whats up to all

so yeah im the guy that won the grand prize at ircha which if you didnt know was the 700 plus vcontrol , anyway i was out today hitting it hard and by no means am i all that but i can fly decently hard when all off a sudden pow no tail started to spin down it came on a forced auto, thankfully nothing else broke. now when looking at it i striped the tt gears in the front gear box . now is this a common thing or a fluke? any insight on this would be great
thanks
joe

Nice save.

I've got close to 100 flights on mine. No issues knock wood. And, I haven't heard of anyone else blowing out the gears.

I only adjusted the agility slightly from the box stock logo 700 preset. Did you raise any of the stop gains on the tail and/or do you do a lot of hard reversals? That can take its toll on any gear train.

if it ain't broke, break it.

700 tail

yeah nothing to hard i do do a lot of spinning on the tail i do some fast inverted pirouetting circles but i would not suspect that i wouldnt think but i do fly mostly nitro with one other electric which is the align 700 dominator so maybe just a fluke? i am super excited to have this heli flies solid precise fast i just dont want to have to auto this again that way lol

Tail gear failure again

Put in new gears 4 flights later while inverted stripped again in it goes could not save it this time there is definitely something wrong with the tt gears the bird is not in bad shape but definitely expensive to fix

Was it the front or rear set that went each time?

On my first 700, it happened twice and both times was the rear set in the tail case. My first was was during a piroflip. Managed to auto down and save that one. Second one went while inverted just doing a slow flip. Didn't have enough altitude and wrote it off that time.
Bought another kit and shimmed the crown gear in the tail case. Also started using DryFluid Gear. No issues since (~100 flights). <knock on wood>

Both times it was the front. I'll be quite honest with you it is a nice heli and I was getting used to it but that should not happen I fly align helis and my 700 dominator gets absolutely abused with no issue I baby this one and boom two times it blows the gears I believe there is something wrong especially with the first time being that the Mikado guys are the ones that built it they literally build these things all day so I don't know

What does Mikado have to say about it?

Or Mikado USA?

Have you asked them?

Yes I believe we have resolved the issue. According to Ron with Mikado the gear mesh on a logo is 0. That being said when I put it back together and put in a little "wiggle" between those gears is positively wrong. The method he had mentioned was to assemble the bevel gear on to the bearings fully then assemble to the heli then using a tool insert in the end of the tt housing and push the bevel gear in until there is zero mesh between the gears . It is undefined in the user manual to this method and also let me know that the use of dry fluid is unnecessary as long as you have the zero mesh and that goes for the rest of the gears on that heli. Mikado USA helped me out with replacement parts and with that thank you Ron and crew at Mikado USA you guys are a class act and I appreciate that as for the heli it's back up and running with three flights on it when the weather breaks here in Cincinnati we will put on some more and hope for the best

Excellent...that's why I like Mikado USA and am a many times repeat customer.

I'm planning on getting the new 700 Logo, too!

What motor and ESC are you using?

Haven't heard of them, yet?

Does Mikado USA have them?

Never mind....lol

Just checked at Mikado USA....

I've been using MKS X8 servos, which I been very satisfied with.

But, having checked out these Expert servos, I really like the idea of the quick release cables.....that is really slick.

Great speed and torque specs, too....

I'm a fanatic for having neat and tidy wiring harnesses and the quick release cables would allow the wiring harnesses to be fabricated/fitted independently from servo installation....allowing for even neater cabling.

I'm sold....

What type splines do the Expert servos have?

JR, Futaba, or Hitec....want to get the CF arms that can be had with the 700 combo....

Thanks

I really do like the ability to custom fit the cables. But one point of caution, all the wires are black, so you have to be careful to insure your polarity is correct after you are done.

As far as the splines, mine are Futaba.

Detachable leads are neat....and also one more failure point.
I'd also be curious on the durability of the Expert servos. I've had a bad crash and a couple not so bad crashes on my Logo690sx, and a write-off of my first Logo700.....and I have yet to do any damage to the X8 servos I'm running in both helis.

I agree that there is a possible failure point, but then no more so than plugging them into a FBL controller. If there is no strain on the wires, and the plugs are secured with hot glue or something similar, I don't feel that there is a much larger failure point than using standard servo leads.

Thus far, I haven't seen any durability problems on my R2 servos. In my setups, I utilize the short leads first and save the long leads for when I switch to a different setup. This gives me just an extra set of leads to use.

That's good to hear. I actually considered them for my Logo700. I already had one set of MKS X8s in my 690 though that were flight (and crash) proven. I decided to not add another different brand into the mix until the X8s give me a reason to do so.

I've had great success using MKS servos on my Logos....brushless versions.
