-Too much weight -Electronics combo was overly complicated -Needed an on-board battery for the radio -Weak drivetrain -Was overall not fully thought out
What version 2.0 will feature:
-Much lighter -More battery power -Better, more efficeint radio setup -Tighter suspension -Stronger drivetrain
Progress Part 1:
Well today i revised the wiring on my quark 22. Bassically all that was done is instalation of micro deans and 2mm bullet connectors. I also wired the wired vertically to allow me to run a stock body (open wheel) when running with a 2 cell lipo.

Progress Part 2:
I finally decided to take my time and do a custom chassis the right way... I downloaded eMachineShop and with my experience from Drafting class i took last semester, i was able to whip up a 2D model of my chassie to be in no time. I printed it out in 1:1 scale (deselect fit to page on print menu) and taped it with 2 sided tap to a piece of 1/8th inch plexi glass. I then cut it out with a dremel and sanded the edges untill i was at the same dimensions i put in my pc. Then i made a screw digram on my pc and used the same tecnique to drill the holes, only i used a cone bit in the dremel to counter sink the screws for a smooth bottom. Then i cut up one of my many chassis' to mount to the plate and the end result was a plat that i could comfotable mount all my electronics without a problem. Not only that, but i eliminated a bunch of hardware and extra plastic, resulting in a dramatic 20 gram weight loss!
Pics:
In the mail right now is a set of 3racing rims and tires as well as cvd's (4's lipo's snap integy cvd's)
Progress Part 3:
Well I got everything in and running, and wow! This thing is balistic! Very stable at speed with the body... Without is another story LOL. I flipped it and snapped the chassis (hence the how2 on chassis building) Well I've concluded that this motor isnt enough for me... (only 95*F after a full 4s lipo run) so im going for a higher KV motor. Im thinking of trying out the new Turbo Ace motor. That with a 4s lipo would get me around 152440 RPM!!! Shoud have a new motor in a week
Pics:
Comming soon...

This is looking better but I think its going to still end in a ka-booom with all that power. Looking foward to seeing how your gonna make this thing better.

Thanks for the comments guys
MC201, it stayed together for the last version, so im confident that this one will be even better
First post updated!

That motor would explode before it even got to its full rpm at 14.8 volts...
yeah it would Be 151ish thousand rpms most BL motors have a limit of like 65k - 70k for rpm's 1/10 motors that is..... i dunno about small scale but i dought you could get it over 80k...

Maybe if you made a new shaft out of titanium and went with aircraft quality bearings...I'll bet you could engineer it, but I'll bet it would be expensive.

but can you magnitize titanium, becuase the issue is the nyodem magnets becoming debonded from the rotor (steel shaft) then you'd def. need the high end all ceramic bearings because heat can demagnitize the rotors if they overheat hence the don't run it over 200 thing... i think thats about true...

The titanium itself is nonmagnetic, however if you formed a rod composed of titanium or a titanium alloy; and then preformed a sputter etch cleaning of the surface of the substrate; and then did a hardening of the sputter-etch-cleaned surface of the substrate by plasma nitriding, plasma carburizing, or plasma carbonitriding; then you could coat the surface of the substrate with a magnetic material. The big advantage of the titanium, other than strength and weight, would be it's heat dissipation properties.
So like I said...expensive.

It's how they make magnetized titanium for super high fidelity recordings...I dated a research scientist for a while, she was nice, and really kind of hot, but crap did she make me feel stupid.

Pretty cool MTM...you made the math way more complicated than you needed to, but what the heck? You got the right answer, so congrats on two levels.
BTW,next time to save some math, the easier way is: 60mph=88ft per second. You had your rate of speed figured out to 66--2/3ft per second...you could have short cut there and divided 66.66/88=.7575 then just multiply 60mph X .7575 and you get your 45.45mph. I just thought I'd throw it out there in case your as lazy with math as I am and wanted a simpler way next time.

Ha, thanks for the shortcut!
Im always looking for them, but didnt catch that one (mainly cause i didnt know the whole 60mph=88fps)
