This is the project I've always wanted to do. R/C... dual aileron servos
and elevator. It seems to me there has to be some folks who have done it
and Im hoping someone can point me to more information. I'm hoping to
upscale it 2.5x so I can use 2.6" dia kraft tubes for the airframe. Also it
would seem that I could keep weight down by using coroplast for the wing,
though it wont so nice. Im hoping I can draw off of someone else experience
but any info/suggestions will appreciated.

ps My understanding is that boost-gliders , legally, can only use mid power
motors. Is this true ?

I don't think so...look for the 'X-30 project, they flew an RC 'boost
glider' an a Hypertek M! That sure aint no mid-power motor! Very nice flight
if you can find the video.

Years ago a NIRA member upsacled one of these and flew it in up to J motors
IIRC. I can't recall if it was RC or just free flight like the original. I
know I saw it fly at least once.

Hardly. Competition classes are limited to G motors only because NAR
competition is limited to G motors. But plenty of BGs have been built that
are true HPR. AstronMike used to be active here, and did all sorts of stuff
like that.
