FORTY5
ASSEMBLY INSTRUCTIONS
1. Insert your stack bolts into main plate prior to frame assembly
2. Assemble keys in Main & Bottom plates first before inserting arms last
3. If keys are too tight to fit in holes, use some Wet & Dry sandpaper (while wet) to sand back the keys just enough to get a snug fit. (This occurs because the thickness of carbon plate can vary +/-0.20mm).
4. If you are really struggling to get the arms into place, connect the arms together and with some Wet & Dry sandpaper you can sand the top of them back until they are a snug fit. If for any reason the arms are a little loose between the keys, you can try adding a slither of electrical tape.
5. If you face the arrow of the middle/bottom plate towards to the back of your quad, you will gain a little more camera to stack clearance. Aslong as your esc will fit this way (Foxeer Reaper 45a and 60a slim wont)
TUNING RECOMMENDATION
- For a clean, quality build you should have no problems using the Karate (New Spice) Tune and Karate Array filters.
- However, the below is a safe tune, which may help if you have a noisy build or something isn’t quite right. The below tune which is basically Karate PIDS with some slightly less aggressive filters.
- The below tune needs to be applied to BETAFLIGHT DEFAULTS. If you have already loaded Karate/other settings, you will need to revert to defaults before loading this tune. Make sure to add your RC link preset too.
This tune was using an MPU6000 using 8k/8k Gyro/Pidloop
