Extreme Flight LEGACY AVIATION Turbo Bushmaster Manual page 5

A few tips to ensure success:
1. We are very pleased with the level of craftsmanship displayed by the builders in our factory. Through
hundreds of grueling test flights containing maneuvers that no aircraft should be subjected to, our
prototypes have remained rigid and completely airworthy. Having said that, it is impossible for us to
inspect every glue joint in the aircraft. Take a few minutes and apply some thin CA to high stress areas
such as the aileron servo mounting trays, landing gear mount, anti-rotation pins, wing and stab root
ribs, etc.
2. Having survived the journey halfway around the world while experiencing several climate changes, it is
not uncommon for a few wrinkles to develop in the covering. Fear not! These are not manufacturing
defects and are easily removed with a little bit of heat. Use a sealing iron to go over all seams, stripes
and sharp points in the covering scheme. You may want to apply a drop of clear fingernail polish at the
tip of all sharp points to prevent them from lifting. To remove wrinkles, use a 100% cotton tee-shirt or
microfiber cloth and your heat gun and heat the covering while gently rubbing the covering onto the
wood with the t-shirt or cloth. Be careful not to use too much heat as the covering may shrink too
much and begin to lift at the edges. Take your time, and a beautiful, paint like finish is attainable. If you
need to repair any covering during the life of your aircraft, the colors are:
- White/Red/Black/Charcoal/Silver color scheme:
Ferrari Red #23, White #10, Silver #91, Black #71, Pearl Charcoal #77 (Oracover Colors)
True Red-#HANU866, White-#HANU870, Silver-#HANU881, Black-#HANU874, Pearl Charcoal-
#HANU846 (Ultracote colors)
- White/Midnight Blue/Cub Yellow color scheme:
Cub Yellow #30, Dark Blue #52, White #10 (Oracover colors)
Cub Yellow-#HANU884, Midnight Blue- #HANU885, White-# HANU870 (Ultracote colors)
3. DO NOT SKIMP ON SERVOS! Your aircraft is equipped with very large control surfaces that deflect up to
45 degrees. A lot of servo power is required to prevent flutter and to maintain the required deflection
for maneuvers. We absolutely recommend the use of METAL GEARED servos with a minimum of 300 oz.
inches of torque.
4. Use a high quality epoxy for installing the composite control horns and hinges. We highly recommend
the use of Pacer Z-Poxy 30 minute formula. We have used this glue for many years with zero failures.
We also use the Loctite HYSOL brand epoxies with their very convenient application gun. If you need to
clean any excess epoxy, we recommend a paper towel and denatured alcohol.
5. Your aircraft is built using very modern construction techniques and is very lightweight for its size. As
with any high performance machine, regular inspection and maintenance is a must. While
disassembling your aircraft after a flying session, pay close attention and inspect glue joints, linkages
and loose covering to be sure the airframe is sound. A few minutes spent doing this will help maintain
airframe longevity.
6. We recommend the use of blue Loctite thread locker when installing fasteners into your aircraft.
