I purchased the float gear in this link: Water Landing Floating Ball + Landing Gear+ Heightened Bracket Kit for DJI Spark | eBay Which adds about 65 grams to the aircraft. Though it is stable in flight, I've noticed these adverse performance issues: The aircraft sometimes continues to climb when the RC stick is neutral and no climb commanded. It is sluggish in response to RC inputs during climb or descent. It is reluctant to descend unless full down stick is commanded and then descends too rapidly. Max motor speed warnings occur occasionally. Has anyone else used the same gear, or similar, and had performance or handling problems? I've talked to Bentguy516 (see video here ) and he has not observed these symptoms, so I am wondering if I have a Spark or RC problem? I would love to hear from you if you have experience with float gear, positive or negative. I plan a lot of over water work and need to be able to recover the drone.
