Hey guys what are the major upgrades of this car from the original B44? I know this has probably been discussed but it is a hard topic to search for. Any help is appreciated.

Hi

A new track nearby has just opened up and i need some pointers. The track is indoor clay, some areas are bluegroove, some are rougher. Dust will build up during a heat.

The track has decided on Gold Bar Codes in the back but front tires are open. Do you have any tips on front tyres to give more turn in than gold bar codes? I find that the car pushes really bad in the slower corners and needs corrections with the throttle to rotate properly.

just wondering if anyone has tried finding a gear diff that fits in the b44.1

What setup changes have you made to help?

Clay suburbs, switches, bk bars or taper pins might be options.

I would go lower. I know on the SC10 4x4 castle doesn't recommend anything larger than the 3800kv. I do not know the weight from a B44.1 to a SC104x4. I have not gotten my B44.1 yet.

I am at 13/62 gearing on my 4x4 truck and it flys with the 3800kv

I put durango diffsin my b44and I loveit! It wasn't easy though. Basically you will need a complete set of durango diffs,outer bearings, and pinions. I machined the durango pinion off of the shaft, and cut the b44 shaft down to the required length. I was going to c clip the pinion on but the b44 shaft was very hard to machine because of how hard it was. So I wound up laser welding the pinion onto the shaft. (Kind of sucks because if the pinion bearings need to be replaced I'm sol, I'm not too worried though cuz those rarely go out.) Then I had to machine some spacers to make the durango bearing fit in the associated case. Which is the blue plastic spacers in the pic.

i'm for trying new things . Why not just get a Durango buggy:blush:

I would love to but there is no support for them at our local track, plus it was a fun project.

vito 11-09-2011 10:46 AM

the b44.1 is a fun car. i need a higher kv motor like a 7700 kv set up it this to high?

Getting back into the RC Game.
 
Hello,

I haven't raced or worked on an RC Car since 1996. I am trying to go with a great setup. Now that I am an adult with a stable job and good income I can finally afford not to scrimp :) but that doesnt mean I dont want to buy smart.. I essentially want to get back into racing with a viable setup..

I have read nearly all of the pages for this topic and have picked up little tidbits here and there. I have been doing alot of research on alot of cars and trucks. I choose the b44.1 because of the local hobby shop parts availability. I wanted a 410 v3 but didnt want to be side lined waiting for parts.

my questions are...

Is there anything I should upgrade during the build? Ceramic thrust diff balls etc?
Any greases better than others for Diff building? Lubing? Aluminum a-arms better or stick with stock ones?

LRP Sxx V2 TC spec - x 12 8.5t - fast yet controllable? I am a novak but researching this LRP setup looks promising.

Ready 2s 4200mah 35c - Enough punch? Should I up to 5000mah+?

What is a good servo to use? One that wont strip out and will have enough torque for those rough sideways landings.. I will be using a Futuba 4PL

I know that's alot of questions so any help will be appreciated.

Thanks.

Great choice mate they are great buggies..
I use high temp bearing grease, any auto shop + cheap
Stick with the plastic arms. Better to have them break than some thing else closer to the chassis,
I run the same LRP setup other than i run a comp spec not TC spec and its bullet proof.
Maybe get a battery with at least 45c rating as 35c is getting pretty low..Most of the saddle packs now are 60c.
I run a Foobar 9252 which is an old school plastic geared 6kg servo i had on a chopper.. Works great and havent stripped a gear set yet..
Ive been racing mine since February and only broken one front arm(huge crash at full noise) 2 ring gears in diff( set diff at 1/8th turn like in the manual,kept stripping, now at 1/4th and i've not touched it since.)

Umm... shouldn't you adjust the slipper to allow slipping to protect the drivetrain, not diff?
