Snake bite
okay guys,
to get you through those first few loops
1. first get comfortable with the heli being at a distance and doing circuits at altitude. Particularly practice diving slightly to gain as much speed as possible as it flies straight. Not necesarily a steep dive, just about 25-35 degrees down so you gain heaps of speed.
2. The lowest part of the dive should still be about 15-20 meters from the ground.
3. do your absolute best to get the tail directly behind the fuselage. (easy with NORM gyro, needs your input with HH Gyros)
4. When comfortable doing these high speed passes then simply pull aft cyclic and hold until the chopper has completely looped then use forward cyclic to continue forward flight.
5. If you do not move the collective from where it was when you entered the loop, usually about 75%, then the heli will still loop without a problem. Simply tighten the loop by pulling more aft cyclic if you start losing altitude too much.
6. This will get your confidence up in the heli being able to loop which will inevitably lead you to the next step..........
REMEMBER - ENTRY SPEED & ALTITUDE!!!!
7. Reducing the pitch while looping should occur so that the transition from positive to negative pitch (o degrees pitch)happens when the heli is vertical, and the most negative you decide to pull should be at the crest. Start with small inputs until you get more comfortable.
8. In an effort to begin inverted straight and level, and extend the inverted section of the loop, make sure you keep the airspeed on and always have a BAIL OUT PLAN- roll,flip, or half loop.
9. Gradually decrease the airspeed to hover inverted, remembering your bail out plan.
More info.
- A half hearted loop is a disaster in waiting - go for it 100% only. Sometimes its best to fly the high speed passes until you feel very comfortable with the speed and then go for the loop on the pass that "just feel right".
- If extending the inverted section to hold altitude or even hover, you will need negative pitch to be setup.
- Semi symmetrical blades need more negative pitch.
- Without a governor, or if the governor is switched by the transmitter stick position, requires another pitch curve which increase the throttle at below 50% stick position. (keeps revs up - not required just for a simple loop though)
- Look at getting a header tank for extended inverted flight.
good luck,
sorry go to go........
