Default hpi pro 4 can it hang with newer kits?

My friend is wanting to sell me a hpi pro 4 roller for $85, so is it worth it? Can it hang with newer kits, im just looking for a fun car that is easy to work on and can atleast hang with newer cars. i will be racing, but just for fun. i dont want a car that will just be getting smoked or break down every time i race.

I raced my Pro 4 for a couple years. With 19T brushed motors or equivalent, it's a great car. Anything more than that, and the shaft just vibrates like crazy. I'm pretty sure that's why most modern touring cars have belts. So if you plan to use a 13.5 brushless, you're good. Anything beyond that, it may not hold up.

What is better to race a shaft driven or belt driven car?

is not really out dated just discontinued most of the serious racers will be running belt drive which is known to handle a bit better but the shaft drive are know to be a little more durable drive train wise. on-road car seem to hold up well providing you don't crash it . just keep and eye on the rear diff if you going to put a brushless motor in it. i never had a vibrating drive shaft problem in the one i had but i just might had been lucky with mine

Well i had a trininty t spec and it was the biggest POS in the world no1 at my local track who had one (there was 4 others) ever finished a race without something messing up (usually drivetrain) and they were the hardest vehicles to work on; it was just a bad experience. so now im worry of what to buy now.

at the 85 dollar price range you could get a tc3 or tc4 that would hold up but not a big favorite at the tracks thats for sure. i guess the only way to be competitive it to get a tc5 or xray among others

The pro4 was not designed the best, mine had some problems with the diffs slipping and the center drive shaft binding in the cups under load. You definitely want something belt driven, look at the losi touring cars, they are built like tanks and still extremely competitive. It doesn't have to be new to be good.

There's also the Ofna car. Like I said, unless you plan to run hot mod motors to go 50+ mph, then a shaft is just fine. My 19T car went over 40 mph without issue. But once I put a brushless 5.5 in it, THAT'S when I started having problems. The shaft vibrated so much, it hit the battery and shot SPARKS! [&:] But that only happened at very high speeds. Everywhere else, it was a dream machine. I kicked much booty, and won several races with my Pro 4. Now I'm running it in VTA.

Here's the ofna I was describing. At about $120, it's a BARGAIN:

There's a thread on RC Tech; I might end up with one. I like the idea of minimal maintenance, and easy driving. It'd be a great VTA or GT car. I got an Xray T2R Pro so I could start under $300, and upgrade my way to T2 009.

thats a good like piece of kit. got all the good stuff you want for a cheap price by keeping it simple. fiber glass construction makes it light and cheap.

for 120 thats a great deal

how durable is the fiberglass construction? i havent had a vehicle that uses that. im planning on running it in rcgt class with a 17.5 brushless. just watched the youtube video of jeffery linn winning the championship with his bone stok jl10. thanks i found the forum on rctech lot of good info, and i havent read to many complaints about it.

get it the hpi pro 4 was sweet, it handled much like todays hot bodies cars (cyclone)..very smooth and they carried alot of corner speed when set up right..  and corner speed is key thats why the xray is so sikk.
