on my Funtana 40, (not sure if you have 40 or 90, I think you're referring to the 40), I just tail mounted everything, using that engine you should not need nose weight....

Having trouble with mine at the reccommended CG, pull up hard, it banks right, someone on here suggested I move the CG back, which i did but have not gotten the chance to test fly it yet, my elevators are hinged with the supplied metal rod which they give you in the kit, if i remember correctly.
