Foam planes are easy to assemble, fly well, and are easy to repair when you have that “oops!” moment. But what if you could minimize damage from that unexpected meeting with terra firma? Killer Planes has come up with a great solution: The secret is the addition of carbon-fiber rods of various lengths and diameters throughout the airframe. Killer Planes call this crashproofing “Crash Damage Resistant Technology” (CDRT). And although there isn’t a totally crashproof plane out there, Killer
Planes CDRT greatly helps minimize damage. Let’s take a closer look
at these kits.
Included in the kit are a whole lot of carbon-fiber rods and tubes, and a
set of instructions. Because the kits are designed for individual planes,
each kit has a different number of rods, tubes, bars, and plastic plates.
The kit for the Top RC F W 190 that I review here contains 30 carbon
fiber rods and tubes, and I was amazed at the amount of reinforcement
it added, with no areas overlooked. Rods are added to the wing, ailerons,
horizontal stab, elevators, vertical fin, rudder, and (of course) the fuselage.
In my test plane (which is available from Killer Planes), all of the holes
came predrilled. This alone is worth the price of admission as the holes
are accurately drilled in the wing panels, along the full length of fuselage,

and in all the other parts. If you’re not handy at drilling long holes, Killer
Planes will install the kit for you and even touch up the paint. It also offers
different levels of reinforcement, from Max Crashproofing to Supermax
Crashproofing. If you’re handy drilling long holes in foam, you can also
purchase separately drill rods of varying lengths and diameters and all the
reinforcement parts for your particular plane.

One big help was that all the rods and tubes came dry-installed into their
respective holes, which eliminates any guesswork. The recommended
glues to use are Gorilla Glue, hot glue, and contact cement. I used Gorilla

small lever at the front locks the
hatch in place.
Here, you can see that the rods are partly inserted into the left wing
panel and aileron. Make sure the aileron rod doesn’t poke through the
other side as this will bind the aileron.
Here are the carbon-fiber rods for the right stabilizer and elevator
and for the right wing panel and aileron. All the holes in each surface
are already drilled for the rods. The thin rod marked “GAR” is used to
insert glue deep into the holes.
