Some helpful techniques and tweaks.

 Repairing broken plastic parts>

 I was able to develop a method of fixing broken helicopter parts so that they are stronger than the original. They weigh only a fraction more than they did to start with. My whole whisper heli weighs only 4 grams more. If you do the job neatly the parts look real good just a little different in appearance. These repair techniques work just fine on any helicopter or hobby part made of plastic.

The reason I bring up this repairing thing is I believe it is impossible to learn or even to continue flying without crashes and broken parts. For some helicopters offer the advantage over other r/c aircraft in that you do not have to fabricate to rebuild, just pay the cash and replace the part! But for some of this the money thing is a problem and if you have the right attitude, breaking a part can actually be part of the fun of the hobby with these repairing methods.

1. 1. Plan out the area to reinforce around the broken joint(s).
   2. Roughen this area with coarse sandpaper, file, or knife.
   3. Glue parts at joint(s) with C.A.
   4. For high stress areas like landing struts, form a music wire to proper length and shape, place into area tucked into it wherever possible. Tack with C.A. [ Note> use C.A. accelerator for tacking only. ]
   5. Place strips of DAVE BROWN or equivalent carbon fiber strands along length of part over break joint(s) and C.A. in place. You may have to use black thread to hold shape. Go whatever direction with the carbon fiber that molds to the shape of the part. Mixing different directions with the carbon fiber is stronger. C.A. liberal amounts into the carbon fiber and onto the plastic and/or music wire.
   6. After several hours drying time flex part to check for good adhesion. You may fill the carbon fiber areas with mixture of microballons and C.A. or aliphatic resin, then sand and apply black felt marker. The parts look good with just the carbon fiber if you shape it right. You can plan the black thread as your finish layer, which is what I did on my landing struts. I wound it around and around the length of the part for a real even surface, then soaked the thread in C.A.

 The CCPM issue when building the Eco Helicopter >

If you have a JR transmitter sold in U.S. you can have the CCPM turned on by sending it back to Horizon Dist. or better yet to:

Radio Control Service Center, 7750Convoy Ct. , San Diego, Ca, 92111 (619) 560-9622 for faster service. Only cost about 15 bucks and it gives you European class control.

So plan on using this feature if you can before building the kit to save weight and get better control response, less play and moving parts.

 To fix bent tail booms from boom strikes >

Get a socket from a socket wrench set that just fits inside the aluminum tube and bang it down through protecting ends with wood block and/or soft material.
