Default Hpi Hlep

ok guys.. i dont know if there is any HPI guys in these forums but..
i race a sprint and im thinking about getting the CF chassis for it... OR a sprint 2.. ive researched the upgrades very carfully and essing i alreayd customed the steering and customed a Ti turnbuckle kit in the only reall difference is the chassis design and stiffness would the CF conversion for the sprint one bring it up to sprint 2 standard or should i get a sprint 2 (will there be a CF conversion for this??)

or are we about to see a new belt driven pro 5 some time soon

i'm not an hpi guy, but..

i don't think there will be carbon conversion for sprint2 as it is not just worth it...

pro5? maybe not for the next 2 year at least...

Exe, the HPI sprint is a very compedetive racer.. just because its aimed at beginners dont make it slow.. i have raced a evo3SL and Xray T1.. but found the sprint with adjustments only slightly slower than the xray. sorry if i have miss understood and u were saying the sprint 2 is a good car and can hold its own already

i know that sprint 2 is a very good car. i have some friends racing it... it has pretty much everything you need, and for a stater , it is a perfect car.

what i meant by saying it's not worth, that from the start it is a good car, but if you already start buying expensive stuff like carbon, better go for pro4, instead of tuning sprint2... if you just like buying option parts, believe me, you will have what to buy for pro4 my wish list is already for about 500$ worth option parts for pro4...

yeah . i agree teh pro 4 is arwsome but i really dislike shafties to much maintanance.. whole car needs to come apart to replace a single drivetrain bearing..
cant wait for another topline HPI belt drive.. might have to get a Mi2 or maybe the new xraywhen it comes out instead

actually everything is easier than it seems to be... unscrew the upper deck, take off turnbukles and you're in. i've done that for enough times and it is really easy. the most important thing is , that this car is almost indestructable

I love shaft driven, the pro 4 is awesome.
I would hate to see the Pro 5 be belt driven.
However, since you do need to wrench more with the Pro 4, I would like to see them design Aluminum Bulkheads like the Evo 4 and the Worlds Yokomo.
With all the wrenching, the graphite gets worn and you always run the risk of stripping the tap holes.
My vote is for a Shaft Pro 5 with alum bulkheads. However as mentioned before, thats a few years away.

Yes, Hpi and Square both make pretty much everything in alloy for the Pro 4.
Check All speed hobbies, they have a good selection of Square and Hpi alloy bits.

i own pro 4 and it has one of the most free, smoothest drivetrain out there right now. Buy it really is a pain in the ass to get to the diffs. But its worth it.

True dat!
I love the wrenching aspect of the hobby, so to me i love it.
However, I could understand how "drivers" would dislike that about the car.
But like axel said, its worth it! The car is dialed and smooth!
