This kit is designed to fit 220X motors with 16/19mm bolt pattern for 4 inch prop. I'm running mine with UBAD 30A/EMAX 2205 2600KV and DAL tripple. Great combo. This is by far my favorite quad set up right now. Competitive on outdoor agility track and nimble enough for indoor. Great balance between power and control.
The kit only comes with the top and bottom plates. You will need to get spacers/screws from your stash to complete the build. You can use standard 35mm stack height, 30mm for compressed fit HS1177 or 20mm using pico cam. It's all personal preference - I use 30mm on mine with zip tie on HS1177 to top plate.
The top plate is 3mm and will take the punishment. I have broken many other frame with 1.5mm or 2mm top plates in my days and each time it cost me more than just the top plate - usually vtx/cam/etc.
Here is a video of the my set up flying the track carrying runcam2 HD.
Runcam HD2, Foxeer Legend HD or similar style camera protective cage with standard 30.5mm FC mounting spacing. The kit includes two side plates and one top plate which can easily be swapped in/out between your regular top plate with just four screws. The cage was designed to hold the camera down using zip tie which provide tight enough fit to take nice clean video and yet will break off and allow for some forgiveness on head-on hard impact. Two mounting angles are possible ~35deg/~45deg.
In addition to the three plates, you will need to buy M3 40mm spacer (not included in the kti) to complete the build. I bought mine from ebay. I use 3 40mm spacers on my build.
