OK, let's define RTF:

Plane is already built
All electroncis are installed by the factory
Final assembly is 1 hour or less
Includes motor/engine
Includes radio
If electric, includes a charger
If electric, includes 1 or more batteries

The most you have to add would be batteries for the transmitter, if it uses disposable batteries.

That's RTF.

The ONLY 4 channel RTF I have seen in the electric space is the Begin-Air

Begin-Air/Wing Dragon Sportster - RTF - $180
Have not seen one fly in person but it looks interesting
Both sites have video - Video at second links is MUCH Better!

Photos and video (slow download)

I can not tell you if it is a good product as I have never flown one or seen one flown.


Now, why 4 channel? Most of the electic world RTFs are 3 channel. They fly well and you can have a wonderful time with them. Then you have a wide selection.

Below I list electric planes, parkflyers and e-gliders for beginners. Some
come ready to fly, some are almost ready to fly (add your own radio gear) and
some are kits. All of them are electric. Whether you are finding your first
plane or looking for that more advanced electric, you should find something
here to peak your interest.

I don't recommend two channel R/T electrics, so you won't find any on the
list. They can be very easy to fly and can be a lot of fun, but they can also
be very easy to lose. A three channel R/E/T is a better choice as a first
plane, in my opinion.

If you are totally new to RC Flying, these articles may be helpful in
understanding how these planes fly

MORE ADVANCED PLANES

After you master a starter plane, you can move on to one of these more
aerobatic and 3D flying electrics. Here are a few planes that would be lots
of fun and would represent a real challenge. Most have videos associated with
their links.
