Idle Ups Or Stunt Mods
Descriptions & Basic First Time Set Up Tips
|
This short description and instructions is for Electric RC Helicopters, and assumes you will be using a "Programmable RC Helicopter Radio" with "5 Point Adjustable Throttle/Pitch Curve" capabilty. These settings are refered to as "Thottle/Pitch Curves" and enable an RC Helicopter to fly the same inverted as they do upright.
"Idle Ups", "Stunt Mods", or "Flight Modes" are a standard set up function used for RC Helicopters.
For purposes here, we will refer to "Idle Ups".
With most popular programmable RC Heli Radios, there are three "Fight Mode" switch positions.
"Normal Throttle"
"Idle Up (Stunt Mod) #1
"Idle Up (Stunt Mod) #2
The following instructions are not cut in stone and are general guidlines for basic "Idle Up" set up instructions and will get you flying through your first maneuvers. Final adjustments can easily be made after initial set up for your flying style and comfort level. Once you get the hang of this, it will come easy for you later on. The key is to just do it, then fine tune later as your flying skill gets better, with practice. There are many opinions out there on how to do this. This is just our way here at DeeTee Enterprises RC Hobbies, based on 20 years of flying experience.
Once you have achieved this basic radio and mechanical set up on your RC Helicopter, and assuming everything else is ready, then you are ready to give it a try, and your set up will enable you to fly the same inverted as you do upright. For beginners, you may be intimdated by this much low negative main blade pitch Just develope a mind set that you will not chop the stick at any time and will be always in control and set down gently, and try the best you can to think before you get to close to obsticles, or get to far away. This basic set up is the best to move forward with your flying skill and not have major set up changes along the way, to slow down your learinging curve.
>>>>Important<<<< Disconnect your motor from your ESC while setting up to prevent any accidental bench spool ups that can be quite devastating, cause serious damage to your equipment, and possible injuries to yourself or anyone close by.
Move your "Idle Up" switch to "Idle Up 1". Once you have achieved "Idle Up 1" set up, its wise to move those same settings to "Idle Up 2" to prevent any accidental switch positions from screwing up your flying enjoyment, and prevent any surprises. Trust me, this can happen.
To begin, there are just a few points that are very important as far as your radio and mechanical set up on your Electric RC Helicopter that will enable you to take full advantage of "Idle Ups" and we will take you through set up on your "Full Pitch Range" or "Pitch Travel", top and bottom, and your "Cyclic Pitch Range" or "Cyclic Pitch Travel" in all extremes first.
Pitch Travel End Points:
With your throttle stick on your transmitter at the center position, check your main blade pitch at 0 degrees main blade pitch. You can eye ball this, but, for the first few times, its best to us a pitch gauge to achieve 0 degrees main blade pitch at half stick. Once 0 degrees main blade pitch is achieved at half stick, move your throttle stick all the way to the top. Check for servo and mechanical linkage binding at that end point. If any mechanical binding, use your tranmitter end point adjustments to bring down total end point travel to prevent servo binding. Don"t use your "5 point Adjustable Pitch Curves" to do this adjustment. Now, move your throttle stick all the way down and check for servo binding or linkage binding at the low end point of servo travel. Once again, if there is binding, lower your servo travle end points on your transmitter until no binding takes place, but still full servo travel.
Cyclic Travel End Points:
With your throttle stick on your transmitter at the lowest position, move your cyclic stick all the way through its end points at all extremes. If your servos are binding at any of those extremes, then use your Ccyclic (elevator and Aileron) ATV's or Travel Volumes to decrease the end points of cyclic travel to prevent the servos and mechanical linkage from binding at the end points. Now, still with the motor disconnected, move your throttle stick all the way to the top of its movement on your transmitter. Once again, move your cyclic stick on your tranmitter to ALL extremes of travle and check once again for any end point binding of your servos or mechanical linkage. Adjust end point travel as described above.
Once the 2 steps above has been achieved, you can switch into "Idle Up" 1 on your transmitter and go to your "5 Point Throttle Curve" adjust on your radio. Switch into "Idle Up 1". Take a peek at your Throttle Curve in Idle Up 1. Adjust the low point to its maximum. (Futaba = 140% -- JR = 100%) Set the center point to about 50% to start. Set the 3/4 point and the 1/4 point to 75%. This can be called a "U" curve. It will enable your throttle to increase in the inverted position so that you can fly around inverted and allow the same flying performance inverted as upright. See the diagrams below.

Once you are confident using your Idle Ups, you can adjust the Idle Up #2 "Throttle Curve" switch position for a higher head speed during the last half of your fligh when your battery pack is not as strong as it was when starting your flight.
Once again, for Electric RC Helicopters, only adjust "Only" your "Throttle Curves" for head speed. Higher Head Speeds produce higher performance, and a bit less flight times. For maximum performance on a 400 size electric (T Rex 450 - Shogun - X400), choose 2800 RPM + for maneuvers and/or 3D style of flying.
