Mentioning props on RCU is opening a can of worms but on my OS 120 in my extra it tested best with the APC 15X8 but mine is a lot heavier plane then the GP Extra. Testing different brands and sizes is really the only way to find the prop you like the best.
Looks like your best bet is to just stick on the lead and forget about it. On your next build you may want to log onto RCU and find an old build thread to see what others have done to there planes and what problems they encountered like the CG. There are a lot of threads on the GP Extra.
Yea, I didn't think it through when I was building it. I knew it would be nose heavy but not this bad. I could always put the recommended engine in it and fly before I do any serious mods.
I've flown a long time and never had this type of nose cone break, I do thorough inspections in between flights though I did have an aileron come loose during one flight. That was loads of fun and I managed to land it.
Thanks for the input.
