Nutsert or Rivnut. I'm guessing you stripped the threads on one of the side panel bolt holes.

You win Cd, right on both counts, except the threads aren't stripped, the nut spins in the frame. Luckily you can get to the back it from the other side, or it could be a big problem to get the cover off. This one rivnut always has been a little wonky. This is the first time I've ever heard of them. After a crash course on Youtube university last night, now I have a PHD in Rivnut technology, but no actual field experience, yet. I really appreciate Stealth using common fasteners, and bearings when possible, because that makes it s easy to source parts locally.
Yep, they are a brilliant piece of tech! I'm hanging over 10KG slung beneath my recumbent using them and take this thing down extremely rough terrain I didn't even consider on my Fighter and do moderately sized jumps regularly. Apart from a few of the the bolts working loose have had zero issues with them.
And now you know why I sold my Figher....this thing is so much more fun, weird and challenging to ride.
I didn't say I don't own a Stealth any more though.

I love that giant size battery Cd.

I just got a brain storm. Instead of removing my loose revnut, and installing a new one, why not just pretend I'm installing it, and tighten it down a little more?
Should work. And if it doesn't you can call it a brain fart.

Hopefully I get around to making a thread soon of what my bike has turned into and how my 72v63ah battery fits in the frame using 3 sub-packs in series with an external BMS.
I've got a 72v17.5ah pack in a pannier in parallel making the system 72v80.5ah total. Can push 300A peak from the battery and 600 phase amps from the kelly controller.
134km/h top speed.
A few days ago I got an inspection from Washington State Patrol and got a state-assigned VIN, and a license plate.
Insurance from SafeCo ended up being $93/year.

Got battery? Thats a lot of energy storage!
I could probably get just under a hundred miles on the SB Cruiser trike (about 60wh/mile typical usage) with that much battery (5760wh). (ATM I only have just over a third of that capacity in the old EIG pack, but it's probably less actual usable by now, over a decade into it's lifespan).
What are your packs made from?

All my packs are made from Samsung 35E's. I personally would knock them down to like 3.3Ah instead of the mystical 3.5Ah they're perceived to get in ideal conditions, which would get me 5465wh.
The main pack is 7s18p+7s18p+6s18p, totalling 360 cells, with copper nickel welding to support the current. Each series connection is 4x8awg XT150's.
The cargo pack is 20s5p, 10x10 grid for 100 cells. I have a second cargo pack that is in need of a repair (bad weld possibly), but if I was to fix it and hook it up, we'd get a total of 560 cells in the whole system, or 6650-7050wh depending on true capacity.
Any chance we can see how you've fit that inside the frame?

Here are a few old pictures when I built the main pack during last winter
Was before some various upgrades like the controller swap from KLS7230s to KLS8080h.
Notice how it would be impossible to fit them all in without them being partitioned. You have to get the bottom and top sub-packs in before sliding the middle one in like a jenga piece.
The 180A Cont. ANT BMS sits on the very top (I don't think shown in the picture, was just testing fitment in the picture)

I see how you fit that now....you don't have an actual Stealth Bomber...this is a clone. I was wondering.
That being said, this is still awesome and I would love to have it.
I 'think' I still have the record for largest pack build for a Stealth Bomber/Alpha at 3.25KWh with the 18S14P pack using Sanyo 3.5Ah cells I built back in 2018.
Cheers

Yeah 3.25kwh is a huge battery for the stealth bomber
nice! My 72v battery for my bomber “clone” was/is 2.6 kWh but will be building a new pack, maybe around 3kwh-ish.

This bike is very stealthy
I'm working on setting up a stealth clone and now shopping for front forks. Initial build will be low cost units from china. Wonder what the community here thinks about...
- Air suspension or springs?
- Upside down or not
- 26x4.0 rear tire; 29x4.0 front tire
Riding will be off road below 35 mph. Bike weight under 150lbs (maybe),rider weight 200lbs.
Below is a mockup with a standard MTB front fork with a 26 in front wheel.

what a massive battery, should be good for one trip around the world at least.
Can you share some details on how you did your foot pegs?

Forks came in, ZOOM for 29 inch rims. Seem to work but maybe no real damping, just springs. Works for now.
Will have to go with a 29x3 tire on the front since the forks only have about 3.5 inches of clearance.
Trying to get the head angle to about 67 degrees, similar to DH bikes I have seen. I'm at about 70 degrees in this pic. Might reduce the shock length some to try and get a little to get it close to the 67.

That Zoom fork is NOT something you want to use off road at pretty much any speed let alone 35 mph. There has been more than one that has broken while in use.
Be careful!
