As i get further along the build/setup i reach points where i can not find posts here which help.
I went for a 401 and 9650.But i have several Q`s.

.Most posts say not to use the rubber mounts supplied with servo.
If i go this route with the 9650 the holes in the servo are way too
big.
.Why in the set ups i have seen here do people mount the servo with
the lead facing the tail,Then bring the lead forward.Why not face
the lead forward.Is this posible or would this effect electronics
set up.(Sory novice)

Before some of the heavier batteries became used more frequently, the SE's were known to be tail heavy, more often then not. With the 9650's output shaft towards the rear, the weight shifts forward. I am not bothered by having to do some readjustments after loosening the boom for a belt change or servicing, so I used a slightly longer threaded rod to get the servo all the way forward. It also doesn't bother me to add a very small bit of lead to the vertical fin, when a heavier battery is used. The very very minor reduction in pirouette rate, or the speed that the tail direction can be reversed, is not significant to me, with that added weight. I also shorten the 401 and 9650 leads, partly for rearward weight savings, and also neatness.

Microheli makes a cnc mount just for the 9650. Works awsome. If you dont mind spending an extra $14

Boidman.
Is that a 9650 in your picture.Mine as four holes for mounting.your method uses two.The align mounts in the kit seem good,they are metal.But the only way they work for me aleast is to use four screws and the supplied rubber gromets.A post here said that will cause possible problems in gyro performance.

Yes, a 9650. The older mounts were one-holers. I did a mod to get things the way I wanted them. There are/were several other methods to get similar results.

If you use just the rubber grommets without the metal sleeves, I'd wager 117 gold quadroons that there would be no problem-causing motion between the servo and the brackets, iffen youse sqwarsh down real good with the screws. The sleeves are primarily to reduce the squish on grommets, so that the servo gets a little vibration dampening and torque forgiveness. If you buy into that, make sure you use washers on all 4 screws.

I thought I was the only one to drill a hole in the middle, cut the tabs & shorten the leads.
