It started with the deck. Couldn’t help to get this beauty which gave me the excuse to start looking for the remaining parts and basically start another build.
So this build was not a departure from my last build but pretty much an improvement (as it seems) on it. While it is also a kicktail + GD + pneummies approach, I wanted to try the Moon AT GD and Boardnamics BN270 trucks instead of 3DServisas which I tried last time.
Both Moon and BN are for me an example of top quality and affordable prices which is the kind of thing I’m interested as a builder.
This was also a very simple build in terms of extra components. No Davega, no lights, etc, just the bare minimum. It does have a battery capacity display though 
Riding experience
After riding this thing a couple of times I have to say it turned out even better than I expected. The bigger Evolve 7’’ tires offer a fantastic grip and confort. Also, this board is running on a 4.89 gear ratio with 130kv motors… the torque is f* unbelievable!!! I cannot give full power to this thing without doing a wheelie even with my weight all on the front.
Actually the setup is a bit extreme as I have a top speed of only 35 km/h. I’m loving it as I ride mostly in the woods and this baby feels like a rocket even on the steepest hills.

Moon Gear Drive impressions
Loved the simplicity and quality design of this GD. Also liked very much the fact that it is possible to remove the motor with the pinion in case one wants to swap it, unlike with 3DS GD.
Clearance with 7’’ tires is enough, would be great if it would be even smaller to handle 6’’ tires better.
The sound is amazing, I tested it with no lubing and it seems like a race car. It’s crazy compared to 3DS which is totally silent.
Only problem I had with this GD was that the fixed holes for 9T had too much of a backlash. Was not a big deal as I could tune it well with the adjustable slots.

Deck
Used Lucid clear grip spray to preserve the beautiful art work of deck. Because I used the heavy grip variant, it was difficult to make it stick so I had to use a lot of glue and a brush instead of just spraying it as recommended.
Filled the wheel wells with wood putty (thanks to @Riako for the tip!), to recreate a flat surface for the enclosure and avoid water ingress. This allowed to move the enclosure more to the front gaining more clearance on the back between the motors and the enclosure.
I used the battery capacity meter design by @chberne along with this meter.
For the risers I designed a slightly angled riser with tunnel. Can share the design if someone is interested.
Enclosure
The enclosure is from @EboardSolutions. Those “giant washers” are brilliant and were created also by Frederic. I though about adding a fiberglass reinforcement on the ABS enclosure but ended up not doing it, in the motto “don’t fix what it ain’t broken”. I want to find out if it handles the weight just with the help of the metal strips.
To seal I applied a Crown rubber strip SRS136 15mm x 8mm om the enclosure and 10mm foam on the deck. Made the holes first with a punch tool, very important.
On the front installed an XT30 for the battery meter and on the back there are two MR60 for the motor phase wires. All fixed with epoxy.
For the sensor wires I didn’t have space for one of those 6 pin round connectors which tend to be very long, so I ended up using a junction box gasket. Made a 4mm hole first with the punch tool.
Motors
Made extensions cables with MR60 connectors and added 13mm PET braided sleeves for cable protection.
Because these motors have an open can I used 3d printed covers from @Pryside. Also used a bit of silicone on the wires hole. The phase wire PCB is already conformal coated so I didn’t do nothing there.
Hangers
After I fixed the stock BN axles with green loctite I realized they were to short and had to take them out. I got them out with the help of a propane torch and used 10mm shoulder bolts with 90mm length as a replacement.
Got 10mm spacers: 12.5mm long between GD and wheel and 22.2mm long for the Rockstart II hubs.

Many thanks to @b264 for the waterproofing ideas, @Athrx, @ProfoundMagician and @Minimadness for the help with the shoulder bolts workaround and the vendors and users of this great community for all the help and inspiration.
