Now the tail part is done. I took me a while to install the tail wheel. I substituted tail wheel brace with Great Planes stuff. I think I found why the original bracket is so soft. The whole tail block is just balsa - not much "meat" for screws to hold on. I used much wider and longer screws so they grab more material and I also soaked holes in the tail block with thin CA. It should make it a little harder.

Today I started to do "electricity". First of all the original place for switch is designed for standard RC switch. This is good for small glow engines - not for gas. I'm using heavy duty MPI switch. I didn't like the location either: just under the center of the wing. Not easy to reach. I glued in some balsa-light ply lamination just under the trailing edge and I mounted the switch on it.

I also mounted a LED-bar On-Board battery checker (set for 7.2V) to monitor the voltage of my 2 Durlite Plus LiPo flight pack. Bright LEDs are visible through the yellow covering when they are on. Battery pack with voltage regulator weights less than 4.5 oz. Not bad for 2500mAh pack that can deliver 10A constant current (20A burst) holding steady 6V.

To finish all radio setup I'm waiting for 3" HD extensions (for ailrons). But I'm really ready to put all parts together to check the sweet spot for the engine (where the plane balances the best). I'm not going to use sliding engine box - I mean not to slide it forward. I will cut the box about two inches behind the front wall and for mounting my MVVS forward I will use light aliminum stand-offs. The whole box weights 6.6oz so I'm hoping to save about 2-3oz.
