Prime Tundra Plug N Fly Instruction Manual

6. When you have completed a satisfactory range test, return to the model and the flying area. Face

the model into the wind and stand a few paces behind it, do a final control check. Disarm the motor,

ensure the gyro switch is in training mode, and the rate switch is in low rates, you may also need to

hold in some up elevator if the grass is a bit long. When ready, smoothly open the throttle up to full

power, slowly ease off the up elevator if you have some in as the model accelerates. The model will

accelerate quite quickly and the gyro should keep it running straight and true, when the Prime

Tundra has enough airspeed it should lift off into a steady climb all by itself. You may need to help it

take-off with a small dab of up elevator, especially if the grass is a bit long.

7. Climb out steadily to around 100-150ft then throttle back to about 50-60% power. Before it gets

too far away, initiate a gentle turn either left or right back towards the take-off area. In the training

mode, the gyro will limit the amount of roll, and the gyro will also help to hold the nose up in the turn.

One of the things beginners struggle with in the early stages of learning to fly is "Orientation", this is

the ability what is happening with the model and which way it may be flying. For this reason, do not

fly the model too far away, or too high. Another thing to remember is that when the model flies

towards you the aileron/rudder controls will appear to be reversed. As an example, when the model

is flying towards you and you initiate a left turn, the model will turn to its left, but to you, the model will

turn right. This takes practice to get used to, but it will come with time, so make good use of the gyro

stabilization in the early stages of learning. A good little tip here is, if you want to straighten the

model up as it flies towards you, then move the stick in the direction of whichever wing is low. If as it

flies towards you the right-wing drops (model is now trying to turn left), push the stick to the right to

straighten. If the left-wing drops (the model is now trying to turn right), push the stick to the

left.Tundra has enough airspeed it should lift off into a steady climb all by itself. You may need to

help it take-off with a small dab of up elevator, especially if the grass is a bit long.

8. You may at this point need to trim the model to fly in a straight and level. At about 50%throttle the

model should fly, hands-off, straight, and level, it shouldn't be turning left or right, or climbing or

diving. If it is gently turning to the left, move the aileron trim to the right a bit until it flies straight, if it is

turning right, then move the trim left. If it is climbing, move the elevator trim up towards the top of the

transmitter until it stops climbing, if it is diving, then move the elevator trim down. If the model

appears to be flying a little bit sideways (crabbing), then it is most probably being caused by the

rudder trim. If the nose is pointing slightly left, then adjust the rudder trim to the right, then of course

the opposite if the nose is to the right. You may then need to readjust the aileron trim to get the

model to fly straight.Do these trim adjustments a little bit at a time and allow the model to settle in the

newly trimmed position before adjusting it anymore.

9. Now that you have the model trimmed nicely for straight and level flight, experiment doing gentle

turns left and right. The gyro will help with the turns, but if you can, try and hold in a little bit of up

elevator as you are turning, take this out when you straighten up. Always try to keep the model

upwind and in front of you, never let it get behind you and downwind. The height you fly at is

controlled by the amount of power you are using and not by the elevator. If the model keeps gaining

height, then close the throttle a small amount until it stops climbing. If it keeps losing height then

open the throttle a little bit until it maintains the height you want to fly at. You may find that in some

conditions, especially sunny days when the warm air is rising, you may have to constantly adjust the

throttle to maintain your chosen height..
