I'm still acquiring the last few parts for my Wraith sand toy/Foff build and can't seem to make up my mind on the transmission. I've read through dozens of Foff build threads, and all of the wraith stickies, but I'm still torn. My powertrain consists of a Hobbywing 120amp sensored esc, 3400kv (3656 sized) 4pole sensored motor, 14/54 pinion/spur, standard ratio HD front R&P, HD UD rear R&P, and 2.8 sand paws. I'm currently planning to run my existing 3s packs, but 4s isn't out of the question in the future. I have other dedicated crawlers and go-fast RC's, this one is being built with dunes/sand in mind
I'm sure I'll be playing with the spur/pinion gearing, but I want to beef up the trans before the maiden voyage. I'm kicking around a few options and would like to hear some opinions:
1) Hot Racing cases with either SSD or HR gear set (2.6:1)
2) SSD high ratio kit (1.8:1)
3) SSD 2 speed (1.8:1 and 4.9:1)
4) just throw some HD gears in the stock cases (2.6:1)
Option #1 seems to be pretty tried and true.
Would #2 be a better option given my intended use? Cost is about the same as #1 and it would give me a nice bump in wheel speed, greater than switching to 4s. Not many people seem to run this trans, but it came out after most of the builds I've been reading. This is the option I've been favoring.
I hadn't really been considering the 2 speed until recently, but it does have the same high gear as the high ratio kit, and an uber low gear (allowing me to turn it into somewhat of a "crawler" along with a quick tire change?) for not much more money than the other options. The 2 speed would allow me to gear on the tall side for open dune running without giving up anything on the low end... or is that a moot point with my sensored brushless? I'm not really a fan of adding more moving parts if #1 or #2 are BETTER options.
#4 is cheap, but I have my doubts about the plastic housing living very long so I think I should probably skip this option?
Thoughts?
