Any of this CNC'd or straight hand machined? Any left-over parts? I have two Deckle Pantographs, and an SO ctuuter grider in the garage (and a Bridgeport) so......I'd like to build one.

I found it on the net and don't know anymore about it than what's been said here already.

[jhagen20042000]

the only thing about these engines that leaves me clueless is...IGNITION ? what fires this thing ?

[standallas]

Spark plugs. As you can imagine the ignition wire rotating at speed were vunerable to breakage but generally it worked!

[enginetorque]

have you seen the flying one in the UK

[standallas]

Which one the avro or the morane?

[mbitsko25]

For those who wonder WHY they'd spin the engine around a stationary crankshaft: 1. No alloys to build high speed, high-horsepower engines. They had to make TORQUE at low speeds instead. 2. Low speed, high-torque engines shook the planes to pieces. 3. They tried huge flywheels, but wasted too much power. 4. Solution: Use the engine itself as the flywheel! A bonus was excellent cooling, and they were able to almost eliminate cooling fins, which were expensive and complex to machine.

I salute the dude that made this engine. So awesome

@jhagen20042000 for origional rotary engines you have two magnetos. one runs at full speed when hot, the other has 3 seperate speeds. you could slow down a rotary by adjusting the left mag. it worked by lenghening the number of revolutions it takes for all the cylinders to fire.

@mbitsko25 and as a side note, unfortunatly, they made manuevers tricky at times due to the gyroscopic forces they generated, which is why these beutiful engines are now rarly used.

Somehow missed out! Please write again at a oh well after my name as one one word. Thanks.

@spikeboogey123 : Haven't had any luck at all finding Ray via the Interent. Could some one please lend me a hand here? Thank you.

[paullubliner]

@spikeboogey123 : Hey I would like to contact Ray, can you give an assist? The great Nieuport 11 would be my choice for one of these.

Este motor estra en venta???? me parece un motor maravilloso.

[spikeboogey123]

He scratch built a 1/3 scale AVRO 504K for one engine and a Moraine Saulnier (sp?) parasol for the 2nd

[spikeboogey123]

The guy who made this engine is Ray Williams, of Chadwicks N.Y.

He's made at least 2 that I know of.

Excellent (Master) machinist just begins to describe his workmanship. I still have a T shirt w/ the oil spatter all over it from this engine...it's won't wash out...lol

[paullubliner]

Actually the Le Rhone 9c (as modelled here) was throttleable from 900 RPM to 1200RPM (there is no "s" as in RPMs!) Still too fast to sink in say a 759 pound Nieuport 11 --so yes the blip switch was essential if you desired to land.
