Impulse RC Apex HD 5" DJI O3 conversion kit

thingiverse

This is a conversion kit I designed that makes the Apex HD 5 inch frame able to fit the DJI O3 Air unit system. The slot for the GPS fits a Beitian BN-220T. The antenna mount is very sturdy due to the additional reinforcements. My modified side plates leave enough room for the thicker cam mount. As a plus you have more headroom in the front where you can place a big cap or other components. The cam mount was designed with a front bumper that absorbs the energy of the impact, so it breaks before your cam is damaged. No props in view, even with 4:3! Furthermore, I made a modified top-plate for countersinking the roundhead screws because I disliked that a crash always leaves a screw mark in the lipos. And because lipos are expensive I designed a lipo protector for a Tattu R-Line 4.0 1300mAh 6S lipo that fits perfectly the top plate. You can fiddle your lipo strap through the long tunnel and snug the balancer plug into the smaller cavity. Nothing on this quad wobbles around, so you can tune your filters aggressively according to Chris Rossers strategy. Beeper and Crossfire was installed with white Tesa sugru, which I can recommend very much for FPV stuff (I get no comission for that ;-) ). It´s a moldable putty like silicone mass that glues everything together and hardens after 24h. After that it´s hard but still a bit flexible. And in addition is watertight and electrically insulating. I printed everything in Flashforge PLA pro. I recommend 0.12mm layer height, 3 outlines and 15% infill. Kudos to Stuart_D89 and duerro for making the air unit holder and the cam plates, which I took as a basis for my remix. EDIT: Top plate v2 out now with improved strength, symmetry and XT60 socket
