Guys, sorry about the brutal photography! Here are a few pics of where I am at in my 90SG build.

The set-up is:

140 degree ccpm
YS91SR with Hatori pipe
GV-1 Governor
GY611 Gyro with 9256 servo
Hitec HS-7940TH servos on the cyclics
Futaba 9452 on the throttle
Duralite 6.0v regulator (5.1v step down for Gyro)
Flightpower 7.4v, 3000mah 2S2P receiver pack
Futaba 6014HS receiver
710 Rotortech main blades
105 CY tail blades
I run a Futaba 12FG radio on 2.4

So far I really like the kit. Great quality parts and good, clear instructions. This is my first JR heli, so it takes a little while to get used to the ball links and the engine alignment, but no real issues or problems.

One question for anyone reading this...do you need to clearcoat the canopy after the decals are on? I have never done a canopy with decals before, so just not sure if they stand up well to nitro residue? I'd rather not clearcoat unless necessary.

There is about 2 feet of snow on the ground up here in Canada, so we'll have to wait another few months 'til spring to see how it flies!

Looks great. It seems like we're seeing a lot of SGs these day on the forum. Santa must have been nice this year!

I don't think the decals will hold up without clear coat.

Happy flying.

Regards,

They will hold up, (surely not has good as if you get it cleared), but if you clean it at the end of the day - it should last at least one season until maybe some of the sharp ends start lifting a bit. (This should bring you close to another Santa gift season anyhow )

Thanks guys...I guess I'll slap a layer of clearcoat on just to be safe.

One more question...is there any way to "self align" the clutch while the heli by slightly loosening the bolts that hold the clutch bell and then brining the heli into a hover? Then re-tightening the bolts once the bell is aligned.

I ask because with a Stratus, you can loosen the bolts that hold the engine plate to the frame, and then hover the heli, then land and crank down the bolts. This generally "self aligns" the clutch assembly and gets rid of most vibration (provided you have dial indicated your fan properly).

Based on what I have seen in these forums, it looks like with the VIBE SG there is no need to do this, and you can just visually align the clutch into the bell?

I align it on the bench and tighten the bolts down.

With a piece of paper to set the main gear/pinion mesh, I put 2 popsicle sticks underneath the clutch and use these to hold against the clutch bell. I then tight everything down - a 2nd pair of hands helps during this !

Once it's done, I double check that the start shaft one way bearing is smooth by turning CCW.

Cool, thanks guys. I like the popsicle stick idea...really simple, and I wouldn't have thought of it. I was already over-complicating it! Thanks again.

I'm not getting the Popsicle trick, how are you putting it under the clutch?

BTW, ditto on the nice kitchen.

Not sure exactly, haven't tried it yet. I think the idea is to pull the clutch bell upwards with something level and then crank in the assembly that holds it in place. Like I said though, I haven't tried it yet.

clutch bell

Its very crucial to get the bell and the clutch in place so that they are parallel in all "four corners" side to side and front to back.
if its out it will wobble! I keep the engine loose in the mount to give it some play, its easy to get the motor tilted to one side or the other
if its bolted down when you are setting it in the bell. On a good note the vibe SG is easy to get set its very close from the get go. Also I find it better to get it all in place and go back and lock tight the bolts one by one. Also the motor mount has a bit of fore and aft play if
you need to get the bell set in that axis. With every thing done right the bell and clutch will sit square, gear mesh will be right and the start shaft will be as smooth as butter!
