The more equipment that is installed on the plane, the more load the wing will need to take. To prevent the wings from flexing too much, the plastic spar can be replaced with a carbon one.



Materials:

1. Hacksaw

2. Masking tape

3. Carbon rod (5/16" OD or 8 mm)

4. Original spar



Process:

1. Line up the two spars to get an idea of where you will have to cut the carbon spar.

2. Wrap the the location that… Continue

Another simple modification to increase the spar holes strength. I notices that after just a few flights (and a few hard landings) that the spar holes in the wing started to stretch. To fix this problem, I reinforced the holes with fiber washers. (Note that these pictures were taken after I had already done this modification)



Materials:

1. Hobby knife

2. CA

3. Two fiber washers (5/16" ID x 3/4" OD)



Process:

1. Place the spar inside the hole and the… Continue

In this modification, magnets are installed into the wing root. This modification was inspired by the tendency for the wings to vibrate themselves apart during flight. Since simply pinning the wings in place (either mechanically or with adhesive) would not allow the wings to be compliant during a hard landing, magnets seemed like a good substitution. The process for installing the magnets in the wing root is very similar to the process for installing magnets in the canopy (see my previous post,… Continue

This is a pretty simply modification to the canopy to replace the plastic tabs with magnets. Once done, it is quick and simple to get the canopy on and off and, as a bonus, it makes a neat snapping sound when you put the canopy back on. The process is straightforward. (Note that these pictures were taken after I had already done this modification)



Materials:

1. EasyStar RC plane

2. Hobby knife

3. Epoxy or CA

4. Four neodymium magnets (I used 0.25" diameter, 0.125"… Continue
