### ⭐⭐⭐⭐⭐ Complete Awesomeness
*by C***I on 1 May 2023*

I really love this aircraft it turns a mediocre beginner pilot may be better than the other people I fly with but a terrible pilot just beginning on this journey makes me look like on all out pro doing tricks roles spins loops even this little flat spinny thing that it does with full rudder I haven't said that I have crashed it at full throttle going straight plowing nose down into the ground of course it did break the nose off (doing tricks as a novice and didn't get the safe back on)but it was a clean break I was able to get the foam glue and glue it right back on and didn't need some beat after that It has plenty of power it'll get you out of sticky situations because of having enough to do so I did change out the props but the regular props work fine they're just quite expensive compared to the alternative The only reason. The batteries you can use an 800Mah like I did there are other alternatives basically a one cell battery it has a high enough c-rate will work I did have some in my box from RC cars that only ones that didn't work cuz they didn't have enough high enough C rate discharge and it started cutting out the motor as if the battery was low so I haven't said that a higher enough output battery should work as long as it's a single cell with the correct plug you will be fine This thing flies awesome was easy to set up All I did was put the preloaded model from my menu in and bind and go it was ready to fly in less than 10 minutes. Little rudder style winglets are there and they just stick in to give you the lowest profile inside the box for easy carry which I love however mine do fit a little bit loose I didn't put much stock into that and just immediately started flying it I haven't lost one in flight yet and I have done some crazy stuff when I did plow nose first into the ground though it did pop both of them off as well as the battery door other than that never had them come off at all so I don't be too concerned if yours fit very loosely cuz of course mine hadn't flown off but if you wanted to you could just put a piece of you know the the fuzzy side of velcro on there and that would give you a little tighter fit if you're worried about it off it seems too too loose. I originally had the larger version the blue one and I sold it to a buddy just to get him in cuz the planes he were trying to fly were kind of older and not as easy so I let him fly this and then ultimately sold it to him I ended up getting the red one to try which is smaller to see what the difference was mostly it allows me to fly in a much smaller space I can fly right outside of my house The larger one flies pretty much exactly the same but of course the turns are a little bit wider and such , The bigger one flies on a small three cell pack so of course it does seem like it has a little bit more punch but I don't think there's any lacking of power on this plane on one cell at all it is definitely phenomenal I have seen some info about it having bushings instead of bearings on the motor so that might be a long-term effect that wouldn't be as great whereas the larger one has bearings it will probably last longer but I'll keep flying it and figure that part out.
