Aero28

It is time consuming to get both wings square to the fuselage center line, lot of measuring and I put a drone up and took photo's.that worked 🙂

I was wondering how you were progressing Marty, we are about at the same stage I reckon

Time to fit the wings and tail to do a weight and balance to see how its going.

Thanks for the info Phillip, I have a muffler like that on my yellow plane, have a look at this video

It's 16mm ally KG, might weigh 3 to 4 kgs

More pics

Yeah, good Nev, I'll go and see what the stainless people have, 1.2mm wall would be good

I started building this plane about 6 years ago. I always thought the Zenair 701 was a good ultralight so I drew my interpretation of it and have started back into it. I had the EA81 in the yellow plane in my member pic but changed that out with a 2000 hour 912 . I had already mounted an old EA81 in this plane so it made sense to bolt the good one in. I'm trying to lighten the 81 as much as I can, lots of lightening holes, a small permanent magnet alternator, i'm thinking of 400mm of steel exhaust from the heads and then into aluminium to the muffler, any thoughts on that?

I like that the magazine is still with us but as I am a builder there's not much in it for me. Tech articals are what I crave and totally sick of the safety rant. It must cost a fortune to print on the heavy weight paper, could it not be done like the American Kitplanes mag, smaller in physical size(not so much white space around photo's and text blocks) and printed on lightweight paper. It doesn't have to look like a Vogue mag does it?

This is how I do it ,I haven't flown behind one yet but this is an easy way to carve them.

Oops, yeah "C" Gearbox

Hi Richard, Buy a Rotax 2.6:1 B gearbox , save yourself a lot of net searching and angst. I spent a long time trying to get a belt drive to run true on my EA 81 but gave up and bolted a Rotax to a 16 mm plate to the bellhousing , now I have a smooth runing prop.(72 inch three blade Warp Drive). I paid ...I think $1960 for a new one off Mr Flood about three years ago. Cheers Paul.

Looks like the starter gear is permanently engaged to gear 42, unlike a conventional solinoid activated starter.?

I've been thinking about tail draggers and nose wheel aircraft .....and what we are doing is emulating birds, and birds are essentialy taildraggers. I haven't seen any birds with a third leg coming out of their chest. :) I made one to see what it would look like and he doesn't look happy. Taildraggers forever.

Just for you Doug.... I ran the fattening tool over it :) now a two seater. Made the vertical fins bigger too. Bit of a trade off there, don't want them too big , might induce flutter but still need slow speed control. Cheers Paul.
