TXT-1 Wheelbase

Hi guys, newbie question.

I'm starting to modify my TXT-1, using a couple of the builds on this forum for ideas. Basically I am doing the EVX-2, Emaxx 2 speed tranny, twin HPI 14.4V motors, low side mounted 6 cell packs, revo rod ends and revo shafts. Nothing too complicated as this is my first mod of an R/C beyond putting different wheels and tires on stuff. Couple of questions tho:

1. Is there an advantage to increasing the wheelbase? This is mainly a basher, not a racer, but I'm wondering if extending the wheelbase a bit will make it more stable on climbs? There is zero chance of me doing comp work so I don't care about rules.

2. If it IS an advantage, can I keep the standard cantilever joining rod thing, and just angle it back a little? I'm assuming the only other thing I have to do is lengthen the 4 link rods by an equal amount each.

3. Also, if I do lengthen it, how much should it be increased by?

Thanks for any info you can give,

Mat.

Mat,

1. Yes there is an advantage to extending the wheelbase on a crawler and a truck built for speed. Yes it is for stability. The wheelbase will make it more capable and stable during climbs and descends. As a crawler the extended wheelbase helps prevent cartwheeling on steep inclines.

1a. With a shaft driven truck though the extended wheelbase will also put more stress on the shaft.

2. Yes, you will only need to pick up (or make) some longer links. As for the cantilever push rod, the length can be kept stock but it depends on how much you extend the wheelbase.

3. Since this is not going to see competition then the length is totally up to you as long as the shafts are long enough (Revo's will give you plenty of room to play with). A good wheelbase for a capable crawler IMO should be 15-17".

Oh one more thing, the Emaxx tranny with its slipper will not be as potent as the stock tranny for crawling. Hope this helps some.

Sweet, thanks for the info Ceasar! I'll start doing that as soon as the revo shafts come in.

Another question - I have been running the hpi 14.4V motors, and 1 of them just burnt out! Stock pinions, stock gearbox, evx-2 esc. It accelerated up to top speed within only a couple of seconds, which was what I thought was the test for over gearing/undergearing... Do hpi motors do this a lot? ($35 each I might add - yay Australia) If so, what's either a) a good, tough motor or b) a cheap as 0000 motor that if I burn it out I won't care too much?

I can't get stuff from Tower Hobbies, cause they insist I email them a copy of my drivers license and my credit card. Wth is that about... Any other ideas?

Sweet! Thanks for that, I've emailed them, but if they are strict on the money order only from foreigners, then it's way cheaper to get local ones. International money order = $40 ish from my bank... :(

why not "bribe" an american to buy a stockpile of the motors and then you could pay-pal them the price of the motors/shipping/and a bit on top for their efforts

its a win win situation, you save the $40 of the money order, and they get a few bucks for their time
