A good way to learn the balancing process( with a Dynavib or Aces computer) is build yourself a small balancing "teachers aid" Use a small electric 120 VAC motor and a 8 inch circle of plexiglass or acrylic bolted up to a hub and mounted to the motor shaft. Flair tip mark the degrees and etc on the plexi and drill a bunch of holes in various places in the plexi. Use SMALL 10/32 screws and washers to create unbalance and use your new toy to balance it back out . Worked for me, and helps learn the sequence and what the machine is trying to tell you. Actually sold the aid along with the ACES Sport at some time later. Probably best to keep you motor RPMS to around 1100 ( no 3600 RPM motors)

Good Question! I did not ask him, but I will. I did mention both brands to him and he chose the ACES.

I can give you my opinion of the dynavibe classic and the aces 1015. If you do not know that much about balancing, the aces 1015 will be easier to use. The dynavibe classic gives you raw information and you have to make the calculations. The aces will give you weight solutions and split weight solutions. With the dynavibe, you can easily proceed through the first two solutions but if you still want to try for improvement beyond that point, it gets more difficult and the math gets harder. In all of the videos i have watched on the dynavibe, they manage to attain a vibration level that is acceptable in the first two runs and never proceed beyond that. The software in both balancers allow you to take multiple samples at the press of a button. No two of any samples will be identical because of the many factors in play. Wind and prop wash is probably the biggest players involved. It is possible that the operator in those videos took multiple samples until he got a solution showing excellent results. I don't know. With the classic, you can take multiple samples, write them down, then select what looks to be the median solution. With the aces, the software allows you to either accept or reject a solution but when you resample, the previous solution is lost when you proceed. The solution you accept may not be the best solution.

If you make more than two runs with the classic, most people would probably not know how to accurately adjust the weights. You could do the math just like the aces box or the more expensive dynavibe box does but it is lengthy and you have to know how its done. The easiest method is triangular addition of vectors on a sheet of paper and you can get an excellent solution with a dynavibe classic, probably equal to or even better than the aces.

If you are having difficulties with the classic, contact me and I may be able to help. The classic is a good box but just takes a little more effort.

Just used Dynavibe clasic equipment when I was installing a brand new GT2V38 blades on this amazing 14A based in NJ.With 3 engine runs reached 002 IPS. Great equipment and great team.
