Safety Precautions!
Please read this section and follow all recommendations!
1. Do not fly in strong wing or bad weather.
2. Never fly the model in crowded areas where there are lots of people, automobiles on the
road or power lines overhead. Do not fly near full-scale airport.
3. Make sure that you have enough open area for flying as the model can travel at a high rate
of speed and cover a lot of area quickly. Initial flights should be made in an area with a
minimum size of a football field.
4. This model is not recommended for children under the age of 14.
5. When charging the LiPo batteries always charge them on a non-flammable surface and
monitor the charge process. Improper charging of LiPo batteries is dangerous and can lead
to a fire!
6. The is made from EPO foam and plastic. These materials are flammable and can be
damaged by
h
igh heat. Never leave your near a heat source or in an automobile.
7. Do not attempt to catch your while flying.
8. Never leave your unattended when ready for flight.
9. When preparing for flight, always turn on your transmitter first and make sure that your
throttle is in the off position prior to plugging in the flight batteries. Failure to follow this step
may lead to unintended motor start and damage to the model.
Illustration of Assembly
1. Open box and carefully unwrap all parts.

2. Applyasmall amount of epoxytothe
right stabilizer3. Put intoposition on the verticalfin.
4. Check that it isat 90 degreesfromthe fin. When the epoxyhascured drill a3mm holethrough
the verticalfinfromthe left side. Drill aholeinside the stab toaccept the 3mm carbon tube
reinforcement.
5. Applyalittleepoxytoone end of the tube and insert it through the finand intothe stab.Drill the
left stab inthe appropriatelocation and slipit on the carbon tube and glue tothe fin.

6. Check that the stabilizersareat 90 degreestothe verticalfin. Mixsome5-minuteepoxyand
applyan even coat tothe root of one wing panel.
7. Insert the aileron servowirethrough the holeinthe fuselage and then pushthe wing panelinto

24. The Center of Gravity range for the is from about 2-7/8” to 3-1/4” back from the panel line
on the bottom of the fuselage near the front of the wings. Adjust the position of the battery to
achieve correct balance. Never attempt to fly a model that is not correctly balanced.
Preparation before flight
25. Set throttle to the lowest position 26. Turn on the transmitter
And set transmitter trims to neutral.

27. Connect the flight battery to the ESC. After ESC initializes check that the correct channel is
controlling each control surface and that they are traveling in the correct direction when
commanded. Example: right stick moved to the right and the aileron on the right wing moves
upward while the aileron on the left wing moves downward.
28. Adjust each control surface to its neutral position by mechanically adjusting each clevis.
Recommended control throws for Mig-15
Elevator
Low Rates 3/8” Up and 5/16” Down
High Rates 9/16” Up and 1/2" Down
Aileron
Low Rates 3/8” Up and 1/4” Down
High Rates 1/2” Up and 5/16" Down
After initial flights adjust the control throws to best suit your flying style and ability.
Check before flight
1. Make sure that your transmitter is fully charged. Conduct a range test of your radio system per the
manufacturer’s specs.
2. Check all flying surfaces for correct direction of movement, correct amount of movement and for correct
centering, adjust as required.
3. Fully charge your flight batteries prior to flying.
4. Hand launch into the wind and land into the wind.
Flight Adjustment
1. On initial flight climb to about 75-100 feet and see if any trim is required. If the model rolls to the right, apply
some left aileron trim to level the wings. If the model dives, apply some up elevator trim, ect.
2. Landing should be made into the wind, reduce the throttle to just above idle and keep the nose level or a little
high allowing the airplane to sink toward the ground. Apply a little throttle as the model reaches an altitude of
a foot or so, this will slow the descent and aid in the flare to a smooth landing.
Have Fun
We hope that you have many pleasant
flights with your Mig-15
