DIY Trainer Undercarriage

The Trainer undercarriage that came with my Twister V2 as good as it is for that
was just not heavy duty enough for my now larger Heli, so instead of spending more cash,
I decided to make my own, Below is step by step of its construction, some pics also just to make more sense of the description.

I used a plastic milk carton top for the central hub, across the top face of the Top
I marked out a cross as you can see in the Pic below.

The small dots ( 8 ) are for the small ties to go through and hold the carbon rods in place after,
On the serrated edge at the end of each line, either Burn or drill a 2mm or 3mm hole, Depending
on which size of carbon rod your using. Also now make the 1mm holes in the 8 positions on the top face. Also I Cut the lengths of carbon rod to 30cm.
Make the Holes near to the bottom edge of the top, so when the rods are put through and butted
together in the middle, once tied they will have just the right angle, you can see what i mean in the next two pics below.

I placed some Epoxy in the centre hub just to help keep them secure, also placed some Epoxy
at each side of the where the Rod goes through the top to help also.

For the Ends I used Golf practice balls, you can use Table Tennis balls, but the practice balls
were all i could get at the time, but they work great, as you can see in the next Pic that shows
the Undercarriage fitted to the Heli, small ties were again used just to secure the balls on
the rods and also on the Skids.

I hope this is useful to some of you out there, Oh and happy flying :)
