Balancers

Dynamic balancers or static?

 

For dynamic, we use Chadwick systems.

The Chadwick 2000 is a fairly basic, easy to use system.

 

Hope Aero is the distributer for the Chadwick.

Static balancers you can get from Dart Aerospace.

I like the Vibrex (Chadwick) 2000 as well. If you want something a litle fancier I like the ACES 2020. If you want cheep - a used Chadwick 177 or 8500 might be the way to go 3-6K.

Yup Swede, busting it out is right! Chadwick 177 for 206, Tracking Flag for the 204, and don't forget the tube steak dipped in mustard for tracking the 204 tailrotor:) I guess the generation gap shows eh? :D

Further to Swede's post on the Chadwick 2000... note the + at the end.. with that software upgrade it can be used to check engine vibe. Its only a matter of time before there is a vibe check on the 250-C20 As it is, the other engines all seem to be heading that direction. T53, Ariel ect.

The Dynamic Solution Systems (DSS) Microvibe II is awsome for 206's through to MD's. Optical tracker (no targets) keeps the track picture in the box so you can compare different speeds, it gives you balance solutions (weight or sweep for lateral and PCL or tab adjustments for vertical) and learns form your inputs. There is no need for the maintennce manual charts as it is all part of te software. All files are down loadable to a PC based program which also links you to the manufacturers so if you have any problems they can see what you are talking about. The engine and airframe spectrum analysis has machine files you can lay over the top of the chart which lables what the peaks are caused by or multiples of.

 

I have been using one for approx 3 years on 2 bladed FH1100's, R22 & R44 to MD500's (C, D/E, FF, N) and also a S76. All you do is download the a/c type from thier database and away you go.

 

It does take some thinking when initially learning how to use, but once you get to grips with it you will find it a fantastic tool.

How much do you want to spend? A used Chadwick-helmuth 177 is cheap but you are still standing outside trying to diddle the dials. The 2000(+) is user friendly and with the photocell no standing or diddling required, definitely a good choice for most work and still my personal fave. Stay away from the 192 unless you need to measure vibes at 120000 rpm as the stupid cards and crayons are obsolete and bulky, you might as well use an etch-a-sketch. If you have the bankroll, go for the Chadwick VXP, it'll do everything except turn the wrenches.

 

Important!: Find someone to teach you how to balance, as there is still no direct replacement for experience.

 

Cheers!!

That is where the 177 shines. Drawing your own polar charts teaches you so much in regards to what all the moves are doing. Getting hard to get parts for and the computers, just like all computers, are faster and easier to use ( when they work)
