Optimus F5J by CN Models
MarkTannersville, PA USA
Ordered Optimus F5J glider through Flight Comp in US. ETA is the end of January beginning of February 2017.
Plan on including build-up process here and would love to hear opinion of current owners.
CN Models is kinda new on the market but already earned a number of good reviews.
Optimus F5J is very close in characteristics with Maxa 4 and the same (or better) craftsmanship quality while costing $800+ less.
It already Won a few contests in Europe.

Cheers,

Optimus is a great airframe for a thermalling glider, long endurance UAV or an FPV platform. My goal is to build an FPV glider.
Original fuse provide very tight quarters for FPV and equipment not intended to fly straight F5J contests.
Also, I do not like the way tail looks, not just Optimus but most modern F5J gliders.
I was told it's a modern look -- call me old fashioned but I do not like sticking straight up tail fins and I drew plans for making my own tail fin for my Optimus.

Below I included a 3D design for the front of the fuse which easily houses:
1 4S 4000MAh LiPo battery - motor and FPV camera power.
2 2S 1300MAh LiPo batteries - redundant power for Jeti radio and HV servos.
Jeti w/Central Box 200 + 3 receivers.
2 mid-size servos.
1 GoPro Session or RunCam 2 camera.
1 3DR PX4 Pixhawk Autopilot.
ECU and Brushless motor.
Eagle Tree's Vector FPV with GPS module.

All of the equipment listed above fit perfectly at the same time while fuse still look sleek enough.
