OFNA NEXX 8T TRUGGY ... Project Bumble Bee

[Sixtysixdeuce]

Looks like a heck of a score! Must've been some decent wheels you had.

the sad part is i dont even like nitro .. i just cant leave anything stock

Big block nitro in a tough 1/8 buggy or truggy is a whole different animal. I have an OFNA Ultra LX Comp with an LRP ZR.32 Spec 2, it is one quick buggy. And that's not even the hottest motor out there, just a darned good off road engine for $200.

The OFNA Force .32 you have is a solid performer. It's no LRP/OS/RB/Picco/Nova, but reliable, durable and easy to tune. I have the same engine in an RC10GT:





In this truck, it is WAY too much power. Totally uncontrollable at more 1/4 throttle. Fun, though But in that OFNA truggy, you'll be very pleased with the strong, smooth power. Not a high RPM screamer, but a great off-road engine.

If you do decide to convert to brushless, let me know what you'd want for the engine; I need a good replacement for the weak TLR .26SS in my Mega Baja.

thanks for the share

if i go electric ill let you know... right now i am just getting throu the rebuild and trying to find a decent servo as the old one didnt have enough power to turn the wheels at a stand still .. and it dosent have any gears left

i still cant find alot of info for set up ie shock oil, diff fluid, etc .. and waiting on parts

I run Savox SC-0252MG servos in my Ultra Comp. Pretty good bang for the buck at $37.

Guess it depends on what you want to do with it, but I like 30-40wt shock oil and 20k in the diffs.

[integra22t]

thanks it gives me a starting point

The common diff rates are 7k-10k front, 5k center, 3k-5k rear. shocks are typically 30-40

well i just got the cassy back from linex .. if anyone is intrested its going to be around 40-45 to have a chassy done .. sand blast, primer, linexed

im going to re drill the holes as the linex fills them .. on with the picts












i think this projrct is going to be called project Bumble Bee

As long as you don't put a yellow and black new camero body on it!

Oops...you probably should've installed screws in those holes prior to the Linex treatment! That's what you have to do for powdercoating and even chrome plating, or you end up having to re-tap everything.

What's the skinny on Linex? Never heard of it before...what are the pros & cons of that finish?

What's the skinny on Linex?

Tough stuff. AR500armor uses it as an anti-spawl coating on their level III ballistic plates. Bullets tear it up, but I expect it'll last a long time on an RC car.

this is a company near us that do spray in box liners for trucks .. they happend to be doing a safety trailer in yellow so they where able to do this instead of the normal black http://www.linex.com/

i wasnt worred about the screw holes as i just ran a drill throu them and used a bigger bit for the counter sink

hmmmm .... never

[integra22t]

well i ran into a problem .. when i was assembling the center diff ive found the outdrive cups very wore to the point that makes the shafts bind

tha part number i need is ofna 40005 but cant find it anywhere on ebay so i was hopeing that someone might know of a part i can use in its place

thanks

just found them on https://www.ofnawarehouse.com/index.php $24 shipped

[integra22t]

got some of it back together but waiting on arms and outdrives .. oh and servo







polished the radio plate, shock towers, suspension mounts, front brace, center link, motor fins, front, center, and rear brace

replaced 2 blown bearings, rebuilt all diffs, and shocks

[vwjuice]

That's lookiing pretty sweet. Funny how this started out as a "I'm not really into nitro" build.

[integra22t]

oh its just me .. dosent mater if its a hotwheels car, ebike or car ... ill mod it .. its my ocd

I was checking out your line-x treatment to your chassis. Interesting. I checked out the website and have a question for you. How did you get the top finish so smooth?

Thanks
