Eachine E010 ducts with struts at an angle

Just a crude some sort of thrust test with the struts in the ducts at normal and at 45 and 90 degree angle. www.rcgroups.co... In post 1112 i got the instructions how to do it. Intrigued by the findings above, with bend struts no or barely some trust gain but nevertheless getting half a minute longer flight time... So I decided a day later to try some crude prop wash tests and i too was getting peaks 4 a 5 gram more prop wash with the bend struts. The motors + props must be running more efficient with the bend struts delivering more flight time. So... XFM good find!!
