Hi Guys, Just how critical is blade weight ? I purchased what was classed as Medium density balsa on-line, from one of the main suppliers. After I made them and covered them with Profilm each of the finished blades weighed 48g. I noted from Rich's write up they should be 50-65g. I have raised this topic as I am not having a lot of success flying it.
The model will take off fine and does not tend to roll left, or right, climbs away fine, at a reasonable air speed. However as soon as try and make a smooth turn the blades appear to cause a stall resulting in the model dropping out of the sky before I have time to react.
On the first flight the blade were set 90 deg to the mast, recommended as the starting point. The C of G was set 50mm from the mast entry point.
I used coolwinds plates and shims, so this should not be an issue. I was expecting to make some trimming adjustments. But have not managed to reach that stage.
Using 6.5kg metal gear servos, 2mm rods.
On the second fight I had increased the hang angle by few degrees, however this has not helped. Making some blade of a higher density balsa appears to be my only option.
