OK, I'm fairly new to iKON and to the Jeti Mezon 130 ESC I'm trying to set up. I've worked through several issues thanks to a few knowledgeable folks here and elsewhere. I have a new issue now :arggg: When I pump the pitch on the bench the iKON seems to "glitch", servos freeze for a couple seconds, DSMX sats blink and come back on, then it's back to normal. Every time I increase and decrease pitch, repeatedly, I get this hiccup. When it's spooled up and I do this, in addition to the glitch, the motor slows and quits, then comes back up. Obviously happy I found this before I maidened the TT E700 today!! I'm running the throttle and "auxiliary/programming" wire into the throttle port and an open port respectively, so voltage is split between two inputs.

Can anybody w/ Mezon 1300 and/or iKON experience help me out? The weather is too nice to be inside fixing problems- I need to go fly! ;-)

Thanks!!

Just saw the same thing on a friend's heli. The servos are drawing more current than the BEC and Ikon can provide when they reverse directions together. He put a cap on and the problem was solved.

One additional note- this happens even when moving the pitch up and down slowly

What servos? Do you have both power wires from the Mezon plugged in? Is it the regular Mezon or lite?

Protek 250Ts on cyclic. Powering the iKON via Mezon SBEC which is set at 7.4V (both wires). Regular Mezon 130 RPM.

I'm not familiar with the power draw of those servos, but they say that they should not be run the way you have it setup, so they must draw a lot of current. Here is what Amain says:
NOTE: This servo is not recommended for use with receiver/voltage regulator combo's. We highly recommend you use the ProTek R/C Dual Power Bus Advanced Linear Voltage Regulator, or similar regulator to avoid potential brown out conditions.
Sounds like you need to revist your power setup.

May be, but do you think that three cyclic servos could pull >15A while slowly moving the cyclic up and down?

Dunno, but I'm sure they gave that warning for a reason. I'd be that if you had a full size receiver instead of satellites it would work when going slow, but the 3.3v bus on the Ikon that feeds the sats seems easy to brown out. I've seen it on much lesser servos than you are running.

I'm running the same setup except with Futaba BLS272hv/BLS251HV combo and a Jeti rx and it's solid. But those servos are known to be very low draw, and an external rx wouldn't depend on the 3.3v bus. My buddy is running Ikon, a Hercules BEC with Kingmax HV servos and DSMx sats and gets the same as you, but he does have to move the stick quickly to brown it out. A cap solved his issue, doubt it will in yours.

Good points to ponder Eury. Thanks for the input. I'll try something different and let you know how it goes.

At the suggestion of a very knowledgeable Jeti Mezon user, I tried plugging one cyclic sevo at a time, to see how it worked. I got the glitch, brown-out, whatever, with every individual servo. I can't believe that one servo would draw so much as to cause this problem.

The other thing is that I didn't have this issue during the initial set-up and testing. I could pump the collective as fast and as long as I could with no issues. I went back to it yesterday and got this weird problem.

I also tried monitoring the amp load on the Jeti-box while moving the collective with all three servos attached and didn't see anything close to 2A on the display.

So, can I attach a receiver battery to the iKON, in addition to the SBEC on the Mezon 130 ESC? Will I have to turn the SBEC off somehow? Does this even make sense considering the output of the Jeti Mezon 130 SBEC? Starting to think I should go back to my old Castle and a receiver pack feeding the iKON.

If you are going to hook up an external pack you will want to pull the red wires from the leads going to your Ikon to disable the BEC. An RX pack will most likely deliver more current than the Mezon and may solve your issue. I doubt that the CC will do any better, I'd much sooner trust my heli to the Mezon than a CC.

Strange that you didn't have the issue during setup. What has changed?

Only change was- I reset the Mezon to it's default settings, and started the set-up over. I didn't see anything that might cause this, or solve it, in the set-up menu.

When you reset it did it go down to the default 5v (or whatever it is)? That would partially explain the issue. Bump it up to 8v.

Tried the SBEC at 8V- same problem. Tried it at 5V- not so much of a problem. It still happened, but not as frequently. Slowly bumped up the SBEC voltage and it seems that when I hit ~5.4V the problem really gets severe, and stays that way all the way to 8V.

I was running these Protek 250T servos on my TSA 700 using a receiver pack plugged directly into an AR7200 with no problem. The whole reason I went with the Mezon 130 is to get rid of the receiver pack and save weight. The Mezon SBEC feeds plenty of voltage into two ports on the iKON. I would think the iKON could handle the load too. If not, I would suspect that a receiver pack wouldn't help in this situation. Am I on the right track?

Don't know. Try plugging a 2s lipo directly in without the Mezon and see if it solves the problem. If so then you've discovered your issue lies with the Mezon not putting out enough amps for the servos.

The only thing I can think of at this point is if you have the wrong leads plugged in. The Mezon has 3 leads, 2 carry the output for the BEC and the 3rd is just for RPM sensing. If you accidentally only have the one with the second being the rom plugged into the power bus of the Ikon then it would limit the current the BEC could give the Ikon.

Also, is your Mezon the 120 or the 130 Lite? If it's the 130 Lite then the BEC isn't quite as high current. They only say it's 8a, where they say the 120 is 10a with a 15a peak. If that means the lite is 8a continuous or peak, I can't say, but if it's peak it's probably not powerful enough for what you are doing, but I am guessing on that since the specs aren't very clear.

I'm going to try the receiver pack and see how it works. It is a Mezon 130 RPM, which should put out plenty of juice for the iKON and servos. I've got the throttle and auxiliary cables running to the iKON, and the two wire, RPM cable going to the GOV port on the iKON.

I ended up switching to a CC Edge 120HV ESC and a 2S lipo. Things are great now! I just think the ProTek servos were a little too power hungry for the Mezon BEC. I'm actually using MKS 950s now and am very happy with them. Not as quiet, fast, or powerful as the ProTeks but suit my needs just fine.
