The only problem with twins and 3d is you have to add two headers and two pipes or cans or a y header and one large pipe or can. This is the biggest weight penalty, not just the engine

It does run nice and smooth though. Just not as snappy as jeffs anymore

Re: The never ending engine thread, East-West

My first 3DHS Yak was a used package with a DA70. Would have taken serious tail weight to get the CG back to where I wanted it for 3D. Probably an awesome package for carving nice lines and more IMAC style.

And the 70 in the 3DHS 104" didn't work out.

They need to start making some 33% airframes for the 70cc class IMO.

Yes they desperately do....but I have twin smooth pipes going in my new Yak. Going to try some rocket soaring and get up with Lorne and Dales gliders..

Ya Jack!!! I had the 33% H9 Suhkoi in the Blue/silver wavy-redbull-sorta scheme with a 3W80xi/canister and DA85/canister and it was such a nice combo. I bet the 70-twins would be whicked in that size.

But they also will have to make wider tunnels for those that don't want to make a 2-into-1 header.

Yes, the wye header will only work properly used on a can. (Unless Lorne gets some hype 70cc pipes) That's all it did on my RE2 is make it a canister.

The RedBull was a wicked scheme back then and still is. Love Bradley' Ultimate and Jack Marcottes scheme as well.

Just not as snappy as jeffs anymore[/QUOTE]

That is because I am running half a paint shaker with a hype pipe and a tune from the man himself. Not to mention mine is lighter because it is blue and white. Lol.


I bet my airframe will have a shorter life.

Maybe your thumb is just faster. Is that all you and lorne do all day is practice throttle pumping?
