MissT

My Lunchie has a set of spiky GF01 tyres fitted to the rear wheels now. They have improved the grip by at least a third and when I say that even wet grass is no longer much of an obstacle then experienced Lunchie owners will surely understand! They don't balloon much, even with a 15T motor

The usual Tamiya mix of stylish and irrelevant lunacy

Good luck putting everything right. My kids and I get on well with the wheel type controllers. We bought a used car some time ago with a stick controller but just couldn't get used to it.

I had a 12T unbranded from Ebay and it failed after just a few runs. I must be unlucky with motors!

Yes, that was with glued tyres. The tyres are quite old and I'm sure the originals from the 90's. I ragged it on the beach today and it was begging for traction so I've finally given in and just ordered a pair of GF01 dump truck spike tyres for it. What 15T motor did you use? I had a Firebolt but it didn't last long and others have criticised them.

I've used an 1800 nimh and 3300 nimh and the only difference is run times. My sports tune motor was so disappointing in 3 different cars that I must assume it's faulty if yours is faster than a torque tuned ? I had a 15T motor in it for a short while but wrecked it in a different car so I reverted the Lunchie to a torque tuned. It was good and fast but the tyres couldn't cope on frosty grass! I'm going to experiment further with a new 15T motor and spiked rear tyres. I'm sure your esc is fine, I've used 2 or 3 different types amd I'm sure they made no difference to the speed.

It only really struggles on soft sand or in long grass and I think that could be down to the tyres.

The esc didn't mank any difference to any of my cars speed so far. Which esc is it? Are you using Tamiya motors? It may be the battery unable to power the motor properly, but I'm far from knowledgeable on electrics. Have you fitted ballrace bearings to your car, and have you lubricated the gearbox?

If they still work ok then why not? Lunchboxes and Bumpkins are all about having fun and they're so easy to fix, improve and buy parts for. And who doesn't smile when they see one wheelying out of control into a bush? ?

Good choices! There are a few other mods worth doing and if you haven't already discovered them just ask away ☺ I use 3300 nimh batteries and get about 15 minutes running those. I normally go through a couple of them and the motor has never got too hot.

I fitted Absima shocks to my Lunchbox. They've been completely reliable and needed nothing doing at all. About £25-30 for the four and they have been the best mod by far. Get a Torque Tuned motor instead of the sport tuned motor, it's faster but not difficult to control. The 5th shock isn't really essential but it is cheap and easy to do as well as being effective. A high torque steering servo is important because the extra power lifts the front wheels even more than usual. Good luck ☺

I've seen this method on a different site, or possibly Youtube but thanks anyway!

I have, through Ebay. My parts arrived quickly and with no problems.

I'm not taking the Pajero skydiving!

Thank you! I If I have an idea I'll let you know. I had a go at the rear suspension brackets the other day and sort of hit a dead end before achieving my aim, so I left it to await inspiration.
