ng650-2306

Introduction:

With the weather warming up again, I wanted to continue down the plank path by slightly increasing the wing size to fly 3s li-on packs.

Components:

• Sunnysky 2204 2300kv motor Emax 2306 2750kv

• GuanLi 20a 2-3s esc with 2A BEC Furibee 30A esc

• 5v bec (for servos)

• Dollar tree Foam board & pipe insulation

• Frsky R-XSR

• Noxe F4 flight controller (flywoo version)

• Beitian 220 GPS

• Foxeer micro arrow camera

• 2x MG90S servos

• FX799T 200mw vtx

• Buzzer

Conclusion:

This has a dry weight of 225g. With a 3s Li-ion, the AUW is 375g. I have increased the wingspan from 580mm to 650mm to accomodate the larger battery since I still prefer the lighter wing loading. I also have not used r-xsr receivers in wings before, so this is going to be a good range test comparison with the xm+.

The maiden went well. It cruises at around 28% throttle. It took a few rounds of adjustments to find the right reflex. Rolls were good, but not as good as its smaller cousin. Same for all other aerobatics. The rxsr failsafed at around 2km whereas the xm+ failsafed at around 1.7. The rxsr definitely has a bit longer range, but not really that much longer.

It met all my expectations, but didn't exceed any. I think somehow deep inside, I had much higher hopes for this one, but that doesn't mean it was bad. It wasn't a particularly windy day (10-12mph winds), but it was particularly gusty at higher altitudes. It got tossed around quite a bit and I think I probably unfairly gave it lower marks because of that. When I flew the mini AR after, I realized just how gusty it really was since the AR was getting tossed like a wet rag. I'd be really interested to fly this again on a calmer day.

Update 3/18/21 - tried it on 2s li-on packs today and while it flew, the flight was pretty anemic. Had to use very high throttle to fly. Will need to stick with 3s packs.

Update 3/22/21 - I swapped to a bigger motor and 5" props. Weight is now 230g. Power definitely has increased, but so has the noise. I remember now why I don't like these motors as they create a lot of noise in the video (certain ones anyway). Even with the CG moved way back, it still doesn't climb well. I noticed that the chord is the same as the 580mm version even though the width was increased, which was very different than the 610mm version which had both the width and chord increased proportionally. I think I'm going to slice the wings to bring it back down to 600mm and perhaps swap to a 2205 motor instead.

Update 4/3/21: I swapped over to 6" props and went with 2x2s Li-on packs in parallel. It seems to be a much better combo than 3s with 5" props. I think I may stick with this combo. Cruise is around 30% throttle.

Flight Logs:

• 11km (960mah x2 = 1920mah used) | 2s 2p lion | 174mah/km

• 15km (791mah + 803mah = used) | 2s 2p lion | 106mah/km

Update 8/26/21 - Decided to recycle the parts for this into another plane since it wasn't in any way spectacular.
