Adding afterburner to a plane?

[circassian 1]

Hi guys,

I have the "rkt_f35" addon and I want to add an afterburner to it.. I've tried to take from others like "rktf16" from config.cpp and tried to add almost everything related such files and .ppa... to the F35... but non works..

Anyone can help?
