know how it works out -- I like the idea of experimenting!

Based on your pic, the easiest fix might be sanding down what appears to be a wheel collar and just taking up less space...

I think ill take your advice Randii. Ill turn that collar down a bit more.
