Hey Grifflyer,
I am 95% finished. But now I have doubts. I got a 50mm EDF motor that the website says give 480W continuous power. It can give 800g of thrust. I tested it now in the L39 with thrust tube. I get 385W of power and when I put the L39 upside down on a scale that has been zeroed I only get 398g of trust. But I do not know if this is the correct way of testing an EDF setup. I have never had or flown an EDF Jet.
Like I said in other post, we in South Africa do not get the same foam board than the guys from Flite Test. So, you said your plane is 340g dry weight and 482g all up. Mine is 520g with servos, ESC, EDF and RX. No Battery !!
So, can you guys with the experience say if I am under powered please.
Pic's below is 95% done plane, need to neaten up where i glued the top peace and H&V
