Bob Holman still sells the plans and laser cut kit for the 68 inch version. I just bought them a month ago. I think that is the original, in this thread, that is being converted to electric.

RE: Ceramic Coated Exhaust...

I think the idea is preventing heat radiation keeps the exhaust gas temperature higher. Higher gas temperature has lower viscosity so less flow losses.

RE: What creates lift with fully symetrical wing?

Thanks for fixing that, a cube has 3 sides!. I think people would guess a room full of air weighs less than it does.
So a room, 10 x 20 x 8 foot cieling is 1600 ft^3 x .075 lb/ft^3 = 120 pounds

RE: What creates lift with fully symetrical wing?

A 100 x 100 ft room holds about 620 pounds of air, at .062 lbs/ft^2 and 100ft x 100ft = 10,000 ft^3

A 5 lb model helicopter hovering over a scale large enough to catch all the downwash would...

RE: 1/2a Biplane

Thats it !!!!!!!!

Thrue, 6 x 18 inch doesn't scale from that drawing of the actual plane. I scaled it from a .40 size published in American Modeler magazine - take a look

RE: 1/2a Biplane

I am thinking of a 1/2 a bipe using one set of ace constant cord foam wings I had.
After you add ailerons, they come out to a six inch cord, and each section is 18 inches long.

RE: Building the House of Balsa A7 Corsair Propjet

I think it would be cool to scale one up for an inverted rear-exhaust .60, with a tuned pipe exhaust hidden in the fuse, coming out the tail.

RE: os 61sf

I would think these old piped .60 size engines would have a hard time beating a super tiger .90 from a cost, weight and performance standpoint (at $119.00 it's lookiing pretty good in that respect)....

I have read that you can use monokote trim with the windex method over Ultrakote, so you get the advantages of both.
