LA Racer
Build - Jim Corbett
I took all the advice and help
offered, it made the project much less frustrating.
Pilot - I used the double faced tape, it does not stick to the rubber
pilot or the cabin deck very well, also added two screws from the
bottom up AND tied him down to the cabin deck with dental floss
(waxless dental floss and colored black with a felt pen, knots
CAed). Thanks Craig for the tip.
Motor mount and muffler bolts - Used loctite on them.
Wing bolts - I replaced the provided ones with 1/4" x 2" hex head black
nylon bolts and blind nuts.
Aileron control wires - one of the supplied had usable threads, the
other did NOT. Replaced with my control wire and clevises.
Used Z-bend connections for elevator and rudder control wires where the
hook to the servos.
Switch - I installed an EMS Heavy Duty switch harness with charging
plug.
Fueler - I installed one of those pivot open and close types - don't
remember the brand.
Landing gear - mounted wheels forward (tried wheels aft , would not
taxi without full up elevator.
Cowling - Marty loaned me the template, it made that job a snap....
thanks Marty!
Glow Plug - The TT R3 was JUNK. after two flights the post wobbled
around and the motor was hard to start. Marty loaned me an O.S.
#8. WOW what a difference!
CG - On advice from Wayne, I used a 6 volt rx pack (5-cell). Mounting
that at the rear of the fuel tank, it balanced right on.
Control throws - factory recommended for 60% dual rate an a bit more on
full rates.
Landing - I still do not have that smooth and bounceless, practice will
get me there.
Canopy - I did not use the double sided tape, yes some fuel is getting
under it.
AMA number on wing and fuse. Name and phone number on fuse as well.
Trimming - Elevator and Rudder are straight. Left aileron was up
about 1/8" Found that the leading edge and trailing edge of the
wing at the center were fine. At both wing tips the leading edges were
fine but the trailing edge of the left wing was down about 2mm, heated
the wing and twisted it, now I need aprox 0.5 mm of up aileron to fly
level. Will heat and twist a bit more some time soon.
Covering - some wrinkles have appeared after it has been out in the
sunlight for awhile, will need to get the heating iron out and fix
that. Several places on the fuse where the wing attaches I have
noticed the covering loosening up, will need the heat gun and some CA
to fix that.
PROP - Pick one, adjust the motor to go fast and turn left. If
you do not get your landings bounce free, you will get to use a
different prop soon.
