Of the many 3D maneuvers in the pilots repertoire, the blender is probably going the most visually violent. Done effectively, it’s positive to wow the spectators however make certain your batteries are strapped in! Here’s the way to execute it.
The Flat Spin to a Blender
Master this maneuver in 4 straightforward steps
We just lately mentioned uniting upright and inverted spins. This month, let’s construct on this kind of maneuver and take it one step additional. Advanced aerobatic pilots are all the time in search of mixtures of parts that, collectively, can type new and revolutionary aerobatic strikes.
Years in the past, throughout the freestyle occasion at the Tournament of Champions in Las Vegas, Nevada, I used to be watching Quique Somenzini mix a flat spin with a blender whereas recovering at a really low altitude. Watching him carry out this mixture was merely beautiful. At first, the plane entered what everybody thought was going to be an unusual upright flat spin. Then his mannequin rapidly transitioned to a rolling vertical downline, the place he then carried out the blender, which contained an abrupt transition to an inverted flat spin. If you might be in search of one thing new to attempt, this can be a notably demanding maneuver that’s positive to please.

BEFORE WE BEGIN
For you to expertise success, you want the required aerobatic talent and your plane have to be correctly arrange. This combo requires pretty giant management surfaces, coupled with giant floor deflections, in addition to the correct middle of gravity (CG). As a place to begin, start with the control-surface deflection quantities, exponential settings, and the CG really useful in your mannequin.
With respect to control-surface deflection, the entry spin in addition to the transition into the inverted spin throughout the blender would require wherever between 35 and 45 levels of control-surface deflection for the elevator, rudder, and ailerons. Additionally, sufficient exponential needs to be used to melt the response of the plane. For my 3D flight mode, I usually use round 65% of exponential.
In the most elementary type, flight modes include twin or triple charges for all management surfaces on a single change. Different mixes and different desired features may also be utilized to sure change settings, however in the curiosity of this column, a number of charges are obligatory for consistency upon entry and exit for the determine. When you enter the spin, for instance, you need to be in your 3D flight mode to make sure a particularly flat spin rotation. Push the mannequin right into a vertical downline the place you start rolling and carry out the blender. A fee change just isn’t required for this determine, however as soon as the plane completes the maneuver, the pilot ought to return to the low-rate setting to handle the place of the plane. Once the airspeed will increase, return the fee to a lowered setting.
OVERVIEW
For your first few makes an attempt, altitude is essential. Enter the maneuver into the wind and parallel to the runway. During the rolling section, altitude will rapidly be misplaced, so begin at about 700 ft. Decrease throttle and regularly feed in up-elevator to take care of altitude whereas utilizing the 3D flight mode. As the plane comes to a whole cease and stalls (ideally instantly in entrance of you), it’ll drop a wing. Continue holding up-elevator and apply the required management instructions in the path of the stalled wing, which embrace aileron and rudder in the identical path coupled with most up-elevator. Only a contact of aileron is required throughout the rotation for a particularly flat rotation. If the plane doesn’t stall and begins to descend whereas at a nose-high angle, merely add a contact of aileron and full rudder in the most popular path.
After just a few rotations, launch all management inputs however proceed holding aileron in the identical path as the rotation. After a roll or two, proceed holding aileron enter however apply full down-elevator and reverse rudder to execute the inverted flat-spin portion of the blender. To exit, neutralize inputs and set up a vertical downline. Push elevator to an inverted exit. With apply, you can too add some aptitude by exiting the determine with an inverted harrier.
BY THE NUMBERS
REMEMBER, SOME MODELS MIGHT PERFORM A RELATIVELY FLAT SPIN, BOTH DURING THE UPRIGHT SEGMENT AS WELL AS THE INVERTED PORTION DURING THE BLENDER, WHEREAS OTHERS MIGHT NOT.
Step 1: Fly the airplane parallel to the runway and at a really excessive altitude. When prepared, change to 3D flight mode and start to regularly lower throttle; as the airspeed begins to decelerate, apply the required quantity of up-elevator to take care of altitude. For this determine, the objective is to have the mannequin come to a cease and stall instantly in entrance of the pilot. At that time, a wingtip will stall and the plane will favor a sure path, as talked about earlier. In the case of the illustration, the left wing dropped, producing a left-hand flat spin rotation.
Step 2: At the time of the stall, the pilot ought to apply full left rudder, a contact of left aileron, and full up-elevator. If an excessive amount of aileron is utilized, the plane is not going to carry out a flat rotation and can, as a substitute, carry out what seems to be an inside tumble. Once a rotation or two has been accomplished, relying in your altitude, begin to enter right into a rolling vertical downline at a reasonably gradual roll fee.
Step 3: To start the inverted spin, apply full left aileron adopted by full proper rudder and full down-elevator. Decrease the aileron enter, as wanted, to take care of a flat rotation. Depending in your plane, you may experiment with totally different throttle settings to additional flatten the inverted spin rotation. This produces a variety of stress, nonetheless, and so requires a structurally sound mannequin.
Step 4: To full the determine, launch management inputs and set up a vertical downline. Let the plane acquire some airspeed, change to your low-rate flight mode, and push 90 levels to an inverted exit. Continue to make use of sufficient down-elevator to take care of straight and degree inverted flight.
ENTER the maneuver into the wind in straight and degree flight.
1 Gradually cut back energy whereas growing up-elevator to take care of straight and degree flight.
2 As the airplane stalls and the nostril begins to drop, one among the wing ideas may even drop. This dictates the path of the flat spin. To set up the flat upright spin, apply full left rudder, a contact of left aileron, and full up-elevator.
3 After establishing a vertical, gradual, rolling downline, start the inverted spin by making use of full left aileron adopted by full proper rudder and full down-elevator. Decrease aileron enter accordingly to flatten the rotation.
4 To finish the flat spin, launch all management inputs and set up a vertical downline. Let the airplane acquire some airspeed and push down-elevator to enter inverted flight.
EXIT the maneuver in inverted straight and degree flight in the other way of the entry heading.
FINAL THOUGHTS
Remember, some fashions would possibly carry out a comparatively flat spin, each throughout the upright section in addition to the inverted portion throughout the blender, whereas others may not. If you could have hassle mastering this maneuver, don’t develop into discouraged. It is vital to research your state of affairs and examine the CG (it could require including a contact of tail weight). Also, your airplane may not have giant sufficient management surfaces or sufficient control-surface deflection, so experiment along with your setup till you discover the correct mixture.
