Thanks for the heads up on twisting the stock props! Now I have a ton of spare props cause I kept buying new ones that sucked..was heating them up to try and put more pitch into them and ruining them. Didn't realize all you had to do was twist them. No more uncontrolled dives for me! With the J-3 motor it'll go as high as I want....was up higher but brought it down so I could see it on my iphone....lol!
