Gazza58 Posted February 6, 2016 Share Posted February 6, 2016 Hello chaps. My Ballerina is nearly finished as regards the fuselage. I will be laying down the wing this afternoon in the fashion suggested by the highly esteemed designer. I have not built up a wing in this way before but will give it a go. The point of my raising a thread here is to ask about the thrust line for the engine mount. I would normally have a few degrees of down/side thrust. As this cowl is not detachable, I would like to get it right previous to mounting the nose ring. Once the nose ring and cowl is constructed it will not look good if the thrust line needs altering as the cowl and spinner will be out of line. I would be grateful for any suggestions.

Craig Thomas Posted February 6, 2016 Share Posted February 6, 2016 Hi Gary. Im sure I read somewhere that Peter dosent put any angle thrust in. I'm sure someone more experienced can explain better. But as far as I know there is none. Quote Link to comment Share on other sites More sharing options...
Chris Barlow Posted February 6, 2016 Share Posted February 6, 2016 Yes Peter has said that the plan has zero side and down thrust and I've built mine as plan, however I do prefer my models to climb on power and sit slightly nose down on the glide so that may be why. Depends what you prefer and how you fly I suppose? Quote Link to comment Share on other sites More sharing options...
Gazza58 Posted February 6, 2016 Author Share Posted February 6, 2016 OK chaps thanks for your answers. I apologize if this question has been answered but I haven't found any mention of it before. I am considering a couple of degrees/washers between the bulk head and the engine mount. I think I would prefer a neutral response to height change when I open the throttle. I am still open to the subject as I haven't mounted the motor yet. Gazza Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted February 6, 2016 Share Posted February 6, 2016 It's been discussed a few times Gazza but finding it won't be easy, opinion seems split, so I would go with what you feel best, mines getting some side/down thrust on it.

kc Posted February 6, 2016 Share Posted February 6, 2016 Peter's wing build method worked well for me on another of his designs, so I will use it again. Follow the sequence properly and don't forget to put all the proper parts down onto the board at the early stage. Quote Link to comment Share on other sites More sharing options...
Gazza58 Posted February 6, 2016 Author Share Posted February 6, 2016 Thanks John,and kc I'll stick with what I am familiar with and give it a 'bit' of down/side thrust using washers behind the engine mount for down and between the mount and the engine for side thrust.
