Mudblaster project.

[TAZ-NZ]

This is a bit of a look at me post, but I figured I'd share what I was doing.

Here are some picture of my project Mudblaster. (original Mudblaster body on a modded Monster Beetle chassis.

So far it's got:

- Lower profile tires.

- oldfrogshot's custom rear axles, with oldfrogshot's modified TA03 drive cups & TA04 dog bones. (more info here http://www.tamiyaclub.com/xforum/topic.asp?TOPIC_ID=8104)

- CRP differential bearing supports

- All new stock transmission parts other than housing and side plates.

- Spur gear axle, mounting cups are super glued to transmission side housing to prevent them spinning.

- Complete bearing set.

- Parma rear sway bar.

- CRP adjustable motor mount

- 15t aluminum Pinon

- Parma aluminum side nerf bars.

- JG Heavy duty bumper.

- Half stock, half JG heavy duty steering arms.

- Custom lowered body mounts.

- Kyosho Magnetic Mayhem 22x1 Motor

- Hitec Hitec Aggressor CRX 3-Channel controller

- Hitec DXC Dual Conversion Receiver

- Hitec HS-325HB heavy duty ball bear servo

Things come or no yet fitted.

- CRP heavy duty steering blocks (stock ones are cracking.)

- CRP Bushed front arm set.

- Motor Heatsink.

- Aluminum rear hubs.

- Full length front skid plate.

- Parma Lexan body.

- Shock clamps.

- Servo cover.

Things I'd like:

servo horn stay.

JG front stock tower.

I tried a 10t pinon but it felt to slow, and it had so much rear wheel torque, it lifted the front wheels half a foot off the ground, every time it took off from a standing start.

I fitted the lower profile tires to reduce the ride height, and thus the center of gravity of the truck, to make it less likely to roll over.(it now will do a perfect on the spot 180 with out tipping.) They were also needed to clear the nerf bars.

I lower the body mounts as much as I could, to match the lower profile tires.

I plan to paint the lexan body metallic blue and apply an original decals set to it.

I've got a cooked trinity 3600mah NiMh matched cell battery, I need to replace it. (it got super hot charging, my mistake) I'm open to suggests on how save the battery if possible or what to replace it with and the name of a good battery charger, so it doesn't happen again.

In the process of getting the parts together I've also acquired 98% or a mint brat NIP, three sets of extra wheels plus some other misc wheels, a set of Airtonics 75hz radio gear i can use in New Zealand, and enough beat up parts to build 95 % of a black foot. plus a heap of other parts, and a few extra hop ups etc.

If anyone has any other ideas on anything I might add or do to this setup, let me know.

And what is it with frog family H-trees that makes people pay $100usd for them ??

Nice looking truck! I take it you didn't find many of those parts here in NZ?

No it's mostly ebay finds, the courier has been knocking on the door at 6:50am, twice a week for the best part of two months now.

I'm still waiting on a box of hop-ups and misc parts, as well as the lexan body.

Once I'm happy with the build, I'll have a sort out of what I've got and what I need, and a lot of stuff will be back up for auction. I not sure yet if i'll put them up locally on trademe or back on ebay.

Since I took the pics, I've fitted the CRP heavy duty steering blocks, something to do with a 40km impact with the roadside curb and ensuing three foot of air, that the already cracked stock items didn't like. [}]

The front stock mount tower is also now braced, with the fitting of a Super Blackfoot B10 servo cover, and modified Super Blackfoot B1 Manual speed controller mount. This gives more strength than the original servo cover with the cable ties at the back.

By the way, that's a nice collection you've got there in your showroom.

Hey Taz

It's looking coooooooooooooool[8D][8D][8D]so far. Good to see somebody doing something different.

I guess its going to be a runner but for those show'n'shine days you need to lose the front bumber for a custom alloy job.....not a criticism those front bumpers are effective protection but they look gross. Same can be said for most of Tamiya's models.

Carry on the good work and don't forget to post some updated pics when you're finished.

Most of mine are pretty standard setups. I have an M-chassis that has a few tricks and will have more added as I find them, but nothing like your beast! I have toyed with the idea of doing up a Blackfoot since it was my first Tamiya, but the fact that nothing is available locally has slowed me down. You might have supplied the inspiration to get me started!

How do you find the Mayhem goes in this truck? I have a spare Mayhem - might give it a go.

Chris,

I'm with you on the bumper's looks, but it's there for the very reason you stated "effective protection", I built this as a runner/basher, and as such it has to take any kind of punishment I can hand out. But I'm doing my best to make it look good too.

I'll post more pics once I get the last box of goodies I'm waiting for.

Bluefoot,

It goes well, and is about as fast as you would want to go and still try to corner. (but in saying that, the crusty 1700mah NiCd battery I'm using is probably holding it back.)

I wouldn't suggest running the Mayhem with the stock diff. ,it would probably eat the diff alive in minutes. I spent a lot of time on the transmission getting it to run as smoothly as possible, and the dog-bone setup really helps get the power to the ground.

I went with the Mayhem as I wanted something better than the stock motor and while my ESC can handle a 17t, anything that fast would have killed the weak Frog transmission in secs. So I figured a high torque 22t motor was a good place to start.

Once I get the steering sorted (there is a lot of play in all directions at the moment), I may see if I can get some more speed out of the setup, either with a gear change, or with a custom 10 cell battery. I'll probably only be happy once I've killed a couple of sets of transmission gears.

Gearboxes get mainy destroyed through high torque and not RPM, thats why also car or industrial gearboxes are primarily specified by the torque they can handle.
