Wow, this is really cool! Finally the Lunch Box gets the 4x4 muscle it deserves! Pretty pro-looking btw, good job.

very very cool. you have to make a video.
Tizer
Well done! Looks very good

Nice work! I nearly missed this thought it was a stock VLB lol! Don't think I've ever seen a 4x4 one before I like it!

This is a totally awesome 4x4. looks mean as hell and perfect wheel base. A+ on your work and imagination. Well done inventor! strait to my faves
slimmy
Now this is how the lunch box should have ben made. Spectacular!!!

That is very, very cool
How does it drive?

This is the Box Tamiya should have built. Nice engineering and build. Congrats!

Nice work!
Great mixture of parts like a true factory Tamiya.

This beast looks like it would stomp through some mud or snow.

Thanks for the excellent comments everyone
. To answer the questions, the car drives very nicely, the gear ratio is a little low, with a standard 540 on a 20T (32DP) pinion it's probably a similar speed to a hotshot on a 7.2. The car corners very well and is stable due to having the battery mounted relatively low in the chassis and the stiff F350 springs. (I.e. on flat ground it will not tip with full throttle turns.). From memory the car will not wheelie from a standing start, but will wheelie readily from rapid reverse to full throttle fwds. Also it has a tendency to understeer at full throttle due to the short wheelbase and lack of center diff. I am currently in the middle of making some mods to it, but once they are complete I will try get a movie done of it to show what it goes like. I'm adding F350 spring clamps to hold the leaf springs in place, originally each axle was attached only by 4 screws and O rings going through the leaf springs, but this gave a lot of sideways give on the suspension, which I think is partly causing the high speed understeer. The downside is that the clamps have lowered the axles in relation to the gearbox, increasing the angles on the centre driveshafts to the point that the front one binds on the drive cup. (The rear one is made from modified txt-1 UJs, the centre section scratched by me for being a telescopic slider made from steel. WHen I get it sorted I will update the photos, and perhaps do a thread in the forum with some photos of the insides of the gearbox as well. The next major project I am working on is an 8x8x4 off roader made with thundershot suspension arms and fitted with tlt-1 / F350 wheels and tyres.
Thanks again for the comments, great forum,

That is way too sweet. Nice way to live up to your name.

Nice work man this must be rock solid ? how londg did this take you to do ? so when will you be making a set up for tc members
brendogs
put a lot of work in to that model well done looks superb

On and off, took a few months to build. Took me two weeks just to make the telescopic slider drive shaft for the rear end. Helps a lot having a milling machine and a small lathe though

Extremely nice job there! Now please run it and make a great video for us to watch
Henk4Focus
I have a better idea than video, box it and send it to my address. Plover crescent.........LOL! That is what a Lunchie should be. Mean and 4x4! Awesome stuff.
Hondabiker
Excellent! It looks like there's an awlot of engineering work gone into it, i love conversions!
kstar
Does it wheelie?
