Crawling again

Hello fellas:

Most of you haven't seen anything crawl-related since my "Lifted Lux" Escalade project, which never really took off. Unable to live without a crawler, I started refining by existing crawler. The huge, gawky Futaba S3003 was pitched for a smaller, Hitec Hs-55. Next, the trans was rebuilt with all new parts with locked front and rear differntial. The batteries were relocated, and the whole truck was overall cleaned up. The slammed rims were coated with silver for a neater look, and anything weak was either replaced or re-worked. I just tested it to see what had come of my truck, and I was delighted to see my forward action was up to par, as it had been lacking before. (Gears slipped constantly) However, my reverse was seemingly non-existent. I have located my problem to be where I drilled the POT shaft too much, allowing the final gear to wobble or not swing in a circle, causing problems with gear mesh. I am not to upset with weak reverse, but I would prefer having it, as it is useful on the trail. If you can help me any on this matter, it would be greatly appreciated. I have ordered a 1984 GMC Pickup truck, and some Aoshima Super Swamper tires with Pentacle wheels. I am using these with my truck to create one similar to Xmodification's. However, it will be much different, in the paint-scheme. I plan on a color from Dupli-Color, so I have an authentic vehicle. Here are some chasiss pictures for you to enjoy and discuss.

Thank you,
Tyler Walker
