Jim i believe your story about the can flying away. I snuck out to the shed one night because i could hear noises and wanted to see if some crittur was stealing my brand new fa182t that i'd stayed up late to run in. The small side door was open and the lights were on, and what a shock, music blaring and beer cans scattered everywhere, found one of these in a box under the bench.

Dave,
This is just about the heaviest 18-6 I have come across to date. Picked up a batch at tha Toledo show.
Not surewhat the wood is but it is heavy, hard and thick. Could double as a Cricket bat or maybe a double tree for a pair of Clydesdales.
They do indeed pull very well.

I think I have a couple of those as well. Was going to use them on the NGH38CC on the B-25 until I found out the 19" would be scraping up dirt. They and the engines will wind up on the P-61 when I build it, instead have a pair of FG-30's with Falcon 18's.

Update on Jester's cantankerous FA80: Carb rebuild done, needle adjustments seem to be more predictable. The engine still ran significantly more RPM at low throttle settings with glow heat than without. A new Saito glow plug fixed that.
Now I have 2400 rpm idle with good transition. It's running 8700 on the top end at full peak, so I tuned it to 8400 and called it good for the first flight on the Spitfire. I can live with that, and hopefully I can get the idle down a little more with some fine tuning.
Thanks to all of you for your help and suggestions. I am certain o rings were an issue, and the new spraybar might have been also. It definitely needed the different glow plug. Sometimes Captain Obvious really should be in command of the ship, so thank you, Glowgeek. If today's moderate success was a fluke, I'll be back.

Jim that's funny, over here the red roos are called big reds or 'boomers' as they grow much bigger than the more common western grey kangaroo. 30 yrs ago my mate steve had one as a pet in his fenced back yard, i think his mum owned it but if you were there with steve the roo was always friendly, they can make good guard dogs. A while later a burglar hopped over the back fence at night and got a big surprise so they had to let the roo go to a friends place out in the bush east of here.
Jester that is real good news and you may be right about o rings, especially the o ring that wraps around the intake tube where it joins the head. I change them once a year if the engine gets a lot of use they tend to flatten badly and go a bit hard over time too. Time for a few beers and some bench racing after a successful flight i say
Dave those power points on your wall look weird to us downunder.
ps capt nice looking model, i like the kite on the back wall too.

Jester, as you fine tune the LS needle the flight times will go up dramatically, the LS needle controls the mixture for about 85% of the throttle range.

Hello Fast Pilot, are you referring to the black hex head screw in the side of the carb? The medium size screw shown here?
https://www.macgregor.co.uk/saito/sai91s90.htm
If yes, it has a specially shaped point on the end that makes the rotor (barrel) move in and out when the throttle lever is moved. That is how many RC engines control fuel metering.

That screw must be tightened just enough to stay in place. There is a small split locking washer which must be used under the screw head.
