FLM SPV2 Crawler Build - Designer StampedeProject
 

Born out of a a want and need for a more universal style chassis, I developed and designed the SPV1 and SPV2 chassis. Currently the designs are licensed to FLM (Fast Lane Machine) and now available from RC-Monster.com

It all started when I heard of Losi's mini-crawler several months back. I though a mini-scale crawler would be cool, but how about a true 1/12th scale... durable and easily built based via Wheelie King parts, a Traxxas Stampede tranny and whatever else I had laying around. The result was my below 1/12th scale FrankenCrawler with parts from just about everywhere. The FrankenCrawler was very capable considering it has a Stampede tranny, Wheelie King axles, mix and match driveshafts, EMaxx Shocks (later Axial Shocks) and of course the original prototype of the SPV1 chassis.

It suddenly occurred to me that if a plate style chassis was flexible enough it could be used on anything from a mini to super class builds and satisfy everyone from the Clod, Berg, Wheelie King, Axial, and other builds with about every hole you could need all in one chassis and still be USRCCA compliant. The result was the SPV1 & SPV2 - StampedeProject Version 21Chassis shown here with the original black Derlin prototype. The SPV1 was designed specially as a bolt up replacement chassis for the stock Axial chassis.

I worked up the first below test version on CAD and had Jamie at FLM cut the blank. I mentioned to Jamie that John Robert Holmes would provide un-hindered feedback and we ended up with the second version thanks to some excellent recommendations from Holmes. What we realized was that not everyone wanted all the prolific perforations in the chassis and extreme adjustment capabilities probably were not needed for most people, but we decided to offer two chassis side plate versions one Universal chassis with all the holes in the below chassis, and then a cleaner Standard version like the one Holmes ran at nationals and pictured a little further down. We also beefed up the lower windowsill and moved the front windshield forward for those people that are running a slipper clutch. The chassis plates will all bolt directly to a stock Axial chassis.

Another thing Holmes pointed out right away was how cool the chassis worked with on a Berg setup. We are going to offer the chassis in either Universal (above) or the less holy Standard version (shown below on Holmes chassis running Nationals in Moab with a Berg setup) with either Axial width chassis spacers or narrower spacers for Berg, Clod, Gmade or other Dual tranny builds.

Below represent the final two chassis plate designs with each offered in either 55mm or 81mm (Axial width) spacers. The SPV1 is the more holey (highly adjustable) plate design and the SPV2 is the version that still provides plenty of tuning flexibility, but cuts down on the holes in the chassis.

The Marketing Info I wrote to explain the different versions.

FLM's SPV1-81 & SPV2-81 Rock Crawler Chassis - For AX10 & Other Driveshaft Crawlers

This super light and durable 81mm spacer width chassis is specifically designed as a direct bodiless stock chassis replacement for the Axial Scorpion AX10 using the stock skid plate. The chassis also works great for anyone doing a custom HPI Wheelie King, or Tamiya TXT/TLT rock Crawler build. The milled 81mm chassis spacers are drilled, tapped and ready for your body panels or scale accessories to be mounted. Both the SPV1-81 and SPV2-81 chassis will accommodate Axial, Losi Crawler, EMaxx and other similar rock crawler shocks in both sprung and droop crawler suspension configurations. For those wanting the ultimate in mounting flexibility, the SPV1-81's extra tuning holes will provide the customer crawler builder nearly unlimited tuning options. This chassis conforms to the 2008 USRCCA chassis rules for competition with required hood, roof and door body panels (not included) installed. The SPV1 and SPV2 chassis are StampedeProject.com designs.

Approximate Weight 5oz.

