Home Despot Ultralight ......"Motor Glider 101"

A: Why not name it 103? (Stall speed. Drat!)
B: I like different, and this is different!!!

(From the link)
Power is provided by two 10 HP Tecumseh motors are mounted directly onto two
by two's, hollowed out in the center with 1/8 inch plywood on the side. No
rubber mounts are used for the engines, but it would be a good idea. Power
from the two 10 HP engines was transferred directly to the props, no gear
reduction was used. The props for the prototype were homemade and were
"whittled out of wood." They were redesigned several times until optimum
performance was reached. The wings have a plywood main spar, the ribs are
Styrofoam, and 1.7-ounce Dacron sail cloth is used as a covering material.
According the Jack he has "over 50 years of experience building planes."

The plane shown here had about 7 hours on it with the last flight made the
week prior to the show where it was on display. Jack reports that it fly's
along at about 40 to 45 mph. When asked how much the average person would
have invested in materials - the reply was "if you go down and buy
everything from Home Depot, the average person will have about $1,000
invested in engines and materials. However, the builder will, carve his own
props or buy some commercially produced." Of course materials like the 4130
steel tubing, sail cloth, etc will have to be sourced out somewhere else.

Tecumseh motors cost more than they used to...

Like alot of things...

IIRC it also weighs more than 400 lbs, nowhere close to being
a FAR 103 Ultralight.

That's why he calls it a 'Motorglider', not an Ultralight.

OTOH if you have (or can get) a glider license with a self-launch
endorsement then a motorglider may be a better choice than
a FAR 103 ultralight.

This is a hoot - AND A MUST READ!!! g

Experimental Glider? YES!!

As a 'Motorglider':
(ii) Maximum weight does not exceed 850 kg (1874 pounds);
and
(iii) The maximum weight to wing span squared (w/b2) does not exceed 3.0
kg/M2 (0.62 lb./ft.2).

500 lbs MTOW
and
28.5 ft wingspan = 812 (wing span squared)

500 lbs MTOW (/) 812 = 0.61576 lb./ft.2

....which does not exceed 0.62!

So yes, it is a motorglider

....IF the MTOW is 500 lbs
....or we go with longer wings
....or we follow the first link. g

Bad Montblack, Bad!
Too much to do today to play anymore on the Groups :-(

That would have to be in the amateur built experimental classification, and
not even as a light sport plan (thus needing a regular glider ticket, not
LSP) because of the two engines, right?

Then, you get to the definition of the span to weight requirements of a
motorglider, which are not easy to meet. I do not think it meets the
requirements for a motorglider, by a long shot.

I'm not sure where this plane would fall, except as a twin engine
experimental amateur built. You would need a regular PP ticket, (or higher)
with a twin engine endorsement, I would think.

I predict that if many people start using this option, it is a loophole that
will quickly be regulated out of existence.

Interesting, indeed.

The Flitplane


Looks like a good possibility, especially for a first attempt. What are the
pros and cons?

Searching for plans, various places are selling them (Raceair, Midwest
Engineering..) Who owns the rights?
