I do get why it would be called rocket racing drone (a race can be done in a straight line aswell 😂) but I question pretty much everything I see in this page. Takeoff weight of roughly 1.41 kg (including lipo), no motor KV mentioning on the whole page. over 400 km/h,... maybe it can reach 250 up to 320 max as props with a pitch of 8 will slip alot.. it also depends on weather etc... unless they provide proof it will do over 400 km/h. theoretical its possible.. I think it will get boring quite fast while I do get that it can be an interesting project for some time.
Yea it seems sketchy in a review by captain drone it has a gps but on the page theres no mention of that also no mention of a recommended battery weight and capacity even worse the reciver probaly wont have a elrs target so theres no way to flash to a newer version
