Thoughts on batteries, I am running a Tekin Rx8 with 1900kv. I am thinking I do not need a high C rating and the 4500-5000mah is the sweet spot for weight and capacity.

anyone running a t8i 1950?

is the wheel ok ? if not, put a screwdriver through the universal joint to keep it from turning. you should be able the screw the nut out.
If the thread in the aluminium is dead, you might have to use some force !
maybe with strong pliers you can force it to follow the steel thead of the shaft.
if this doesn't work, you might have to cut it carefully out !

I set up my buggy with Adam Drakes standard set up. Changed everything to match the sheet exactly. The gearing for that setup is 44/16. I ran this at the track today and when I temped my Tekin 1900 it was 209 degrees, ESC was 135. Anyone else running this gearing?
I did the exact same you did with my MBX7R-ECO, under the assumption it would make my current setup better and run cooler. NOT SO GOOD. switched to 44T/16 and my motor came off blazing hot, and per Randy Pike 220F+ was too hot. My advice is to take those setups they post with a grain of salt because they may or may not work. For Adam, maybe the 44T/16 is great, but for me the 44T/15 keeps my temps under control. I can run for 10 minutes with the 44T/15 combo and maybe get as hot as 186F. If I run the 44T/16, 5 minutes will put me upwards of 200F. If I start going down on the pinion too much it will heat up also, so the key is finding the sweet spot and staying there. It seems to me there is no such thing as BETTER with the gearing, its the sweet spot or worse..

I ran one in mine geared 17/46. It runs warmer than I'd like (230° after a 10 min main), but the power and speed is perfect. So much tamer than running a standard sized motor, I feel that I can pick up the throttle sooner and harder than a lot of other guys. Ideally I'd like to get the temp down 15-20°, but I'm not noticing any fade in power at all. If the motor makes it through the season at those temps, I'll be happy. The only place I feel any disadvantage from a power standpoint is the start of the race from a standstill. That same motor ran similar temps in my DEX8, which is what its going back into as I like the feel of that car better than the Mugen.

hey guys, I'm almost done building my kit. I built it by the book setup which is typically what I do to get a base feeling of what the "normal" car feels like then adjust from there. My question though is what are some "must haves" as far as upgrades (springs/pistons/etc)? I know Drake has a few setups put there, is that what is becoming a pretty good go-to? I race on larger, medium grip, outdoor tracks. I also saw his one setup had 10k/10k/6k I believe in the diffs. How is that working for those that have tried it?
