The Parkzone SU-26m comes neatly and well packaged.
Whats in the box:
(1) SU-27m
(1) Charger
(1) 1s 110mah lipo
(1) Wire landing gear
(1) Spare prop
(1) package of AA batteries
Whats not in the box:
(1) Spectrum TX (DX5, DX6i, or DX7)
The Build:
The entire build takes 10 seconds... just snap the landing gear to the bottom and your done. It takes longer to install the 4 AA batteries into the charger so I recommend you do that first as it takes 30 minutes to charge the lipo. To make CG you may need to remove a littl glue around the motor (inside) or add a small nail to the tail.
Center of Gravity:
Is 30-32mm from LE of wing. I used 2 tooth picks and a block of foam to make a CG machine for her. Shifting the lipo even a little causes huge changes in CG. This step is very time consuming. Once you find the sweet spot, mark the lipo location to easy later flights.
Binding:
I used my DX6i so the binding is easy. Just plug in the lipo and then turn on the TX while holding the trainer switch forward. Look into the nose of the plane and when the flashing light goes solid your bound to the SU-26.
Please insure you have already set up your TX for a new plane before binding.
Report Card:
Good:
- Easy build
- Nice looks
- Larger capacity lipo then the Vapor/mCX
Bad:
- Slightly underpowered, climbouts are slow
- Charger is iffy...mine claims full charge after 2 minutes!! Just leave the lipo on her for 30 minutes to be safe.
- Weak props
- Difficult to make CG. (I removed a little glue from around the motor and then added foam safe CA inside the tail)
Flight Report:
Weather Conditions:
- 4 to 7 mph winds
- Sunny

Maiden:
I realize that the instructions are specific about her being an indoor or outdoor flyer only with CALM winds...but I couldnt resist. I took her out and ran her down the neighbors driveway for a nice ROG...good idea as she will ROG however the winds were a little heavy at the time and this plane gets pushed around to the extreme making her very twitchy!! I managed to break a prop. (the prop screws off in a counter clockwise direction).
After replacing the prop with the included spare I went out in the backyard with a freshly charged lipo to try my luck on the golf course. I hand launched her this time and she was off and flying. Surprisingly she is fast for her size, roughly 10 mph at WOT!! I managed to fight the wind which made for a very tense flight!! I amanged a few rolls but was unable to pull off a loop due to the wind as she would just blow down the field while maintaining altitude.
Report Card:
HL: Easy, WOT and let go.
Glide: NA (too windy)
Rolls: Fast
Loops: NA (too windy)
Inverted: NA (too windy causing too much twitchy behavour)
Speed: 10 mph
Landing: Non-event
Beginner: No, need to be familiar with aelirons first as the response is immidiate
Summary:
CG IS CRITICAL! Surprisingly fast and manueverable for her size in level flight, however climbouts are disappointing and loops didnt happen from level flight. Alot of fun to have something capable of sport flying in such a tiny package. She requires more space then the Vapor (I tried to fly her in my living room...bad idea as she will eat up a 20x15 living room in seconds unless your in a high alfa) due to her speed. Keep an eye on the rudder, on hard landing I noticed the rudder would shift and have to be recentered. The Charger has issues, you might need to open it up and check for bad connections to ensure a full charge. Without the full charge you wont be able to gain altitude.
WARNING: The motor mount will work loose after a few nose in's...especially if you removed any of the white glue to help shift the CG. I used a little foam safe CA to re-attach mine, however, IT ATE THE FOAM!! I now have a hole in the bottom of my fuse!!
