1rcracer- with a one way of any description you should have plenty of entry speed off power.
The most important thing once you are there, naturally is getting the amount of speed and enough rotation from the back of the car to get it round the corner, and out the other end.
Too much speed, and obviously you will be off the racing line... Finding a balance of grip and speed is where we are now in any cornering situation.
I would experiment first with laying in the top of the shocks a little, to see if that helps.
If it doesn't, I would then look at changing springs, and if there is a big change needed to the springs, look at changing oil and possibly the pistons too.
You may also want to try changing your droop settings, but these can make very big changes to the cars behaviour, and sometimes even aid lifting an inside wheel on the entry or apex...
so play with that setting very
Only change one thing at a time each time the car goes on the track to see any change taking place, or you will be chasing the setup...
If the grip is low full stop, I would suggest either a spool or a diff up the front, as with lots of off power speed and no grip, you are asking for one thing.... trouble! lol
If anything in low grip situations, you want the drivetrain "drag effect" to be helping you when you let off the throttle, to help the car scrub speed and stand a better chance of rotating well mid corner.
You wont get that with a one way.... Drag brake dialled into the ESC if its a small track may help.
If there is no grip, you just have to slow the car down, plain and simple and wait until you have passed the apex before you can use the throttle.
But!!! If you are using drag brake, that may just be masking an unsuitable setup for where the car is being used...
