Limitless Mr.Duke’s Limitless Build

[Notorious J]

There’s plenty of room there. I can torque the wheel inward by hand with moderate force and still have clearance.
If for some reason it’s ever an issue I can always revise the program and cut new trays within minutes.

No disrespect was ever intended @Mr.Duke. I know you would have taken all considerations when making the design. I was just remarking of how tight the area was in my own ridiculous Notorious J way. Less angles equals smoother air flow. I'm not worthy.

Oh quit kissing a$$

I didn’t take any comments in a negative way.

I appreciate y’all’s feedback good or bad.

Watching with interest...

Let me know what you think of that spool, thinking about getting one for my Typhon build.

 

[Doom!]

Why is it, that once this is up and running, I envision half way through its run, one of those shock rings like you see on a fighter jet appearing!

 

[Mr.Duke]

Finished the battery trays and got the spool installed. I had to rob 2 Velcro straps from my 6s rigs while I wait on 2 new ones to come in the mail.
Very pleased with how the trays came out and the quality of the FP Pinocchio spool and driveshaft. Spins so smooth and the tolerances are absolutely perfect. Zero wobble in the driveline now, but you will have to clearance around the rear chassis brace ever so slightly to fit.

Next on the list is to solder on XT150 connectors for the looks and switching out the stock droop screws for some longer smooth domes as I’ve maxed out the length on the front end

I'm a bit confused how these long spools work.. surely having all that amount of shaft hanging out back with no support is just as bad as having an extra long driveshaft just like stock..!! or am I missing something ?? surely it must oscillate like crazy

The custom spools have a 8mm shaft, guessing the thought is that you aren’t bending that!

My battery trays are at a very short distance from the wheels just like yours and never have a problem with them.

But the Scorched center drive shafts are 8mm, ( have them in my Infraction ) so I still don't see what the benefit of the Pinocchio shaft is

3 medium length shafts, instead of 2 short, and 1 really long one!

I decided to go with xt150’s on all my stuff, I’m glad to see someone else using.them also. I’m just back into the hobby again since Jan 2021. Are the xt150’s durable over the longer term?
Build looks great

Also, the center (Pinocchio) is a fixed point(fixed withing bearings) that can only rotate. The dogbones are only held up in the air by 2 (a-sync/torsion creating) cup's. The longer the dogbone the more difficulty it has dealing with the torsion, that's what causes the wobble.

I don’t know how to really answer this without going geek mode.....

Any rotating solid shaft has what’s called a “critical speed” where the shaft will deflect at a given rpm and cause the shaft to bend away from the axial centerline in a harmful way to power transfer. The load, diameter, length, balance and stiffness of the material the shaft is made from, will ultimately determine the rpm that this critical speed takes place and we get harmful vibrations and wobble or complete shaft failure. Increasing the diameter of the shaft, stiffness or reducing its length will almost always increase the shafts rpm where this harmful deflection takes place.
By lengthening the spool, the stiffest part of the assembly, it also shortens the driveshaft at the rear which raises the rpm at which that shaft reaches critical speed.

Nice build Duke!

You are referring to these? I guess it’s personal preference. What I do know is, the stock rear shaft warps easily. Mine is bent, even with the new center shaft support on the V2!

wow is that and XLX2? I got one for my Kraton EXB 6s but it didn't fit lmao so I got one of the last Mamba Monster x 6s available.
