You need to put a heatsink on the esc and preferable a mini 5v cooling fan blowing at it, and tap the 5v thru the receiver. You can get those mini heatsinks meant for cooling motherboard chipset (not the CPU heatsink). If you cant find 5v fan, then get the smallest 12v fan and tap it directly from the battery. Alternatively you can cut a hole in the front of the body where airflow will hopefully pass over the esc heatsink. But cooling fan is far more effective.

some say that the 101bk is able to take up to 23T, but i feel that 27T fits best because it gets really hot running with 101bk and you won't feel safe in your head if you are going to run it through 5 sticks. still its best to get an unlimited ESC. with that, you can pump in a 19 pinion with your RZ.

then sit back and watch.............

i've ever tried 19 pinion with RZ and 101bk. 5min run is all i have and that esc gets damn HOT! shuts down! no good!

Ken4 · #**703** 02-09-2007, 03:43 AM

Even with low-turn ESC you will still need some sort of cooling if you plan to use low-turn motor and good battery pack (e.g. >4000mah). In some cases even the tamiya connector is not good enuf, I've had so many melt and fuse together. Deans plugs would be ideal.

Here is a video of my 8 year old son driving the gator with the new wing. The new wing rocks!

Hi guys,

I'm still on the hunt for a 19t pinion (got to beat thet Frog)........if you have time please take a look at this link to ebay and let me know if you think the pinions are suitable for my gator

http://cgi.ebay.co.uk/Tamiya-18T-19T...QQcmdZViewItem

Also, can I ask you wise guys if I will notice much more power, speed if I use a 3700mah battery instead of the 1900mah I use at the moment....or will it just improve run time??

Ps.....found a tip>>>>>>>>drop your aerial pipe into boiling water to soften in up and apparently stops them from snapping!! I got a real issue withn the Tamiya pipes so...hopefully this will work??

Hope your all well........Ken, your Gator is so fast it looks nitro powerd!!

Ken4 · #**706** 02-10-2007, 07:33 PM

That's the wrong pinion gear, wrong pitch, will not fit. The part no. you must get is 3515007 which is the correct 19T.

A normal 3700mah battery will not improve power, unless you get the high quality type where it has lower internal resistences and therefore higher voltages, e.g.

http://www.nosram.com/products.asp?id=32

but with higher voltages the esc will usually overheat and need more cooling.

all
Well after days of deliberation, (with myself) I've decided to step off in the effort to make my Gator a rocketship

. Apart from goin brushless, (and I aint forkin` out $500+++) I'm going to be putting either my Sport Tuned or GT Tuned back in, taking off the DF-02 aluminium shocks and putting the stock ones back in, replacing the ball-diff with the gear diff. All this $$$ I spent on it, and in my opinion, has made it worse.

Example #1 Ball-diff creates too noise. And it's made right, been fiddled with non-stop, and still sounds like crap.

Example #2 DF-02 shocks are great, lands perfectly after big jump. But land it upside-down and the front plastic shock caps wearout and the shocks pop off the mount. Okay I did change all the mounting points from as per manual, to ball connectors, which probaly didn't help (but they looked sweet) Now I'm not talking about little girlie jumps, as seen in my videos, I go for BIG air.

Example #3 Super Stock RZ, awesome power (helpful in the serch for BIG air) heats ups the ESC far too much for my liking. In fact, after running the RZ yesterday and the ESC falling out the side (okay it wasn't mounted properly) of the Gator and being dragged along the ground. It aint working anymore.

Apart from spending more money on it, which I can't see happening in the near future, (Besides, I've got 2 new toys arriving over the next couple of months.) I'm sending it back to partial stock form

. That was the main reason I bought it, it's a great buggy straight out of the box. With the sport tuned behind it, I'm sure it'll be just fine. Long run times is what I'd really like.

Sorry if this has depressed some of you, but as I don't race it and probaly never will, it'll do me just fine `round the garden, skate parks, and BMX tracks.

Cheers all
Later
Del

So what 2 new toys are coming your way?

toonz · #**709** 02-11-2007, 02:17 PM

hihi del

yes i can understand your point of view. the DT02 is already a fast car by nature. like what we talked about last time that this car doesn't require much to pump up and i still stand by the DT02.

the ball diff does makes noise and taking it apart (i hate the process) for maintainance is really troublesome whereas a diff gear can be left in there for a long long time.

as speaking of the df02 shocks. i'm not even using the df02 spring anymore, gone back to my dt02 hop-up springs. the diameter of the df02 spring is to thick and its always hitting my rear turnbuckle and scratches the bottom cap of the shocks. i think you can still continue to use the df02 shocks, just use a longer screw to secure it and they will stay.

the rz does heat up big time and after mine died, i went on to use the dirtuned and so far i'm happy with it. like you said, we don't race, we just want to run run run run run run.........

go DT02! one of the best stock cars around

Hiya Ken & others,
Got a TamTech Gear Gator coming in the next two weeks. Then sometime in March, got the new M04L Beetle coming. Gonna put the RZ in that, and hope to upgrade the ESC for it.
Love my VW Beetles.

