Nice Rx3!!
I've always wanted a Rx3 in real life, but the only one I bumped into was for $6k!! It had a mild street port 12a with a 48mm Weber. It ran mid 14s on the quater mile. Not bad. The car was NOS bottle blue. Pretty clean, but not quite $6k material. I had a couple chances on a Rx2, but RX3 to me looks better. The R100 I test drove was severly rust cancered! I wa suprised that the little 10A(yes..10a) had some kick left in it. But I also passed on this. Kinda wish I didn't, but O well.
In the future..I hope to find one again that I can afford and hopefully have a 13b bridgeport installed.....Err! Err!Err!Err!Err!
Just to get back on topic alittle. Where did you find that RX3 model? Is it a Tamiya brand?
