I agree with Mustang Fever. The cg as per manual is correct - and the range is small, keep it on the nose heavy side of the range in the beginning.


For newcomers to flying a WONDER:

Another point to consider is to have bright, contrasting colour scheme for top and bottom, especially when fitting bigger engines for faster flying.
See attached videoclip of how I handlaunch my brightly coloured WONDER (only 0.25 standard OS engine) - how fast it disapears into a dark dot (flies straight out and then a climb to the left - see if you can spot the dot ) - and that is with bright yellow/red stripes on top and white underneath.
This way I can see the bright flash in a turn. ..... That was why I put "OHSHEET" in big yellow letters on a red wingthe top on an earlier WONDER........see earlier pic & rest of video in an earlier posting.
Also note the trajectory of the launch - and that is where the slight up elevator comes in that Mustang is talking about.

Happy flying
