Default RE: Extreme Flight 88


ORIGINAL: EXTREME FLIGHT

Right on the money Charles and Joe. A few extra minutes spent during the assembly process adding a little CA to high stress areas can really add to the longevity of your ARF. I always mention this in the manuals, but for those who have overlooked it here are some areas to pay attention to:
-Add CA to all servo mounts
-I always run a bead of CA around the joint between the root rib and the horizontal stab sheeting as well as the rib which holds the elevator servo. I do the same with the wing root rib and attached sheeting.
-Thin CA around the anti-rotation pins in the wing and stab.
-I usually thin some 30 minute epoxy with denatured alcohol and seal the edges of the elevator servo arm slot.
-Thin CA to saturate the cowl mounting tabs.
-CA on any fuselage joints that appear to need it.

Like I said, this only takes a few minutes but really adds to the durability of your aircraft. I usually end up putting several hundred flights on aircraft over a couple of seasons before selling the airframes to local flyers. Many of them are still flying and holding up great.

Another area that is often overlooked is regular maintenance. We must remember that these are high performance machines built very light and just like a racecar or motorcycle they need to be properly looked after and serviced. I always pull the cowl and look everything over after the first flight sessions to be sure everything is secure. When putting the plane away after a flying session I always check my kinkages and servos to make sure everything is tight and secure. Every 20 flights or so the cowl comes back off and I have a good look under the hood. There is no reason these planes won't last for many seasons with just a little TLC.
As a full scale pilot for a major airline I can attest to what Chris is saying. The same is true for full scale planes, inspections must be done even if nothing is wrong or suspected wrong. It is called preventative maintenance, it saves lives in full scale planes and it will save headaches and your wallet in RC planes.
