Dear Bill/Amram:

Thanks for your reply, it is very useful. I do not use T/C, I will test in the future but I like to adjust my model before add more complexity!!
Your TS Oxalys have a good fit between wing and fuselaje/cowl? The wing seat on mine is not Ok with gap in the front. I plain to add some wood in the front of fuselaje, its mind add negative incidence in wing, I will need to modifie stab incidence and at the end I will have positive incidence in the engine, I am talking for about 1/3 degree only but I am sure it can help. I will test again later to know if it is need more adjust.

Best Regards.
