Bowker Aero Epp x-35

This post in my blog is to serve as a build guide for those who purchased an EPP X-35 kit from me at TINY, I plan to move this build guide over to the 3D foamie's section shortly. If you are interested in mail ordering a kit, Please email me at [email protected], Full kits are $35 + shipping and come with all the carbon spars and ply hardware seen in this build, along with heatshrink, music wire and thread for lashing. All parts are CNC cut.

The Epp X-35 is a 4 channel 3D pusher, capable of almost every 3D maneuver in the book, rolling harriers, rolling loops, hovering, flat spins, you name it. Its a blast to fly and a real crowd stopper as you do things that a pusher jet just shouldn't.

A quick look at the EPP X-35

Wingspan: 24"
Length: aprox 30"
Flying weight: 6-7oz

Recommended radio gear:
Hacker A-10-15s or A-10-9L(the model is designed to fly on a 8" prop(max), your motor selection should reflect this)
ESC:10 amp
Servo's: 6-7g(hs-55's used in this build)
Battery: 2s 360-450 mAh

I will be using Welders glue to build my X-35, To get a faster drying time I use the following technique: A bead of Welders is applied to one side of the joint, the two pieces of foam are then worked together to spread the glue across both sides of the joint, the two pieces are then pulled apart and left to get "tacky" before reconnecting them. Once they are reconnected you will have little room to adjust the part so work carefully to get proper alignment.

You will need to set up the "Delta" wing or "Elevon" mixing on your TX for the X-35, I will add a section later about how to do this on a JR or Spektrum TX.

I fly my X-35 with max deflection set around 45-50 degrees with 90% expo and low rates at aprox 75% of max travel with 60-70% expo.

If you have any comments, questions, ect, please feel free to post. These kits are back in stock now and ready to ship. Thanks for reading

I'm working on getting a video...Ive been to distracted by other outdoor projects...I do have "production kits" ready to ship, They are almost the same with one more joint in the wing to help on shipping costs and a few ever so small tweaks to help the fit of everything.
