Bought a sky surfer from rcbazar.But when I launched, it was nose diving to right all the time. So what I did is applied a bit of hot glue to the fuselage tip so that the prop is slightly oriented to left; and that did the trick! Now it's flying perfectly.

Another perfectly flying model built, this time I glued a balsa wood piece @ front end and then drilled a hole at a downward angle using pcb drill.

doc this is a simple device used for stripping rubber down to your required
width. try and build one and use it instead of doing it by hand.

pls ask if you need more details

Yes, this is the one I was thinking of making all these days... How is it made and how to cut perfectly? Please give me details. Manually cutting to desired width is a strenuous effort. I checked the fai site, the shipping charge for a 2 dollar product is 42$ !!!! So this device would be ideal for me. Please give me the details.
