My Vision 90 is my first nitro heli. What does one look out for to detect vibes on a nitro heli? I recently had my maiden flight and it went well. What I observed is that the tail fin was steady (no vibes), no tail kicks, and the canopy near the rotor head was "flapping". Is that due to vibrations or the wash from the blades? Anyway, I'm looking for some tips on how to detect if my heli has vibe issues or not, thank you.

Bad Vibrations!

What's up Chad?

Alright i have only seen one nitro heli with nasty vibrations and it was a .50 size running a nova. I have seen and heard of two different ways..

1. I believe its called an accelorometer...

2. I have seen someone put thin sound damping material on the inside of their frames during the build.

Not sure how either will work but i'll do some research tomorrow. I'll let you know what I come up with!

Thank you. Is there anything I can observe during flight that tells me I have a vibration issue? I guess what I'm asking is while my helicopter is flying what are some "tells" that my helicopter has a vibration issue?
I don't know if my helicopter has a vibration issue, that's why I'm asking. It seemed really smooth during the maiden, but then again this is my first nitro heli and I don't know what to look out for.

Is it FBL or FB? One thing I have seen on nitros is the muffler deflector. On my 700N during spoolup or when I was tuning, the muffler deflector will shake real bad when vibes are high. If it's flying smooth I would let it ride.

It's FBL. I'll watch the deflector next time as I didn't pay attention to it.

Theres basically two types of vibes High Speed, Low Speed. high speed can be seen in the tail fin vibrating and foam in the tank. Low speed is like wobbles, fuel sloshing around in tank and canopy vibes.

Vibe issues

You can look at the front electronics tray.If it's shaking alot you may have a vibe issue do to your engine not being tuned. If the head wobbles or the tank foams this is a good indication of a bad vibe issue also.

if you flying a new kit I wouldn't worrie about it to much. if you have at least mm gap between your clutch and the top of the bell just fly and have fun....Also make sure you have the new gears sent out by elyq to rcheliworks. some older gears were causing tail vibe issues.

Thx CB.

Take extra caution alignin the engine and clutch. I had a hard time at first and it was vibratin everything. Now aligned 100% better. And yes a bad engine tune will do it to.

Aligning the elyq motor

i perfected a technique which took me along time!I was fighting alignment forever on this thing causing major vibrations i have found the best way for me which has worked everytime. With the motor out and the screws loosley in clutch stack take one screw out of each of the blocks so you can see the threads and the hole. Set your mesh on lower block tighten up one screw then i matched the upper hole location with the lower. Tighten and screw everything up now. Next install the motor. Put the screws in just enough so the motor still can move but not so loose the motor can move itself under its own weight. Glow plug out of the motor stick your starter in and spin it a few times around. This will line everything up! tighten all motor bolts down. This has worked great!

Wifeorheli never thought of this way to align the motor.... Thx for the info.
