Are you kidding me? I havedone a ton of research in the last few days and there are a ton of people very impressed and happy with that radio. I would buy one in a heartbeat except I need more channels. When I was looking at that radio Ithought 6 channels was enough but Iwas soon corrected. I started looking at 7and 8 channel stuff and almost bought an RDS 8000. Then I seen the 9 Channel Aurora and almost had my mind made up right there. Thought I could never use 9 channels but was corrected again. I could go really nuts with my old warbird, apparently.
Glad to hear the recievers are cheaper. I have now found out that most recievers have to be the same brand as the transmitters. Is it the same with the servos?
Yikes!!! I took a look at that servo chart. Do you need to be a physics major to understand it or am I just dumb. I have no idea how to calculate anything from those tables. Would the company be able to give me some recommendations if I give them the size and weight of the plane? Thanks, Ron.
If you go to the discussion thread Igave you about servos, all of your questions will be answered, but let's touch the basics here.
The size of the servo is not related to the wing span or the weight of the plane. It is based on the surface area of the control surfaces, the angle of deflection and the air speed. In that thread is a calculator that allows you to run the calculation very easily.
But, to be honest with you, few do it that way. Here is how this is normaly done.
1) You read the instructions and look for servo recommendations
2) you ask yoru buddy who has a similar size and style plane and ask him what he is using and you use that
3) You start a discussion thread. The title says, " Setting up a<u>
name of your plane </u>and would like some advice. All the people who have that plane, or something similar will join in and tell you what they use.
But the servo calculator tells you what you really need as far as torque and torque, ounce/inches is how you measure the strength of servos.
If you have a 5 pound sailplane that is going to loaf along, you might only need 20 ounce/inch servos.
If you have a 5 pound highly aerobatic jet that will hit 200 MPH you might need 80 ounce/inch servos.
Start the thread and ask you questions. Or go to the servo thread and ask there.
