When I went to the field the first time with my Taranis after setting it up at home I got the motor running, noticed it wasn't quite working the way I thought it would AND the controls were a bit off as well SO I fiddled with it a bit. Finally got the motor curves set up correct, the flaps, the flap rates, the throws on the elevator, ailerons and rudders AND I took off. Flew for about 2 minutes and my 24 ounce gas tank on the TGY 52 ran out. Evidently, I'd fiddled with it a bit more then I thought.
Landed, refueled, checked the batteries because I forgot their value was now on the screen of my transmitter and flew the rest of the weekend, with that plane, with no hassels. The next 4 planes re-setup quicker.
You'll love it.
Oh, and I'm blind as a bat too now. Had lasik and just as my eyes were settling down and I could SEE with them, they changed. Back to Glasses, Bifocals. ARGGGHHH Distance is great with the glasses, my neck hurts with the bifocals so if I'm typing on a computer like now, I take them off. For anything under a foot I generally put readers on so I can look straight at it without looking down my nose. Trying to hang a picture on the wall? Not with bifocals you don't. Gettin old sucks.
