OK more progress! I used some hot melt glue for the fan unit. The fan I used is a little shorter so I used the back end of a marker and pushed the foam to remove the small lip. I did the same on the EDF hatch as well. The wing panels were epoxied on with 5 minute epoxy. They do give lots of gluing surface which is nice.
Since I am flying with no retracts I only need a Berg 4 receiver and I installed it in the nose gear wheel well and placed some foam to hold it in place. I plan on putting a foam piece in the wheel well to block it off. Don |

All finished!!!!
The model balances perfectly with a Flightmax 4S2650 20C lipo. AUW is 32 ounces. I get just over 1:1 thrust to weight ratio. Don |

Hey don, looks good! How about a profile shot? I want to see if it has the correct look from the side before I order one.

I did some quick calculations: fan sweep area: 4.87 sq inches inlet area: 8.31 sq inches exit area: 5.24 sq inches so inlet is 170% FSA and the exit is 107% Don |

Starts about 700 and settles to about 650 watts. Should fly reasonably well.
