That’s a good question, I’ll weigh it next time it’s off the board
Ok, I’m back on this! Finally the end of the Aduilting tunnel is approaching and it’s warmish and the next few weeks are just crying out for me to road test this baby.
The only change I made was that I swapped the lower spring plates, which were 2.5” wide by 6” long and 0.064 thick (read: really thick) for new plates that are only 0.032 thick. I left the 064 upper plates, which I think are 1.25” wide.
Jumping up and down on it seems to be about right. So what I need now is a nice gravel road and less rain.
As you probably don’t recall so far I’ve only done the front. The back, which includes motors, etc. is still a rigid MTB truck. My plan is still to install the cannibalized EcoMobl motors on the rear. Not sure if they’ll have enough poop in them to drive it since the original ecomobl was awd.
I also found out after being soundly routed recently on a very steep trail by a couple of yahoos with 18s boards (you know who you are 
) that I need more torque if I’m ever going to show my face in California again.
So i have 3 choices. The Ecomobl motors, the original 6374’s ooooooooooor
I’ve been looking for an excuse to deploy these ridiculous things which I bought on a whim
and will fit…
But first I better work through embiggening the battery

@glyphiks I finally remembered to check the weight. They come in about twice the weight of the outgoing solid trucks

Holy shit! it’s ready for testing! Unfortunately life is getting in the way for the next 2 weeks so I won’t be able to so much as turn it on until the end of May 
One of the major changes I made was to go from 10-32 bolts for the assembly up to M6’s. I think the larger diameter (2x probably?) will hold together better. In the long run I don’t think screws through holes in the spring steel is going to work because there’s just too much shear stress. Probably for the next rev I’m going to have to waterjet custom spring steel plates with wider ends than center and maybe do some fancy work with the mount points like have steel sleeves or similar.
I also think I need to crank the mount angle up another couple of degrees to get more aggressive turning
Also I got this cute little board for my grand-Niece. She’s 4, I’m hoping she’ll grow into it.
I need to laser some of my signature bigfoot stomp pads for it before I give it to her.

first field test complete!
Overall I was really happy with the way it handled small to medium rocks - it’s butter smooth across trails like the one in the picture.
However, I definitely screwed up when it came to the amount of turn I gave it - way too little. I think that it will be pretty easy to modify it because I don’t think there’s a lot of benefit to having the spring plates so far apart. If I move the upper plate closer to the lower plate by, say, 1/2” won’t change the suspensions ability to dampen but will give me the proper amount of turning angle
That, however, involves re-working several blocks of aluminum that I would have rather not had to rework.
But overall I’m super pleased and happy that it worked at all.
