Motor mounts
I recommend the LR 85 Hyde mount for this airplane. I worked with Merle Hyde on the
application and operation of this mount, having tested all of his mounts on this airframe,
and finding the LR 85 to be the best overall for my composite designs. The motor mount
is important because of the center hinging of control surfaces. The better the mount the
longer the hinges stay tight and free of slack.
Servo's and Linkage
I recommend, for best results, using Futaba™ BLS Brushless servos, or an equivalent.
For elevator halves, use the BLS 651, for ailerons use the BLS 551. On rudder, use a
200-inch ounce servo for the most consistent results.
For clevises on the glow models, I recommend the Tetra™, Central Hobbies™ or MK ™
BB clevises where possible, for all surfaces and Central Hobbies™ Carbon/Titanium
push rod systems. It is important to have as little linkage slack or looseness as possible,
for the best trimming, flying and durable results. Remember, quality servos produce
quality results!
Now lets get to the building
These instructions are specific to a glow engine setup. Some of the building will be
applicable to electric versions, but this manual is specific to the glow setup. The electric
version can be built with a slightly lighter process.
I have replaced the aileron, and rudder clevis arms with a sunken dowel to give the
ability to use Tetra BB linkages. This will give the best results for longevity and slack
free usage. If you choose to use the rudder arm supplied in the kit, make sure it is
installed far enough back so that it does not hit the fin during extreme rudder throws.
For the elevator, in this example, we use the supplied arms. I feel this is the best setup.
