Yet to buy one of these, look relatively near easy to fly, 4 blades sure are pure fun
Found this one of many Quad Sims For IPAD, a whole 99 cents definitely worth a check, some parts feel abit static too easy but manuvering at the start found abit challenging out of the gate. Indoors and out with challenges to manuver thru even tubes, land slightly off center on slot wooden tables and all crunches down, quite amusing. Several view offerings make for fun rides, gads I'm horrible but addicted already.
Again feels abit static at the start, but wait till you start manuvering, then the fun begins!
