No, the chassis is still intact, I just bolted a longer 'cradle' to the bottom. I'll get some more pics later. I do have to trim the front and rear of the chassis, but not as much as I thought. The tyres rub on the 4 bottom link too, so have to get the wheel spacers on there as sonn as they arrive.

Yeh, stock gearing on the Wraith. I'm not keeping those tyres on though, I just did it to see how it would go. I know it's comparing apples and oranges, but I came to realise how grippy those Wraith tyres are. I do have wheel spacers on it, but they are only 13mm each side and yes they did rub. 20mm or so spacers would have done it I think.

So 550 motors have more torque than the 540's (mine are Johnson)...... do they run ok on 7.2 volt or do they need higher voltage? (talking Clod here again).

If you want to run the 21t "monster" 550's, you really need to plan on running twin packs of at least 14.4v total.

Thanks for that Andy.

Well I finally got to take it for a run! My aim at the beginning was to make it as fun as my Wraith. I've exceeded these expectations - the Clod is a blast to drive - a lot more fun than the Wraith!

I'm happy with all of the mods that I have done. I ended up doing all of the stage 1 and stage 2 mods in my first post (except 8.4v batteries). With the rear diff locked it climbs better than the Wraith and I think is just as fast. I'm going to talk the Mrs into racing with me tomorrow to find out for sure. It turns really tight too which I was a little suprised with. I thought locking the rear diff would hinder the steering, but I'm really happy with it. Run time seems similar to the Wraith. The EMaxx shocks (with red springs) are a little stiffer than I thought they would be, but still about right I reckon.

I bent the front steering link already when I hit a rock. I'll have to do some research on coming up with some kind of protection - or just watch where I am driving!

Sweet rig man, the extended cradle idea is really simple and works great. If you look at my ElectricBeast you can see a small easy front bumper idea too.

Nice work on the chassis lengthening the wheel base. It looks like a solid preformer!

Thanks guys. I'm really happy with the Clod. My Wraith nows seems like a flimsy toy now. The original idea was to let my son use the Clod while I used the Wraith. It's the other way around!

As far as bumpers go Brett tells me that the RC4wd skid plate will fit with the vertical servo mount and his steering links. I might get a couple of those......

That is a nice mod. If u need to widen wheels get esp wide ride kit. They work great plus does not put added pressure on axles like some spacers do. The 21t titans may have hidden crawling ablity.i can do minor crawling with my e maxx. The clod has a 34 to 1 ratio so that would work pretty good.

The wideners turned up this week, but I'm not going to use them as the clod goes fine as is. It isn't tippy at all. I think they might get used on the Wraith project I'm going to do.

ALL wideners put more pressure on the axle and axle tube assembly. Some probably are better than others, but if you think about it, moving those big+heavy wheels+tires further out gives them more leverage on the whole hub assembly, increasing wear and the potential for breakage.

However, in most cases it is nessesary to make the truck work better as a whole, so it's a price we just have to pay.

Oh...and the the clod has a 30:1 ratio unless you've changed your gearing.
(e-maxx is 20:1) :wink:

i have 12 tooth pinion so that is 33.87 ratio or ronded off to 34 to 1.
when i install the metal gear case i want, it will have adjustable mounts to where i can adjust from 24 to 1 all the way to 100 to 1
a large range

100/1? What pinion would you use to get that ratio?

other pinions would be:

9T 43.46:1
10T 39.11:1
11T 35.56:1
12T 32.59:1
13T 30.08:1 (stock)
14T 27.94:1
15T 26.07:1
16T 24.44:1
You would need a reduction unit to get 100:1 gearing.
Stormer reductions were the most popular back in the day....they are no longer made....and are pricey when you find one.
I think there are some alternate sized counter gears made, but not sure if they are overdrives or underdrives.

Hot Racing do a 100:1 gear set: http://www.ebay.com.au/itm/Hot-Racing-T ... 43ba93301d

Cheap too. Not that I looking to lower my gearing.

hot racing has this gear set for hi torque, it is on ebay for 48 bucks per set. to acheive 100 to 1 it requires this set and a 6t pinion, but i was surprised that i read it works with stock gear box. it would be neat to have that option. 100to 1 with dual 55t motors would be slow as a worm crawling.
i may buy 2 sets of gears, the set to acheive 100 to 1 with pinion and the regular set.
so much stuff to buy with for clods.
also i was looking at a eagle clod chassies. that looks to be a good crawler set up

A bit of an update, although nothing much to report.

I loved the locked rear so much I locked the front as well. I am using Hot Racing lockers off Ebay. The front steering is certainly reduced, but it still turns well (better than stock). I did some hill climbs today and it is a lot better. Very happy with this mod.

I also swapped out the red springs on the shocks for the stock clod springs, just to make the suspension a little softer.

I bought a Grave Digger body to use on my Wraith project, but it didn't quite fit. My 3yo daughter had a major roll today and the stocky body cracked in a major way ( I know, I know I shouldn't let my kids drive an RC until they are 16 - I'm a bad parent :wink: ). I sat the GD body on the clod and it looks kind of cool. It might make it's way on there.

The bug has bitten hard...... I decided to convert my Wraith into a MT. I now have Rumble tyres and the wheel wideners. Then I ordered a Ground Pounder too! Already ordered a couple of diff locks off Brett......
