Sounds great Andrew, what size? I reckon either 48" or 60". My preference would be EPP wing and fuse with balsa tail surfaces. I'd be keen to build one too.
I think I could make some Hummer cores, I'd certainly love to see another one in the air. I had the original cores CNC cut over a year ago by Zipper but could probably cut some more at home, just have to make the templates. I cut the fuse myself - I have a template for the fuse so cutting them is nice and easy.

Ding, the Bullet came much later than the Rico. It has a wing optimised for speed - I forget what section he used. There's 4 or 5 versions of the Rico, basically the same fuse with different wings. The slope version is what Thevon has - it's the dedicated aerobat version. Future Slope Designs planes are sold in Oz by Kane at www.slopeplanes.com . I've met Kane once, he's very keen to promote slope flying and he is trying to stock a range of the good stuff. I haven't yet done business with him. Ken. Cool Ken. I didn't know they had a specific slope aerobatic Rico... I thought that was the bullet. Still they shared the same body, and there isn't much side area there. |

Sean - great! My Swinger is 46" and I suspect it's a bit small (with a decent fuse and all EPP it could be high wing loading?) but I wonder if 60" is a bit big for a Shorncliffe zinger. I'd be keen to go for around 54" - what do you reckon?
Since I've been pursuing this for SC I was wondering if the name should be SCaero, or SCabatic, or something parochial like that! Doesn't sound as nice as the Mickey though.
I reckon I'd probably make a lighter Hummer version as I wouldn't be aiming for any records with it - I'd like to pension off the Reaper and Bat for one good all-round DS Hummer. Probably put the Bat's ballast tube in it too (560gm).
For the benefit of my work and family it would probably be wise if you had lots of delays and interruptions to these projects; so it's a long time till I get the cores and become obsessively compelled to spend countless hours in the shed , then try to find every opportunity to fly them, then spend many hours writing long missives on forums about them.

54" would work I reckon. I'd like to try symmetrical and non-symmetrical aerofoils to see which worked best. The Wasabi foils would be my number one pick - they're symmetrical but to make them more efficient at soaring they're designed to be used with camber changing.
I can do that! (too well I'm afraid)...
A light Hummer would be interesting. I'm sure it'd go well. It'd be hard to build light with the current spar design, might be worth building it with one one spar per wing? That would make the build less involved. The wing shape means it must have four servos though.
