Are these aircraft in production? I haven't seen one for many years and then very few. I guess I missed it, because I didn't know either one made it into serial production on any scale. They are certainly attractive. It would be interesting to see series production of composite gyroplanes by...

Thank you Abid. Jim

Gyros have not kept up here either. The gorgeous fuselage shapes of American Ranger, ELA, TAG, Magni, etc are just shells bolted to metal frames. The frames consist of a welded metal structures laid out much like the Bensen. A mast, keel, landing gear, control tubes and cables. I would...

Hi Chris, I haven't kept up. Did you give up flying? Jim

Sorry to butt in, but the KB-2 and the KB-3 are very different. Jim

Mike, I built several RAF gyros several years ago. There was a fuel crossover line between the lower lobes of the tank. I don't remember routing of the lines, but surely someone here does. Jim

Thanks Ron, As Bobby pointed out, there are Marinas in the Phoenix area that carry E0. Unfortunately the drive is pretty long to get there. I measured the gas out of the pump and the water added, and it looks like right at 10% Ethanol. I'll probably start using Seafoam and check the fuel...

Reportedly worked pretty well for the Luftwaffe in the 1930s

Yes, it is. I'm not sure I have a problem. Everything seems to be running great. The ethanol thing is a puzzlement to me, and I don't care for puzzles in my aviation endeavors. If I have to, I can run 100LL and change the oil every 25 hours. Even with Decalin and frequent oil changes, the...

Thanks Ron and Bobby. I'm surprised at how much the level changed. Costco premium gas.

Hi Jason, RAF, or any other manufacturer of kit aircraft components cannot require replacement of anything. They can use the word "required" but it only means the kit manufacturer wants you to do something. Their "requirement" has no force. I know you may know this, but RAF, Magni, ELA, AR...

I agree with Eric. Brian Carpenter and Roger Lee know a lot about Rotax engines. They both teach trouble shooting procedures that emphasize returning the engine to a known state (factory standard) before beginning to throw parts or adjustments at the problem. I can't resist a short example...

Thanks. Thus far, I have been unable to find E0 gas except in 5 gal cans at $12 a gallon. I burn 100 LL in my Gobosh because of the fiberglass fuel tank. Change the oil every 25 hours. My TAG has a cross-linked polyethylene tank so no problem with ethanol. I try to burn gas within a couple...

Anyone use Sta-Bil? I have used it for decades in lawn equipment, boats, motorcycles, etc. Haven't used it in my Rotax 912 ULS. Any comments, facts, anecdotal info? Thanks folks Jim

I wasn't clear in stating the reasons "WE" weren't able to make the larger gyros scale well performance wise. We worked with Boeing Phantoms works, DARPA, Georgia Tech and others. Contractors or consultants included Ray Prouty, Gordon Leishman, Dan Somers (did the airfoil for our rotor...

Did a PAPR this morning. No exceptions noted. Jim

Yes he was. Al loved to sell. I've lost track of him now.

Yep. It is. Thanks for starting it Tommy. Brings back good memories of John Potter, Don Farington, Al Wadill, others who shared the 18A adventures

A very nicely written piece has been added to the https://spinningonthewind.com Web site. Home page, scroll down, August, 2024. Chris, do you think Shirley would mind you serializing her writings for your electronic PRA effort? They are beautifully done
