At this point I'm not sure. I used an RS4 back in 2000 which was a pain trying to keep running. I then raced mostly a TC3 in 2002 outdoor and 2003 indoor (about a year break between). Now I have a Losi JRX-S that is not finished being built nor does it have all the electronics yet. However my track runs nitro and electric outdoor on Sundays and electric indoor on Wednesday. Which is why I am also looking for a nitro.
$200 to get started with a nitro car including engine is not bad, but if parts are scarce then I would have spent $200 on basically a dead weight. I just need something that will allow me to race competitively on our track which is a parking lot that we setup a track on. About 4 people have Mugens and about 4 people have NTC3s. The rest of the drivers have many different cars including V-one S and Mongoose.
I might just wait till next season for Nitro and just work on the electric indoor which last all year around. That way I could purchase the new Mugen MTX-4 when it comes out. I should be able to save a couple grad by then to get a nice engine, a good starting kit, and any hopups that might come along. Then people can just stare at my car as I am trying to get the thing started every race.
