I recently installed a new three blade Catto and since I haven’t balanced my prop since 2014 I thought it would be a good idea. (I removed old weight prior to installing new prop). I dont know of anyone nearby with a balancer, except the local Jet Center and they charged me $550 on my old 182 and didn’t even change a thing; they just wrote something in the logbook indicating balance was within tolerance. Boy did that make me angry, considering I had balanced my RV prop before with a dynavibe in a matter of an hour or less.
So, I purchased a new Dynavibe Classic that arrived yesterday and put it to use this morning. This is a really nice kit and easy to use. I purchased the mounting bracket too which saved some time in fabricating a bracket. (Two small kids, not much time to spend at hangar)...
First run: .14 @ 90 degrees (heavy spot)
- Added a bolt to the starter ring at 270 degrees.
Second run: .17 @ 270: (too much weight)
- Moved bolt to 0 degrees
Third Run: Something random, no better.
- Added bolt @ original Heavy spot of 90
- Added bolt AND large Washer at 270
Fourth Run: .02 @ 135 - SUCCESS!
Less than an hour monkeying around. Now I have a Dynavibe on the shelf. If anyone is in the area and would like to try it out i’d Be happy to help.
PS: one advantage of balancing prop when its 25 degrees out is the engine doesn’t overheat!
