Default RE: Magic Hand 73" yak build thread

Here are the details on the kit and some weights.
below is a link to the kit at TBM. Sale price is $229.00 and $39.00 shipping.

I have a few pictures of the plane and the weights for the set up I will be using. The website shows this plane coming in at 10 lbs. I was hoping for 10-10.5 lbs but that may be a tad optimistic.

The plane comes double boxed in a very rigid outer box. The build quality appears exceptional. The surfaces are all double beveled, cowl has a ring for a hidden mount from inside the fuse. The glass and paint on the cowl are flawless and have great detail. It rivals any glass work I have seen on a model plane. It comes protected with tissue paper and bubble wrap. The plane comes pre-plumbed and the connections zip-tied along with a fuel dot. (smaller than needed and will be changed in future offerings per TBM, it will be changed along with the fuel line as it looks narrow). The canopy is very nice and again came double wrapped in tissue paper and bubble wrap. All covering was excellent quality. Hinges are CA type and are preinstalled in the wings. Tail surfaces are installed in the flying surfaces. The horizontal stab is one piece. My plane didn't come with instructions but they can be downloaded from the TBM site. The hardware included is average quality. I have an EF Yak NIB and the hardware is much better with the EF yak. I will probably be changing out some of the hardware for 4-40 dubro stuff.

The setup will be as follows:
OS 1.60 with Slimline Pitts muffler
Hitec 5925s on Ailerons and Elevator
Hitec 5985 on rudder
Hitec 225mg on throttle
6 vt Nicad battery

Here are the weights I have for the plane and the setup: I used a digital postal scale for the below weights.

Right Wing 15.7 oz
Left Wing 15.7 oz
Hor Stab 6.5 oz
Rudder 3.5 oz
