Keith,<br>

I have been very happy with 2 digital programmable MCV2 micro servos mounted
on their sides inside the stab of my Viper 202. I originally had the MCV2
superflat (11 mm) servos which worked fine, but I liked the quicker speed
and power of the micros, and they were still only about 1 oz each. I like
the short positive nearly frictionless connection to each elevator half (MK
ball bearing clevis). They have held up very well and I had no problem matching
the throws. I didn't even use the programming feature, I just plugged each
servo into a different channel and mechanically matched them as close as possible.
One possible advantage could be that you could have each servo work independently
with ailerons if you wanted to. I do that on my fun fly plane and it works
great (I am thinking for a multi-purpose AA plane).<br>
I mount the servos on their sides to a light ply and balsa sandwiched rectangular
plate. I use the outer balsa layer to exactly match the curve of the airfoil.
I then cut a hollow plywood rectangle that will support the servo in the
stab. The width of the plywood rectangle (donut) is such that 1/2 will be
under the balsa stab sheeting and 1/2 is used to support the servo plate,
the center is cut out for the servo. I then use a router to create a box for
the servo and mounting plate into the foam core before sheeting in the stab.
Glue in the plywood rectangle and sheet the stab normally. I then drill a
hole in each corner to attach the servo plate. I later added an access hatch
in the bottom of the fuselage to help fish the servo wires and extensions.
Send me a message and I will e-mail pictures if you like.<br>

This is exactly what I had initially considered on my Aries so my removable
stab would be easier to remove. Essentially they would be like small main
wings.
However all the feedback that I received seemed to indicate that this was a
bad idea due to extra weight, possible differences in throw over time, etc.
I'd like to hear pros and cons from others that use used this technique.
Thanks,
