Rotor Track and Balance training in SA

Unread post by Mike G » Wed Jun 26, 2019 4:04 pm

I have been tracking & balancing gyro rotors for a few years now with the Smart Avionics PB3 and now their latest PB4. I've balanced just about every European type gyro and rotor around.

With a colleague we set up a small company to teach rotor track and balance (RTB). We've trained people at the following factories; Magni, ELA, AutoGyro, Trendak, Silverlight, Brako and Gyro Tech. We've also trained a number of distributors, dealers and owners. See our website
http://www.vayavolo.com/rotorcraft-balancing/en/

I am planning to come to SA around October/November this year and a friend who has a hanger and office at Springs has offered to let me use his place as a location for a 2 day RTB training course. My friend isn't a gyro guy so we'd need some gyros to balance as part of the training.

Would there be any interest?

Does this only apply to gyro rotors? What about rotors under power (helicopters)?

Hi there

I would be interested, will be bringing a Titanium Auto Gyro (TAG) with.

From our website you'll see that we ask for at least 4 participants to make it worth my while doing a session. I don't have to do this for a living, I'm retired with a reasonable pension and do this mainly to keep me busy and meet fellow gyro owners so it has to be worth my while or I just stay at home :).

From bitter experience I know that about 50% of those who say they are "interested" don't attend when they realise they have to pay or simply don't turn up when I arrive. So I'm looking for more interest before I decide to put this session on and (because of previous experience) will be asking for a deposit to cover my expenses in the event that people don't show on the day. So, I'm afraid, we'll need more interest.

From the website you'll also see that the standard charge is 500€ per person. If you are still interested please email me at vibrations@vayavolo.com with some details about you (owner or dealer/manufacturer), your gyro(s), how much "hands-on" you are with your gyro maintenance. This gives me some idea of the level I have to work from.

I hope we can get enough people together for this to happen, spread the word.

Hello Mike,

How about answering some of the questions above then maybe you will get a better interest Sir.

Sorry I thought I'd replied to your question but I realise it's not posted here so I must have messed up.

There's no doubt the PB4 balancer can be used for helicopters, there are a number of heli owners using it.

At the moment I have a little experience balancing helicopter rotors. I am working with a European light helicopter manufacturer to develop a track and balance procedure for the Smart Avionics PB4 balancer but it's a long job because whenever I'm available he isn't and visa versa.
So with our summer holidays coming up I doubt if it will be finished for my visit to SA. Even if it were finished I'd not consider it fully tested enough to propose teaching it to a paying customer.

The procedure we are developing is very much based on the procedure I developed for Smart Avionics for gyros and that I present during my training sessions for gyros. If we get enough people together to do a gyro session at Springs you are welcome to sit in and we can talk on the side about what differences I think (or know) would apply to your heli rotor. You can pay me what you think it's worth when we've finished.

Are you currently balancing rotors and if so what system are you using?

I am booking my flight to J,bourg.
I plan to arrive on the 4th Nov and leave the 18th Nov. I shall be busy from the 4th to about the 9th and available for any Rotor Track and Balance (RTB) training session that we can organize at Springs from the 10th to the 18th. I presume that anyone interested would prefer the weekend so if really necessary I could try to reorganize my program to be available for the weekend 9th & 10th.

As I said earlier if you're interested the total cost of the 2 day training session will be 500 euros per person, I think that's about 8000 Rands. I'll need a deposit of 100 euros to ensure that people turn up on the day. I propose that you can pay that part of the fee in Rands say 1500 Rands and it could be paid to my friend in Springs (he's somebody in the SA powered glider world, trustworthy and in country). If I can't make it for some reason you'll get your money back from him of course. Payment of the difference will need to be in Euros or dollars I’m afraid.

The training session is in 2 parts.
Part 1
Is 1 to 2 hours long and is aimed at the average gyro pilot to teach him about the different types of vibrations he'll experience and how to detect the major ones (1 & 2/rev) by the seat of his/her pants. It gives some hints on how to separate out the different vibrations (rotor, 2/rev, prop, engine etc). It explains how a balancer works, how the results are plotted on the Polar chart and how to understand the frequency analysis. All this with no math. This also serves as an introduction to the main 2 day session. Usually we charge 50 euros for this so if you’re interested in just doing this part let’s call it 800 Rands cash on the day.
Part 2
Follows on from part 1 and is about 3 to 4 hours class room with different Power Point presentations taking you slowly through how to track and balance a gyro rotor using a Smart Avionics PB4 dynamic balancer and how to interpret the frequency spectral analysis to detect rotor/ prop/engine vibrations. We also go step by step through a number of real rotor RTB's that I have done to give the participants more experience without the time lost flying. While the training is based on the PB4 the techniques and procedures are applicable to any professional type rotor balancer.

Part of this class room work is broken up by actually balancing one or two rotors depending upon availability and time lost due to traffic in the circuit. So we obviously need some gyros to work on (the owners get a free track and balance). If time permits we also cover a prop balance but I rarely have the time there are so many questions.


Part 1 is aimed at the average gyro pilot who wants to get an idea if his rotor needs balancing or not. He will also understand what the guy who’s balancing his rotor is talking about and should be able to interpret the polar charts and vibration spectra and ask educated questions.


Part 2 is aimed at the real enthusiasts who want to invest in a dynamic balancer and track and balance their rotor. I do not sell dynamic balancers.

If you’re a Magni driver you will also learn about the latest Magni adjustable rotor design.

If you’re interested please contact me at vibrations@vayavolo.com with some details about you (owner/dealer/manufacturer) your gyro(s), how much “hands on” you are with your gyro maintenance. This gives me an a idea of the level I have to work from. I also need to know which dates you prefer.

If you need any references about how good (or bad) this training is contact Abid Farooqui at Silverlight in Florida or Jason Knight in Texas, they're both on Facebook and the American forum.
