Hey Neil how you doing? Front shaft is indeed going to be about a foot long, I was going to get one made up, then I had a "what the hell am i doing" moment, im the candyman! I can make one!

besides getting a dog bone made would require a cup each end, currently it has a cv joint at the gearbox end and I want to keep this.
Lipo-no no for me, no need, I can either get a set of 6s lipos and a charger and change the layout on my emaxx and this for them, or just use what I already have sitting here, 3 sets of 18 cell packs that are pretty good. Yes they are a bit heavier but they still propel my vehicles to silly speeds. Also with all you guys selling your nimh's off on ebay I can pick up a bargain! lol the last set of 18 matched cost me £45, thats $60 lol.
Now back to the action. This was a very hard bit to do, the alignment of the diff has to be spot on else it will bind, using a shaft allows for nearly almost angle, but being direct it has to mate perfectly. Getting it to stay in place whilst drilling the hols from underneath was hard but not impossible, now done ok. I also cut a slight recess in the chassis for the spur gear to sit in.
Top deck will be something like this, bit of a fancy long job but I wanted it to look cool, lus I really liked emaxlers chassis desing and wanted something similar and very symetrical
