3DXHOBBIES Airfoilz Extra 300NX
was a great purchase for me. The kit was not that expensive
the electronics that I purchased were also inexpensive. For
under $150, I had a Battery Ready park flyer that I now have been
flying regularly in calm and in the wind. The stickers were
the only thing I did not like about them, They seem to be a bit heavy
for graphics and you really need to pressure them on to get them to
stick. No big deal but if there was anything bad to say about this
plane, that's the only thing I could come up with.
build takes time. So you better have some patience for it.
the good news is they supply a CD manual that is for the most part
pretty straightforward. If you have any questions, there are
build threads on RCGROUPS on this plane and the other Airfoilz. The
threads are heavily monitored by 3DX as well as other pilots.
only thing that is odd that you might find is the use of Microballoons.
I happened to have some from 10+ years ago, but some hobby
don't carry it. You don't need much and you could probably
away with a couple applications of Epoxy at a time for each wing but
that adds weight. I followed the CD manual but did jump a
times so I could work on something while Epoxy is drying. MAKE SURE YOU
READ THE FULL MANUAL before you start.
All of my Electronics were from HOBBYPARTZ.COM.
Alpha 480 920Kv motor, EXI S1123 Servos, Volcano 25A ESC and the Exceed
2.4Ghz Rx. I used a 1300mAh Blue
for battery but others are flying it also with 1800 and 2200mAh
batteries. I don't tend to fly full throttle all the time and
don't fly long so the 1300 was perfect for me. I chose an
APC electric prop. The Alpha 480 920Kv comes with the prop
and firewall mount as well as Bullets to solder to the ESC. I use DEANS
plugs so I had to solder that to the ESC myself. There is
Alpha 480 1100Kv motor that you can use for this plane as well.
Even with an old spare weak 1300mAh 20C pack I had, I got
vertical and could hand launch straight up. I'll comment about the EXI
S1123 servos, they are REALLY inexpensive, Less than $3 each. You can
get the 213F digital versions for $9, but these analog servos are GREAT
for the price. They have a ball bearing in the top and the centering is
great. Virtually slop free (unlike a set of E-flite servos I have in
another funfly). These are a hidden treasure over at Hobbypartz.
Setup & Maiden
important thing is to NOT mount the battery of cut the slots for the
velcro straps for it until you finish the plane, have all the stickers
on and can then measure the CG. Place the battery on top of
wing at the CG point and see if it will work there. Shift the battery
till the CG is perfect. Center the straps at the center of
battery and place Velcro on the plane, You can then shif the battery
forward/back to adjust CG after maiden. Maybe make a mark where the
leading edge of the battery goes for future reference.
built the plane straight, had my CG adjusted right, my maiden was
uneventful and my trim took only a few clicks here and there.
flight, the plane flew AWESOME for a profile foamie. It tends
flop over in the grass if I land too fast, but the plane can take it.
Just chop the throttle in time and no worries. This
is a blast!!!
