Hi all,

A while back I purchased a 1/18 HPI Micro RS4 roller, I used ProPulse parts to get it back up and running at which point it was fun but not really fast enough for me, in talking to the previous owner he mentioned a 540 motor mount for it so we did some research but couldn't find any of them anywhere however whilst looking around I came across a site (http://www.aktionrc.com/) that contained one of the most amazing chassis setups I've ever seen, they manufactured them in limited runs between 2004 and 2006 and finally sold of the remaining stock off in 2007, all attempts made to contact them via the web site failed and I was kind of bummed but not to be disheartened I continued to use the internet to research the two guys responsible for the chassis kits eventually finding one of their personal web sites, I shot him an email got chatting with him and convinced him to dig through his part boxes to see what he could find, amazingly he came across a complete Ice Blue SSG Micro Hybrid Conversion Kit:

This one was released in May 2004 in a limited less than 40 run, he combined the kit with a few of the new kit parts and sold it to me :)

So this is what I got:

The kit even comes with this nice little warning about it all being copyrighted and you not being allowed to rip them off :)

As you can see mine is signed which is totally going to increase future value :) Also don't think you can just go on eBay and pick one of these up, they are incredible hard to come buy as less than 500 chassis kits total where ever made.

The motor mount is from the newer style kit hence it's not in the same blue CF but it has been modified to accept a wider range of motor styles.

Overall the kit is amazing, everything fits together perfectly, they could have thrown in a Carbon Fiber bumper just to finish if of but otherwise this is one of the sickest platforms I have ever seen (oh and GPM make a CF bumper so I ordered one of those :))

The one thing mine didn't have was the instruction manual and with all the supplied hardware:

It took a little trial and error to get it all assembled:

But eventually I was up and running with the stock motor mount:

Which incidentally I could have stuck with but that sucky little high torque ProPulse motor just wasn't cutting it:

What a crappy top speed :) Instead I wanted to run this bad boy:

For those interested that's a 1/10 scale 15DT Team Mtronicks Racing 540 motor ;)

You have to do a decent amount of sanding to get the motor mount to align right but here it is once completed:

and then installed:

http://i250.photobucket.com/albums/gg244/TheB1gDude/micrors4/ts/DSCF4042.jpg

As you can see it's a tight fit :)

At this point I still planned on using the ProPulse ESC and RX but as it turned out the ESC was damaged which I guess was a good thing because it probably wouldn't have supported that monster motor anyway :) So out comes the big boy in the form of a 1/10 Msonik 4 RV15 ESC funnily enough it pairs up perfectly with that motor (thanks reaper :)) once that was installed this started to look a little bit more like the supercar it's supposed to be:

http://i250.photobucket.com/albums/gg244/TheB1gDude/micrors4/ts/DSCF4061.jpg

At this point I still had a number of parts on order so I moved on to the body, you need something wide to fit the chassis and as I didn't want to spend anymore money on this I used what I had purchased from Dale which was a 150MM Vauxhall Calibra DTM Bodyshell as it turned out it wasn't quite wide enough :( but as I had done all the painting and sticker work I stuck with it:

With a fully charged pack on the dyno:

I also switched from foam to slick tires so I think this is probably the fastest it's going to go.

60 km/h equals 37.3 mph

It maybe faster than that but I struggle to keep it on the dyno so I won't make any claims I can't backup :)

Let me know if you have questions or want to see something specific hopefully you will like this as much as I do.

Questions and comments welcome.

Thanks! Yeap it's quick alright! Must be 40MPH+ when on a nice flat spot of fresh tarmac. The crappy little dyno I was testing it on get's annihilated by it....

I need a dyno like that for 1/10 scale. That would be cool.

No I haven't, I only have a 1/18 brushless system not a 1/10 so I haven't worried about swapping them around. The guys who designed this chassis kit released a later version that was built to hold a lipo pack, they are really rare though and I've never come across one however I've seen these converted to nitro and various other crazy setups....
