Thought I'd share progress on a replacement for my heavy lift Trad heli for larger camera work.
Current Specs:
1.23m Carbon octo frame as the base starting point (from fpvhobby.com)
8x Turnigy G46 550kv motors (running just over 1kw each)
8x 60amp escs
8x 17x5.5 CF props from rctimer.com (soon to be replaced with 18x5.5s)
2x 5s1p (paralleled to 5s2p) 8000mah Turnigy 30c lipo
APM 2.5 w/ Ublox GPS
Custom CNC cut PDU from dual layered pcb
CCBEC pro for voltage regulation
3DR telemetry
Changes to date:
Custom CNC cut black delrin motor mounts with tapped mount holes (also allows LED strip mounting)
Custom Machined prop adapters (6mm mainshaft with DJI style bolt mounting on top)
Additional CF CNC cut receiver plate
Additions to come:
ZYX camera stabilization along with 5D2 camera mount (to be modified) from foxtechfpv
Custom landing gear using 1m thick 25mm OD carbon tubes
Dual camera switch and 5.8ghz downlink
So far:
I got it hovering though it needs signifcant tuning. it was actually too light to tune at 16.5lbs all up (lift off at about 1/5th throttle), I strapped a 5lb dumbell on there to get it flyable. Still working through PID basic tuning. More to come.
