Sidethrust - 70" Edge 540
 

Hello

I am in the process of assembling a 70" ARTF Edge 540 kit (CM PRO) I have a question about sidethrust - How much does it need?? There is nothing in the instructions (typical asian kit)

I have mounted my ASP 120 AR engine as shown by the illustrations, but when I slip the cowling over, the spinner is about 3mm (1/8") to the right, I slipped a 2m long alluminium tube over the propellor shaft to sheck the alignment of the engine and it appears to have about 3-4 degrees of right side thrust. When I pack the right side of the engine mounts to remove the side thrust the cowling matches up nicely with the spinner..

Do models of this size require sidethrust?? or should I mount it straight?

Please help.

Cheers

2 degrees of right thrust is the normal starting point. could go a little more but unlikely would be less !! ;)
