Well, it seems I have made most of the mistakes in this sport and tried to do the others....and this is one.
Even though I did it on a single engine plane ( Please do not tell the guys in the twins forum) it was an ugly stick, it did work.
I admit that hovering has always not been my strong point,,,,,,,,so...why not get the CG to move back......A LOT.
All that practice stuff just burns fuel!!!
How to do, if you have a few loose screws and a plane you are willing to try this on.
Get a 1/4" thick x 1.5" wide x 18" or whatever length you need, long piece of plywood. Make a "Sled" frame to wrap around the long plywood and attach a four ounce ( or whatever) lead bar to it.The idea is to allow this "Sled" to slide up and down the plywood.
Put a pulley on one end and a "Sail Wench" servo on the other. These are the servos used to control the wind sails on RC sail boats.
They are completely controlable in their 3 revolutions according to transmitter input.
Rig up the fishing line to the sled, around the pulley on one end, and the winch servo on the other end.
Set the end points on the transmitter for this channel to not over move the "Sled". Suggest put the operation on a switch, verses a rotary knob.
For take off, set the Sled to normal CG,,,,,,,,but for hovering. ..HIT THE SWITCH...and watch the tail fall like a rock........uh ...did I mention to try this away from the flight line and four mistakes high......and that you have enough power to hover and pull out? DO!!
Remeber that it takes 1-3 seconds for the weight to move front to rear, so do not expect to get out of trouble instantly.
Does it work.....you bet and is good hovering practice.
Crazy to try......You bet,,,,,,,but what do I know,,,,I fly twins.
Have fun.
