Finished my ET48.3 build and it went very well. I had a problem with my shock bladder getting sucked into the shock body. I tried building the shock a dozen different times and it still got sucked in. I replaced that bladder with the one out of my extra 410.3 shock and it worked fine, not sure why.

I also am using the 1700 KV Tekin truggy motor with a 16 tooth pinion. Seems kind of slow on 4S (some drivers recommend it). I will try it with a 17 tooth pinion and go from there. My standard ET48 had a Tekin 2050 kv buggy motor and it was pretty powerful.
