Interesting. The Hobbywing ESC that has become popular for use with the vbar governor has this extra programming lead. I wonder if it has a similar output?

I guess it's a different firmware, to output the phase pulse for a ESC is very easy, super simple change, but it's not normally done since there has been no need.

I fly another brand prototype that has same function, so I suspect we will see this on several ESC's

Performance is zero difference from using an external Hyperion phase sensor though (tested both back to back)

Does anyone know anything about the Hacker Master Spin 170 Opto Brushless ESC or the Hacker Master Spin 220 Opto Brushless ESC? Would it be a good choice for the XXtreme?

Just wondering (I asked something similar before) is the model completed testing and now its just a matter on manufacturing the parts etc and getting the kits out??? I understand that its in the companys interest to get the product out the door etc but (i hate to name names) certain companies tend to for whatever reason delay for really really long times, they even advertise a certain FBL head for over 1 year and its still not out yet. I must admit i have no experience in being RC helicopter manufacturer but i would like to think initial estimates would be fairly accurate.

Good question Maybe Dave can answer. From what I can tell the parts on the XXtreme that appear to still be prototypes will probably be made from the plastic material that Mikado makes there parts from. If that's the case then they are probably making the plastic injection molds for those parts (that's one thing my shop makes injection molds) this is only speculation it just makes since. In the mold making business you want the parts to be right when you make the molds because the are very expensive and very hard to change after the fact. Its very common practice to make prototypes out of aluminum or other materials first to prove them out before you make the molds. Once the molds are made its game on you can pump out thousands of parts a day. Hope this helps.

Oh one more thing look at what happened to Efilte (blade grips flying off in flight) and the blade MCPX a very different heli basically a toy but... Not only did they have to pay thousands of dollars to fix the molds they also had to send out hundreds of free parts pay shipping and more. Something that small cost them allot of money and hurt there reputation. So I would guess that once any new parts are added to the XXtreme after the fact the Kyle has hundreds of flights on it you can bet they will do allot of testing again. I applaud Mikado for this approach even if people are upset because its taking so long in the end you will get a quality product that's proven to withstand the beating that Kyle can put on it.

Quote, "in the end you will get a quality product..."

Looking for any excuse to discuss what I can about the XXtreme, here's some info on one aspect of the design that might lend itself to the "quality product" deal.

The oldest XXtreme we have has just a few flights short of 200 now, and I decided it was time to check the motor bearings.

So after unpluging the three ESC motor wires, and without having to turn the heli up-side down or on it's side, it took a few seconds short of one minute to completely remove from the heli, the motor while still on it's mount, including the counter-bearing assembly.

And then the way the motor and mount go together, you don't even need to remove the motor from it's mount in order to service the motor bearings or shaft. Very easy and quick.

BTW, the motor bearings on the Scorpion 5035 were fine, just cleaned things up, and put it back together. On the other hand, the CB bearing was pretty ragged, and that got replaced (same bearing as the radial bearings on the blade grip of the Logo 600). It was an easy "tap the old bearing out, and tap the new one in" affair. Again, very easy.

It would be easier to understand with a picture

Yep (-: I hear ya.

But here's another quote from the same post, "...to discuss what I can about the XXtreme..."

I doubt you'll see any "up-close" photos or detailed descriptions of the motor/pinion arrangement before production models hit the market. The copy artists are lurking everywhere, and it's soooo much easier to just steal an idea, than to innovate on your own.

Do you have to re adjust the gear mesh ?

If not I know how it's mounted or at least I have another solution.

In my own heli the engine mount serve as a frame brace/pinion support/engine mount. Only 2 screw and you get the motor along with the pinion. the pinion support is tied to the the mainshaft bearings as well. my gear mesh dont move more that 0.0003'' fully loaded.

the pinion support bearing can then be removed without any further dissasembly.

On re-install, the bearing support bearing did not move and gear mesh is still perfect.

I told more than enough for smart people to figure how I did mine.

sounds about like mine in my trex Xtera 700 , 6 bolts and it slides right out. very user friendly , the oneway in mine is in the second gear! Hirobo shuttle Zx oneway that has no scare marks on it yet in 2 years .

Question: "Do you have to re adjust the gear mesh?"

Yes.

The pinion has to come off the shaft no matter what when you service the motor. And with herringbone gears, when it all goes back together, the HB pinion has to be adjusted vertically to the main gear, as well as the "traditional" setting of the backlash.

So there's really two "adjustments" when it goes together.

Mine is much more simpler. but this is the general idea

I forgot about herringbone, In that case I would need to adjust axially but radially altough it doesnt come back exactly at the same place (nothing come back at the same place after dismantling.) it is so close and it does not justify to re adjust radial backlash.

Question, "Any new vids???"

We are going to be laying low for a few weeks, not doing much "testing" or "promoting", while Kyle preps for the XFC (June 3,4,5th).

I'll leave with this. The mechanics (the head and its dampening system, swash plate, main and tail gear trains, frames, battery mounting system, motor mount system, tail control system, tube drive etc...everything mechanical), has been proven, even with 14S power and big 800 class blades.

As of last night, we've logged 308 flights on three XXtremes (mostly with two of them, one with almost 200 flights on it, and the third has only 11 flights on it), and are prepared to say the mechanics are ready. You can rest assured Mikado has done their homework on the mechanics.

10 amps of BEC and high quality HV servos are handling everything Kyle can throw at it (again, as an 800 on 14S), no problem.

V-Bar. What can I say. It works.

Scorpion 50 series motors are handling the power needs nicely. The massive bearings and shafts on these motors are holding up just great. No issues.

Blades. I'll give this warning...and listen-up Stay away from 800 class blades that have NOT been recently designed for aggressive 3D flying (if that's what you plan to do with the XXtreme)...meaning the blades are too flexible, and just designed for AP work or less aggressive type flying. The XXtreme is a radical departure from previous 800 helis, and the amount of stress it can put on blades is enormous.

The two most common battery capacities in 14S we've proven to give good flight times (based on how you fly), are 4400-4500mah, and the 5000-5100mah sized packs. There's been talk of larger 6000+ packs with an "800 class" heli. I don't think we need to go there.

And, the perfect ESC for 14S power is? Hmmm...

What Heli is Kyle going to fly at the XFC ? XXTREME
