Wassup T Jr,
There's finally a pulse on this page! Thank goodness. Since I upgraded my sedan from a MTX-3 to a GPX4 two months ago, I have been checking out this post for ideas and how-to'. Until lately, I pretty much read and listen. But recently, things have been eerily silent!? I've enjoyed putting the GPX4 Pro kit together for it's almost identical to my MTX-3. Because of the lack of available parts due to its discontinuation, I wanted a car similar to my MTX-3. Price was not really the issue in deciding my choice to buy the GPX4 over the MTX-4, but rather wanting something other then what every other Joe already has. Seeing someone like Jeff Lin racing against the likes of Mugen, Kyosho, Serpent, Team Magic, Etc., and winning his share of big races with the only OFNA represented, I must say that I am impressed.
I'm always rooting for and supporting the underdog. I have a great feeling this car will be money for me this season. The quality of the parts are A1 and the set up on this car is almost exact to my old MTX-3. If you saw my last posting, the only thing I want to acquire are titanium pillow balls.
The manual does list it as an upgrade, but I haven't been able to find them listed at Nitrohouse, RC Mart, E-Bay, or any source that sells Hobao/OFNA parts. I don't have my manual handy at this moment, but on my next post, I will note the stock# that was listed in the manual.
Til then, Cheerio.
