Do you need servo extensions - I don't know. Do you? Are the servo cables to short? If so, then yes, you will need extensions. That is not a big deal because any three-wire servo extension will work and they come with matching male/female connectors. So, no soldering necessary.

I too wonder about the 9 channel receiver. Why 9 channels? Do you already have it or are you going to buy it? If you are going to buy it, heck, get a 5 channel RX and take it from there. You have a 5 channel transmitter so all you need is a receiver with a max 5 channels. If you could get a four channel, well, that would work - rudder, aileron, throttle, elevator - four channels. If you go with separate channels for the ailerons, then you will use all five channels of the RX and set up the transmitter accordingly.

Dancing pandas are an option. If you really want them, well, knock yer'self out... But, I don't think you need them - yet...

I would imagine that the plane comes with all the horns and clevis's you will need. I might be wrong, but most RTF or Bind and Fly "kits" come with all you will need minus what you don't get - yeah, I know - meaning servos, receiver, battery, and so on.

But, what I would definitely get is another battery pack. That way, you can fly, then when done, set up for recharge, put the second battery in and fly. When you land, maybe the first battery will be charged... and so on . Get it?

And, no, if you are going to fly with ailerons later, then fly with them now. If you need some basic help flying, seek out someone in your area for a little assistance. It sounds like you have the basics down already. But, when you fly, stay in one place and keep the plane in front of you, meaning don't circle around watching the plane.. that means the plane is flying you versus you flying the plane. Understand what I mean?

Best of luck. Keep us up to date.
