SHIT YEAH! Can’t wait to see this come together!
After a bit of hunting around I settled on this HV Step down adjustable switching regulator to power my receiver and ESC fans. Not a lot of options at 14s… but this little switching regulator (converts voltage in little chunks rather than just wasting energy as heat) looks sweet
After reading around a bit on the heli forums and what they do to maximize Tx-Rx reliability I decided to grab a bit more Scorpion swag, a: Scorpion Back Up Guard.
basically it plugs in to a the low volt Rx circuit I’ll run at 6/6.5v, and if it ever runs down to near 5v it will kick in and power my Rx & esc fans. So it helps with BEC brown outs as the heli boys call them, inductance induced BEC supply issues and BEC failure…
I’ve been hunting around now for a while for a solid high amp connector solution, especialy for my 2 x 7s battery leads (14s) that I expect to get hit with around ~280 amps of current. 6mm xt150’s are not quite up to spec, or even the 7mm AS150’s are only rated at 200a I see @Nowind just got rid of lots of his xt90’s on his 80mm Leo board…
So I’m going to give these a shot instead
Solid 6mm connectors from LMT rated at 400a… & when LMT say it’s good for 400a I trust them they are
Likely the cheapest performance mod/parts I’ve picked up thus far, maybe I should have got them in gold ?
essentially they counter balance the valve stem from inside the tube…
Looking forward to a update on these. I use modified counterweights for cars, self adhesive but they come loose after a couple of hard rides.
This looks like a good option, If it actually works
great build. Love the scorpion motors. I had a bunch of them when I was a 3D RC geek back in the days. They are massively powerful. I wanted to do some build with them but these are getting expensive. Nice move on the beads. Really wondering how you can put that into a tubed tyre; you need to remove the valve right?
I’m guessing just removing the schrader pin and getting them in there.
yeah that’s it bro
Scorpion have some motors on discount atm specifically this S-5525-170KV for $160USD would make a great duel 10s vesc 4.xx build without being crazy in price. It’s kind of the little brother to my motors
you just need to swap the motor shaft around
Thanks ! Maybe I’m not doing it right but this does not seem super easy to do, is it ?
How did you go @okp? You work it out…
You need to remove some little grub screws, pull it apart, press out the shaft (I used a drill press, a arbor press will work to). Then re-assemble in reverse with the new shaft. I bought new 8mm shafts from Scorpion. You could use the old shaft or even make some from 10mm drill blanks. Again all the info needed was in the above links.
I used scorpion motos for my first build, and will use them again
Yeah @Dornacht I wish they had a few more of their bigger motors in wind your own kits, I would like to try my hand at that. Which motor did you use bro?
The 5030, going to be sending it in for warranty, because its discontinued I will helpfully be upgrading, if your keeping the threaded shaft, I did, I would suggest getting a nylon locking nut made out of steal vs the aluminum one
Nah I used a couple of helicopter shafts, I linked them above.
BTW about the balancing - i’ve noticed mountain board tires have a thick spot in one point, you can find it by pressing on the center with fingers. If you position the valve opposing that spot, it gets a lot more balanced.
Hey man, is the thick spot you mentioned here super subtle? Checking a couple different tires I have (both Trampa and MBS) and I’ve been unable to find it.
thanks, I was referring to the micro ceramic balls. would love to get some photos on how to put them in the tyre
Easy @okp This vid shows you how to remove your valve core and even make a tool if you do not already have one, sometimes they can be found on a bicycle multi tool for example. Once the core out is out pour in the beads through the valve stem then replace the core and fill the tube with air
I made a small paper funnel I masking taped to the valve so I didn’t spill any why I jiggled the tube about to accept to beads
- you don’t even have to take the tire or tube off the rim
