You know you need to get something decent to compete with the others and parts that won't break easily when you misjudge the triple, and you don't want to hand over a ton of cash...you're ready for the BZ-444 Pro.

The BZ-444 Pro is the latest competition ready chassis from BSR racing. Designed and manufactured by Team C Racing with a huge range of option parts such as front and rear metal gear diffs, anodised aluminium motor mount with integrated heatsink, aluminium hinge pin holders font and back, and the absolutely superb Team C aluminium shocks already included. And it's available as either a build it yourself kit, a 17.5 Stock Class almost ready to run or 10.5T Open Class almost ready to run. .

This is an incredibly well balanced buggy and with all the upgrade and option parts available it will suit racers from novices right through to seasoned mod drivers. It can easily be tuned to a variety of track surfaces so it's ideal for racers who visit tracks with diverse surfaces. It is also incredibly simple to work on with only only a few screws needing removal for access to most of the commonly serviced items.

We opted to supply this buggy with a ROAR approved TrackStar 10.5T or 17.5T motor and TrackStar 80a Turbo ESC so it can be used straight out of the box at the many tracks around the world that offer a 10.5T or 17.5T Stock class or as a novice class entry level buggy that can either be sped up when the driver gains confidence with Turbo Boost or a simple motor upgrade.

So if you're ready to take the next leap in a 4WD buggy get yourself a BZ-444 Pro.

Info about teamC gear diff. mesh :

T04041 set up tips :

Because of the small ring & pinion gear sizes combined with the high-power brushless systems used in today’s 1/10th buggies and trucks, there is little margin for error in the gears’ positions. Please follow the tips below for maximum durability and satisfaction.
1. Install two 5x8mm pinion shims (#86000) to both of the center cvd pinion shafts. The first shim should go on prior to the two 5x10 bearings. Then install the 2nd pinion shim after the bearings, as if to sandwich the bearings between the two shims. This will allow the pinion to be seated in the best position inside the gearbox, so that the full length of the gear teeth will be aligned on the same plane as ring gear teeth. Without the extra 5x8mm shim, the two gears will be staggered in their placement, not allowing maximum surface-to-surface tooth contact with the ring gear. That can cause a premature gear failure or break.
2. Apply a small amount of red thread-lock on the first few threads of the pinion screw, to prevent it from loosening. A little heat is all that's needed to remove the screw later for maintenance. Because of the amount of torque needed to tighten and loosen the small screw, it is wise to replace it after bearing maintenance.
3. Next, install two of the 10x12mm diff shims (#TR4057) together on the same (gear) side, to achieve proper mesh.
4. Now trial-close the gear-box with all four screws, to confirm the proper gear mesh. Once you have achieved a mesh that is snug but not binding, you should then re-open the gearbox and apply a heavy grease onto the ring gear teeth. Do not run them dry.
5. After your first trial run and/or race, re-check to ensure proper mesh still exists. In the future you may have to eventually add a third 10x12mm diff-shim, to maximize gear life.

So, BZ-444 pro is a mix between TeamC TC4 and T4 v2. It use TC4 plastic chassis plate and shock tower with T4 v2 gear diff. transmission with T04039 rear gearing housing. TR04 pro have stick battery chassis plate with same rear gearing housing as BZ-444.

If you upgrade BZ-444 with slippers, aluminum damper and gear diff. you will have a TeamC TR04 pro.
If you upgrade BZ-444 pro with carbon chassis plate, upper deck and shock tower you will have a TeamC T4 v2.

Hey Jym,
Great info, got my kit yesterday, it had a couple of missing pieces. The only thing critical is a pair of the cross pins (1.7x11mm) that hold the wheel hexes on. I can get them easier from Amain than HK.
Do you have any idea what the spur gear pitch is? I need to order a pinion. Are rims with the 14mm hexes unusual?
Cheers
Brian

It seems there are "too much" (even in few box it is too much imo because ask for missing parts can be a little hard with HK) parts missing on some cars from HK whatever the version RTR, ARR, KIT. I have read parts missing on Turnigy SCT KIT, body missing on Basher monster truck 1/16, missing wing on BZ-444...

It seems it can have issue with the original 1.6x11mm pin from TeamC. Some TeamC user use clip or 1.5mm hex tools to help when they are on race's day.

Spur gear pitch is 48P.

Thanks Jym,
My kit says it uses 1.7mm x 11mm pins. Amain hobbys has 1.7mm, that may be stronger for you. I had some extra screws, about a dozen or so in the kit. I hope I haven't over done it on the motor and ESC. I've got a SMC 540-4 pole 4500kv and a 160 amp ESC combo coming. If it's to much it can always go into my SCTE.
Cheers

It the BZ-444's manual it say 1.6x11mm spring pin but actualy it isn't spring pin so maybe it is 1.7mm also. It is the only car i have who use pin with less diameter than 2mm.

A 11mm pin in the motor, hard to don't see it before it does bad things.

Nice that they have added screws more, it is same with the Turnigy SCT kit. But if an essential part is lacking, screws more resovle nothing. I have see a guy really unhappy because it lacked too much plastic parts and not only pin. For an ohter one he didn't have manual, so for a kit, make thing a little bit tricky. I have numerised mine for him.

I want to find some clamping hexes, it seems that 14mm rims are not that common.

Yes 14mm is like their 1.7mm pins. I have bought HSP 5mm, not received yet.

I hope 1.7mm pins won't bent because it is normaly for 2mm pin, but 0.3mm isn't too much : http://www.ebay.com/itm/4PCS-Metal-5.../171427508062?

That link goes to some 12mm hexes. I think what's important is the shaft size and the bore on the hex being the same.

Front center driveshaft


Does anyone know where I can find the front center driveshaft? The Team C part # is TU0447. I can't find it anywhere, preferably in the US. But it's been out of stock for months. I can't run without it, Been waiting and waiting, anyone seen where I can get? This is the upgraded shaft that has to be used with the optional ring gear and pinion.
Thanks

Hi,
Is possible install one lipo 2s Into the saddle tray ?

Is impossible to move the Esc to side of motor and install. The battery in the other side ?
