Thanks for your information brother.... But my target has set to 501X as mentioned above...
Well, bro mike, I saw Avante2 at $720 in KWS today and couldn't resist... . Hope I can build it before your next party.
After reading your report, may be this DF03 is just for trial only so I didn't buy the expensive $320 TRF shocks.
By the way, T4 was selling at $1,630. I will think about Kyosho's ZX-5 if I find the fun of playing buggies again!
