Confused on Radio.... 6 ch or 7 ch or higher?

Confused on Radio 6 ch or 7 ch or higher?
Both web stores are selling the same plane, but one site is saying you need a 7ch or higher and the other website is saying you need a 6ch?
The plane has 11 servos, how could this be with a 6 ch radio?
Can you help me out on this one?
Thanks
Bobbart

Below are the two sites:

Very easy, ailerons now often have separate servos (but only one channel). Same goes for flaps, and rudder+nose wheel steering. Many planes now have separate servos for each elevator. Throw in a vectored thust and the number of servos can go up by 2 or 3.Here is the list of normal channel numbering
CH1 ailerons
CH2 elevator
CH3 throttle
CH4 rudder+nose wheel steering
CH5 retractable landing gear
CH6 flaps
CH 7 auxiliary channel often used as a special function like bomb drop, lights or with mixing like nose wheel steering, flaperons, thrust vectoring etc
CH8 auxiliary channel (bomb drop, lights, special mixed channels like those listed above)

It sounds like you are very new to the RC flying hobby. If you plan to stay in it for a while, it will pay to buy a radio with more channels AND have memory for numerous different models.
Enjoy!

bobbart Apparently my advice on a radio in your "other" radio thread, " Need some help picking Radio, Battery and Charger " was no good?

I think the issue here, is that you had know idea what the cost of Quality radios are, and the prices scared the hell out of you! When they say RC plane, boat, car, etc the C stands for CONTROL! I don't know of many people, myself included that would want to fly with someone using a $40.00 radio flying a jet at 100MPH.

For what you say you want, you will need at least a 7 channel radio, 8 would be better. But it will cost you!

You need to kick back and start doing some serious research. Use the Search this Thread or Search this Forum. Because the planes you are looking at are foamys, start your searches there. http://www.rcgroups.com/foamy-edfs-377/ Chances are there may be a thread on it, with tons of info. See what they are using! Look at the attachment and see how they hook-up things.Read the build threads.

You are going to have to do lots of reading. All the guys here at RCG are most generous with there aquired knowledge, I know that from personal experience. But no one is going to spoon feed someone who doesn't make an effort to find the info himself.

If you have some high geek points look at the tr9x and the frsky modules...

tr9x mcu is flash-able from USB, very stable distros for it and its' 75usd shipped from hobbypartz....16 models on tap and the rest saved to computer with er9x distro

frsky MCUs hop EXTREMELY fast (THIS IS VERY VERY VERY IMPORTANT) not one instance of lockout in over 2yrs, 20usd each and have telemetry built in each rx and add ons for more functionality

Don't get a cpu or radio where you don't know the performance of the components

Just remember this... You get what you pay for and sometime less than what you pay for if you don't do enough research...

Ill vouch for the turnigy 9x. Had it over a year and not a single issue. Have flown about 8 different planes ,a 500 ,and 600 heli with no problems. I know many guys will point the finger at a cheap radio but ive also had jr,spektrum,and aurora 9.

Not in this hobby, some of the most expensive stuff really does not put out relative to stuff that's half or even a quarter of cost.

It's always best to look at components and good to look at performance for the price...

Bobbart,

Based on your original question, I've figured out that you have misrepresented yourself as an experienced RC flyer. Plenty of people have offered you some great advice but if you want to keep looking for the cheapest RTF edf jets on the market, just buy one and try to fly it. When you crash it it will be a combination of the cheap quality and your lack of experience. Once you have crashed several hundreds of dollars worth of planes you'll either give up the hobby or start listening to the good advice people have offered you.

I agree on the Turnigy 9X, and other same clones, series..... they are incredible value, and once upgraded to use FRsky RF module/RX they form a bullet proof system!! For approx $120 (Tx with one Rx)

But you also "MUST" (as in must for the ultimate result) do the firmware mod to use ER9X (or some Open9X system) because that then turns your $120 8 channel radio into having all the features (bar telemetry, sort of), and MORE, than ANY priced TX has.
With ER9X you can also run 16 channels, for a total cost of about $180.

If you do really want telemetry than it is best to use the FRsky DHT-U TX module, which has a data display on it. Or there are firmwares that send telemetry to the TX's LCD screen, IF you mod the TX to be able to do that.

You will need a bit of electronics nouse to optimise the T9X for all the above. Or get someone to help, or do it. I keep thinking I should build up and sell them ready to go... for something like $100 more than cost (labor time). Which is till sub $300 for an incredibly awesome RC system!
