Cons: Other batteries that fit the X4 are too tight in this 252. Some shaving/sanding/scraping with a knife helps.(wrap with clear tape to make a pull out tab) Props are not on very tight (not enough of a friction fit) So need to use some glue on the shaft. 2 of the 3 screws that hold the body will not fully tighten. Only received 2 rubber nub feet.(use a dab of glue so u dont lose the others) First flight had severe drift backwards and crab left. (finally able to rectify)
Pros : 25 grams no bat, nice lights,V202 controller works, as well as stabilization reset (sticks to bottom left) All lights flash when bat is low. I would say it flies/piros like the v202, nice banks. I flew this and then the x4, and since i am an aggressive flyer(no box flyer) i prefer the v252. I find that the x4 with my flying style indoors drifts too much and i crash more. Lots of people dont like the slow piro of the v202 but i dont have a problem indoors ( v212 is barely manageable inside the way i fly, lol). If i want to navigate carefully indoors i use the x4, but if i want to fly inside i use the v202 and now v252.
Results: i would give it a buy again. Future durablity of body i hear is weak but i try not to crash too hard. Even though i have a few crashes, only one slight fracture in arm.
Cheers, your results may differ...
