Are there any diferences between the original RCM Advanced Trainer:

And the updated one:

I want to build one and use a ST45 for power, is that enough? Is there a 40 sized variant I couldn't find on the RCM listings? Or should I simply clip one rib bay off each end to make it 45 worthy?
Also, how did the Great Plane Trainer 40 and 60 designs vary from the original Joe Bridi design? Does anybody have a copy of the GP Trainer 40 plans they are willing to copy or scan and email? PM me with details if you want to keep it quiet.

Mark, I've got both plans and the MKII is set-up with bolt-on wing and a couple extra ply spars (one main and a thin trailing edge spar) The plans show a K&B .61, We used to use HB .61 PDP's and they would really haul the mail. You're ST45 would fly it no problem.
The Bridi designs used a full length elevator while the GP version was re-designed with a split-elevator and full length rudder. Some say the latter worked better. I always used the full length "Bridi" elevator.
I've got the plans in Tif and PDF as well as the construction article. I had the guy at work that runs the wire EDM machine to cut out stainless steel templates for all the ribs/bulk-heads,etc. It builds pretty quick and is a solid airframe that will last many years.
Go for it! you'll like it.
