[Second time around]

I have purchased an RCV 120. Test stand results showed quite a bit of vibration .
Is this normall .
Any information on it before I mount it in this below
Thank Ken

I've got the 90. Uses an 18x12 APC. Right out of the box, no problems. Initially, I would suggest:

have you balanced the prop?
what about the prop "hole". Is that off centre a smidgen?
or is there prop wobble in that the hole is a bit too big?

Difficult to say without actually seeing it.

NO! and it's not recommended either.

From their site:

What is a typical noise reading?
Noise readings are completely dependent on numerous environmental factors (ground cover, buildings, traffic noise) so specific Db figures are hard to give by any engine manufacturer. To give an idea the following noise levels could be achieved at 7m:
RCV60SP - 80 - 82 Db
RCV90SP - 80 - 86 Db
RCV120SP - 82 Db upwards
The RCV however is marginally noisier than conventional 4-strokes, so in clubs with very tight noise limits (ie. 80 Db) consideration to reducing the noise through building and installation will be necessary. NB. We do not advise rubber mounts due to the high tortional vibration.
