Seems like I recieved a letter from bpost (belgian postal service) this weekend which said I had to pay a certain amount of import tax in order to recieve a package. the mail however didn’t specify anything about the package. (place of origin/tracking number/cender). All it said was to pay the amount before the third of march. It only came into our mailbox on the 5th of march however so even iff I knew where it was comming from there was no way for me to pay on time. I am guessing this is for the parcel with your drives. I checked my mail again and I didn’t recieve any mail regarding the parcel neither can I find any information (no tracking number and only shows the delivery adress.) when going to the supposed tracking site linked in your mail specifiing the order confirmed. From what i can gather the parcel will be shipped back to you after failing to pay customs on time. I honestly wouldn’t realy mind having to pay delivery again if the drives would the be shipped via dhl which I have had a much better experience with.
ps: sorry fro the long somewhat ranty message in your tread.
Hi,
I have some issue with my Moon gear drive.
For the second time I broke 3 teeth on my gear, but not on the same side
My setup is a 9" MTB with 100kv 6385 motors, 16s 70A per side and 5,5 ratio.
My backlash is perfect (20 years in R/C cars).
The first time, the bolts that hold the hub plate to the gear were a little bit loose.
My conclusion is that it created a small misalignment and it snaped under load. Helical require more precision than straight cut.
Moon was kind enough to send me a new gear for free because I explained him that I followed the instruction that says to not use loctite nor over torque.
I replaced the gear, I used loctite and more torque on the same bolts with a bearing inside the hub plate to improve the support and the correct amount of shims to be flush with the hub plate (most important point when you assemble those GD).
I did everything to make it bulletproof (well, that’s what I thought…)
I was on a trail, at around 10kph and suddenly, on the top of the climb, after my back wheels took off from the ground for 0.1s at slow speed I heard a snap when I “landed”. I was not full throttle, my wheels didn’t spin like crazy at all before hitting the ground.
Needless to say that i knew exactly what happened…
it is a quite strong material for gears, (running 190kv, 12s 120a each side) but sudden impacts causing the wheel to stop ‘instantly’ will just blitz the teeth
I had similiar problems. Now my drives sit in a box and I went back to belts.
8" tires. 12s 8p 190kv. Shredded those things. And the screws to the hub pate rattled out…and stripped…and ultimately dead. I got little to know help via email.
I replied to every email (16 in total), offered a solution, (you ignored it and decided to order random parts from the site), offered to call but you didn’t have WhatsApp/Telegram…
Good to hear everyones experiences, good ajd bad. From my experience @moon has replaced any geardrive issue ive ever had, and iver ordered like 5 sets now over the years. He reaponds like immediately and problen solves because he actually cares about improving his product. Ill he running 18s 5.5:1 ratio in 135kv prolly 120a/motor soon here on his batch 7 helicals, which will be torquey affff. Keen to see how the gears hold up
Obviously parts can have issue from manufacture, but straight up had moon reply at like 12pm after a drunk messaged him about an issue, absolute beast of a designer and got top notch customer service, @Venom121212 is crazy how high max current can get, even on a ‘chill’ ride
@moon, could you add another set of threaded mounting holes on the truck mount clamp, to increase decrease the available (min) adjustment angle?
On matrix 2s on a haero (30deg tip angle i believe), the highest you can get 6374 motors is about level with the hanger. One half step/rotation up would be ideal, but the next set of holes makes the motor can hit the matrix top truck bracket during tight turns.
