Every build has it challenges. This challenge was seeing if Abec 11 Flywheels 107mm could be used with current bolt-on motor mounts on the market. The answer is a "yes" with some modifications to the truck. Using Torqueboard motor mount and Paris 195 trucks, some of the casting has to be removed in order for mount to sit back far enough for proper pulley alignment. We'll see in the future if this becomes a problem. Second problem was because of the offset of the wheel a spacer would be needed so that the drive pulley face would sit flush with back side of wheel. Luckily a machine shop close to me, made me a set of spacers out of aluminum for $65. Now that the unknown part has been done, the rest of the build should be pretty straight forward.

Thanks. Getting pretty good at making these wood enclosures. Only one try this time. My first build it took three tries before I got it right.

The wheels each weigh 1.35lbs with bearings and spacer. These wheels really have a bouncy feeling to them. I accidently dropped one of these wheels on the ground and was amazed at how it bounced around like a ball. No doubt when the deck is finished, its going to be no flyweight.

how are your custom wood cases take the flex of a board? i would expect it kills off any flex and the connection of case <-> board is under a lot of stress?
looking forward to hear feedback about the giant wheels. probably its an awesome floating feeling. the only issue I have with those is, that the "elegance" of a longboard is down the drain with these bulldozer style wheels. :lol: was thinking about 83 vs 90 vs 97 vs 107 myself - kegels were too small for my taste, but I just couldnt go bigger than 90! I was also suprised how heavy the 90mm wheels are already :?

Ahhhh the bottlenose drop through...My favorite deck shape. Nice to see it mounted drop as well!

Sweet build.. Those 107mm's must be pretty big. 97mm is a bit big but will probably try it to see..
I just recently got these MBS 100mm All Terrain style wheels - http://shop.mbs.com/accessories-486/mountainboard-wheels/mountainboard-tires/mbs-all-terrain-longboard-wheels.html
Haven't tested them yet. I wonder if they'll decrease distance.

You are correct, the enclosure stiffens the board. It pretty much takes the flex out entirely. The enclosure is screwed and glued to the board. Whatever stresses there are it should hold up with my 170lb frame. This is my third build using this method and the enclosures have all held up without any problems. The only problem is the wood lid to the enclosure gets marred up from small rocks, debris ruining the beautiful finish

Well, the board is pretty much done. Bench tested and everything seems to be working as it should be. Waiting for some good weather for final test. Have to say this diagonal dual set-up took a lot of time to wire up. Didn't help that I added accent lighting, voltage display and fans. I would say I've got 5hrs into the wiring. Although this build was still fun, I've got to admit I need some new challenges.

Those fans are nice Do you think they help?

I think you need "air inlet" holes in your enclosure if the fans pull the air out of the enclosure...
EDIT : Oh I see, you left some wiring holes unused, so they should act as such
How much does that thing weights ?

Don't know if the fans help on this build. They should help .I do know on my previous builds, on 90 degree plus days the esc can reach a temp of 140. With the fans the esc temp will drop to ~115. Temperature is measured at the heat sink with an IR thermometer. I am aware that a lot of people don't have a fan cooling and they seem to be fine. The only conclusion I can think of is the wood enclosure traps a lot of heat inside. Surely it doesn't hurt to have cooling fans. I just wonder why your typical 6S esc have a fan. Probably because the sink is not large enough to dissipate the heat. Now you got me thinking. How hot does a 6S esc get on 90 degree days? Something I'll have to find out next summer.
As a side note to anyone using these brushless DC fans, I found two problems that occur. The first is the fan blade may come apart from the shaft. The fan blade is pressed fitted onto the shaft. If you ride a lot on sidewalks, the jarring causes the fan blade to come off. When this happens reassemble it with a drop of crazy glue. Have a fan guard installed helps to catch the fan blade when it comes apart from the shaft. My first build I didn't have the fan guard and lost the fan blade. Had to order another fan.
Second problem that may occur is the fan blade may break off at the area where the fan is pressed onto the shaft. Found this after some sidewalk boarding. The plastic is too thin around that area and tends to break from the jarring. My fix was to use some epoxy around that area. From my pix you can see a dab of epoxy at the center of the fan blade. Seems to be working fine on my other builds.

I would think a dual diagonal would corner better too with better weight distribution. I find that the rear end of my board washes out very easily with a dual rear setup.

You are able to run longer motors with dual diagonal, because you aren't restricted to fitting two on one truck. That being said, if your motors can both fit in the rear, I would go that route because it just feels more balanced (in my opinion). There will be people who say go dual diagonal every time, and people who say always go dual rear... it is just personal preference, because they feel different when riding.
as for the disadvantage, I'd say uneven braking is probably the biggest. But again, it's all personal preference.
