Croc is rolling

frogger · #1 12-01-2008

The rolling chassis is ... rolling!

Very easy build, typical of Tamiya.

The Aeration shocks - very high quality BUT... the standard o-rings completely bind the shock shaft so they have to be rebuilt using the low friction o-rings from Tamiya (part #40530). Once the low friction o-rings are in (with a bit of shock slime) you have to cut quite a lot of coils from the springs. Buttery smooth! I have also removed some of the internal limiters on the front shocks to give more droop. They are super easy to bleed and build bubble free! But if I was buying again I would not waste my money on these and simply get some 3Racing Mini-t shocks.

Also - the Hitec HS-85MG servo fits straight in by cutting about 1mm of the tabs each side and it's also a direct fit to the included servo horn.

My 4100kv motor has not arrived yet so for the moment it has a Tekin 6.9 in as a place holder.

Well the original Tamiya of this style was10th. These beauts are Micro! 1/16th scale so quite alot smaller than the 10th

The GB-01 has been out for a little while now but alot of people have been seeing Jimmys at some of the Micro nationals and been going 'Woow!'. So with a bit of discussion on the UK-MicroRC forum we now have our own 2WD Open class at the next UK-Micro X (March), which is a 1 off event us Microers have every now and then, with the first Micro AGM being called a few weeks after the Micro-X and if everything goes well at this event hopefully we will keep our new 2WD class for next micro winter series

So quite a few people have bought the Tamiya GB-01, Mini-t's etc to support the new 2WD class

As Dan says it's a 1/16th scale new release of the old Desert Gator

You can fit any Tamtech off road body on it such as Frog, Hornet, DG, etc.

Electrics are in and very basic spray can paint job done to start with.

Running it with an 11.1v lipo battery and 6800kv Tekin brushless motor

I raced the car tonight for the first time at Wycombe and all I can say is WOW - it really drives just like a 1/10th scale 2WD buggy! Absolutely amazing.

In my opinion it has incredibly good steering (maybe all the alloy bits has something to do with it), jumps really well and is extremely, EXTREMELY robust (broken nothing all night despite 11.1v power and 6800kv brushless!!). Must get soft compound rear tyres though - the standard compound is OK once grip levels come up but the soft will be better!

There was a Mini-T there as well but unfortunately the guy had servo issues (no saver meant he kept breaking the gears) and so we didn't do a full race together. The Mini-T looked a bit smaller though.

Overall everyone that saw the Tamiya run commented on how well it seemed to go and was very impressed with lots of 'I can't believe how good it is and it's a Tamiya!' comments.

I was unsure about the 11.1v and 6800kv combo but it seemed very well suited to the car. I didn't once feel it was over powered. I'm going to fit the 4100kv for comparison anyway and will report back. I think the higher voltage theory has really proved itself tonight as the motor got barely warm and I felt I had good controllable power low down with none of the usuall stuttering at very low speed. Probably partly due to the fact that you can't hammer the 2WD as hard as a 4WD but still, very well suited.

As for all the alloy bits - I actually think this is one car that does really well with all the alloy bits as it adds a bit of weight which is no bad thing! Ready to race with all the alloy bits and the whole lot - 653gr - heavier than a RC18 and lighter than my Blaze. But, do you really need them - no, I don't think so - I recon all you really 'need' is the 3Racing steering assembly, maybe the front knuckles and c-hubs and then lastly nice oil shocks (and I don't recommend the Tamiya Aeration shocks as they are weird seem to work ok but they don't feel too good on the bench bounce test).

I am sold on 2WD micro racing - it is so rewarding to drive. It's totally different to 4WD driving (no surprise there ) and you have to think about your driving and be really smooth especially mid corner - no over revving or braking or even taking your finger off the throttle! Lots and lots of fun
