Hello gill. Good luck with your build. Did you indicate your clutch?
I find it very hard to indicate the shoe with any accuracy, indicating the Hub however can make a big differance.

You are right fixit, I should have posted more pics and given a better explanation.

As you can see the shoes are "off" 0.003 thousands of an inch from each other(note the piece of tape at 12, 3, 6, and 9 oclock). You will have to take my word that that the clutch body/one way bearing runs true. This was not easy to do because the stock engine ran out 0.0015.

I ended up machining some runout in my hub on purpose (I didn't have a choice as my three jaw chuck runs out about 0.001" When I mounted the hub I marked it's location with with a felt pen, gently tightened the bolt on the taper, indicated the hub, and noted the results. I then removed the hub rotated it about 90 degrees and did it again. I kept doing this till the hub ran less than about 0.0005". When I machined the countersink for the clutch on the hub I probably was around 0.002" oversize. This play was "corrected" before tightening the bolts that hold the the clutch to the hub. That is what you see in the pics.

By the way this is not a Helibug clutch hub. It is one I made for myself. I'm glad to see this conversion using the rc engine this way. I hope I'm not confusing anyone. My point is that even with tight tolerances held on the parts if you don't indicate them in you could easily end up with 0.005" thousands of an inch or more runout.

Ok moving forward. I received my aluminum pinion bearing support and installed it and as expected it fit right in. For G.P.(good practice)I dial indicated the clutch and hub as seen in the pic and it had less than .0005 runout so it was spot on. Then I proceeded to put the frames on. One note is that you should install your servos on the frames before hand but you already know that. Also the electronic tray is moved a little forward from the stock position. You also need to mount the servos with new hardware as the stock servo hardware will not work.

here are some pics.

Thanks for your time

Looks like you will soon be having fun with your HeliBug.
You don’t have to fit the servos in the frame first because all the electrics are up front so its pretty easy fitting them later, just fit the battery tray with the front lower canopy mount bolts so it’s hinged, now you can just tilt it forward to fit and tidy all the wires.

Nice pictures showing the dial in rilandtg ,

Have you tried a bit of paper in-between the hub and the chuck jaws when using a 3 jaw? You can normally dial it in perfect with a little perseverance by adding a little packing

I’ve used them before when I’ve been stuck the gas will rot the impeller very quickly but if you pump some old nitro through it straight away it will washout the gas and last alot longer.

RC clutch hub removal

For those that don't own a hub puller

If you’re RC engine comes with a clutch and you don’t own a hub puller this is a quick and easy way of removing the hub.
Just find two bolts and put them in hand tight and then just take them down a 1/4 turn at a time until the hub pops off.

very nicely done Gill.
The thing that worries me is the distance of the main blades to the tail blades. They look mighty close to me. What is the size of your main's?

Cheers

My main blade size is 720 and i have flown this heli pretty wild with no ill effects. This 700 wont be thrown around much anymore since i plan on using it for AP and long flight times. Thanks for your sharp eye and your concern.

Thanks

Looks like he’s taken care when fitting the tail box on the splines so that the tail blades are horizontal when the main blade crosses over the boom; I ran 710s on my HeliBug without any issues until I smashed them

How’s your build coming along M8?

I see what you mean Peter. But when the blade comes around after a turn and a half the tail blades are vertical.

Nothing yet as I told you that the shop is closed till the 4th. When I get back to work I would have all my parts and start building.

Stuck at home for a week with nothing to do.

Cheers

PS reading the forums alot though.

Ya i might just get impatient and fly the sucker. Im not sure if i need a tach for measuring headspeed or if i can just wing it and fly. also about the governor i was thinking of getting the GV-1 and a regular magnet pickup because the stock align clutch bell still has the magnets in it. well if anybody can get me some info on this that would be cool.

Thanks

I've used the Stator Gator for rpm signal in 3 gassers now with no issues. One had the CSM revloc 20 gov. and my current gassers have the GV-1.

The Stator Gator is plug and play and no sensor mounting or adjusting is required. If you decide to go that route, make sure you purchase the RC version as the PUH version will not work with your engine.

Also, with the RC engine, you will remove the engine kill button when you install the Stator Gator.

So my question is now how would you kill the engine without the kill button is it that you have to close the throttle all the way to kill it. I'm just curious. Also I need the revlock 20 is that right with the stator gator. The GV-1 is out of my price range at the moment.

Thanks again

Yes, to kill the engine, you would close the throttle valve completely with the TX throttle trim tab. You can use the revloc 10 or the 20, but make sure you get the Stator Gator version, which is different from the mag sensor version.

I prefer the GV-1 over the revloc and if you look around, you can pick up a good used GV-1 here in the classified ads for less than a revloc. If you use the Stator Gator, you only need the GV-1 unit.
