Have you seen the RCTimer RCT 800 airframe? It has 14 inch arms that can also be used on a 450/550 airframe. Arms are $15 a pair at UAV Objects.
The RCT 800 is only $61 at UAV Objects. :)
What are the largest size props that can be used with the stock size arms on a DJI F450 quad? It looks like 11" shouldn't be a problem, maybe even 12" (barely).
aluminum = 30mm (the measurement was taken with the arms installed so I couldn't get an exact measurement flush with the flat end, but should be within a couple mm)
DJI = 37mm
Sounds like a cool rig econfly! I put 11x4.7 props on my rig. Flies really nice and super stable. Haven't had a chance to check the flight time yet, been rainy the last few days. I also plan on using my rig for photography (small camera).
I noticed that some of the screws that attach the bottom...
I decided to go for the T-Motor MT2216-11 900kv V2 and the AIMDROIX Aluminum Arms for DJI Multirotors (QUAD PACKAGE).
Thanks for the input guys.
Maybe in the future I can add 4 more motors to upgrade to an X8 configuration.
