Looks very stable and smooth.

It really is Rusty! it flies LIGHT! i think the squares add up to 1360??(hazz-correct me if i am wrong)..pretty darn close to 30% wing area and only but half the weight

fun plane!

Andy's right about it flying light...the wings are 1,383 sq. in. but what's 23 sq. in. among friends
The cool thing to me is it flys like a foamy w/o the disadvantages of a flat wing PLUS it can handle wind really well. Most are coming in at 9lbs to 9lbs 1 oz. There's one being done now that will be in the 8.25lb range and will fly with a OS 120AX (takes some mods to balance it though).

Thats a whole lot of wing area. No wonder it flys like foam, how does it compare to a mojo/moass 60/65?

to me, it just flies like a HUGE moass 60 ....a bit more agressive and floaty than a 65 (the EE is lighter with more squares, and the surfaces are all larger than that of a 65 too.) but power to weight stomps any other fuel burning plane i have ever owned, and thats some fun right there LOL!

Do you think you would get the same sort of performance on a small gasser (26cc)? Not a huge glow fan since I started flying gas. I hate glow goo.

Rusty, I think the Evo 26GX or Roto 25 V (both beam mounted) would be great for this plane. They are heavier than the Saitos but will also carry ~1/2 the fuel so it should roughly balance out weight wise on the nose. The foam proto type at ~9.+lbs flew with a Saito 125 but was very anemic coming out of hover (i.e. no reserve power). That tells me that the 25-26cc gassers should be a great fit. In fact, the Evo 26 is going on a friends locally later this spring and I think I'll build one with it as well.

Brian you did a killer job on this plane!!!!!

BTW, the wheelpants make it right. Don't let anyone build one without wheelpants!!!!!!

[Sotos]

Regarding the Roto 25, it needs a tuned pipe, it's anemic otherwise. I suspect the Evo26 is the same.

[guinnb]

Wow, thanks Jeremy! High praise indeed. I still can't wait to get a V2 in your hands after seeing what you did with the Colts foam prototype

Soto's, thanks for the info. Makes you wonder about the specs listed for props and rpms if tuned pipes were being used. From similar mufflers I bet the pipes will be lighter anyway. Did you see this with yours?

[Sotos]

There's just a couple good threads on the Roto 25 floating around, can't quite recall which site. The performance gain the pipe achieved IMHO is what made the little gasser a viable option for 3D. Does it offer the strongest most bestest power to weight ratio out there, well, no. Does it offer enough power to hover an 11 lb plane at less than 2/3's throttle? Yes it does. For me that's enough though I realize that many insist on hovering below 1/2 throttle. On a sub 10 lb plane, it should be great power.

On the weight savings of the muffler, I'll have to weigh next time I think of it. I have a tuned pipe in box for an Evo 26 I have in box as well. I doubt the weight savings is much as the tuned pipe is quite long, however it does move the weight closer to the CG, and behind it as well.

I gotta have one of these.....very cool guys. Yep, Andy you suck...lol
