I haven't been happy with the feel of my full size blue Vbar on my Synergy N7 and ive just tried mounting it as follows, white 3M VHB tape (its about 1mm thick and hard to compress between your fingers), Spartan metal plate (quite heavy), another layer of the 3M VHB tape then the Vbar sensor. It now feels better and im happy with it!

60% of the time, it works every time!

Unless you are running a silverline, the best mounting I've found for nitro helis is:

heli-zeal tape-Spartan plate-thin hard foam tape-blue or black vbar sensor-nylon tie-wrap running through silicone fuel line and pulled tight until zeal is squeezing out from under the plate a little ..........the "Milton Mod" as some have called it.

I tried MANY combinations of plates and different foam tapes on my Vibe50 and this is the only one that worked 100%. Until I bought a silverline sensor for it. That one I just stuck on with a single layer of the mounting tape it came with and it just worked.

This is how I had it before.

I tried your way and it didn't work on my heli. The different methods must work better canceling different vibration frequencies..... So there is no "one method for all" solution.......except for buying a silver line sensor.

The Milton mod had good vibration resistance in a hover but not so good for jerky low frequency vibes that occur during 3d.

I just use the stuff provided with the vbar and if I don't have that plain old 3m double sided white works for me on electrics.

Richard, that is the same method I used on my N5C. Worked well but for electrics a single piece of Mikado Tape does the trick for sure.

You need to pull the tie strap really tight or yes, you will see the above problem. Use a tie strap that's at least an 1/8" wide and thick walled (ie: dubro - large) fuel tubing as well.

Electrics have much lower vibe levels than a nitro so you can usually get away with a single layer of tape.

I've never had a vibe problem on any of my electrics....except for my Embla when I had unknowingly preloaded the mainshaft bearings when tightening down the retainer collars in the wrong order. On the bench with no mains on, it ran smooth. As soon as I bolted on the main blades and pulled into a hover, the vibes were off the chart. Took almost a month to figure out what was causing that.

I've always used two layers of Futaba tape(3mm), the heavy Spartan plate, and then thin(1mm) white tape under the sensor.

If you skip me I can't play!

And no velcro strap?

No, I've never had to run the strap or fuel tubing/zip strip.
But I do/did replace the tape yearly.

That would be way too loose for me! Maybe without the metal plate but with the metal plate its going to wobble around more.

That's what I thought too, but the strap actually made more vibes.
Maybe it depends on the machine/motor setup and flying style as I prefer larger smoother maneuvers.

I have a TT X50 with a silverline and the sensor is stuck down solid with a slightly thinner tape than the 3M but holds just as firm. There is two exceptionally good pilots at my club who have T-Rex 700s running OS105 with the v-bar sensors also stuck real firm with a thin tape.

In all cases the models fly without issue and without seeing any vibes upsetting the electronics.

The way the sensors are mounted with no movement they could have been stuck on with superglue!

I should mention that is how I mounted the blue/black sensors, the new silverline I put down solid with 3M or stuff it came with.

Thanks Doug.

This has nothing to do with flying ability, as I really am just an average joe. More about what works when mounting a flybarless sensor.

You and I have tried a lot of different mounting methods and materials over the years.

+1 for the silverline.
I can even tell the difference on an electric...although this is about a Nitro isn't it. Lol
