Ikarus Piccolo - Direct Drive Tail Rotor Modification

I have been toying around with a mount option for the DD setup and have come up with a very inexpensive solution. Two pieces of styrene tube from a local hobby shop.  One great feature that I didn't plan on is that the mount does not need to be glued on to the tail boom.  It fits snugly without the use of CA, so it can be removed in the event that you need to replace your tail boom.

The larger tube is 1/2" O.D. and has an I.D. just slightly smaller than the Pro/GWS motor O.D. By cutting the tube longitudinally, the expansion of the tube allows the motor to fit snugly without the use of straps, screws or glue.

The smaller 1/4" O.D. tube is trimmed to accommodate the larger 1/2" tube and is cemented together with plastic cement. To further reinforce the joint, I have added a fillet of medium CA and sprayed with accelerator for further strength. 

The tubing I purchased was white and I have painted it black. The weight (with paint) is approximately 1g.  I am using a GWS 3.0 x 2.0 propeller which has been painted black.
