I found that mounting the electronics was rather difficult reminds me of the tiny raptor mount. JR leaves very little room for non-JR products. Wire routing was clean but you really need to bundle the wires in order to hide them in the frame. All of my links went on smoothly with very little adjustment. Really a fun heli to build with only a few minor issues, NOW if I could just get 10 min to test fly it.......

If you going to mount a mixture control servo, just use the Servo mount for the T-Rex 600N.

Remove some of the plate, use a file to move the 2 screw holes sideways a coupel of MM and put 3 flat washer 3mm between the mount and frame in the top of the mount.
The top socket head bolt is 3x45mm, change that to a 3x50mm.

Got my first tank through the Vibe 50 today. Hovered very smooth and no buzzin' fins, the tank was smooth as glass as well While doing the post flight inspection I found the flybar stops were loose in the plastic flybar arms allowing a little slop on the paddles. A little CA tightened them up back up. Explained the slight creep on my cyclic. Still gettin' the engine broke in so no hard flyin' yet.

Guys and experts:

Do you really need to dial indicate the fan in this case for vibe 50? I thought the japanese makes are pretty tight tolerance.

i would nt bother dailing in the fan its ok as is as long as you tighten it up evenly. Iwould be more worried about getting the slop out of the clutch bell.

What do you mean by the slop out of the clutch bell. I would check just to be sure that the fan is true. Mine was under .001 on the first try but I check to be sure. More important is to check the runout on the clutch once it is secured to the fan.

take your engine out and wiggle the bell back and forth and left and right you will then know what i mean by slop. The stck bearings are quite soft and tend to waer out quickly ive gone through two sets already. I think its because the whole assmebaly is held in place by one grub screw.

Are you having issues with both bearings, the 10x19x7 and the 5x19x6 or just one of them, I have yet to check mine.

clutch bell

Good, I’m glad you guys are talking about it. I’m building mine and I’m trying to figure out why I’m seeing my clutch bell go up and down (wobbling at 0.006 in to be precise). I took the assy. out of the heli and noticed some strange figures on my dial indicator. First, the .006 up and down run out on the bell and I’m reading less than .001 laterally (side by side). That is telling me that it is wobbling up and down all right but, strangely, very evenly on its axis! If it was warped in some fashion, it would not be that “axial”. So, CSI like, I looked for something else to blame and looked at the mating between the bell and the pinion if it was true. It is hard to tell by just looking at it, so I dialled it on the crown near the pinion and my reading was .002 but at a 45 deg. angle. I flipped it to dial it inside the bell at about the same distance from the pinion, and I got .003... it’s not true on the pinion. Ok, but it is screwed on, what the hell... but there is a “fitting” of the pinion in the starter bearing bloc that could give some run out but I’m pretty sure that I made it fit in well against the block. So, what do you guys think is happening... is it bad bell, bearing block or pinion? The slop you are talking about, I see it too, it is in the starter bearing bloc. I tough at first the the bell wobbling was caused by that slop but once the engine is in and all is tight, it does not look to me like it is sloping any ware... but the .003 on the starter hex is giving me a wink on things to come...
Sorry about the long reply, it is hard to put in a few words 50 min. worth of testing and probing... so bottom line is, does anyone saw such wobbles on the clutch bell and if so, how “easy” was the fix.
Thanks’

both bearings. The fit isnt that good on the bottom bearing or the top for that matter new bearings help but there is still slop between the bottom bearing and the bell.J.R. should have made a press fit bearing rather than glueing it in with green locktight. I really dont know what to do about the slop I beleave we are going to have to live with it guys .

Well I guess my new clutch bell housing will be the same if it is the bearings and not a warp clutch bell.

But thinking about it. If there is slop, wouldnt I see the low spot move side to side? I only see the low spot on the left side of the bell while rotating it?

theres nothing to say your bell is flat on the top you may have more meat on one edge or in the middle machines work to tollernces and maybe jr think that these are acceptable . I dont like the whole assemmby I think they could have done better. Like i said before the bearings are rather soft and after afew flights mine where in a bad state. the whole thing is reall only surported by the top bearing . One bearing the bottom only allows the bell to move freely. Im not surprised they have a lot of run out.

Just a note guys:

I stripped the 6mm screw while tightening the clutch to the fam hub. Damm it. I think JR should have suggested using a longer screw like 10mm. Or like align use a longer screw with a spring washer?

Also, I did not use the set screw to tighten the torque tube end that was attached the drive shaft joint (page 31). Instead I use the 3mm socket head bolt and a 3mm nylon lock nut to tighten it up. You guys think is it ok? I am worried that the locktite would not hold up the set screw during flights.

I have no problems with bearing slop and had no need for altering any fasteners. My build went perfect and the drivetrain is nearly frictionless.

The set screw should be fine. The load is in shear on the set screw, and there is no force making the screw come out (both ends get pulled by centrifugal force).

But your mod shouldn't hurt.

One thing I ran into, is the drawing for the main shaft bearing blocks wasn't clear to me. And yes, I managed to install all three upside down. It became obivous when I tried to install the main/auto rotation gearset.

So look carefully, and notice which side the bearing flange is on each bearing in the drawing. Not a big problem to recover from, but worth checking out.

What are some people doing to angle the radio tray? I want to build mine as light as i can get it. I even got a new 7100r because it's lighter than the reactorX i was gonna use.
