Super Simple Blunt Nose Flying Wing (TikoWing V4)

This design is my 4th of my flying wing series, and the 3rd of my successful design (my V2 seems not working good, so I think that's a fail one)

In this design, my 4th design, I try to choose thicker airfoil to get enough space for battery hatch and also to increase the lift, unfortunately, the drag also increased accordingly. However, this design has more stable for slow fly, even in very windy conditions. Here is the footage of my maiden in the windy condition (gulf wind characteristic, with 15 km/hour or about 10 miles/hour average speed with at least 70% probability of turbulence) and it flies wonderfully. Here is the footage of my maiden flight.

I take "Super Simple" on the title because this design only requires small number of cut, and all the cut is just straight cut (no curve cut) makes this design easy to build even by the one who just start this hobby. here is the preview of the plan.

if you interested to build this, here is the actual size of the plan TikoWing V4 (you can scale it to 30" X 20") foamboard if you wish

Here is the timelapse that I record when I build the plan

Specification:

• wingspan                : 36" (or 30" if you scale it for 30" foamboard)
• AUW                      : 550g
• flight time                : 15 minutes (full charge to light discharge)
• stall speed              : about 15km/hour (about 10 Mile/hour)
• flight characteristic   : slow - medium speed, unlimited vertical climb, steady flight

component:

• battery          : 2200mAh 3s 20-30C
• esc               : brushless 30A
• motor            : 2000-2300kv (max current at least 20A)
• prop              : APC E 6x4
• radio system : at least 3 hanel with elevon mixing capabilities
• servo             : 9 gram servo
• material         : one sheet of foamboard

I hope you enjoy it.
