I recently aquired a PN DSM2 board and love that I can use my spektrum radio with it. The only problem I am having is adjusting enough brake into the unit. I have the brakes up to 100 on the radio and full 85 on the ICS adjustment. Even the drag brake is at full. Running a 50t PN motor it is a rocket but trying to get it slowed back down for the 180 corners usually ends up in a push after after a high speed section.
Is there another step for the esc to learn what full throttle and full brake is??? I can only find info on how to bind the Board and Radio but setting endpoints it just seems to learn on it's own??
I don't think there are any endpoint adjustments on the board itself, you have to adjust the transmitter to match the board. I have 5 cars with PN DSM2 boards in them, all work fine. I generally don't set the reverse endpoint on radio, but for the forward endpoint all of the boards I have tend to be around 105-115% to achieve max throttle. This is with DX3C/DX4C/DX4R transmitters. I think the reverse endpoint should be similar.
I also run a 50t (bushing) PN motor and have no problem slowing down. The motor by itself has a fair amount of drag. Have you tried playing around the ICS V. Inertia and Drag brake settings to see if they are actually doing something? The effect should be very noticeable. I generally run with a slight drag brake (-1 setting in the ICS), and almost never need to brake. Higher drag brake settings (-3 or higher) make the car stop too quickly for me.
Does the car actually brake when you apply brake from the transmitter? Maybe there is a throttle curve/expo/ABS or some other transmitter setting that needs adjustment? Which Spektrum transmitter are you using?

Thanks for the help, I could not find anything on-line about radio set-up. Bought this used and searched for instructions but not much I could find. I set the radio end points to 100 and after binding it seemed strange that I did not need to set the ESC to the radio like the 1/10 scale ESC's. The ICS setting full brake I still was only getting a soft coasting brake. I'm am using a DX3rPro and all the fancy ABS and other stuff is turned off on it. After reading your post I did try turning the end points up and can hear the motor RPM increase drastically over the 100 end point setting. Seems about 140 brake and 115 throttle was about where the motor topped out. The extra 40 percent brakes side sounds more like what I was needing. We run on a smaller track and our last layout had a 180 at the end of the straight. 2/3 down the straight I would have to go full brake to get it to slow down to make the turn. Improving my set-up and tire combo I am sure will help the high speed 180's too. Can't wait for the next club racing now!!!
Over all feel is so much smoother than the the standard stuff. Really like running the car now with this board / radio combo. Driving the track is like cutting soft butter now instead of a brick pulled out of the freezer. LOL
Another issue I seem to not be able to conquer. Steering servo can not be adjusted to full lock. Bind the board and radio at 100% settings and after about 125% the servo will not drive any further. Still about another 1/8 to go each way before the end of the rack hits the stops. Adjusting up to 140% and the same result with the only difference being the servo stops before the wheel is full lock. If you push the wheels with your finger to get full lock then the servo will move it back to 1/8 from full lock. With the car off the servo turns fee full lock to full lock. Replaced servo gears and front end parts to make an almost slop free steering with the same results. Does not seem to matter witch to bock I use. Cleaned the steering pot with electric cleaner.... kind of out of idea's to get a full lock adjustment.
