12 x 5 on it , figure its the max itll swing , have to lookn see if ive a 12 x 4 .
Pulled the 2 kg Spitfire effortlessly on a 10 x 4 3 blade . test for windy prop .
Must throw that muffler picture on , this is the same weight   G 51 flew it
easilly , theres always the K&B 7.5 if this dosnt work , already a few flights
on it with that , sans muffler . This can cook the tank so it goes lean .
figure I will lag the header internally.

Matt, you are doing beautiful work.

Matt;

If you need to bend the pipe OUT, it is fairly easy to do.

Need:
Propain (map gas prefered) torch
fine sand for stuffing the pipe (can get it fomr Lowes/Hone depot)
Pair of heavy gloves for heat (naturally of course)
vice mounted to a bench
long 3/8 or 1/2 drive socket that fits over the header tube (and also a nice longish extension)

stuff the pipe with the sand and tape off the motor side so it wont fall out
chuck the motor side in a vise securely
heat up the pipe real good until it just starts to turn a shade of orange/reddish where you need it bent
slip the socket with the extension over the pipe and slowly and carefully start bending it out (while keeping the flame
moving over the pipe area)
when you get where you want it, remove the heat and socket and let it air cool.

the key here is take your time and keep the flame moving

Or you can call MACS products out in CA andask them to make you one to order.
