Just picked up one of the norvels (big mig .061) So I know some of you guys have one of these. What kits have you found that match up well to this engine? BTW I'll be flying sport-stunt with it not combat.

The Big Mig 061 is a powerful engine. Too bad that it has some design features not compatable with our 1/2-A stunters.

Fer instance, I built a PINTO 1/2-A. The angled N.V. assembly on the Big Mig could not be turned around for inverted installation. i.e. the N.V., if turned around to place the fuel tubing at the outside of the circle made the needle hit the prop! (even small fingers would have trouble). Second: the stock muffler is too close to the cylinder for any sort of cowling.

My answer: Mount the engine upright, and build an exhaust extension from aluminum tubing (but no muffler).

Brodak 1/2A Pathfinder. This is a large, full featured 1/2A profile, that flies very well with the Norvel .061.

Well, can't pass up a chance like this, can I now? Look at my offerings, all have been flown with (some designed around) the Bigmig .061.

As Dr. Spark said, these are extremely powerful engines, and are just too powerful for normal sized 1/2A planes. I put one on a 1/2A homemade Skyray that had 1 inch added to each wing. It flew so fast, that the wings actually fluttered in flight. Fun to watch, but not very practical. I also have a Norvel .049, and by comparison, I would say the .061 is almost twice as powerful --- it also has about twice the fuel consumption!

Why does it have to fly fast? Just use a bigger, lower pitched prop. I don't see how it can "overpower" the plane unless it is some wimpy size thing and the prop gets to be half the size of the wing span. Control the speed with rpm and pitch. Add a little more diameter to load and slow the engine, and then reduce the pitch accordingly.

I just slowed it down with a Golden Bee.

Try 42 foot .012 lines and a 6x3 prop. Guaranteed slowdown.

I'm waiting for Brodak's Baby Clown ARF to use mine.

Regards,

I saw a set of plans drawn by Ron B. of a Spitfire that calls for a Norvel .061.

I have one in the Dick Sarpolus designed Mustang and I fly it on 40ft .008" lines .It is a great combo.I have also flown Sig Skyrays with them teaching youth to fly and had great success with them.Watch what you run for a prop and run it rich and you will have no problem with the little Skyray.

Brodak Baby Flite Streak. The plane is awesome with it. 42' lines.
