It will be interesting to see if this reflex thread sticks around for any length of time. Most of them don't last long here. Lets hope this one has more luck.
Anyway....I have a Reflex too. I can't imagine having trouble finding parts unless your only looking on the wall of your local shop. Both TowerHobbies and SpeedtechR/C carry a full line of parts for the car. Currently I'm doing most of my parts ordering through my local shop. They can get in any Trinity or Kyosho
part I might want for the car.
What I'm running:
-Trinity Reflex
-O.S. .12TR
-Trinity in-line pipe set
-Trinity 1100mah reciever pack
-KO Propo 2173 steering servo
-Airtronics 94102 throttle servo
-Novak XXtra reciever
-Hitec Lynx 3D w/Spectra
-Mugen/FastTires 40shore all around 26mm fr/30mm Rr
-HPI Saleen S7 body
-Protoform Stratus 2.1 body
-OFNA starter box w/ power panel and gel cell
-Blue Thunder 20% Race Blend
Ummmmm......that about covers it!
