There is also the Proxxon micro mill.

...signing in to follow this one :D Gotta love the CandyMan :D

crazyjr 03.19.2009 04:23 AM

Candyman, I have run two low kv motors on lower voltages. I have a 1200XL basic lehner, in an RC10GT conversion, that gets run regularly on 5s lipo's (rough equivalent, maybe slightly lower volt as you are planning) geared to about 40, it runs cool all day and i can get away with smaller cells. I also have played with a 2250/10t (1184kv) lehner on 4-6 s lipo's, it's in a twinforce with a center diff, buggy gearing and a 19/51 pinion to spur. till i broke a C-hub, it never had trouble pulling the truck on MT size knobbie tires to 50+, with wheelie power to spare almost everywhere on the trigger i wanted. What i'm saying is do not discount the 2y Just because its a low kv motor, If its like my 2.5d (1600kv) it has almost as much torque as the 2250 i have and should be able to pull the required gearing

Candyman2 03.19.2009 06:14 AM

oh yeh, im not writting it off because its low kv alone, its rated for 50 volts i think, so it stands to reason that the peak of 2500 watts will be achieved near that. At 22 volts i'll be getting much less power, more like half. I might do better with a motor that has a peak voltage at 25v or so.

I will test it this weekend, I have it geared for 44mph (20/44) but if it doesnt feel punchy enough im going to switch to the medusa 80mm 1600kv.

Aceldama 03.19.2009 09:00 AM

Thanks for the information on the mill that you use. Now I can spend all day reading about how to use one, and then try to convince myself that I need one, then convince the lady that I need one. Thanks again.

crazyjr 03.19.2009 09:48 AM

Good to know that you are not giving up on the motor, with truggy diffs it should be good. BTW I like the hot rod picture next to the mill and lathe

That looks awesome.

Takedown 03.20.2009 11:53 AM

Looks sick man! But holy hell thats going to be a brick.

suicideneil 03.20.2009 08:49 PM

BL brick, the best kind :yes: :mdr:

Funny, I swear you said you wouldnt make custom chassis once upon a time- but people would pay good money to own ones like that, just look at the Maxxler chassis....

BitHed 03.20.2009 09:23 PM

Brilliant!!
 
...oh yeah :D Thats EXACTLY the kind of finish i had in mind when i made THIS lol...

...makes you cry doesnt it lol...

...btw this picture has been banned from being shown to elderly people and small children...Lasting trauma apparently :whistle:

Very, very nice candyman. You really are the candy man, you supply candy to my eyes. :smile:

Serum 03.21.2009 03:25 AM

Great work Ryan! Haven't checked this thread for a few days, and look what you've created..

One fine looking lightning, the best i've seen so far! and it's not even finished yet.

Knowing both you and your skills I know this will be another jaw-dropper.

(check out his site, the airsoft guns he makes are from another world) the patience and skills are incredible

Is there any way we can help you overcome your lipo-fear btw? I know a good counsiler.. (kind of a cyclops, a truly great guy)

Candyman2 03.21.2009 09:14 AM

Hey guys, thanks!

Bithed, im just a PM away if you want a quote :)

All gone together rather well, first gentle run was surprisingly good, it felt a bit flat in my garden but out in the open it does actually move rather well. I didnt expect theis motor to work well on this voltage but its fast, no other word for it really.

Ok, now to the shell, lsp shell is a bit hard to find so I bought a Proline Crowd Pleazer for a kyosho ST-RR, I just need to jiggle the body posts a bit.

hemiblas 03.21.2009 09:55 AM

Wow thas just plain awesome. If you are going to keep nimh 18 cells is the way to go. I would hate to see someone try this setup on only 12.

Serum 03.21.2009 11:19 AM

very nice Ryan. you got that aluminium from Chronos?

The only thing you might want to change on that setup are the shocks/ shocktowers. there sure is some room for improvement on the stock suspension

Aceldama 03.21.2009 11:29 AM

That is a work of art. Excellent job.

BL_RV0 03.21.2009 11:40 AM

Beautiful.

