So Tim !
What makes it a Super Mac ?
I have a 72 Mac on my B8M and I would like more hp. How do I convert a 72 to 90 or even 100 , I think a super Mac is 100 hp. isn't it ?

[Timchick]

A super Mac is a 90 hp Mac with a custom intake manifold with dual carbs. Gary's has 2 Holley 1920 carbs on his Mac. My 72 Mac engine has plenty of power for me. I weigh 155 lbs.

Your half the Man I am . Well !!!!!!! I weigh twice as much as you do .
155 lbs. that must be nice . And were can I get good mac manuals ?

[Aviomania]

That is a really impressive power to weight ratio, as well as grate flying.

I felt that Garry’s flight demo at Mentone was the highlight of the Mentone convention. Wish some one would have videoed it.

I can see why you want to add more power. The ideal gyro for you would be a Mad Max with a Soob engine.

Try looking on ebay for a manual. I see them listed on there every now and then.

Tom Milton suggested that I just loose weight . That may be cheaper .

Great videos Tim.

Does anyone know what blades he's flying. I noticed they don't cone much.

I'm guessing Rotordynes.

Gary has been flying a loooong time but his takeoffs are in the 'Don't try this at home, kids!' category. No matter how many times I see him leave the ground I always hold my breath until he is at altitude. His initial climb out angle, that you really can't appreciate in Tim's documentaries, is scary!

McCutchen Sky Wheels. Theu aren't being produced anymore. The machine is very light.
