Does the Helitronix Mixer really make your multi-bladed scale helicopter easier to fly? In a word, yes. But don’t just take our word for it. Read what our customers have said.
These are actual quotes or entire messages from our customers relating to their experience with the Helitronix Mixer and gyros installed onto their multi-bladed helicopters.

First off I need to thank Joel for designing this gem and Joe for making it available to us to purchase.
I bought this a few weeks ago to test in the Vario 300c with the 3 bladed head. I was very skeptical about not only the product but also the 3 bladed set up. After installing and working with Joel to confirm the setup was correct I was ready for flight. Unfortunately the weather was not cooperating for a few weeks so I decided to load it for the fun fly and test it in a open area.
All I can say is I burned two tanks and it was as stable as stable can be!!! I wish Megan would have gotten video instead of the pictures but I have the guys to attest to the stability of the system!!! Heck I didn't even have to adjust the gyros!!!
Thank you Joel for making flying multis fun!!! Now I'm putting a multi on the Allouette III!!!!
Have either of you tried the Helitronix mixer. It has been working like a charm on my bk. Might do the same for you guys. Just a thought.
Forward flight was really a non event. I just cruised it around pretty much like I would with any other machine. If I had thought it was going to go as well as it did, I would have had someone shoot some video. Maybe next weekend.
I added the Helitronix mixer and a gyro when I put the mechanics into the fuse. It really seemed to take the edge off. I flew it a lot in pod and boom form without the mixer, and I would have to say it fly's better in the fuse with it than it did out of the fuse without it.
I need more time on it, but my first impression is that the mixer works very well.
I was amazed at how little I had to fight with it to get it to go where I wanted it to go.

After sending units back and forth to Joel, I finally got to try the latest version today in 10-15mph winds. It was obvious at previous testing sessions, that it was going to be much easier to adjust and measure the gains by doing it from the transmitter.
I set the gains at 51%, effectively zero, and nearly wrecked my heli, it was so uncontrollable in the wind. I set the elevator to 60%, not much improvement showed. Up to 70% and suddenly flying got easier. 80% and the heli was a lot easier to fly. I could keep it in one place in the hover, but it went up and down like a rocket due to the wind gusts. The pitch controllability was a function of the ECCPM setup, which was very crude and needed more time on it.
Then I eased the aileron up to 80% and didn't notice significant changes. It seems the aileron is not really an item which benefits greatly from the gyro, it’s all in the elevator.
Finally I eased the elevator up to 90% flew it and didn't like it, although it wasn't bobbing. Back to 80% on the elevator and 65% on the aileron and into very fast forward flight. To cut a long story short, I forgot I was flying a Vario 4 blade head, it was so nice.
Conclusion? It’s great. If you have a Vario 4 blade head, this mixer works just as advertised and is a great help in the stability stakes. I suggest you may just want to buy one gyro and add it to the elevator channel, the aileron channel doesn't seem to improve things greatly.
I'm glad this thing is working well, I had my doubts at first, but now it is a serious addition to the scale heli armory. Anything which helps people fly multiblade heads has to be a big plus in my book.
AWESOME!!!! Are you using the Helitronix mixer with gyros for the head......if not you are missing pure enjoyment!!!
Then bravely dragging more cahones out of my navel, I loaded up a set of blades on my newest 135, a pure virgin here. Multi, with the Helitronix on it. Yes, it hovered, the tail was out of adjustment, so I landed and shut down, and found the set screw was slipping. Yahoo NO CRASHEE Yahoo..... Flew a full tank on her and found her like hovering any flybarred head I have flown. Wind gusts had no effect on the head at all, no pitching in any direction even if hovering crosswind. Yessss Yesssss Yahoooo

Hi Everybody,
I just want to share some of my experiences using the Helitronix CCPM mixer for flying multiblades. The setup that I have is a vario petrol mechanics with the CCPM frames on a vario Bell 412, 4 blades head. I am using 4 Futabas S9402 non digital servos to control the head. I also using a Helitronix CCPM mixer. The mixer is setup to have 45 degrees of phasing and the mixer is connected to a Futaba GY 352 multi axis gyro. The connection between the mixer and the gyro has an ?specific order? so when unwanted movements are detected in the heli the Gyro responds sending the signal to the Helitronix mixer so the mixer convert the output of the gyro to the appropriate phasing..... and that’s it! Make a note that if you are using a GY 352 you need to calibrate your sensitivity quite different than other gyros such GY 401. In case of the GY 352 the sensitivity have to be set at 80% that translates to about 12% on conventional gyros.
Results:
I did 4 flights with the setup mentioned above to perfection. The heli was extremely solid in hover and transition to forward flight was very impressive.... we did have some breeze coming up but no problem on handling all situations. In my setup I can turn off the GY 352 and let me tell you is quite hard to fly the heli like this?.. almost unthinkable?.. turn on the switch for the GY 352 to come on and is a joy to fly.
I just want to conclude to say thanks to Joel and Joe for such amazing product you guys make multiblades a joy to fly.

I have both the Helitonix Mixer and the Vario MB Gyro and the difference in effectiveness is huge. The Helitronix is on the heli and the Vario is on the shelf.

First off, let me make it very clear I am not contradicting someone else’s opinion about multi blades. What this post is about is what works for me.
I got my Skyfox Fenestron Multiblade trainer flying today. I put one of my mixers and a pair of CSM gyros in up on the front tray. I wanted this set up in 4 servo as I wanted to compare, so Futaba 9202's on the Vario double bolt head. New engine to break in for another project, so I had it rich enough it dropped a beat now and then, enough to feel just how effective the fenestron is.
I had this setup before and only used my radio to do the mixing part and the phasing, so I knew how it worked without gyros. That is why I wanted to try the mixer on a trainer. Now let’s be real clear here, I barely fly circuits, I do figure 8's ok, and I fly low, slow, and hover well, but I am not the best pilot, but I can fly easily in 10 mph wind.
I went out today and only flew a half tank, as my transmitter battery ran down and I had to land, but I did some low figure 8's, hover, slow turns, and experiment with how the wind effected it.
This friggin mixer/gyro setup is just awesome!!!!! This thing flew exactly like a Skyfox trainer. I couldn't believe it. I was spending more time correcting the tail than the attitude, no pitchiness even in gusts of wind 9mph. I just don't believe the difference. It did not fly the same as the scaler, it was much quicker to respond......probably half the weight. This just blew me away.
Once I get the feel for it better, I am going to increase the weight and get it up there and see how it effects flight.
Awesome product, highly recommend it.