MetalMan 03.21.2009 12:18 PM

Nice work! Turned out excellent, especially considering the crude initial cuts :lol:.

Only thing I have to add: be careful with those tires. A buddy of mine's truck has ripped through two of them.

Takedown 03.21.2009 12:54 PM

Looks great CM! But you need lipo's man...

Candyman2 03.21.2009 02:35 PM

Ebay for the aluminium, im changing the shock oil now, and de-purpleing it, i'll see how it drives. initial tests were good, it felt nimble.

made a start on the shell

pb4ugo 03.21.2009 02:40 PM

Very nice truck! My question is about the spur though. I once mocked up a layout like yours with the center diff, and concluded I'd need a 42t spur to not have it protrude through the chassis on a CRT. Yours appears custom, did you have it made? What tooth count? Are you able to get acceptable ratios?

Candyman2 03.21.2009 02:44 PM

the spur is a standard kyosho 44t. I made the diff mounts so I was able to make it whatever height i wanted, I milled a small recess in the chassis but didnt go all the way through as i think it just lets dirt in, I just wanted the gear to sit as low as possible. Thne I put a plate under the rear gearbox to bring it inline with the centre unit.

coolhandcountry 03.21.2009 03:27 PM

Sweet build up.
I like the new RC.

pb4ugo 03.21.2009 04:33 PM

I'd never seen the Kyosho spur in white.

Looks like you did a good job with the 7deg front bend, how did you do that?

suicideneil 03.21.2009 05:11 PM

He's called the Candyman because all his builds are SWEET.

:mdr:

That is truelly beautiful though- the annoying thing is he can do shells and chassis', makes me green with envy....

Candyman2 03.21.2009 05:57 PM

thanks mate.

as for the bend it was a highly technical process of clamping the front bit in a vice and pushing on it like a mad man.

To be honest, the towers leave something to be desired (adjustment mostly) but the stock shocks are actually great shocks. Pretty much just need aluminum shock ends. They seem to be a problem.

As far as suspension and drivetrain, I know of a ton of things you can do to make it handle better than most newer truggies. I've done most of em to mine and it really helps. 8mm axles, buggy upper arms, 22* front hubs, Mugen tie rods, etc. Let me know if you want any more info on them.

Candyman2 03.22.2009 04:31 AM

im playing with shock oil at the mo, just to get it to a nice setup, might test again today. My rear axles are a bit shot, did I read right that hpi hellfire cvds fit?

masking takes so long on shells I find

drop shadow in, now silver ontop.

crazyjr 03.22.2009 04:57 AM

Beautiful truck CM, you could lose about 1/3 of the weight of the batteries with lipo's (more mah as well) but i won't push. I am glad the motor works good

i spy with my little eye.. your cad drawing on the background Ryan?

cad lol, a magic marker and some cardboard is my type of cad!

cut the pinstripe with a scalpel

and chromed it backed with black

If I'm not mistaken, the are a different length. I know some people have gone to the Hellfire suspension setup and that requires the Hellfire axles. Not sure on that though. Best bet is to get the LST CVD bones (~$25 for all 4 I think), LST CVD rebuild kit x2, and I believe Sportworks Mayhem stub axles. That leaves you with 8mm axles all around as well as CVDs all around instead of dog bones in the rear, and allows you to run 17mm hubs. Pretty much any buggy hub will work as long as the cross pin is 2.5mm I believe. CRT is 2.0mm if I remember correctly, so thats one of the few that isn't gonna be ideal (Learned that the hard way).

Candyman2 03.22.2009 12:08 PM

Right, thanks for the offer Bithead!

Ok then, I found some HB LSP cvds so i'll order them. I'll leave the rest of it alone, its all pretty beefy and its not like im racing or gonna be giving in a hard time, its got 17mm hubs already, so thats the main thing.

quite proud of this! I'll get some shots on the truck later, its still a bit wet at the moment.

Hard to tell, but you also used small chrome contrours too, right?

Those are nicely ground down dude- heavier fluid next time maybe? :mdr:
