ng580-2726
Introduction:
I didn't want to build another plank, but I was just too curious as to how it compares to the previous wing when it comes to speed.
Components:
Dys Samguk 2207 2600kv motor
Amax 40a 4s esc
Dollar tree Foam board & carbon fiber spar
TBS crossfire nano rx
Noxe F4 flight controller (flywoo version)
Beitian 220 GPS
Generic camera
Emax ES08MA II Analog Metal Gear Micro Servo x2
Vivafpv 600mw vtx
Buzzer
Conclusion:
250g dry. I seem to be able to make wings lighter than planks (even with a center fuse). 25g extra seems to be significant, so we'll have to see how it handles.
The maiden was ok, but I was a bit skeptical of it after the first flight. It was very twitchy until I completely readjusted the servo links for more precision. After tuning it a bit, it flies a lot better. There is still a bit of bounce back, so there is going to be more tuning necessary. It flies very much like the previous planks, except with a ton more power. I love the extra power as it pretty much assures a successful launch even in adverse wind conditions. This one is really growing on me, so we'll have to see how good I can get the tune.
Update 7/15/21: After flying this one back to back with w60-2726, I have come to the conclusion that I prefer planks overall. The w60 is lighter and a tad faster, but the plank does have a better tune while the w60 feels more raw. I think if I did a v2, I would definitely tune it a bit more and make some changes to the elevons to tighten up the handling.
Update 10/14/21: Tried putting a 5.5" prop on there and it went over 160km/hr, but smoked the ESC and possibly the motor as well.
