Lose the castor, it is not needed, I haven't used castor in my fuel nearly 20 years.

Glowgeek

Lean out the lsn and keep 2-3% castor. The lsn controls fueling from idle to upwards of 80% throttle. Some, but not all Saitos run very rich in the midrange when the lsn and hsn are set up to what we would call acceptable standards. That is, 250-300 rpm rich of peak and a sustainable idle with snappy transition. If you spend all of your time flying at 0-50% throttle adjust the lsn for cleaner running at those rpms. Once you get it running leaner on the bottom end you may find it wants to cough out and die when slamming the throttle open from idle. If so then slow your throttle servo speed a bit.

NIce cap. Now you can keep the daily flyers assembled in it for quick morning jaunts to the field😉
Looks great with the slash cut.

Glowgeek

Looks great Dave. Now all you need is some custom 22" wheels with "rubber band" tires and then you'll fit right in.

Oh, a drop kit would be awesome too.

Dave, I have a similar topper on my Chevy Colorado. About 3 or 4 times a year I have to slide the topper back about a foot to clean the back cab window and the topper window. If I don’t it gets to the point I can’t see out of the back. Part of the problem is that I live on a gravel road and the road dust gets in there.

I ordered my topper to have a drop down front window, makes cleaning them so much easier. Since I had to buy new, might as well get that option. Finding a used for a 2016 was near impossible.

I too live on a dirt/gravel road, that dust on the pipe tip id from a single trip. Thanks all.

1200SportsterRider

Actually I was considering raising the front 1.5" so it would sit level front to rear but since it has struts with huge A frames/arms at the bottom, raising it would change the angle of the A frames/arms The rack and pinion steering looks as if it would work on Peterbilt.

Are there any Saito you guys would like to see run with certain sized props? I need something to do besides mowing.

Saito 50

When I was a teen I remember my Dad's F150 having a Leer Bed Topper. IIRC there was an inflatable donut that went around the rear truck window between the cab and topper to keep dirt and grime off.

I keep coming back to installing this Saito 182 on the Rascal 110, I think it's doable, there won't be a lot of the cowl left, but.

Glowgeek

How about a split cowl? It's not too hard to put in a couple of basswood beams for it and you have to cut away a lot less cowl, usually. Those intake tubes and needles make it a challenge either way.

Looks like a perfect fit. Even mo betta, the heads and valve covers will peek out the sides for awesome aesthetics and great cooling. I have mounted my 300 twin (lesser liked OS) on a third scale spacewalker and it is eye catching as it passes by. And idles all day long with no onboard glo thingies. I say go for it Hobbsy! And send video!!!
Looks like an offset to the left? never seen that before?
Unrelated but Saito. Like to learn the history of the R3 engines. This series with its multiple problems intrigues me. My R450 early nitro motor runs so sweet. Seems like the three problems the later engines display is related to the conversion of fuel to "dryer" gasoline and heat related to its use vrs methanol and its cooler running and additional oil unburnt by the excessive heat?
Sorry guys, excessive covfefe this morning. LOL nervously.

Split the cowl at the centerline of the heads. That will make it easier and give the cowl a more realistic look too. I glued strips of PVC to the top, and had it overlap the bottom so that there was something to screw into with small #2 screws. I used round head allen screws. This is how I attached the Liberty Sport and the Rascal 168 cowls.

Glowgeek

PVC strips, great Idea. I've used basswood beams in the past but pvc sounds better, no chance of splitting and semi-pliable. Thanks for the tip.

acdii

Acetone melts the strips in place so no chance of them coming off from vibrations either.

1200SportsterRider

The firewall is offset 2 degrees to right so the offset verticle centerline sets the prop driver at dead center. Thanks for the suggestions.

Hyjinx

Great project! Love the Japanese twins. Lol

I am going to make a card material mock up of the cowl side and transfer it to the cowl using the measure twice, cut once method.

Glowgeek

I don't really "measure" anything when making cowl cutouts. This vid shows the tried and true method I use.



First used the method on my Sbach and it came out perfect on the first try. Been using it ever since.

It certainly is different, it flies and that certainly deserves credit. It would be easy to model.

1200SportsterRider

Let us suppose a guy, (me) for instance wanted to build a model of this thing and use an FA 30 s for power and a 6" tube. How do I figure the length, wing span, tail feathers etc. An FA 40-a is available also. Some of you may have some software that might help.
