SWorkz S12-1R "US Edition" 1/10 2WD Mid Motor Electric Buggy Kit
I own the s12-1r usa edition witch I bought threw amain at my local hobby shop, thank you amain for having a dealer network now also. I just finished the build. very quality . the plastics that are used in the arms and various other parts is extremely tough and the ball cups are insanely strong. I believe they are even better then any of the rpm or kyosho cups. if you buy this kit expecting to only have the mid-center upright gear box and the rear motor gear box you will be wrong. this kit comes with that box yes but it also comes with the mid forward laydown gear box as well. now this is all good an well in fact the quality is top notch and I believe is above the big 3 kits from tlr ae any kyosho . the odd thing is the instruction manual. and the parts bags are not sworks normal. I own the ek1 and s104evo and the manuals and parts bags are labled and follow the manual really quiet well, this can not be said for the s12-mr. this kit is much like the AE kits where they bulk the bearings in one bag all one type of screw in another and another bag has a different type of screw. you need to open multiple bags to fetch parts for one step instead of just opening up one bag to do that step. I found it slightly confusing at first. then not a big issue but for set up tips you need to flip to the back of the book to check set up tips while building it as there are no notes on any one given step. also the shocks in this kit vers the 104evo may be the same shock with the pro seals the s12 shocks are very stiff in there stroke motion where the 104evo where looser. they are smooth and very nice but very very stiff. feel like 100 wt vers 20 wt oil when using 20 wt oil. also I found an inconsistency in the shims for the hinge pins ect but just spend the 6 bucks and buy the aluminum shim kits. other then that I do recommend this kit , its showing to be a very fast kit.

SWorkz S12-1R "US Edition" 1/10 2WD Mid Motor Electric Buggy Kit
This buggy is awesome!!! I haven't put 100% of my effort into dialing this buggy in and so far im on pace with the B5M. I have scored tq and a win on it already. I am however running on wet clay track with slicks and I have the s12-1m, so If I was running on dry dirt id go with the R version. The buggy is very durable and has amazing steering.
