The sunny ones will make your spark flip over in sport mode if you turn too fast, the motors wi shut off so what ever is under you and how far away is gonna matter
I use the 4 float balls , the plastic landing gear then attachments for balls weigh a lot . I never have good luck over water, it really confuses spark if you’re not traveling at a steady speed . If you’re hoveri g over water, you’re spark will eventually land in it
It looks fairly thick , I like the wraps , but I feel like I'm gonna have a hell of a time, lining the stickers up right An it will turn out like an 8 year olds Xmas toy
I think the battery straps are more to prevent mid air fall outs, but they may have held it in this type of fall also, I got mine on eBay for $3, it snaps onto sparkys arms on both sides of the battery
When you first lift off, go straight up and look towards you want to go, try and get higher than the tallest structure in that direction, and set your RTH altitude
There are YouTube videos of people connecting two go4 apps to Spark at the same time but I'm not sure if two can control the camera , I've never tried either
That dome is causing your signal to redirect away from you, anything conclave and metalic that gets behind you or your RC is gonna throw signals all around
