I know this has been posted before here...but not a whole lot
of info on how they fly . I want to put a RAM 500x in one.
Whats the speed envelope with this setup?

Thanks

mach1- Not sure myself yet? I will be installing a PST 600 very soon in my MB339. Tam has said his one flies great at 21 lb with the RAM500 + smoke, and is quite quick.... Slow end should be very good if AUW is kept down. It has a ton of wing area + big flaps, so I am not worried about landings. I hope to fly it off grass as well. : )

And here is my chosen paint scheme- RAAF Roulettes for my ARF MB339 although the Roulettes flew an earlier MB 326, I like the colours and it will do me!!

Marty,
Take off weight 21 lb with 25oz smoke and 78oz of fuel.
My assemble kit little heavier than stock. You noticed I reinforce main formers, stabs, fins, landing gear block.

I have a kit built that I intend on flying within the week. It has a simjet 1200 in it. with 60 oz of fuel. Empty it is 15.5 pounds. I think it will be perfect with this size of turbine. I will let you all know how it does.
