I tried to wait for the pro 4 to be released, but I kinda lost interest over the last couple months, and decided to buy an R40.

Does anyone know the U.S. release date?

hi all,
i just tried out my pro4 yesterday, only managed a pack before the weather puts a stop to any further testing.
the car is setup as per manual, very smooth and easy to drive, but a tad lazy in the corners though. the drivetrain is very quietand smooth, that my fren thinks its a belt car. next step is to try a bit harder spring sets on it. i'll be using my xray evo2 springs, as they fit the spring holders nicely and almost the same length as the kit springs, only about 1mm longer.
i noticed that i have to tone down the steering dual rate a bit so as not to let the front wheels touch the lower shock mounting point, and loose out on some slow cornering radius. so any good ideas from all you pro4 owners to solve this? thanks...

Default Pro 4 at Snowbirds

I'll be trying my Pro 4 at the Snowbirds over the next week. I'll post how the car performs as soon as it gets some track time. Also the car did great for it's first outing on the pavement, TQ with the kit setup (less the swaybars).

Try 1 degree toe out or 0 degrees. It will prevent the wheels from touching the lower mounting positions AND improve the handling and response of the stock setup greatly.

Default Pro4 gearing

Out of interest, to anyone thats got the Pro 4, could they tell me what spur gear size is included (how many teeth) in the kit and what is the pinion, if there was one? Also the weight of the shock oil that was included, as this will help me the little bits and pieces i need.
Thanx

Still waiting in the UK for the Pro 4 !!!

Default SQUARE OPTION PARTS

Looks like Square has put more option parts..
shock towers, front graphite bumper support and the part everyone will sure to get the purple alum. transponder/servo mount...

http://www.rc-square.com/parts22.htm



I just received the Ti input shafts...very light!

front weighs in at 1.65g vs. 3.1g stock
Rear is 3.04g vs 5.6g.

the HPI graphite drive shaft is very light as well..

And Finally... my Beveled gears have arrived as well...
I can finally run the car...
no more overcooked gears...

What are the odds of that CF bumper support fitting a cuda? I'd really like one and they don't make them for the R2.

odds...0/1000000000000
I have the Cuda bumper support...the body holes don't match up.

Just a couple of quick questions to all the learned Pro4 drivers out there.
1. Do all 64P Pinion gears fit on the Pro4 or do you have to purchase a particular brand.
2. What type of Pinion spur combination are people using out there?

Cheers!
