Lord knows

M3 seems very pleased with his, and there's a lot of chat on the HPI forum about it.

I'd be interested to see how it's 3deg caster blocks at the front work on the slippery surface - the theory is that more caster is better when there's low grip.

I'd like to get my hands on the alloy spur gear mount it has as well.

Oh, and happy new year to you too - only about nine days to go until the next race meeting!

I saw one break in half just by hitting a drivers foot!!!

It was after a 5 minute heat. A guy crossed in front of the car to pickup his car, and the driver couldn't avoid it.

It was a small hit (the guy almost didn't notice). Everyone was really amazed how a crash like that could cause such damage.

I guess that this incident made a lot of racers think twice about buying a Pro 3 in the beggining of the championship.

yup the p3 i saw broke in that same way.....makes you think what that chasis is made of...to be so flexy and brake that easy...some kind of comosite plastic.....im thinking of geting a new chasis later in the year maybe the hpi graphite or the cross/penguin /kai or something like that.....its the way to go with these cars.....

that really does look bad! i cant even see how that could happen unless there was a bad weakness somewhere in that area.

M3,

That I can't tell you. The only thing I know is that the driver was the National Champion in title (he won the tittle with a Pro 2) and it was one of the first races of the Championship.

I guess it's a structural weakness of the chassis. The hit forced the chassis to bend upwards and it couldn't handle it. There was no upper deck at the time so all the flex at to be taken by the chassis.

The guy drives really well, he's carefull and he does not crash. This was at the end of a heat (batteries drained and all) and he made a couple of laps more to feel the car. In one of them he hit a FOOT. The car didn't move and when we picked the car it was like this.

Then this thing happened. It was bad and he was really pis*** because he almost had no time to change the chassis in time for the next heat.

I'm sure that a car with an upper deck would never break like that.

But then again my Yok Worlds just shed a front shock tower mount just because a guy spinned in front of me and I hit him. There's no way to tell that these things are going to happen.

However, I guess that there were some serious shortcomings on the car design or materials that make it break like this.

wow, i guess hpi slipped up when designing this car with no upper deck and whatever material they used for the chassis. i bought the hpi graphite chassis the day after i finished building it. hope that chassis doesnt bust.

Just put an upper deck on the car.

Those breaks would never happen with one

i saw a XXX buggy snap in half once, it touched rear tyres with a car it was overtaking, and flipped before hitting (still in the air) a concrete wall head on. it also broke to front arms i think.

Spaz 456,

If you want to retain the outer hinge pin you can either dremel a flat spot ( prefered), or put a drop of glue on the ends of the wishbones where the pins are located.

Flat spotting the pins works best IMO.
