This was one of the best videos for using the Dynavibe and this is the first video that included a real world safety briefing. Nice job!!! Just notes to save time: I assembled a hardware kit that includes all fasteners, washers, etc in the dynavibe kit and pre weighed them and labeled the part number and weight on a label. I used a cheap “Hatbor Freight” clear plastic parts tray that has a clip down cover, I also made a set of engine mounting hardware out of a couple stainless nuts for each size tig welded together with a stainless hex bolt on the end. I have rolls of the black gaffers tape 2” that is made by “Lockport” to mount camera equipment and holds well but comes off without residue or paint damage. I also picked up a roll of 2” Solas-A C036 reflective tape “Amazon” that will last for years. Thanks for taking the time to produce this video, it is a great reference. Joel Davidson
At 12:29 you stated that “you always take the weights out and add new ones, they are not additive”. However you stated that you were going to add more weight to the same locations. What did you end up doing? Why did you not just add a washer to the existing bolt/nut combination to increase the weight? Why did you choose to add more weight to the existing location instead of utilizing the programer to tell you where the final weight should be place (which is typically a different location)?
You always start with a fresh, empty flywheel. The unit does tell you where to place the weights an how much. Rarely do I see the same amount added back to the same location.
Sometimes they stay on the flywheel, and sometimes due to belt interference we place them on the spinner bulkhead. No loctite needed. We use either fiber lock nuts or heat nuts, depending upon finding the proper weight.
Everyday is a learning day at Base Leg Aviation. Nicely done.

Funny you just added this. I’m actually considering having a shop do this to my 3 blade catto this week
Do it! Vic balanced the prop on my RV some years back and it was a really noticeable improvement.
Question: If the weights are to be put onto the flywheel, then why is the rotating mass of the spinner not included?

@@baselegaviation1614 so it (DynaVibe) considers that it has 3g at a spot and wants you to increase it to 4g?)
Do you do a final check with the spinner on?
I think it's wise to check with the spinner on. In fact, I just added washers to the spinner screws on my 2-blade hartzell/io360.
yep. we normally have the spinner on. yesterday was a training class in how to use the equipment.
Hello from Sydney Australia.
Maybe a silly question,, but do the."balance nuts and bolts stay in the flywheel? What about Loctite on the thread?
🛩️🌏
i think he used a nylon locknut. may be it works better than loctite?
