ng610-2423

Introduction:

The 580mm ng2423 was very maneuverable, but the scaled up 650mm version lost a lot of it. I decided to build something in the middle to strike a balance between wing loading and maneuverability.

Components:

• Sunnysky 2204 2300kv motor

• GuanLi 20a 2-3s esc with 2A BEC

• Dollar tree Foam board & pipe insulation

• Crossfire Nano rx Frsky rxsr rx

• Noxe F4 flight controller (flywoo version)

• Beitian 220 GPS

• Foxeer micro arrow camera

• 2x JX PDI-1109HB servos

• Vivafpv 600mw vtx FX799T 200mw vtx

• Buzzer

Conclusion:

210g dry. This one was more challenging. It flew initially, but the CG was very different than the 580mm version (about 1cm further back). Even with the correct CG, it is not as nimble as the smaller version and tends to stall easier so you need to build much more speed for loops, etc. Aside from that, tuning was also an issue. It seemed to have some drift after auto tune and required some more I gain on the roll axis. After that, it flew much better, but it seems to rock left and right on certain auto modes like RTH and 3dCruise.

Update 3/24/21: Increasing the P gain moved the rocking from left/right to a up/down motion instead. After turning on the artificial horizon, I can see that the horizon is not set properly, which probably means the board is not tuned to be level. I'll need to tune that part of it.

Update 4/3/21: Rocking was fixed by a simple adjustment to the pitch setting (2-3 degrees). Flies

Flight logs:

• 15.4km (947mah used) | 3s lion | 61.49 mah/km | Flew into a thermal for a few mins (more efficiency)

• 10km (779mah used) | 3s lion | 77.9mah/km

Update 5/31/21: Updated this for testing with the Inav 3.0 RC. 3.0 is amazing for those who don't want to tune rates the old fashioned way. This flies a lot better, but there are still quirks which I think may still be related to the level trim.
