Epiphany

Well. this will be old news to many, and new to others, and unthought of by the rest.

Seeing posts on suggested engines, the S.O. 40/2 PF threads, RoJett/PA, Saito, 40 VF, 4-2 vs. wet 2, pipe run, stunt run, ad. infinitum, I had what the commercial is alluding to.. finally.

Take as an example the OS 40VF and a PA 40, both on pipes. (these are two pipe engines that I have some experience with)
They will each like a different style of run. The OS, to my experience, likes to turn a little higher rpm, and maybe a little less prop dia.

A Tom Lay ST 60 will have a different run than a Big Jim ST 60.
A Rojett 61 and a PA 61 will have a little different run.
A Stock OS 25 FP will have a different run than a SSW OS 25 FP.

BUT, they can all be made to run in a more than acceptable manner if we aren't tied into only one mode of thought.

All in all, I think we are best left to run the different engines like they are supposed to be run and not try to make them run otherwise. If you know someone that is getting great runs, find out what they are doinf to get them. If you want to take the same engine and get another type of run out of it, then you will probably have to do a lot of experimenting.

I fall into the Blind Squirrel/Finding the Acorn syndrome. I get very good engine runs, and I have never done much experimenting. I just ask. If you like to experiment, fine! I just don't have time to do both. I can either fly when the opportunity presents, or I can fiddle with engines. My time is limited. I will tweak a prop, or touch the needle, that's about all.

Thoughts from the assylum!

I think this concept has been enumerated in a number of Buck missives on motor run. I don't have a problem copying other people's work in this area. I hate tinkering with motors!

Bill, to me this concept isn't really complete until you work with whatever setup you have for dozens or preferably hundreds of flights. Then you learn the subtle modifications to the basic setup that really make a difference for your plane. (Thats my good natured way to say get out and fly more man!)

Looking forward to burning tons of fuel at Huntersville

I agree.

I know how to make an ST 60 work.

I have dozens of props for them.

I have no intention of ever learning how to make a 4-stroke or a pipe work. My time will be spent flying what I know, not fiddling with engines

"Epiphany"

A semi-elliptical stunt plane designed by Pat Johnston. Flies very well on an ST60 or SSW Magnum 53

I've only seen it at one contest, and wondered why not at more? It is a great looking airplane, as I recall. Got any pics of it? Hey, shouldn't you be on the road to Clovis? Steve

Steve,

Not me. Having to pay my son's college tution, uh, put a crimp in my plan. No trip anywhere but to work for me for a bit.

I don't have a picture of Pat's plane (now owned by Jim Welch). I'll see if Pat has any. I do have the plans, though. It is, in fact, a cool plane.

Hey Bill. I know what you mean and at times I wish I had never met a Fox .35!! Too easy to form bad habits when trying to run todays engines.

Bingo! Ty gets it! Not surprising, just good to see him raise his hand.
