Here it is. Amazing how much I forgot already.......[and the silly way I acted during the dispute]

Pond Skipper

Thanks Chuck you should have some brass on that conrod if its a Series 3 let me know when you get a chance I am itching to buy one if they are the new version.

the AP .09 does not the .15 does

Yes, this rod was bushed and it looked like it was machined from billet.
I think I can hear it knock when hand flipping, but Jett Engineering claims that their engines are clearanced to do that on purpose. Their thinking is that the rod's big end is continually loaded just on the "up side" of the hole and the low side of the hole can carry more oil.
It makes sense. If you stop the engine suddenly by making an offering to the Ground Gods, then the lower side of the rod's hole is suddenly loaded.

Ohh...IIRC = If I remember correctly. With 18,000 posts, I use that one a lot........

That GLH has a bare minimum thickness wing per AMA pylon rules. 1 inch at the root and that thickness has to be maintained to at least 1/2 span [or words to that effect]. Not easy to hot wire such a shape.
The 1/2 A pylon racers from Utah had no such minimum thickness that I recall, just 200 sq inch. I mention this because those thin winged planes were said to do 110 mph on the level with hopped up AMEs putting out maybe 80 - 90% of a Cyclon.
Those guys ran some slick planes..!

I thought you were serious about discontinuing.........on the heels of the rumor that Thunder Tiger is history [posted recently].
I wonder what the world wide sales figures are. Every where I look there are signs of over population, except with our hobby...vacant, un-populated land is so abundant that everyone is flying 100 cc gassers.

Pond Skipper

Nice I will see If there are any photos from them chaps.

I went with the .12 due to the low end idle adjust for a rock solid low end that won't fizzle and dead stick the plane is my wish.
Also the brass in the conrod and billet aluminum a major plus.
Also the series 3 has a matching exhaust to the OS which makes a MAC header and pipe matchup possible.

Be the first kid on your block to raise the timing to 190...!

Pond Skipper

Yea lol .. sorry couldn't resist!

Gassers are cheap enough to set up these days due to the advent of the net teaching folks what, how and where to buy making it a no brainer for anyone able to fly a 40 size plane to leap up to gas.

Pond Skipper

Looks like I have seen their site before

I grabbed a set of plans for a CAM racer and was astounded at the size of the wing. Must be to do with local rules or 1/2a pylon rules that I don't know about. Then again I am guilty of small wings at times and I don't pylon race - if I did I might appreciate the wing area and aspect ratio more.

Pond Skipper

Whats the name of the plane?

Yea 200sq in makes them a bit of a floater but if you chop the nose off and use something bigger in the .07 -12 range should make for some heart thumping thrills.
I looked at the V tail Dominator and the Caliente could do a mucho caliente hehe

The name is actually CAM Racer. I bought the plans as I wanted an example of typical 1/2A pylon models. As it turn out my destiny is more along the lines of half the wing area and straight line speed.

Pond Skipper

I can report the wing area posted by the Skorch at 88sq. in. is plenty for straight line 10 to 14oz

MJD

As soon as I flew the Toucan, I knew wing area for 1/2a could go wayyy down from the 118 it has. I think the smallest .049 model I've flown was the Squirt (which gathers dust waiting for rebirth) using a single ACE straight panel. It glided very gently after shutoff. Flew like a drunk swallow the first times due to a surging belching finicky Sure Start and need of lead in the nose. got it smoothed out but ripped out the engine and parked it waiting for a better engine, some fresh paint and new hatch covers. I think the AME .061 would be a good choice. I have to find out if it runs though, I did the Toad mods to the piston skirt and crank one foggy-brained late evening - still to find out if I helped it or killed it LOL.

Pond Skipper

The thicker fat foil of the non taperd Ace foam wing is enough 96.25 sq. in.
17 7/8" x 5.5" Its too much for straight line speed passes.

MJD

My Feedback: (1)

Oh yeah I know that. The Squirt was not a speed design.. it was an odd looking little low aspect ratio sport model. Those airfoils are thicker than they need to be for anything.. except for making strong enough foam wings.

MJD

If I redesigned it for a better wing it might be a fun little thing..

#37 on the list.

I'd like to contribute a little over view to this thread. Bob Reuther was a friend for 40 years, and we worked, traveled and raced together. I don't remember any conversations about the Lil Toad, but I'm sure we had them, because I was working for Bob when I published my 1/2 A Delta. Secondly, if you were talking about my CAM Racer, it was published in the Feb,1977 issue of Model Airplane News. It did not meet AMA 1/2 A rules. AMA rules had a wing area (200 sq. in.), thickness, fuselage cross section, and weight requirements. The CAM Racer only had 167 sq. in. of wing area, and target weight of 18 oz. This was 39 year old technology! At the time we were racing what would have been called an "Out Law" class, or as we referred to it as "unlimited" 1/2 A racing. Our only rule, at the time, was no pressure; suction only. If you can get your hands on a copy of that Feb. '77 issue on MAN it has a lot of neat old stuff. The cover shot is of Phil Kraft's Super Fly. I flew with Phil in his Pitts S-2, and he flew with me in my Bellanca Super Viking. Phil said I could fly his Super Fly, but I considered that he was joking? Page 3 has a picture of Mel Larson, Vice President of Circus Circus, with Walt Schroeder. Mel had a history in stock car racing, (NASCAR) before moving west. Reuther, by the way was legendary racer too, and had the last pole on the beach in Daytona, FL. I had the distinct pleasure of flying with Mel in one of the pink and white Circus Circus helicopters. Those are a few memories. It was a neat time. Greg

Hi Greg Doe from Smyrna Tennessee!! Thank you for checking in that was a enjoyable read!!

Here are pics of a C.A.M. Racer I am not sure who built it.

Pond Skipper

What did the C.A.M. stand for?

Here is my Skorch you may have seen the thread 88sq. in wing ply rolled fuselage 5ch.
Test flown with a TD .049

Pond Skipper, Nice looking airplane, and thanks for the kind words. Our 1/2 A racing event was a club event. The club was the Charlotte Aero Modelers. Hence it was a CAM Racer. Sorry I don't have time to ramble right now. Greg

When I opened the plans and saw the name, I thought - wait a sec, didn't I see that on the forum? Guess I wasn't imagining it, real glad you chimed in Greg.

'77 I was 16. I think that's a Jackson Browne song.
