Hi Bill,
We have a new one, MKII,  in the club.
"IF" we ever get around to it we intend to compare it, via flying it, in a Brodak Baby Clown that now has a Norvel .061.
Will let you know the results.

Caution: Not sure when it will be done as Retirees never seem to have enough time to do the things they want to do. You are destined to discover this in your retirement!
 

Jim,
Agree, and I still get up before 6am.
Have seen too many that retire, sleep in every day, loaf around and then pass away before their time.
Have "another" great day!

My mind works 24-7 trying to figure out how to fix the latest screwup on the plane I am building or finishing.

          I currently am using a Brodak .061. I took the advice and drilled out the threads in the head to install a head button glow plug from a ASP.061. This gave me a bit of rpm boost and easier starts as well. I found it starts much easier without the muffler. The instructions call for a low nitro fuel 10 % and not to go too high with the nitro. I found it works using 35%. Its hard to draw a comparison between a Norvel and a Brodak. These are entirely two different engines. The Norvel Big Mig makes a lot of power and the AME makes considerably more. The instructions claim 12,000-17,000, but it doesn't state on which particular prop. Norvel engines are a bit higher than this usually in the 19-20+ k spectrum but typically using small low pitched props. I'm using a white 5x4 Tornado on mine but I don't have rpm's to date. If you have large hands like myself I would insist that you extend the needle somehow. I've used as large as a 6x4 but the instructions claim 7x3 is the largest. In my honest opinion, I'd keep the props on the smaller side just to avoid heat. Now that i've learned the starting sequence of this motor it starts pretty quick. I struggled for quite some time due to the constant flooding I was giving it because of over choking. I watch the fuel line now until the fuel is very near or just to the needle and give it a small squirt in the venturi and a few flips. This engine shouldn't be confused with a hot rod but a real mild mannered engine. Mine hasn't skipped a beat in the outside of a square or the top of a overhead eight very steady. I'm considering trying the muffler once again using a pressure tap for muffler pressure. My tank on this plane is glued in place using small balsa blocks so canting the rear of the tank isn't an option here. I was wondering if muffler pressure would cure this. The plane I'm using is pretty much the same size a the Brodak Baby Clown. I would say mine is on the heavy side due to considerable repairs and heavy balsa.   Ken Cook

Sho' do, brudder!
