RE: A Beginers Guide to RC.
I just purchased a bird (not a plane) and I cannot get it to fly! It says it is for beginners, but I think I am missing something.
The manual is easy to read, but I still don't get it. I can flap its wings, move the tail, but it just slams to the ground. Does anyone have any idea what I am doing wrong OR what I am not doing??
Does the controller just work on AA batteries??? Special batteries or just regular over-the -counter AA??? My controller has new batteries, but will only control the bird if it is plugged in. Do you need to charge the controller w/the charger? When I plug it in the light is green. I have no idea.
I need the basics.
Thanks!

Side force generator? Well, that is anything that generates a side force. In what context are you using the phrase?

RE: A Beginers Guide to RC.
So, I am new. This question will make that clear.
I have 2 trainers. NexStar and a Cessna 182.
The Nexstar came fully loaded.
The Cessna I had to assemble. Which is going great.
I am now at the point where I need to purchase the radio. My question:
It says it needs "4 channels, 5 servos".
I am confused by this. If I purchase a 4 channel radio, a 5 channel receiver. Will that work?
help.....
Thanks all

RE: A Beginers Guide to RC.
The Next star is the glow powered RTF, right? That comes with a radio, so you have a radio.
You need servos, an receiver battery and a receiver. You can use an 8 channel reciever with a 2 channel radio. Non-issue.
Based on your note, the Cessna needs 4 channels on th radio. R/E/T/A I presum. 5 servos implies that you will have two of the servos on a Y connector going into one channel on the receiver. Most likely the aileron servos. They are probably too far apart for one servo to drive the ailerons, or you need the extra torque of one servo per aileron.
When you connect them you will have to mount them in such a way that they move opposite each other and you will have to trim them mechanically on the plane. You can not use the reverse feature on the radio to reverse one of them.
The alternative is to get a computer radio, which is what I recommed for everyone, and put the two ailerons on their own channel.
Low cost choices would be Hitec Flash 5SX - $159 with servos, receiver and bat
or the Futaba 6EXAS for about the same.
You can look at them at www.towerhobbies.com search on Futaba 6exas and flash 5SX
If you have the bucks, then the Futaba 7C and the Hitec Optic 6. With servos and receivers these would be around $240 I think.
Hope that helps.

Your post was outstanding but it was aimed at one audience only. That being the glow heads. I fly glow exclusively however the electrics are passing us by. Take a look at the model magazines and you will see for yourself.
The new breed of RC flyers are young and want to do there own thing. It is my opinion that they are seriously hurting the image of RC modeling and regetting our hobby back to the toy store.

RE: A Beginers Guide to RC.
If you buy something like a Futaba Skysport, you will get a 4 - channel transmitter and a 7 - channel receiver. But, that is not the issue. Using 5 servos in this case means that there will be 2 servos for the ailerons. You can connect both servos with a Y - connector and plug it into the receiver and still only be using 4 channels of the receiver. If you get a computer radio, it will allow you to use 5 channels of the receiver but that will be extra expense to accomplish the same task.

RE: A Beginers Guide to RC.
Thanks for the quick reply.
The NexStar is a glow.
So is the Cessna.
I understand the concept now.
The Cessna has 2 servos for the ailerons. One on each wing. Now that I look more closely at the directions, it is obvious that the servos are mounted opposite.
I will take your reccomendations to the store.
I have a few electric planes. I bought them for pre trainer pratice. Cheep and easy way to learn before making the switch to glow.
Thanks again.

Thanks a TON Aeajr.
What are your thought on FM vs. AM for transmitters/recievers?
Can you convert an AM to an FM by simply switching out the crystal?

Here are answers to your questions, and things you didn't ask but might want to know anyway.
AM vs. FM
AM is fine. I had one that came with my first RTF sailplane and had no problems.
FM is better based on lots of technical stuff. Same as the sound on your FM radio in your car is better than the AM channels. If I was buying a radio for long term use, I would only look at FM. If an AM came as part of an RTF package, it would not bother me.
Receivers:
Dual Conversion FM receivers are generally better than single conversion as it
does more to filter out stray signals and other garbage. There are receivers with DSP, digital signal processing that claim to be as good as the DC receivers, or even better. I can't say they are wrong but I don't know.
Range
Be aware of range and how far out you are likely to fly your plane. This is
partially a function of how big your field is and what you are flying. Range is more a function of the receiver than the radio. So check the rating on any receiver you buy.
Here are some thoughts:
Indoor flyers will no likely exceed 500 feet and 300 is probably enough.
Slow flyers, small parkflyers, say 36 inch wing spans and below with speed 280
class motors and below, are probably OK with 600 - 1000 foot range. More is better
For two meter sailplanes and larger faster parkflyers, as
well as small to medium size glo planes, half a mile/2500 feet, would probably
be OK. The sailplanes tend to get high and the others are fast enough to eat
up ground quickly.
For larger glo planes, 3 meter plus sailplanes you want the 1 mile class of
equipment.
There is no such thing as having equipment with too much range, but a three
meter sailplane can exceed a half mile because it is large enough
to be easily flown that far away. You don't want to be flying at the edge of
your equipment's range. Weak batteries, interference and such can shorten the
range resulting in you losing control when you seem to be with the working
range of your equipment, so when in doubt, bump it up some.

RE: A Beginers Guide to RC.
I started out with the Lt-40 and it was a very good trainer! I still have it too. http://www2.towerhobbies.com/cgi-bin...&I=LXFG19&P=ML Also, I think that the os .46fx is better then the .40la. With a 12x6 prop or 12.25x3.75 prop you will be set, and to even do some hovers a little... hehe... Very nice thread!

RE: A Beginers Guide to RC.
I just wanted to thank you all. I have found a great field with great members. I have now found a Mentor.
The local hobby shop teaches flying for free. GREAT GROUP OF GUYS.
I went out on Sunday and flew my glow for the first time.
Thanks again.
I cannot say that enough, and how important it is to find a good mentor.

RE: A Beginers Guide to RC.
One more question.
I went flying for only 15 min. What is the best way to discharge the batterys without a discharger.
Will turning the unit on until it is fully discharged reduce the life of the batteries?

RE: A Beginers Guide to RC.
What battery are you asking about?
Motor battery? I just run it down till the ESC cuts it off
Radio battery? I leave it charged. Will run down on its own just sitting. If you do turn the radio on, put at least a couple of the antenna sections up, but not all of them. Also, do this in a basement if you can. Remember you signal has the opportunity to shoot someone else down. How far are you from the flying field?
And, I would only do this every other month or so. Today's NICDs don't have the severe memory issues the older ones had. If they are NIMH, no cycling is needed on a regular basis. Once a season or twice a year would be plenty and maybe that is more than needed.
