I was looking on eBay and saw this.

380.00 seems to be the best price.

I run a 7.5 tekin gen 2 (best motor in market IMHO) in mine no motor timing, mild esc timing with 78/21.

I have the second punch rate turned down switch over around 75% and mild turbo as well. Make sure your shock oils are spot on for the big jumps, I finally got the dreaded tranny chassis wear on my old chassis going outdoors .

Yes, as SKengines said, they have a store in Orange, Ca. I have purchased quite a few things from them and never had any issues.

No the only tekin esc I have ever owned is the RX8. The hobbywing v3 is what I got for my 17.5 4wd and mod 2wd buggys and thats what I use for tuning the punch rate.

Oh sorry man duh... Yeah I like the tekin gen 2 better than the orions. The orion vsts are a pain to maintain. I like to check the bearings as much as possible and the front bearing is PITA on the orions. Also a bit down on power compared to the tekin gen2 although a bit smoother I have to say! My orion 6.5 and 8.5 are sale for that reason haah
