RE: Comp-Arf 2.3 with a Brison 3.2
 

Mine came out sligtly nose heavy, but that can easily be fixed during the build. Mine was built for the 3W 50i, but it wasn't enough power in my opinion. The 75 was perfect. Your problem will be the canister fit. I used the canister from the 50, but that's not recommended. It's just too small for a 75cc engine, and the power will suffer from it.
I will check if I can find the pictures from the engine install.

Thanks... I may just run a Pitts to avoid the problem. I thought it might be a little tight for a 75 sized canister. Luckily, we don't have noise restrictions at the field.

Hey Guys, Great thread and it's making me drool LOL Anyway I am thinking of upgrading to the 2.3m from the 2.12m that I have on back order and thinking of selling my da-50. and my question is, what do you guys think of the new DA-85 for powering the 2.3? I know it would probably be overkill power wise but would it balance with it? and will it fit in the cowl without having to hack it up? The reason I'm thinking of the DA-85 is I plan on getting a 2.6 Yak here in the next year and a half or so and from what I've been told the 85 will fly the 2.6m Yak pretty good. So I want a package that I can put into the 2.3 and then transfer to the 2.6m Yak without having to buy another engine ETC ETC....
Thanks,

Shawn

HELLO??????????????????????

The 85 would work on the Yak only if you can keep the weight of everything else down. I haven't weighed mine yet but using a BME 115 and making carbon brackets for everything to be mounted and most would still be hard pressed to get below 24 pounds. Keep in mind that the 85 weighs even more than the 115.

Here is my 2.3 with a 3w85twin..perfect fit in form and function.
