Pretty much got down to a choice between the pro4 and the xray t1
fk

So far it is a pretty hard choice, and i am weighing up pros and cons
of each

HPI PRO4
Pros
aluminium hinge pin mounts
shaft drive - no chewed belts
carbon reinforced plastic belts
comes with hub carriers with different caster angles
aluminium shock bodies, threaded
comes with sway bars
antidive/squat etc easily adjusted with shims
very low CoG
4 ackerman settings
Ti turnbuckles
alloy driveshafts
driven by Hara


Cons
possible chewed bevel gears
very fragile front one way, aftermarket backing plate can help
strengthen though
fragile front suspension apparantly
possible torque steer from shaft drive layout
harder to balance with battery down one side
hard to get parts for
chassis plates requre sanding and filing
dearer than xray
hex hubs have washer/spacers on them

XRAY T1 FK
Pros
chassis does not require sanding (done at factory, just needs glueing)
belt drive has no torque steer
very free drivetrain
good bearings
dust seals for ball diff
flexibility in battery placement including saddle pack
externally adjustable shocks
build quality is apparantly excellent
apparantly parts are easier to get hold of
externally adjustable diffs
spring steel is apparantly very strong
lightweight parts
antidive/squat adjusted without shims but only two positions



Cons
plastic shock bodies
no swaybars included standard
still have issues with belts and rocks damaging them though as the
diffs are open it should be less a problem than with the TA04 which
has semi enclosed gearboxes, letting rocks in but they cant get out
hudy Spring Steel driveshafts and turnbuckles heavier than
aluminium/ti/plastic parts on pro4?
changing front caster requires purchase of more hub carriers
cheaper than pro4
do you have to pull the bulkhed off the car (including suspension and
shock mount and top plate) to get a diff out?


Will add anything else to the list i can think of when i think of it/find it


Notes
I dont think the one way front diff on either car would overly suit our
tracks, would have to try but would possibly fit a ball diff in the front
in the end

the xray is a better car in my opinion. there is a stack of info on both cars in the rctech forums. just watched both of them run last nite in mod both running 7doubles.


speak to owners of both cars if possible and do not over look the importance of parts supply if you race. nothing more annoying then missing out on a race on account of a10 buck part cos theres none in the country

Exactly
Xray importer tells me they have everything in stock.

Noone I know of in tassie has one of either car


but I would be a ground breaker


I also think the chassis layout and battery placement options on the
xray are huge bonus's

LOL yes well I PM'd him and posted on the for sale page that I was
interested and I got no reply whatsoever and then he posted that the
car is sold.

Oh well

I could have had a new one from rcmart for the same money...

But i have settled on the Xray now anyhow. The TA04 will probably
become a drift car

There was two guys from Launceston down at our track racing their
pro4s yesterday, both running novak ss5800 brushless, one had the
front one way and one had a front ball diff

Dam they are impressive, very fast and totally planted!!

I think my decision may have been swayed...

They also mentioned a guy at their home club that had an xray evo2
and had lots of problems with it and waited something like 2 months
for a front belt to arrive.....

I know the HPI's are damn hard to drive n set. But they r quick. If u can master HPI, the rest would just be a breeze. I let may mate tried my Pro 3 n he was cursing on that piece of junk (well only to him).

I would go pro 4 if you havent chosen yet just for the fact that parts and hop up for the car are easy to get in australia and will become even easier. Not many store deal with X Ray and there has been huge shortage with xray from what my customers tell me.Apart from partsi seen both cars in action and pro 4 is the deal.
