hi all,
i would like to ask you guys questions about my new plane CC Lee J3 CUB Piper 3 channel airplane with 380 motor.
the Tx has full control of rudder and elevator, however the throtle only controlled by switch which only can be on/off. probably many of you have seen this plane on ebay lots of the time. i know this is not a proper airplane, but i got this plane as a xmas gift. my questions are:

1. how do i manage to climb and descent? by elevator or by switching the throtle on and off?
2. when hand launch, what the position of the elevator should be? and when to change the position of the elevator?
3. according to your assumption, will the plane fly straight with the throtle on, or do i have to keep switching the throtle on and off to keep my plane flying straight? (remember, only on or totally off, no electronic speed controller)
4. any tips for successful flights?

5. would you recommend parkzone (or hobbyzone) Slo-V as the best choice for beginner? (first time ever)

thank you guys...
