Default Associated B44 weight reduction

Hey guys I was wondering if anyone had some ideas to reduce the weight of my b44. I am running standard kit car with novak gtb/novak 17.5 velociti, ip4800 lipo, spektrum z590 servo, spektrum 3000 receiver and amb pt. The car is about 100 grams overweight and everyone is much lighter than me. I know I can get lighter speedies/motors/servos/screws etc. I am after some recommendations so i get best bang for buck and also how much weight I will save. Cant really believe what info the manufacturers tell me as they reckon the tekin rs weighs more than my gtb and I know this is not the case.

Help please

Thanks
Luke

Sure is strange, most are required to add weight.

What weight is your B44 coming in at?

You do not need to lose any weight, especially with those Lipos. If anything you will need weight to grip the track on straights & turns. Sometimes more weight can win a race against a lighter competetor.

But I believe the Novak motor is much heavier than a Castle brushless, & If our really desperate take off your wing & undertray.

Are you running you're ESC on the same side or opposite as the motor? If you put a Novak GTB on the opposite side of the motor (swap the ESC and receiver from the "stock" recommendation) it balances the car, so weight really doesn't matter. I've never really even weighed my B44, we run an open mod class where weight isn't checked, only size dimensions. Weight isn't a large issue in 4wd mod, just run it the way it is as long as it handles well. If you're car feels lethargic, its probably because you're running a 17.5 :P. Try boosting the timing on the motor.

I already have my car setup like that. It is not a balance issue and the car runs great in mod. I occasionally like to run stock and the car is too heavy to jump the way I like it and also lacks acceleration. Any suggestions for lightweight servos/receivers/esc/motor would be much appreciated.

Are you trying to shed some of the weight on the B44 because of a requirement from a class?

Or is it because it feels heavy during "jumps?" Most jump handling is done through the shocks, but sometimes making it jump-friendly ends up compromising handling while not jumping.

It's a compromise...

So why are you trying to meet 1600 grams?

Yes tom I am trying to shed the weight to comply with stock class rules of 1589 gms + Personal Transponder. Whilst I am over this limit by 100gms and the car handles great. I am also at a disadvantage against other cars that are lighter. They clear our major jump easier and tend to get up to their terminal speed faster. Most other b44's in my class are at least 60 grams lighter which is having an impact. I know I can go up in spring rates/shock oils to make the jumping better but it is the acceleration that is my main problem. Also the track is very bumpy and stiffening up suspension results in poor handling on the rest of the track.

Now dont get me wrong here the b44 is a great car and I am winning races. I just feel that a little weight loss would improve my laptimes and make me more competitive.

If it's a bumpy track i'd say 60 grams won't matter unless you are a very acomplished and consistent driver, you may be, I don't know.
I'd say suspension set-up abd tyre/insert choice will have a bigger impact. Acceleration is all about traction, especially if it's bumpy.

It is a bumpy track and driver has yet to accomplish a major race meeting.

Perhaps the driver could shed 60 kgs, I think that would be a major achievement!
