As for an airplane for the .074, any one of the classic .15 size airplanes may work, such as Ringmaster Jr, Flite Streak Jr, Jr. Nobler, SIG Akromaster, and the Shark .15. Just watch the weight and be careful on finish. I've been eyeing the Acromaster for the .061 and also the Shark .15. Might have to go to 1/4" balsa for the fuselage or the currently popular built up profile fuselage. Lots of possibilites in the old magazines also. Check out the new Flying Models plan we site.

Hi Dan, I gave this a bit of thought before I answered your post concerning the Sig Akromaster and a 1cc engine.
A couple of years ago, I kit bashed an Akromaster, building it for a 1.0cc diesel engine. I shortened the nose
to accommodate the smaller fuel tank required for diesel runs. I replaced the fin and stab wood, with
stronger and lighter qtr. grained balsa. I doped and covered the wings with light weight "Clear" Micafilm.
Come to think of it, I may have replaced a lot of the wing wood also.
Any way, my Akromaster ready to fly sans fuel, powered by an MP-Jet 1.0cc TBR diesel weighs 12.1 ozs.
I quit playing with it after about six flights. It fly's very well on 44' X .008" lines. Whenever I fly it again, I will
cut the prop diameter to 6.8" and up the pitch to 4.5"s.
The bottom line is that with careful construction, being mindful of power and wing loading; the Norvel .074
should work very well in the Sig Akromaster. You do not have to go to extremes with fuselage construction.
I used the stock fuselage blank in my 12.1oz Akromaster; 1/4" balsa is completely unnecessary and a bit
flimsy for the Norvel .074. Best if luck;
Tony
