I made my own very simple anyone should be able to make it, I wasn't going to pay the prices to buy one they are ridiculous in price. I got a sheet of plywood cut it 4 feet by 4 feet (or whatever size u want) I drilled a hole in each corner to run a lag bolt through I'm using some about 5 inches. On bottom side run a nut down then a flat washer then put bolt through hole from underside then a flat washer and nut on top side, do that to each corner. Reason for it like that is so you can raise or lower each corner using the bottom nut and tighten down top nut so plywood is sandwiched between. I glued a bubble line level on each side in the middle between the two bolts so there is a level on each side to be able to level the pad( not necessary for just a launch/land pad to be precisely level but if it is calibrations can be done on it as well) I then painted it with plastidip from Walmart it's dirt cheap so it has a rubber like coating. I also put LEDs on it with a battery (looks cool at night and it's fun to tilt camera down from above and land fpv using the LEDs on the pad lol) but not necessary. If you wanted a folding one cut it in half and put some hinges on the bottom side could even put a handle so it can be easily caried while folded from like your trunk to launch site etc.
