er.. move to rc gen or offroad pls and sry
I purchased an HPI MT2 off ebay, so I sold my rustler and tc3, and am going to be selling my beat up Hyper7, along w/ all the nitro stuff that came with the MT2. I bought FIVE 2s 3100mah lipo packs, two 109d lipo chargers, and a powersupply for $350.. planning on running a Feigao540C-9L, with the packs in a 4s2p 6200mah pack, and sell the extra 2s pack.. 14.8volts should be good. I got my trusty ruler out the other night, and started getting measurements.. and last night I started CADing a new chassis for it..

originally, I wanted to lay the packs down along the sides, just like I designed my rustler's chassis.. this doesn't work with a spur gear in the middle..

standing them up seemed to work..

skip ahead, I made 2 heatsink/chassis reinforcement pieces.. the center spool you see is modled after an ofna PirateMT spool.. the spur size is alot bigger than what I'll actually be running..

threw in a Hacker C50XL and a 15t M1 pinion, just so I could get a better idea of how it'd look..

top deck, 1/16" aluminum.. I forgot to say the bottom will be 1/4" 6016 aluminum with extensive milling to reduce weight. (my rustler chassis out of 1/4" 7075 was WAY to heavy)

made top deck transparent so you (ME) can see what's going on..

side view:

front view, you can see there's not much room between the spur and the lipo's.. the spur i'm going to be using will be smaller though..

top view, you can see the holes in the top and bottom deck around the spur.. the front bearing holder, and rear bearing holder / motor mount will be keyed to the top and bottom chassis for more strength.

front brace in place.

rear brace/ motor mount done..

quick render:

closeup of the motor mount.. top deck will be screwed into the two little "tabs" that stick out..

that's all for now, I'll try and continue to update, when i do something groundbreaking Rolleyes

Nick, that is impressive! Here is another project along those lines, but not so ambitious.

Very cool project. I like tha computer graphics. I have an HPI RS4 MT electric with the Novak 5800, and I think it is pretty fast. I can't wait to see more of your project.

yeah, i've seen that before.. there's also two nitro MT2's that were converted to brushless on the URC boards.. camel_rc's is what made me decide to do this..

the same day i saw that thread, I started placing bids for mt2's on ebay ^_^.

I've never bashed with anyone from these or showme boards, because my vehicles were always being worked on.. that's why I decided to sell all my cars, and focus on one primary vehicle.. it's been over a year since I've run an rc car, but I've been building ideas for projects all this time.. time to get something running and bash with you guys..

nice to see you on the boards DualBL. I'm glad your bringing your RC knowledge over here, it's very appreciated.

Keep up the awesome work!

You should come out to the Berwyn Bash Oct.29th even if you don't have a RC to bring. You'd still have a ton of fun I'm sure

I've been thinking about it.. but I got to find a ride... berwyn isn't really next door to me Sad

. is there an actual head count so far? 10, 20, 30 people?

did you see the 30 page thread....lol

Over 30 people easy

we'll see..

as for my design..
just kind of tinkering.. chances are, I'll have lighter braces instead of the heatsinks on the lipos.. (serum) Wink

I'm not sure if my buddy can cut chamfers on all the edges though... but if he can, I'll do it, cause it looks sick..

quick chassis render:

higher quality render.. perhaps ill anodize it?

animation w/ and w/ out topdeck, and inside heatsinks.. i was just tinkering :W:

eh?

*edit
8am, didn't sleep...
better, or worse?

i have to start trimming the weight before I add anything else =\

Very cool CAD renderings...

I 'd put up pictures of my new project... but the crayons keep breaking!! Big Grin

..

i wanted to try my own design on the top deck as well.. and got went a little overboard..

alot of the cutout angles are too small for a 1mm bit to cut out =\
oh well, was fun..

and here's a wireframe for fun as well..

I have a 5' x 12' 3 axis flatbed CNC machine at my disposal. Let me know when you're ready.

Hey DualBL, Nice stuff as always. Hows that computer case doing ? =P

damn i cant wait till ill be able to do that. im taking a cad class in school and we are doing 3 view drawings. lol little kiddie stuff compared to that :p:

I'm good friends w/ Andrew of ColdFusionRacing, he cuts everything for me.. like my rustler chassis I designed for 16 cells Smile

thanks for the offer, but I've been working w/ him for years.

hey chitown, didn't recognize the name =\ case is doing great, all the other parts of my computer on the other hand are not.. I got 400gb of stuff i need, and am buying some more drives tommorow to backup/reformat Smile

I was horrible with acad in school.. solidworks is alot easier to use, and just as powerful.

Just a FYI ...DualBL aka -nick is only like 19 years old or something.....very talented

thanks tex.

I'm upgrading my computer in about a week.. going up to a Athlon64 3200+ and 1gb of pc3200 ram from a AthlonXP 2400+, and 768mb of pc2100 ram. also giving my mom my 80gb hard drive and getting a 400gb drive.. so I'll have my new drive, plus two 160gb drives for 720GB :joy:

as for my project...
http://s93886278.onlinehome.us/sv/index....T2_Renders

switched the C50XL for a Feigao 540C L..
http://s93886278.onlinehome.us/sv/BLMT2_...7540cL.jpg

not completely done, but one more solidworks session and it should be ready to have the test parts cut, to make sure everything works how it should.. the main structure is done. just little detailing left, and one more small piece that will connect the rear diff. case to the rear brace...
also added a little more bracing on the top deck, as it holds the battery holders in place, so I can't allow for any weak points.

bump because it's sexy now

just gotta finish making a few holes here and there, then the test pieces will be cut out of lexan to make sure everything lines up properly.

two screws will go through the top deck, the rear brace, and into the diffcase's holes.. no modifications needed to the stock diff cases Smile

is anyone watching this project?

yep, me! Good work man.

yes, but are those 5 pictures photos or cg images?????

Nice work dude.

DAVEC-NITRO-RS4 Wrote:yes, but are those 5 pictures photos or cg images?????

hard to tell eh? those are the test pieces.. just cut to make sure my measurements are spot on.. I measured everything with an old rusty aluminum ruler =\
after this project is payed for, i'm going to have to invest in a digital caliper Smile

rusty aluminum? Rolleyes

my bad.. steel.. beat me over the head Sad

test pieces are done...
so, I made one small mistake on the rear diffcase dimensions, and as a result, I have to design a small plate to make the rear brace attach to the diff..
Also, I'm not sure if I had used the wrong size for the Sub-C cells, but only 7cells will fit sxs flat per side.. 18 will fit total, if you build two 9cell hump packs.

[btw, the lower chassis is 1/16", while the final piece will be out of 1/4"]
