Just some WW 1 R/C model pictures .....

i seem to recall years ago, someone was building rotary engines (110 LeRhone?) for scale a/c. I've never seen one (I recall they were VERY expensive), just wondering if they were ever produced. Looks like these birds would be good candidates for something like that. With the investment, I'd be more inclined to look at it on the ground than try and fly it!!:icon_lol:
 
Thanks, that may be the one I was thinking of, but could swear I saw a scale LeRhone. Could have been a prototype or one-off.

Its been posted on this forum before but worth posting it again.

Enjoy,

Now THAT'S! what I'm talkin' about!!!:jump: That LeRhone is SWEET!!!!!!:applause:
 
Pretty amazing, I'll say

Wow, what a gas to to see these fine planes. I wish I were there that day. What fun. I was wondering how many of the good folk in that club/meet know about OFF. It seems they could get into such a fine WW1 sim. Thanks for posting this.
 
Pardon my ignorance on the subject, but HOW the Heck can they lite-off 7 glo-plugs at once, and spin the engine to boot to start. If the engine itself was stationary ala a radial OK. Made to look like a rotory OK, but even if spark plugs were used, where they come-by a seven cylinder magneto, these things do not grow on trees ?

As in the real thing, you don't need a 7 point mag. It uses contact buttons on the back of a ring on the rear of the engine, kinda like a big, exposed distributor in older cars (for those who remember those days!). The mag (ala coil) supplied the juice, as the engine rotated, the contact buttons on the ring passed by a stationary contact and completed the circuit. Each button on the ring was wired to a corresponding spark plug.
I would assume that the model is true in every regard, and they seem to run on ethanol, so I would think a miniature spark plug would do just fine. In the case of the model engine, all parts are created from scratch.
 
Makes sense, I just wonder if the Caster oil was a dyalectric, or a conducter. One would think that a rubber slipper seal, would work.
 
Are you seriously telling me, these cute little engines do really run? And pull the plane up into the blue??? Wow!!!
We can build and do such amazing things with the same hands that pull the triggers...

To my understanding, Caster oil is an insulator, more so when congealed. You had to be sure that ring on the back of the engine was clean so the contacts could be made, otherwise, no spark, no fire, no fly!!

Yes, they sure do. Did you check out the video WF2 linked above? That was the point of fabricating them. I saw one of the early prototypes at ORA some years back, very impressive bit of machining skills.
 
WOW. That Avro 504 is awesome. I want one......but not to start off with. Ive never flown an RC plane before and it would probably end up with the prop in the dirt. Hate to have all that great craftmanship go to waste.

These are the "spark plug wires" for that engine.

Great pic of the rotary, CJ, now I understand, how they did it with the ignition of a revolving engine. And that V8! Awesome!!!
