Hi Guys,
This is what I want to do.
Thanks for the reference to my plane.
do a RE and have no regrets.

Brand is your choice, I like the YS's and the RF pumpers.

Building a Killer Kaos right now with the same set up

Dave,

I don't know how you feel about it but Park Flyer Plastics, thanks to Paul and Rick, now carries proper Dirty Birdy canopies. Blue Jay makes a good kit I hear but they seem to include the same generic canopy in all their kits. Even the Kaos looks nice with the DB canopy for some $6.

Then again, maybe it's just me who's not a fan of the BJ canopy.

I have an original Bridi that is going on this one.
Yes I dislike the BJ canopy.
It will go in the drawer soon

Just an opinion, but a side mounted 61-65 with a Macs on it will be a great balanced aircraft, with at least 100 mph speed, and hassle free. Tony

Hello,
I just got a hold of the new Great Planes Dirty Birdie ARF. Has anyone put a rear exhaust with a pipe down the side in one? The old wood one I built, it was an easy set up to deal with, never had to take the pipe off like the side exhaust did.

Also looking for a real strong rear exhaust like an OPS or Rossi if anyone has one to part with.

Thanks
Jorge

George,
Here you go!

Buy it. There are not many good .61 RE engines still on the market.

I have a new IRVINE 61 FIRE with a Dykes ring that might be to your liking. Header and pipe available through MACS Products. A very reliable and strong engine. Down on power from a Rossi ABC but not by much. Much lighter than the "fat" Rossi too. You might be suprised. Let me know if you are interested.

Here's a picture of our Dirty Birdy ARF with an OS RF Rear Exhaust. We mounted the pipe down the side as you were suggesting. As you can see it worked out perfect. I'm not sure what header it has because the header came with the engine when I purchased it in the RCUniverse For Sale Ads. The OS had a pump but I could not get it to work so I put a Perry pump in it. Used a Supertigre "S" carb because I could not get the large bore OS carb to idle right. The engine turns 13,500 rpm with or without the pipe. I did not try to shorten the pipe as I like the speed of the DB the way it is now. Very very fast. Running an APC 11 x 7 prop.

If you have any questions I would be glad to try to answer them.
