well today wasn’t wasted managed to time it right to try out @3DServisas push on ABEC pulleys - I’m so happy I refused to drill cores out to fit those TB screws in ones I have

This post is great. I have borrowed a lot of the parts list entries in my upcoming build Thanks sk8l8r!
@morty thanks but I can’t take much credit most things very much based on @Deckoz master evo

Progress
had to give up on my red bolts just a little too short using the 10mm neoprene foam
semi final mounting
reasonable clearance
wanted a little extra height on the focbox case, so used an x-washer
gives it more of a spoiler look. I ended up using 12deg wedge and thin Dooks short stack on the back and only a thick Dooks short stark on the front - feels really stable, I tried with the 6deg wedge and when I stood on the front of the board with slack truck bolts felt like balancing on a wire
still to make the cables look nice
@brenternet at full lean (trucks far looser than I would ride with) they don’t touch it just looks that way due to reflection I’ve tried to make them touch and could’nt
other direction
need to work out something to protect my power cables or get a stand
bajaboard meet clone evo… 
so just waiting on belts and push in ABEC pulleys
Looking awesome, it’s close but workable. I decided against wedging and I’m going to mount out the back, still got short mounts on the way too so that I can experiment.
Forgot to say just could not fit the switch in the end - just not enough space was looking for a low profile replacement but @Martinsp just released a push on with auto off function, going to use without switch on 5min auto off (will have access to pull the x90 from battery if needed)

Nice build. I have to say I’ll use it for reference when I continue my Falcon build. I initially tried the standard TB motor mounts, but couldn’t find a good angle for them. With the mounting positions available they ended up being almost horizontal. Which I know from another build to scrape motors, even with 107s.
So I’m considering the extended reverse mounts (or different mounts altogether). Although with 320-330mm 12mm belts, not having an idler is worrying.
I understand this entirely. I contemplated moving the truck back a bit by drilling new mounting holes but there’s not much room to go on the deck and I would worry about integrity. I didn’t want to turbo wedge either. I looked at about 15 different mounts, I have 5 sets of different ones sitting here in my box, none of them worked.
So I have some rear tb mounts in customs right now, released tomorrow and that will be my solution until something better comes along. I really didn’t want to rear mount but that’s just the way the cookie crumbled
Thanks for that input. I think the TB extended mounts will work, I’d rather have the motor clearance for full lean anyway. I just don’t know how much I trust 12mm belts at that length without a tensioner. Has anyone modded the TB extended mounts to have an idler? Or have different solution?
Found loads here in a search:
and many more.
@Static Further to this, here’s my plan:
I have a set of @dickyho dual idler mounts here, I’m going to steal one of the idlers from each mount and install them on the TB reverse mount:
I’ll drill out a little section of the motor mounting groove to give it some stability from sliding and then use a decent size bolt to put this idler on.
The idler bearings have a lip on one side and a nylon spacer, perfect for holding the belt in place but they don’t look like they are the best bearings in the world I’ll see how they hold up and replace as needed.
You can get them for $2.50, hard to go wrong really, even if its just for proof of concept: https://www.ebay.com/itm/302775190943
That’s a solid plan, I think I’ll pick up a couple of those too. Wouldn’t be difficult at all to mount those either.
belts
finally belts fit
removed receiver case for mounting in focbox case, wrapped in fishpaper
fit under here
not a bad fit a little tight when sealed
cut away a little plastic so the wires don’t get crushed on tighten
it lives…
this thing has brutal acceleration need to work on setting acceleration curve
so instead of that I decided to take my first test ride
wires need tiding (waiting on my auto switch) re-gripping still planned
and instantly found the same as @Static and @brenternet I’m going to have to lower my motors past the level where its sensible, I think I may go down the reverse mount route
@Martinsp my push switch arrived
@Kug3lis pulley arrived - really lovely quality!
@3DServisas really love the extra X washer thank you
@Kug3lis pulleys fitted, really like them
looks perfect from the outside too
I was expecting to need a 20mm longer belt (was on 280) but only needed a 285
had an unexpected side effect I was able to mount a little closer than before meaning I have workable clearance
I also more space between motors than TB pulley
vs
taken my first successful test ride kept under 20mph and best of all no motors hitting the enclosure!
strange feeling going from decks with tails, but like the way the evo handles so far
best of all when I look down I see my monkey 
by far the best best xwasher I’ve ever seen thanks again @3DServisas
still to add the push to power on switch but its finally usable 
Looks super clean bro
thanks, just got back from first 2mile ride, everything seems to be working fine so far can’t wait to see how fast this will go, but since I built it I really need to test it properly first he he
the monkey on the washer really does make me smile so much every time I see it a great touch thanks
Hey me too
What a sick build! Just curious, how high is the deck of the ground?
@Kug3lis I like that monkey washer plate! Is it laser etched on the anodized aluminum or silkscreen?
It’s laser etched
I’m interested in getting two gold ones , with one with Laser engraving on it, how much would it be ?
