RCBC remember that the Sandlin GOAT series is a monoplane with reduced parts count, easier assembly, AND higher performance compared to the BUG. So it may be close enough to what you want already. Floyd Fronius equipped a GOAT with swing-out electric motors that really looked like a clever solution for self-launch gliding.

Heck yeah! I've got Bloops 1 through 4 on my PC at present and working my way through them whenever I have a quiet moment. I suspect I'd better look through his other ones too...

Brilliant, thanks for the tip - I'd only looked at the Bloop plans so far, I'll start reading through the Goat asap.

You'll be glad you looked at the Goat

There are some of us who respect Rutan’s knowledge and abilities, but don’t admire his designs.

Ah. Apologies, seems I overly generalized.

It seems that most people agree with your comment; they admire Rutan’s designs
Probably some nit-picking here, by me.

Note that I did include Burt in my Hall of Fame list https://www.homebuiltairplanes.com/forums/threads/eab-hall-of-fame-designers.20245/ for his impact on homebuilding.

Several others there, too, whose designs had positive impacts on the world of homebuilding, but are designs that I do not admire.

Sounds like we will have an interesting topic for discussion at the OSH'19 HBA gathering.

Mark Beierle from Earthstar, a small boutique factory in California, has an all metal electric single seat that is Ultralight compliant. He uses Zero Motorcycle battery systems. Mark is a good resource for electric implementation.

See here..

Mark's wing has one of the best lift coefficients you can find. Worth looking at if you are into that side of things.

I owned the two seat Odyssey model for a while. The wing was the heavy duty model and made wing on and off way too difficult. Not like you see in the above video at all.

Mark explains the cost / payback factor of $1 per hour electric versus$20 per hour with petrol. Flight time is short. Engine reliability and fuss factor compared to the HKS 700E is long.

Awesome, I'll look into that one. Yes, that's what appealed to me so much about electric - the low maintenance/hassle factor and flight hour cost. Short flights - and a high initial investment for batteries - seemed a small price to pay for most of what I want out of my aircraft.

With the short flight time of electric, unless it's something like a self launching sailplane where motor is just a means to get altitude, you may eventually find it limiting. Like paramotors... they're a blast to fly, but your rarely go more than a few miles from the point of takeoff. If you find you want to expand your horizons the limited range might start to intrude.

You're likely correct - while I currently feel like a short-hop fun-flyer would be more than enough, that may well change once the disease really takes hold.

That said, I think I may be able to hedge my bets a little - I'm planning to design the rear of the craft in such a way that it could one day have a (small) gas engine fitted instead of the electric power system, if I get a yearning for 3-hour flights etc. Because I'm planning to carry a sizeable pile of batteries in the electric version anyway, there would be little to no net weight increase. CG-wise, I'd planned to have the batteries a little rearward, as my (electric) motor would be too light in pusher config to balance pilot weight up front all by itself.

(If I did go that route, I don't think I'd be running anything bigger than a Moster 185, so performance would be similar. For anything faster/gruntier, I'd go clean slate, as this is a bit of a point-design bird I think.)

Another two good sources for implementation of electric power are Chip Erwin and Brian Carpenter.

Chip at .. https://aeromarine-lsa.com/zigolo-mg/

Brian at .. https://electricmotorglider.com/emg-6/

Chip's electric Zigolo UL may not be in production but he is very knowledgeable.

Brian's EMG-6 is a DIY plans built and all plans are open source. As a motor glider, the EMG-6 may match Dana's suggestion just above.
