Opjose,

nice day of flying today. Had two flights didnt take the third to be a bit conservative because wind was picking up. Before the first flight, the club expert I was talking about tightened my cylinder head and the screws turned about quarter turn. I hadnt done this last bit of tightening because I was worried it would strip. Anyway, he did it and replaced the glow and put in a 12x8 I had and it remained operational throughout the flights till I cut it, so engine is OK.

Now that that the engine is sorted, I want to know of the setup. I hadnt set the CG and the 12x8 was too fast for landings. I also couldnt hold the nose up in hover. Even at full throws and the nose would fall forward. So which prop should I put in -13x6 or 13x4? Remaining things -cg, larger wheels etc I will handle and will report the dead weight as well soon
