vibe 90 build question and build pics
Okay one more question. I am running BLS451's and they dont really fit in the aileron and collective slot back to back.. Are you guys shimming them out?

The kit went together pretty fast... well I guess the fact that once I get started I cant stop. I'm really happy with the quality of the vibe even if it is the older model well worth the price. Only thing I don't like is there "flybar control arms" I definitely will be changing that out before I fly it. Oh and there seems to be a complete lack of space for electronic placement and mounting. Anyone have some pictures of their electronics layouts?

Got the electronics in tonight couple loose ends to tie up but almost there.

look for a Spektrum AR 7100 Rev sensor, it works good with most Governors like ATG and GV1.

Otherwise, drill some holes into Fan shroud and fan, and mount the sensor there. But it is a nasty work...

Or buy a Vibe 90 SG it has some holes in the clutch and a sensor holder

On the 'regular' Vibe90, you have to make the hole in the fan for the magnet.

Just to make sure I had enough 'meat' I selected an area just over one of blade of the fan.

I have the pump on the back plate...

I guess I will just drill a hole like you said. Any specific distance? Or does it not matter?

yes you do have to add sims or the carbon servo plates to space them out so they can fit without hiting each other, im running 8717 and i had to sim them out and even now they almost still touchRicardo Maldonado

Mount the bracket and the sensor, then mark the spot on the fan.

You can take a peak at my gallery (mid portion) to see a Vibe build and layout of the electronics.

I put up some new pics with the electronics installed.

Can someone explain the grip flip thing to me? Is it just simply changing the side the grip control is on? Do I have to flip any other parts? I tried doing a search but did find what im looking for.

Is the geometry right or did I do something horribly wrong with the main grip link? It just doesn't look right. I'm still waiting on the KSJ flybar cage I really just don't trust the way its currently designed.

Mdu where the heck did you put your gyro sensor at?

rsimon, that is the corect head assembly. The pitch links do have a large angle to the grips like that.

Thanks guys for catching that. I kept looking at that aswell I just couldn't get it to go in all the way. Finally after some messing with it, it is seating all the way in now.

this is what horizon ported on thier website about the tailbox.
please do every word as they say and you will never have an issue with the tail............

Through reports from some of our Team JR members in the field it has come to or attention that there have been a small percentage of Vibe helicopters that have experienced severe tail vibration and in a couple instances lost tail rotor blades. This is obviously a very serious condition that can result in a catastrophic crash.

Through extensive research we have traced the cause to an improperly secured bolt on the tail clamp (#JRP960133) thus allowing the tail rotor gear box to rotate on the tail boom in flight. In some cases the tail rotor blades strike the vertical fin resulting in the grips and or rotor hub being destroyed. In less severe instances a resonance (vibration) occurs in the tail rotor system/gearbox. This resonance is primarily occurring when the tail clamp (#JRP960133) is insufficiently tightened allowing the tail rotor gearbox to resonate in the tail boom resulting in extreme stresses being placed on the tail hub, blade grips and tail blades which in time will fail.

Important: The tail clamp (part #JRP960133) fastens the tail rotor gearbox to the tail boom and must be securely clamped in place to prevent gear box rotation and or tail resonance/ vibration. This requires that the 3mm x15mm socket head bolt (JRP980015) be securely tightened such that the clamp compresses the tail boom fixing the tail rotor gearbox in place. It’s necessary to use adequate force when tightening this 3x15mm screw so that the clamp compresses the tail boom firmly securing the tail rotor gearbox in place. Note that the tail clamp is also used to attach the rear portion of the vertical fin in place. It’s very important to fully tighten the 3x15mm socket head bolt that tightens the clamp and secures the tail rotor gearbox in place BEFORE the vertical fin is attached. If the vertical fin is installed first it’s possible that the screw attaching the fin to the clamp will prevent the 3x15mm clamp bolt from fully seating preventing the clamp from securely fastening the tail rotor gearbox in place.

When tightening the tail box you should screw the long screw (3x15mm) on the tail boom clamp (its the bottom screw) as much as you can. Also, do not tighten the set screws too much.

If you buy any flybar cage, choose the Quick UK one. Its expensive than KSJ flybar upgrade but much more durable. I had two failures on KSJ flybar cages and I can post the photos if you interested.

And one more upgrade : Its the MA 0844-12 one piece head dampeners. These are the perfect replacement for hard JR O-ring dampeners and if you don't want to face with a boom strike on the air please use the hard ones.

I don't mean that there is a boom strike problem and something wrong with the model. If you use standart hard durometer JR O-rings you should replace them regularly (this is also up to your flying style). If you use MA dampeners instead of JR they will last long because of their design.

Thanks for the info guys. Does this look a little better

I think for now im going to just run the dampners that are in it and then change them out after about 30-40 flights and then upgrade.

As far as the grip flip goes I pulled this off of the CY website

Hi Curtis.

Do you know if JR will have an upgrade kit for leading edge blade grips modification, where all the items are included?

Answer
No extra parts are needed. You just flip the grips over, turn one of the short ball links around 180 degrees and hook it to the other blade grip. Then reverse the swashplate direction for the collective in the radio.
Nothing else about the head has to change.

I just flip the blades over and connected them to the other side with the short link. The first picture is how the manual said to do it and then the next two are the flipped. Is that correct? I know my blades are now on backwards and needs fixed

Man that just does not look right although I realize it may be. If you get any binding at the extremes, it looks like the links will just pop off Team MikadoUSA 480XXTreme, 550SX, 600SX, 700XXTreme, 800XXTreme!!

Thats what I thought as well, in theory you would want the link and the ball to be 90 degrees to one another right?
