Floater jet replecement prop

Message Topic Search Topic Options Post Reply Create New Topic Printable Version

Because this is a pusher setup, is there a special prop I need? I realise you could reverse motor direction, but isn't there a possible problem with losing the prop by spinning loose?

Also there is a youtube vid http://www.youtube.com/watch?feature=endscreen&NR=1&v=Txawn37qwHA showing using a 6x5 prop instead of 5x5. It claims better climbing but slower top speed. That does not make sense to me, because AFAICS, using a bigger prop with the same pitch, if anything will give equal better top speed and possibly _worse_ climbing if it makes the motor labour and slow down.

Any help etc.
