Colt 40
I've been brain stormin about what to do with the Saito 50 I have been running lately. I've got it, I have a NIB US Aircore Colt 40 that would be perfect for it. I had one several years ago with first, an Enya 46 MKII, then a Super Tigre 51 Diesel conversion. The Diesel exhaust eventually took all the paint off the right side. I think I'll build it and use the 50 that way. It's a great flyer, landing is simply a matter of throttling back and when about a foot from the ground, go to idle and it settles down as smooth as silk.

Well, as I said I don't care much for the bent wire method, that is simply my preference, it is a simple easy method though. On some installations, when I want the throttle servo low in the fuse I use a double ended servo arm with the servo rod on the bottom and the throttle rod on the top.
That picture of the Duc may end up gone if it starts a MC binge. Not by me though.

but DeForce has picked up there engineers and the JR name. Now they are producing radio’s and receivers under JR pro / deforce. They have all the X-Buss stuff that JR started. It all works great I have the JR/Deforce Radio equipment in several airplanes
i haven't messed with X-Buss yet but it sounds cool as hec.

Got to keep those Saito’s in the air with the best equipment out there.

Just a friendly reminder to keep the theme about Saito engines and not motorcycles 
Yes, the thread drifts out and back a little sometimes but lets try to focus.
Thanks!

I saw one those cloroplast jobbies at a fly-in a couple of years ago. Looked like it flew very nice and the guy said he'd had a couple of them over the years. Said it was a very tough airframe.

Countersink s, used with flathead screws.
Of course, trick is just making it right. Once you have the knack they work very smoothly. Many folks use too large wire . I have only used the DuBro once and picked up on the trombone setup. It was worth the tinkering in the long run.
In most cases you can avoid using either.
Here are a few pics of Counterbores VS Countersink tools. Not unusual for folks to get the two crossed up
Counterbores using interchanges pilots to allow any diameter counterbore with any bolt diameter.
Counterbores are also called \"Spot Facing" to provide a flat seat on irregular surfaces.

The cargo belly was optional too, I did not opt for it though.
The first one I had was the Knight Hawk with the optional flaps, powered by an Enya 46 MKII first then later by a SuperTigre 51 Diesel conversion.

You take the high sliders, they seem to hurt about the most. I'll take the low side
Hopefully the "counter" thing sunk in.

I am waiting on the next batch of Tharpe Flyin King planes. Gotta go YS with this one
Will be listing one of my FA-182 twins and one of the 100 teins, both are brand new.

You guys are overthinking the throttle setups. Just use a throttle cable. I have a couple where the arm nearly touches the firewall, and with a little slotting, a cable works perfectly, that and I can put the servo just about anywhere and route the cable around the tank and batteries. So far the only plane I have not used a cable on is the B-25 engine pods I just finished. I can use a wire push rod for those since it is a short direct path to the throttle arm.

Flyin King's are graceful flyers, my first one went through a dead pine tree going backwards, the stab and the wings were reduced to fuse width in a hurry. I had been flying it with a Fox 74 Diesel conversion and then pulled a bonehead move by not replacing the Tygon clunk line when I installed the Saito. The glow fuel hardened the Tygon and the clunk was sticking straight out into center of the tank, when the 80 went lean it kicked back, spun the Harry Higley Heavy hub off and went tail heavy with no thrust. I have another one ready to cover, just needs some minor sanding, I think it will get a 90-T. I built both with nose gears.

Here of late I've been using these little fellers as throttle servos, so easy to mount.
Cute little guy

Not really. I use flex cable,same as you in almost every situation, especially since I rarely build real small planes the call for anything else is all but history.
With the Saito, flopping the carb so the arm is closest to the outside wall and placing the servo in a direct straight line behind makes for very easy going.
There are some cases, usually with the 20 to 30 size planes where something different simply works better. At that point a little thought never hurts.
I always use high resolution and very fast throttle servos. I like brisk response in that area.
Hey Dave, how about a Laser for the FK? Got a clean one for cheap.

Wondering now if the Hitec HS645MG is overkill for the throttle servo. I certainly don't need the torque, just the metal gear for vibration reasons since it's gas. Would rather use Futaba 3004 instead.
04-29-2019, 04:25 PM
Resolution and speed are what I look for in a throttle servo. Most standard servos have surplus torque.
Yes sir , Lazy Lasers are just that Dave, overweight and short on power. Been saying that a long time.

Dave, I have a couple Airtronics 94141 wing servos, with only 2 flights on them, they are small and light, I have JR adapter plugs on them, they sell for $60. I was thinking about using them of the throttle of my mustang and VQ P-40

Woo Hoo, me get-n me some XBus, cause I got me a wing with 6 wires, 4 servos and 2 retracts, it will be really slick having only 1 wire to hook up when mounting the wing
oops, an edit here, the retracts will be using a Y-harness that came with them
now I got to come up with names for the M-Mustang and the P-40
