Setting Up and Flying the Avios MIG-17 Fresco.
The MIG-17 by its very nature being an EDF model is not aimed at beginners, having said that it is a very stable and forgiving flyer
that will bring a smile to the face to every pilot who flies it. It does very smooth jet style manouvres and aerobatics and looks
fantastic when doing fast low passes over the take-off strip.
Before flying please ensure that the model balances at the correct center of gravity point as shown on page 2 of this manual. The
C of G point shown is
30 0mm from near the front of the wing in the center. To achieve the correct balance point move the position
of the 6S battery pack fore or aft in the battery compartment.
Recommended Control Throws.
Ailerons:
20mm each way (Expo 30%)
Elevator: 12mm each way (Expo 30%)
Rudder: 15mm each way (Expo 45%)
Flaps: 20mm
Air-brakes: Adjust to full travel without the servo binding.
We recommend that you use either a smooth hard surface for take-off and landing or very short smooth grass. Switch on your
transmitter and check the meter to ensure the Tx battery is fully charged and then plug in the flight battery, wait for the motor/
ESC to go through its arming sequence. If this is its first flight or the first flight of the day carry out a range check. Then do a
control check, check that the control surfaces are moving in the correct direction and with the full movement you have set on
your transmitter, check all switches including rate switches are in the correct position. Once you are satisfied that everything is
working correctly then and only then line the MIG-17 up into wind on the take-off area.
When you are ready to take-off hold a small amount of up elevator then smoothly open the throttle to full power. The MIG will
accelerate quite quickly and due to no propeller torque it should track nice and straight, just correct any tendency to yaw with the
rudder. As this is a EDF model without a propeller at the front you will not get any blown effect over the wing and control
surfaces, it relies solely on forward speed. For this reason the take-off run will be longer than with a propeller driven craft and the
control surfaces will be ineffective until airspeed is reached. Once take-off speed is reached the MIG will smoothly rotate, once
airborne climb out at a shallow angle and allow the speed to increase, retract the gear as soon as you have reached a safe height.
As mentioned before this is not a model aimed at beginners so we will not go into flying in great detail as you should be an
experienced pilot in flying the more advanced
type of models. To start with just get used to the sweet handling characteristics of
the MIG and note how stable and smooth it is. Try the stall, it is very benign due to the swept wing configuration then go and
explore the aerobatic ca
p abilities.
Once you have had your fun and before your battery goes flat think about the circuit, approach and landing. Fly through the
overhead at about half throttle and select gear down, check that all 3 wheels have lowered. Fly a nice reasonable large square
circuit and for your first few landings leave the flaps
and air-brakes alone. Once on approach reduce power and set the model up
for a nice steady descent towards the landing area. Remember, unlike a prop driven plane there is no prop wash over the wing or
control surfaces, also the power is slower to respond. A prop plane when you open the throttle you get almost instant power and
accel
e ration, with a fan model this is much slower . I f you are undershooting the landing area you will need to put power on
sooner than you would with a prop plane. Keep the speed up a bit on the approach as remember you need airspeed for the flying
controls to remain effective (no prop wash). Round out, reduce power to idle and then flare and the MIG will almost land itself on
the rear wheels with the nosewheel just off the ground.
Once you are really used to the MIG try the flaps at height to start with and get used to the handling characteristics with them in
the landing position. You will find them very effective and will give you lovely scale like landings, just be careful if you are having
to land in a crosswind.
The same goes for the air-brakes, practice with them at height before using them on a landing approach.
We hope you enjoy your Avios MIG-17 Fresco and if you haven't already tried our other models in the Avios range then we
