B44.1 handling issue please help

richie. · #1 06-01-2015

I'm fearful of the old man chucking the hobby in because his car has become a handfull leaving us scratching our heads! An example is when driving down the main straight, if you back off the power on the bend the back end will just spin out 180 degrees on you very quickly. It's a similar story all around the track. I've tried all sorts of individual changes one at a time but nothing seems to shift the balance of over sensitive back end and steering. Is there anything wear and tear wise that could have led to this?

Excessive binding somewhere, check with wishbones up and down? Have you checked all bearings?

Seem daft but you haven't got the drag brake turned up too high

Not so daft..! Does sound like a braking issue to me.......

Maybe with a one way in the front, but no-one runs them these days do they?

Thanks for the replies, I will double check the bearings and wishbones when I get in, the drag brake was set at 20% so we reduced it to 10% without notable difference. However I did question the esc (SP reventon pro) as it may well have happened when this was fitted. No one way fitted, could it be worth rebuilding the diffs? I also run a b44 and i can't say rough diffs have effected my car in this way?

Would have help you out if you at teesside car club ..

Need to check all 4 corner that not binding if u remove the drive shaft away from outdrive.

what tyre you using at the minute ? yellow mini spike or mini pin
I recommend using same tyre front and rear at same time when new in packet .. if using rear worn tyre and new tyre on front which will causing issue such as spin out on corner. lesson learned in past

Make sure you have the latest firmware installed. Lots of oddness with some of the early ones.

And tbh, I run 5% drag at most. 20% is masses!

Thanks guys, running yellow full spikes as per norm for our polished wood floor track, always run evenly ran tyres. Took out drive shafts and no binding at wheels.

I believe it has the modified software installed which runs great on another guys car but I don't think I can select 5% drag as it rises in 10% incriments

You might need the upgraded (?) program card or bluetooth, I can do mine in single units iirc
