The only way to do this accurately is to make a setup
board.
It can be made from anything, as long as it is flat. A
simple piece of plywood with a slot cut in it will do.
It should be at least 8x24 inches. The slot should be
centered at on end and be about 1/2x4 inches.
Steering servo
There are a few choices when it comes to steering setup.
The traditional way is to mount the servo in the radio box
and use pull-pull cables.
The holes in the radio box are made for a steering arm
that measures 2-1/8 inch from hole to hole.
We strongly recommend that you use an arm of this size.
If you don't, you will have to move the holes in the
bulkhead.
The other method is to use a waterproof servo near the
transom.
This is the method we used.
We mounted a standard sized servo on one of our 3711
mounts.
Use a 4-40 pushrod with solder clevis and Sullivan 4-40
ball link (Zipp 3574) for adjustment.
Be sure to keep the linkage inside the center section. It
will hit the cowl if you don’t.
If you look close, you will see that we added a 1/8 ply
spacer behind the servo mount.
Water Cooling
For nitro, water cooling is contained to the engine.
For electric, you need to cool the motor and ESC.
We run a couple of brass tubes near the bottom corners of
the transom.
Use 5/32 tubes about 1-1/2 inches long.
