Bergen R/C Helicopters > Observer EB with 720mm V-Blades?

Hi all, I was just lifting off when(I think) one of the short ball links just unthreaded(popped from the thread) the heli went to the left, as I was just 1 foot from the ground the only damage was the blades, spindle and some ball links.


I replaced the spindle shaft but I do not have the 800mm blades, I only have the 720mm v-blades any considerations that I have to make?, I plan to test fly it tomorrow as next Monday I have to shoot for a client. My set up weights 20.3 pounds or 9.2 Kilos

If your Observer is geared for the 810's (12 tooth pinion) you cannot run the 720's unless you have a 14 thooth pinion. If you run the smaller blades with the 12 tooth you will over rev the engine in order to creat enough lift.
