It has a 165" wing span, it is 116" long. We will be using a DA-150 engine with the compact mufflers (slant on front of muffler to clear the cowl). Michel used a ZDZ-160 on his prototype and is using a ZDZ-210 on his second plane. We chose the DA-150 because of it's great reputation and the fact that my partner has one on his big Bearcat and really likes it. The ZDZ-160 is about 1.4 pounds lighter than the DA-150 and the 3W 157 is a little heavier than the DA. Any of these engines would be a good choice.

I am going to work hard to get the all up weight below 55 pounds. I feel sure that I can do it.

The radio choice is the Futaba 10CAP FASST 2.4 GHZ with the R6014FS receiver. The servos are all Futaba digital as follows:
Throttle 1 ea S3152
Kill SW 1 ea S3152
Choke 1 ea S3152
Aileron 4 ea S9452
Elevator 2 ea S9351
Rudder 1 ea S9156

We are also using a Smart Fly Power Expander Sport with the receiver. Still thinking about batteries and switches.
