Another Wing Attachment Method
Here is another way to connect the wing using $.87 cabinet latches. The screws are really just like pegs glued into foam using CA. If you can find nylon versions that would be even better because they are lighter. I could not find them in the USA. I think they come from the UK. That said, the ones I installed are great. These really lock wing halves together quite well and hold it against the fuselage.




Here is video of plane after installing 240 Hobby King LED surface mount lights. These are simply powered by the 3S on board regular power system pack. I added a on board switch to turn them off and on.
Skysurfer Night lights -- final setup (1 min 44 sec)
Twilight Night flight Skysurfer with 240 LEDs (7 min 11 sec)
The LEDs are mounted on thin copper strip with adhesive tape on the back side. The first flight with the LEDs mounted on the wing surface caused severe tip stalling. After repairing the nose three time from crashing I trenched the wings and mounted the LED strips so they did not protrude. Each strip was covered with 3M storage tape. The twilight video shows how nice the plane flys with the lights installed.

RICH MODELS 52" wingspan ELECTRIC TRAINER
This is 52" high wing trainer sold by A-K Models. It's only $55 plus $9 to ship. Instructions were typical for Chinese ARFs -- useless. It's wood construction and covered. I had to modify it so it could accept smaller electric servos. There was no servo tray. The battery hatch was useless so I had to add one to the bottom like Eflite Alpha.

I am on my second because the first one was crashed when I was training someone.

Summary
All frustration aside it is a good flyer.

Frustrations come from missing parts and instructions are absolutely useless. Couldn't tell what was missing when received because there is NO parts list provided. You only find out when you build this. This is electric and instructions show a servo tray for nitro with full size throttle servo. All servos shown in the kit instructions were full size. And, there is no servo tray anyway. You have to make one. LOL funny how these kits are basically a airframe with you figuring out how to put it together.


WING ATTACHMENT
The directions show the wing attaches with rubber bands. It screws on but it uses puny M4 x.70 30 mm NYLON screws that stripped when installed. I switched to steel.

Missing parts included NO servo steering linkage and NO aileron horn brackets [couldn't attach aileron pushrods]. Back to the hobby shop for steering linkage and aileron horn brackets. You have to have built planes before. Funny, the price is right, but the kit...Continue Reading