SPV1-81 & SPV2-81 Chassis Include:
Chassis plates
Seven (7) - 81mm Milled Chassis Spacers
Fourteen (14) - 3mm Machine Screws
Four (4) - Milled Shock Mount Offsets



FLM's SPV1-55 & SPV2-55 Rock Crawler Chassis - For 2.2 Class Berg & Clod Crawlers

This super light and durable 55mm spacer width chassis is specifically designed as a direct bodiless chassis for Berg and Tamiya Clodbuster style rock crawler builds. The milled 55mm chassis spacers are drilled, tapped and ready for your body panels or scale accessories to be mounted. Both the SPV1-55 and SPV2-55 chassis will accommodate Axial, Losi Crawler, EMaxx and other similar rock crawler shocks in both sprung and droop crawler suspension configurations. For those wanting the ultimate in mounting flexibility, the SPV1-55's extra tuning holes will provide the customer crawler builder nearly unlimited tuning options. With the included 8mm body panels spacers installed and required hood, roof and door body panels (no included), this chassis conforms to the 2008 USRCCA chassis rules for competition. The SPV1 and SPV2 chassis are StampedeProject.com designs.

Approximate Weight 5oz.

SPV1-55 & SPV2-55 Chassis Include:
Chassis plates
Seven (7) - 55mm Milled Chassis Spacers
Fourteen (14) - 3mm Machine Screws
Four (4) - Milled Shock Mount Offsets
Four (4) - 8mm Milled Body Panel Offsets

------------------------

Want to run a droop suspension setup - either chassis has the holes for you.

THE RTR BUILD
Just to assure everything was lined up I picked up a Axial RTR and simply swapped out the stock chassis with the SPV2-81 (the less holey standard chassis with Axial width chassis spacers). I forsee a rock racer build in my future.

Since I figured I should have a final production SPV2-81 version showing up after all the initial orders are filled, I pulled off the test chassis and dropped on a the last SPv2-81 prototype and snapped a couple more picks. Then gave it a good thrashing. Enjoy the poser pics.

I omitted side body panel for this build. For comps you don't need all the extra top body panels, just a hood, roof, and side panels, but I though it would look cool.

The paint by the way, I did just by laying door screen down, misting with black then following with red then backed in white - not a bad carbon fiber fake. The body panels shown is just a 80mm width piece of scrape Lexan bent to match up with the body posts. The paint that makes it look like Carbon Fiber/Graphite was don just by hand painting "SPV2" in red paint, backing that in black with the airbrush. The rest of the body was really simple. Lay down some door screen spray with black paint, remove, spray with red paint, then pack with white.

One of the things I am really liking is all the adjustment on the chassis especially with the shocks.

Almost forgot -
This pictured chassis kit is available here http://www.rc-monster.com/proddetail.php?prod=flm71500

Tony - I saw this last night and I bought one today! I hope you get royalties!

This is a great looking chassis for those wanting a bolt-on semi-tube frame style chassis. For the price, these will be hard to beat. Definitely nicer looking than the TCS Edge.

Wow, only $60... If I didn't already have a fully functional custom body-less chassis for my crawler I would totally buy one. It looks great!

I just need to buy an axial or maybe a berg. Love the chassis and I want one.

Thanks guys. I licensed the design to FLM so let's hope the sell a million of them. :yes:

On the price, yeah I was stunned too :surprised: when Jamie at FLM said he was going to set the price at $60, especially when most chassis are in the $80+ range easily.

I doubt in the still small crawler market that could happen by one can always hope.

Cool - let's see your builds and hit me with any questions.

That's bichen..:great:. I hope you sell two million :party:

That looks unreal

Looks like RC-Monster has these in stock!!!

This chassis works great as a slow go crawler and as a high speed basher. Here is a Rock Racer build I did with a Tekin R1 and a Tekin Brushless 3700Kv and a Axial RTR. Fast and a blast to bash.

What batts are you using with the Tekin system?

5000Mh MaxAmps 7.2V Pack mounted on a Axial battery tray/servo mount at the rear - But I intend to drop in my 3S pack at some point.

I have most of the bit now or on order to complete my build - The only minor issue I had is that FLM missed the shock standoffs from my package so they are being sent.

Also I thought you mentioned templates for the lexan cutout was being included.

Might be nice in due course to include some instructions or sample link positions for Noobs like me... :)

Great idea - let me see what I can whip up.
