I'm cleaning my Shuttle os32 (a biggie hehe) and the back plate gasket is compromised, torn. I was thinking of using red gasket maker Loctite brand, which I must use to seal side cases for a certain Honda motor bike this year (that's how they do).

I could cut a paper gasket and use the red gm between the metal surfaces of the back plate and motor case. I'm wondering if anyone has used the gasket maker in a location that depends on absolute sealing under pressure. The side cases on a motor bike are not under crank case pressure like that of a two stroker.

I figure with the .002.5 paper wetted with the gasket maker that this would be better than the gasket maker on its own.

Take a look at this dude's nitro Shuttle, one pull and zing, that's how I want it,

Watch at YouTube

I have the pull start variety motor.

You know, I could have a 2013 Trex 700E complete and built in my hands right now (local hs had one a guy bailed on a brand new for $500 off, or a 2012 600N for $600 (no rx), but there's only time for so much, first things first, "one step back, two steps forward" as they say. This is how we doo.

I'm looking into a 21mm tail tube for the Shuttle, as a dealer says they can make ANY diameter and length.

I find a lot of the old dog birds are better off getting converted to fbl and it's easy to do while keeping the old fb head but removing the fb cage and other associated nasty bits, as long as you're having fun.

Get a new gasket. Its worth the wait. If the sealant gets inside the engine it could give you problems.

I made a mistake once, but I was wrong?

it's red loctite 515 gasket replacer, not red rtv automotive gasket maker. Guys over apply that stuff in engines and it comes off inside, clogs the oil pick up, and the motor ends up oil starved and seized.

I've converted a few astro vans to v8 one a ground up 305 with Rochester quad producing nearly 300hp, was kind of fun to see that result, a friend stole it just a month after it was completed. I did build a raced Chevy 350 v8 that made it around a race track ten laps before the rear oil seal fried and caught fire. I told the young owner to PRE-OIL the mains before he used it, nope, he didn't do it. Big boy toys, lol.

anyone used the 515 alone as 2 stroke case gasket? I'm certain the out of town hs has a gasket but if I don't need it I could have this project in the air in a week.

Those are 3x40mm's from the local hs who specialize in rc truggies/off road/nitro cars. They use them for the steering and shock linkages a lot.

I had to tap the rh out and drill left hand dubro links with slightly undersized bit. I ran the link ends off and on a few times until they were not very tight but snug only. that way they would turn without damaging the link ends.

You have to scratch or mark the direction on the tb with an arrow and it's orientation as to what thread is left hand and what is right or be prepared to use a magnifying glass to make sure you are adjusting the turnbuckle properly, cool ehh? Keep the rh on either the top or bottom on both links to make things simple,

See the nice rebuilt clamps I made with the old ones, one cracked? a little more write up in the Hirobo forum if anyone is interested,

Please tell me you have a solid feathering shaft on that rotor head. The original Shuttle had a dual flapping arrangement that was a nightmare for boom strikes even in mid air.

yes it's solid.

is that a bad thing? guess the pull starter adds a bit of weight now that you point it out. the components do add up.

My first Shuttle O.S. .28 had the belt starter. It was a real PITA. My second engine, a .32, had a rear cone starter. That was better, but if you flew planks also you had to remember to reverse the wires because from the back of the motor the cone has to spin clockwise. My last Shuttle, a .32 also, had the pull starter and I tell you that was absolutely the best. One or two pulls and that little baby was hummin'.

Glad to hear you are using a solid shaft in that head.

Nice to hear. Pull starter ads a quarter lb to the bird.

I discovered a loose tail belt bearing seat above the flywheel, and an out of round flywheel flange, all needing correction. The broken fan probably vibrated the flywheel and sent vibes up through the pinion shaft. The bearing was flopping around in the frame seat. I'd like to cut out the plastic and install an aluminum seat, not too hard to do.

Now beginning to close up the motor section, next is up front to place all the e things nice and tidy and run a sat (maybe off the boom underside where blades can't kill it), and a few pulls from airborne. Wasn't a write off after all.

The Shuttle will sport fly with 10+ and about 6- pitch. It has the original wood asymmetrical blades for the time being.

the 515 will work as a stand alone sealer,

but it doesn't matter, I went with a paper gasket and the 515 The OS is all closed up ready for mounting, only the pinion shaft bearing seat to deal with and the motor is in, very close now.
