I have more time (if it is the Lords will for me to be here) than money, so yes I'll wait. Oh yeah, Lepton came with a metal motor mount included in the kit too
Casey, we know U team guys have to order and pay for your stuff to but U must admit U will get heads up on stuff coming into the U.S. and therfore when it hits the shores U know about it before us non team members and no one is upset about that. You deserve and earned that spot on the team with your flying skills and knowledge and deserve every perk U get. Prime example, was that not U holding the new metal motor mount? and how long will the rest of us be waiting? Are U using the metal mount or the plastic one?

Motions:

Esprit price is not an estimate no shop post estimate prices don't you think ??

That's the MSRP , If Mikado decides to lower the price then Esprit will do that too.

The metal motor mount was no after thought, check page 23 of the manual. The ball should have been rolling on these mounts already. Most of the other upgrades are from the logo 10/14 so they already exsist.

I presume the quote about 'play' in the shaft of the Z30 motors refers to the fact that the outer part of the motor and the shaft are not retained but can be slid up and down, Gary Goodrum (and others) are insistent that as the load on the motor increases so do the forces holding it together. I have a Z30 on my 500 and I have stripped a main gear but this was only due to a speed controller that decided not to bother with the slow start - 0 to 2000rpm in 0.2S tends to do this. To be fair, when this happened with my Swift it stripped teeth straight off, the Logo moved the motor slightly out of mesh and it stripped the top off all of the teeth.

I feel that if a beginner can't build it and mount the motor to prevent gears from stripping, then there is a problem somewhere. Whether it's instructions, torque values, etc. anyone should be able to build this kit by the manual and be fully functional.
No arguement there.

An apology for not having enugh pinions would be nice as well

What we need is some one to step up from Mikado USA and state "Metal Motor mounts are coming and will be standard on all 3D kits sorry for the inconvenience..."
Willie, any delays in parts has nothing to do with Mikado USA. These parts are received from Mikado in Germany and if they are behind in shipments, we can only wait. The demand for the new kits and parts are tremendous and Mikado is doing everything they can to try and keep up. I don't think they expected this kind of customer demand.

Z Power motors are not the only ones that are built like this; I've come across it on Torcmans as well. I know all the experts say that motors with style of construction hold themselves together under load, but I've found that if you run them on the bench with no load, the can bounces back and forth quite violently at high rpm. Becuase of this I normally use a spacer between the pinion and the front bearing to lock it all together. In helis that use straight gears, a bit of axial movement of the motor shaft is unlikely to cause any problems, but it will place extra strain on the fancy new Logo gears. It would require some precise machining to make a spacer for use in the Logo as the position of the pinion on the shaft is critical. I notice that you can buy a Logo500 with Z Power motor direct from Mikado which implies that there is no problem with this style of motor construction.

I've had several motors in my 500, all of them "big", running on 8-10s and some putting out hairy amounts of power. My plastic motor mount is peppered with washer indents. Despite all the motor changes and excessive power, no problems with the gear which still looks new. However I would aggree with those who say that a plastic mount has no place on an upmarket, high performance heli.

Why don't we try using knurled locking washers? The would mar up the motor mount but also keep the motor from sliding.

NOw if they were to say put a 8 or 10 s system in the frame (made for it) the mod .05 would rip alot faster!
Willie, the mod 0.5 gears are not designed for 10S setups. That's why the 600 comes with 0.7 gears. Mod 1.0 gears would be really insane but I don't think you could do it with the herringbone design and keep the ratio within reasonable limits.

If I want to bin the herringbone idea and go straight cut then can I fit the Logo 14 200t main gear and if so is it possible to get a 19 or 20t pinion - oh and if so where can I get such a pinion as the best I can find is 18t,

I agree, this model is pretty much faultless and there is much about it I like, just want to get mine in the air

Tean,
I've run a couple of Z30 motors (a Century 600+ and the TT motor for the E550) up on the bench and the external rotor is rock solid with no vertical movement at all.

I was under the impression that one of the benefits of the herringbone gears was that it self centered so if there is a bit of vertical play in the main gear, maybe one less shim, then it would run fine.

Whatever, I've got over a dozen flights in using a Z30-1100 motor since replacing the main gear stripped due to the esc and its been fine, there's is no apparent wear on the gear or any dust around the gear or pinion.

Steve,
I haven't tried it with a Z30, but both the Z10s I did it with bounced above about 30,000rpm.
Glad your new gear's working out. No dust from mine either.

Why did Mikado even put a cheap plastic motor mount on the Logo 500 3D?

Even with the preferred metal or plastic mount, PROPERLY attached to the frame with the appropriate gear mesh. You can still produce "Gear Maggots" from the avoidable "IDLE UP" starts...

Who, what, when, why...in due time, it will still fly the same.
