BUILDING YOUR OWN TRAINING GEAR
This is what the training gear will look like. I prefer the style that stays on the ground vs. has the helicopter raised in the air. Some prefer this but I feel that the helicopter is more apt to stress the training gear and there is a chance that it might break, hence the helicopter will fall and break. This way its closer to the ground. Yes you will get that "GROUND EFFECT" but I feel that the amount of benefit you get from being 18" off the ground isn't that great. So you might as well have the helicopter safe.
NOTE: Colors depicted here are only for visibility and not what you hopefully will end up with. "Wiffle" balls are usually white with lots of holes in them. They are hollow so they are light.
These are the few parts you will need for the training gear. I have the basics for a 60 size set. If you plan on flying a smaller helicopter then you will need to shorten the dowels up some and maybe use just a smaller diameter of dowel.
4- each 3/8" or 5/16" dowels about 28" long
1- block of wood, about 3"to 4" diameter, for the center support. After drilling this you will if you want "round" off the edges. Plywood works but hardwood would hold up better.
8- each washers to fit over the size of dowels you have used
8- each "cotter" style pins
4- each large size plastic "wiffle" style balls. can be purchase from sporting good stores
4- wood screws to screw into the block of wood to "pin" the dowels into the block. Use just long enough screws to go completely through the wood, especially if you use plywood. This will help hold the wood together also.
1- Drill with small size bit
1- set of pliers
This is what the center will look like. You can if you want "round" off the edges of the center block. This will help keep it from "snagging" any thing on the ground. Drill the blocks into the dowels and use the screws to hold them in place.
At the ball ends you will put a small "cotter" style pin, a washer, the "wiffle" ball...( you might need to open up the holes so the ball will freely spin on the dowel, another washer and one last "cotter" pin. You want the "wiffle" ball to spin so you can roll around on the ground.
Another view of how the "wiffle" ball is attached. "Cotter" style pins look a little different then just a pin like I have shown. They usually look like an "R" or an upside down "U". Then is clipped with the long side in the hole or you can put both sides through and bend the ends outward to hold it in place
After you have built the training gear you will want to attach it to the heli in a "X" direction. Use rubber bands or "Tie wraps" to secure it to the helicopter. MAKE SURE THAT THE CENTER OF THE HUB OF THE TRAINING GEAR IS IN LINE WITH THE MAIN SHAFT SO YOU DON'T MOVE THE HELICOPTERS CG ANY!
Have fun! Be safe! and go learn to hover!!!!
