This mother board is the newest version with the updated three capacitor voltage regulator circut. It came flashed with opentx 2.3.5. I used this motherboard to turn my Jumper T16 gen 1 into a pro, hall V2. I had a firmware flashing mis-hap with my computer with the original motherboard due to a bad usb port corrupting the flash. This was not on Jumper or Grayson Hobby. So with the new mother board I'm back in the air flying. Before flashing new opentx from Jumpertx, make a copy of your models and settings within opentx companion. I did this and successfully transfered my models including a flybar collective pitch heli mix back to the T16 with successful results.

I have not used this board as of yet because it's a spare for my T16 Pro. Grayson Hobby has been fast and efficient getting all my orders out the door. I have total confidence in purchasing from this outfit !
