Looks like a nice budget setup. Is that zippy pack from UnitedHobbies?

Sure is. Got it yesterday.

About as budget as you can get while not having to worry about stuff blowing up (hopefully).. :)

Got it most of the way finished up.

Photos probably would have looked cooler with some clean tires.. :).. anyway... Only things left would be a better strap (notice the cable-tie loop on the current battery strap) and some better wire management. Maybe some heat-resistant braid for the wires passing next to the motor to the rec. box or something.

It maybe cheap but is still looks really good. I'm going racing on the weekend and I am thinking that after I do I am going to want to build an electric buggy. You are going to have to tell us how that lipo goes.

That looks very similar to my setup before I switched to the novak, the primary difference being the motor was blue (9L) and the battery was black. :) The MM is hard too see but it's behind the motor.

The battery tray itself was made from white-finished aluminum. I then covered it with black adhesive vinyl. the white didn't look good :) The vinyl was scrap from a sign-making shop. I was charged only $3 for about 4 square feet worth which is plenty to easily cover 5-6 boxes... The padding inside is "Darice" brand "Foamies Sheets" sold at walmart for $0.47 per 9x12" sheet. It does not have an adhesive back but when matched with 3M Carpet Tape (very thin) it adheres quite well! The lower layer of foam is running lengthwise with holes cut for the button heads to sit in (as pictured above) while the top layer runs width wise and up the side walls to better cover the heads of the screws and protect the battery which is also pictured.

Here are the mounts we made for the box. Pretty simple. They raise the box just enough to clear the radius of the chassis edge and the side guard dirt deflector thing.

I ran it for a few minutes outside.. and decided to take some more shots. I kept my street-basher tires on. You can tell about half of the lugs are missing. Pretty crappy tires.. but I guess you can't complain for $20/set of 4 shipped premounted.

Tons of power! I can't imagine wanting more for any reason. Way more than you'd need for any normal track (unless you're doing a speed run or something). I hope to test runtimes tomorrow.

Towerpro MG996R servo. Amazing bang for the buck. Behaves like an $80 servo. Actual cost: under $12 at Hobby City

Mamba Max & CCBEC tray. Suspended from Motor Mount in front and supported by a standoff from the chassis in the rear. Note the purple standoff in photos above. Made from a baking pan. Holes drilled to secure capacitor, CCBEC & wires with cable ties.

Some body shots. All I have right now is the RTR body. Good enough, I suppose. Plenty of cooling, obvioulsy.

Lots of air flow to the heat sink here...

Air flow from here as well.

Silly dramatic wide shot. I thought I should have one of those.

nice pics :)
I really like Losi 8ight brushless conversions, both 8ight and 8ight-T.
I'm looking for a race roller 8ight-t sale to make it electric :).
many thanks for the pictures, you know we love them.

Yeah.. I had a brushless Hyper 7 for a while that I never really got to use much. It had an external receiver pack, 12x nimh batteries and was just kind of messy. At the same time as I finished my Hyper 7, Chapito started racing his electric 8ight-t at our local track. After a while I decided I wanted to take on a new challenge. Nitro. I had only ran it once before and didn't have good luck but figured I'm older now (I was probably 13 back then) and it would be fun to tackle. Well it's alright. Not great.. not terrible. I wasn't using the hyper barely at all, so I sold it and decided to convert the 8ight. In the meantime Chapito sold his 8ight-T and replaced it with an 8ight. So this week end will be the first BL 8ight battle at our track (as long as I can make it out there). Can't wait.

It would be great to get some video.. maybe I'll bring my video equipment along and get some video!
