Not the build... I suspected differential thrust.

Santhosh's electronics are always perfect, that's why i didn't question his build.

everything is as per the manual, used the suggested rimfire motors,esc's props etc.for my  mpx twinstar  i cut the centre lead of one of the esc's and conected it through  a y cable to the rx,for the catalina i didn't. connected the two esc's to a y cable and to the rx as the manual says so, not sure that make a big difference
