What precisely is there to keep up with? Confusing flashing LED patterns? Unexplained runaway flights? Intermittent erratic behaviour?
A strange set of criteria you have for a Leader of the Pack.
Aye Up Mombassa. I aint really leader of any pack but my own little tribe!
I have 4 WKM machines running virtually everyday commercially and just for fun and all on 5.20 with out ANY issues what so ever. I have just rebuilt my oldest machine which has been hammered to death and was the comfiest pair of slippers ever, I only rebuilt it to double check everything was still ok and yep, apart from new sec's and motors everything is just fine.
We also just got back from a shoot in Peru at 11,000ft in 28ºc which we flew until the packs melted! (well not quite) and never an issue.
Build um right, set um up properly and the WKM is bomb proof. Now the A2 is a totally different story! At the moment I have two bloody paper weights! When they did fly they where crap, BUT I guess I did not have the time to fully set them up before upgrading the firmware which killed them dead for use on Spektrum.
Hexacop. I my just send the A2 back and see what they say. Did you send them back to dealer or straight to DJI?
