Hi=20 Bill,

I = did get a quote=20 from DSS today, and also talked to them about the personal = balancer. =20 They seemed fine to deal with, so maybe it was just me=20 yesterday.

Anyway, the=20 personal balancer is a no frills unit, that only gives you amplitude, = and=20 phase. You have to do all your own calculations as far = as how=20 much weight to put on, etc. The unit, with no sensors or cables=20 is $1795, and the normal kit they sell is $2885, but includes two=20 accelerometers, cables, etc. I can easily see how you were = trimming=20 this down to about $2400.

While not fancy,=20 it will do what you need it to do, but there is an rpm limit of 4800, so = you=20 can't balance any engine parts above = that.

I = also exchanged=20 a couple more emails with ACES, and found that they have a 2015 = unit, that=20 goes for about $3900 in a kit. The unit can only acquire data from = one=20 channel at a time, though it is a two channel unit. It and = the 2020=20 both come with only one accelerometer in the kit though. They = originally quoted the 2020 because I had mentioned it would be nice to = do=20 helo blades if necessary. They did say that you could do = rotor blades=20 with the 2015, but it wasn't = as convenient.

I = plan to call=20 the ACES guy tomorrow, and decide what to do (if anything) = from=20 there.

Thanks,
