I am slowly gaining momentum towards entering rc jets with a ducted fan model. Both the clubs in my area have grass fields and that is all I'll have the option to fly off. I understand that Pusher fans generate more thrust and may be more suitable for grass fields. Insofar as many more models available today seem to be geared towards tractor fans, are there advantages / disadvantages to the ramtec or dynamax fans? My prime interest is not top speeds (I know, sacraligeous to jet pilots) but again, I am a beginner. Also as a secondary question, Flying off grass should I just stick to a pusher fan? Regardless of what type I wind up using I'd be interested in the differenced in the fans. I currently have a new in box Rossi .61. Is this enough motor for an entry level jet, or should I sell it on ebay and work at getting a .90 size engine?

thanks ahead of time.
