I like crawling and after the TLT and XR10 I'm trying to go on with a Wraith.
I'm conscious its performances cannot equal those of my Xr10 but I'm quite satisfied with it and I have room for improvements.
First of all: you cannot climb without additional weight on the front axle.
In this picture the weight is not forward biased and the climbing capabilities were seriously compromised.
Then I put my Xr10 wheels with the bullet weight and performances were far better.
I'm still trying to figure out which is the best width for crawling.
According to me the narrower the better, at least till 29 cm of width from outside to outside.
I made some tests using wheels with different offset for a total width of more than 30cm and here are the results:
it is too easy to find spots which are not large enough to let you go through.
At the moment the distance between the tires (interior to interior) is a bit less than 19 cm, so the axle is completely exposed for all this length. It is difficult on rough terrain to be able to touch majour obstacoles with the tire before than with the axle.
Again here is what can happen if the rock is not large enough: you are stuck with both tires in the air.
Although my feeling of being too large I noticed I have lots of interferences in the front.
I completely forget about them once I moved to a carbon fiber chassis for my Xr10, but now they are back.
In the pictures above you can see my front tires scrubbing against the body, but I checked and it scrubs against the tube chassis too. I think it is very hard to solve this problem because I don't want to change the chassis and I really doubt I can narrow it.
Perhaps I can change shocks setup increasing the distance between chassis and axle at full compression and using lots of droop in order to avoid an excessively high center of gravity.
By the way my twist is not very good, I would like to increase it of some degrees, I still have the stock shocks, do you suggest longer ones?
I like the way I put the drag link, I like much less the steering link and above all the servo horn.
I was forced by interference problems to use a plastic horn with a nut in the front. The drag link doesn't touch in the rocks anymore but those little nut is always against them.
Anyway I had lots of fun as you can see from the following photos.

After a few battery packs the WB8 WILD BOAR DRIVE SHAFTS are already winded. I suppose I have to move to something tougher but I don't know what to choose...
Waiting for your advices...
