I HAVE A DIRECT CONNECTION 10-300 ULTIMATE BIPE. THE WING SPAN IS 62 IN. DOES ANYONE KNOW WHERE THE C/G WOULD BE FOR THIS PLANE. ALSO THERE WEB SITE [ DIRECT CONNECTION ] SAYS THIS PLANE WILL FLY WITH A 91 2/S TO A 120 F/S. HAS ANYONE INSTALLED A LARGER ENGINE AND IF SO WHAT SIZE. I AM CONSIDERING A MOKI 135 AND WAS WONDERING IF THIS IS TOO MUCH FOR THIS PLANE. THANK YOU.
