I'm putting one of these gyros on a 450 sized heli. I had previously used a 770 3D on this and I had to mount with the wires pointing forward (or backward I suppose) or it had terrible wag. The directions for the 370 are similar, but I'm curious if anyone here had mounted one with the wires exiting to the side with success? I'm trying to keep the wiring on this bird clean and this would be a much better way to mount it.

As long as the gyro is flat to the axis its controlling, in this case yaw, it doesn't know or care which way the wires are pointing. That goes for all gyros.

I would have agreed with you up until my 770. I had it flat with the wires exiting to the left and when you picked it up it had a fast wag. I turned it 90 degrees on it's base to have the wires pointing towards the mainshaft and it was locked. I had never seen a gyro do that before. I moved it purely on a whim and it went from unflyable to silky smooth; hence my concern with the 370. I'd just do a test, but I don't want to run the wires nicely and have to tear it down to redo the wiring if it does the same thing the 770 did.

Was my experience with the 770 unique? I always just assumed from my observation that it couldn't be mounted with the wires pointing anywhere but in line with the frames.

As I said it doesn't matter, I've flown and helped set up the 770 and they aren't sensitive to which direction they are facing. After all how could they fly sideways or backwards?

What may have happened is there was a problem with the mounting. This could have been tension on the wires transmitting vibration to the gyro or something of that sort.

Cool, thanks. I would believe vibrations being transmitted... it makes the most sense... I always thought it was weird, but I almost didn't bring the heli back after 2 test pops had severe wagging, so I wasn't in a hurry to try it again. I'll mount it to the side and make sure I give it some slack. Thanks!
