Well I am getting a used Brison 2.0 engine and was wondering where to start with prop size on this engine ? What kind of rpm will this engine turn ?

I am assuming that the engine was manufactured after Brison took over A&M. The engine looks identical to a current Brison engine and the ignition control box has a Brison Aircraft sticker on it Any good pros or cons for this engine ?

Thanks in Advance

I am running a 3W-35 (2.1 CI) with a old style Zinger 18 x 10 @ 6600-6700 RPM. I think this is a bit much prop. I plan to try a Menz Standard 18 x 8. This should get me aroud 7000.

Hope this helps.

Superfast,
I bet what you have is a A&M 2.0 built by Gary after her bought the assets of A&M Aircraft from the bank. There were allot of existing stocks of engines and engine parts that only needed a technician to assemble them. Gary retained two such people from the old company and together they painstakeingly hand assembled and ran engines. The 2.0 is one of the best engines of its class ever produced by anybody. And the claim to say that is simple it ran and ran and ran.....was not the most powerful or the prettiest but it was like an old castiron straight six auto engine there wasnt anything you could do to other than crash it to make it not run. Some people might poo poo that but these engines that came into the shop where the owners claimed were garbage only needed papa Gary to apply some TLC and they sat up and barked like a big dog.

The 2.0 was the origianal idea of Al Willart of Al and Marylin Aircraft ( ie...A&M Aircraft) Al's original idea was to make all the engines like the 2.0. from the smallest to the biggest and the twins ect... but fate was not to be with them and the rest is history.

Sitting here reading the original literature from AM/Brison it says the 2.0 = 32.7cc wgt 2.75 lbs thrust 16lbs props 18x8, 18x6-10, 18x10. Al and Gary both run down to the hobby shop and buy what ever is on hand (usually zinger or TF) and use that just like you or I would if we had the motor. All the 2.0's should turn 7100 -7200 RPM on an 18x8 or 18x6-10 Zinger prop.

The ignition I would not use. Call Bill Carpenter up and buy a CH ignition for a TCSA AM 2.0 Make sure you say AM 2.0 cause it makes a difference.

Never worry about parts as long as Brison has 2.4 you will always have cases. The 2.0 and 2.4 share almost all the same parts.

Well you got a keeper.

Wow a reply after almost a year ! Well I ended up finding the the 2.0 really likes a Mejzlik 19x8 Carbon prop. I had been running an 18 x 8 Zinger Pro but came across the carbon and gave it a try. The Carbon prop really woke the engine up, it flew with alot more authority. I have to admit you are right about the engine, it runs like a top. I haven't had much troubles at all. I did get a new CH Ignition box from Bill. I gave the original a try but it caused alot of interference during the ground test runs.

Yeah sorry about that!

Long time modeler just started reading and answering RCU. But glad you found the right prop. I taught one of my good friends how to fly on a Robinhood 80 that we built. Originally we had the stock engine on it a Maloney 125 (Baloney 125 more like it) When I was working at Brison I sold the 2.0 to my buddy and replaced the engine on the hood !

Wow what a difference, and your right about the ignition (Gary tried to make an ignition to compete with CH but could never get the quality he needed) But my buddy had enough confidence with the 2.0 that I got him to fly at the local IMAA events for the first time. We had a blast flying his bigger stuff and he would fly his Robinhood right along with the others.

Well enjoy !

Superfast,
What kind of numbers do you get with the 19x8 prop.