Chose the TamTech Gator over all the others, just purely for the fact that I've got the 1/10th version.

Toonz. Yeah "ROCK ON THE DT02"

Good choice! I got a beetle too, but it's a baja beetle, it rocks!

Ken4,
Yeah mate gotta `ave a beetle on roader. Hoping to find a certain Tamiya chassis and build a drag/street machine. Thought about mounting a Bug body on the Gator, but some how I don't think it'll look right. it has been done before though.

toonz · #**713** 02-11-2007, 11:23 PM

del, what's your plan for the mini gator?

i feel like building a new DT02....

Ken4 · #**714** 02-12-2007, 01:12 AM

It's hard to find DT02 now, stargek out of stock. Only DF03 left or the $$$ 501x....

Toonz. Haven't really got anything big in mind, just a couple of Hop-ups. Shocks will be the first to be changed, then the motor. Can get a brushless system for it for around $150.00. Might look at that, but like I said earlier I aint gonna race it so it might be a waste of hard earned $$$$$$$$$$$$$ They do a Sport Tuned for them, that might be a cheaper option.

toonz · #**716** 02-12-2007, 01:58 AM

there is a new mini sport tuned too....

mini sport tuned

most of the hop-up for the tamtech are just bling.
having a good motor and oil shocks is good enough already....

the plastic cva will be available soon, much cheaper then the alu ones...

Ken4 · #**717** 02-13-2007, 04:53 AM

Hehe....my gator finally got its revenge on my mate's DI. I put new rear spike tires and it was doing huge jumps. Unfortunately the DI had a broken rear diff and could not go full throttle. So gator wins by default.

toonz · #**718** 02-13-2007, 05:14 AM

how did the DI break? hmmm i'm been hearing a lot about DI breaking here and there.....and i wonder why.....

nice vid ken. i notice the gator tends to get unstable upon landing.
here's a little constuctive tips to share with you...

as you're approaching the hump (of course entering straight), slow down or hold on to one third of the throttle, when you're entering the hump, increase speed, once you reach the tip of the hump, give full power.

if the front is diving down in mid-air, give a throttle to straighten it.
if the back is tilting down in mid-air, give a reverse brake to balance it.

the car will usually land on 4 wheels, then you power up again.

just a little tips, hope it helps

Ken4 · #**719** 02-13-2007, 06:12 AM

Thanks for the tips. I give it a try next time.

He put a brushless in his DI running ~49,000rpm. DI not designed for this kind of power, nor is it designed for doing big jumps. Something will break.

Maybe the 501x is more bash proof.

toonz · #**720** 02-13-2007, 10:53 AM

its always safe to make a height of one feet or go gentle with the jumps. infact, anything can and will happen as long as a car goes on a track.

the 501x may be strong but i wil say that its not bash proof. i've held one fully built in my hand when i look at all the parts, something will sure fly out if i drop it at meter. but then who will do that hahahaha........

toonz · #**721** 02-13-2007, 10:54 AM

got a DI from my girlfriend tonight....valentine's gift

Royal Male · #**722** 02-13-2007, 12:34 PM

Your a lucky man Toonz.....I hope this don't mean you will be jumping ship over to the DI forum???

I'm thinking of getting an m03 chassis mini cooper.......there's no way my girlfriend would buy it for me...I will actually have to get it posted to work so she don't find out.......so Toonz you are a very lucky man!!

toonz · #**723** 02-13-2007, 02:27 PM

thanks rm

i will continue to be in our dt02 thread, its my little home you know

but you can still find my post in the hornet/grasshopper, wild willy and now DI as well.....hehehe...so "busy"

the m03 is really a nice car to roll around with, go get it man! show your girlfriend, get her interested. we even have a m03 thread at the electric on road section, lots of tips there!

Ken4 · #**724** 02-14-2007, 03:37 AM

I was at stargek today (my LHS), very difficult to get spares now for my DT02. Driveshaft dogbones no stock. Wheel axle cups no stock.

Looks like it's time to retire my gator.

Metla · #**725** 02-14-2007, 04:23 AM

I cant see why they cant get them?, The kit is still being made, The spares are available from Tamiya.

Having said that, You shouldn't have been using dog-bones with a modified motor in the first place, I have heard of people using the after market universals available for the DF03 as a replacement for the dogbones, This may also replace what you have described as Wheel axle cups? (which, If they are what I think they are, are a standard Tamiya part used on dozens upon dozens of their models)
