I switched from the G Pro wireless to the 305 wireless, also used a lithium battery and a AAA battery instead of AA. Little plastic converter (for even lighter weight). I also have a 3d printed battery cover with the weight reduction holes in it, that comes in the mail tomorrow, pretty excited for it! I loved the G Pro Wireless as well but I couldn’t get consistent 1k hz polling with it.. :/ but for a g305, I think the shape fits my hand better and it uses the hero sensor, now it will be lighter than the G pro Wireless, and it was a fraction of the cost.
