They won't do it any more! I just called to see If they would replace mine and they told me They were out of stock
And didn't do that any more...

That's why it's best not to post it over the web. If only a few call then they are more likely to do it. Just PM people from here on out. Special people like me.

Default Sorry for the dumb question, but...

can you get away with using AE diffs and idle gears? Had to ask. I think AE's diff material has to be the best out there. Also, Frank said sometime back that HPI was going to change the mold by adding material to the steering knuckle so the servo could not throw all the way. Has HPI done this yet?

Thanks! Yeah i believe there is a titanium color, look at the last page of the BMI thread there is a pic of one. And yes all BMI sets come with shock towers.

Hope this helps

i've just finished building my '05 edition, overall it went together ok but I had a few issues...

the bad:
- the new aluminium servo mount/transponder holder wasnt designed with the futaba s9550 in mind, I had to dremel out a fair bit of metal for the servo wire connection.
- no more out of the box free drivetrain, it's taken me about 45 mins with the dremel to get something thats even remotely free....
- the new aluminium bevel/input shafts are noisy! and its quite hard to get a loose mesh for a free drivetrain
- the bearings seem to be oiled a lot more heabily than I remember my other 2 pro4 kits, and one of the steering knuckle bearings is very notchy... I'll have to give them a flush out and re-oil them to see if that helps with the drivetrain

the good:
- not having to do the upper deck mod is sweet
- the new shocks are awesome, very smooth, and easy to build, on the first attempt all 4 shocks had identical rebound. the only issue is there is no oil drain hole like in the older ones, which i found quite useful
- the box setup is vastly different to the older version, it will be interesting to see how it goes out of the box

Hi, could someone please help me out with the ackerman positions on the carbon plate??
I know that the effects of each hole on the handling have been posted before but there are alot of pages and the search function is not helping me out at all. Thanks for you help. Jonathan

domo, what part of the gearboxes did you dremel?

The bearings have grease in them, soak them in turps overnight to flush out the grease, then put a couple of drops of light oil in them.

Providing the gearmesh is set correctly the gears won't be that noisy when you actually run the car on the track.

i have run the AE gears in my pro 4 and havnt had any problems with them, and they seem to me a little stronger than the HPI ones. I run open mod and the hpi ones dont last all that long with a spool on a tight track.
At least not for me

the inside of the gearboxes were binding on the bevel gear, not sure if the moulds have changed or the delrin outdrives caused this...

are you refering to the one piece input shaft/gear? if so, i cant see it being quiet on the track, its bloody loud, ive been running it in with an old motor at 3v hoping it would quiet down, but the note hasnt changed even after 20mins and the drivetrain still isnt very free, at this stage im thinking about going back to the old input shaft and gears...

if youre refering to the old gears, yes both my other cars are near silent on the track, and on the bench...
