I been flying the kaiser Mk I and Mk II for many many years.  Built my first Kaiser long time ago .. i.e. sometime in the mid 1980's.  Well being friends with Sharma's is a great thing as they helped me a lot in my hobby..  Lately been flying both the types i.e. with a high wing and one with a low wing.... maybe visit my thread for the sweepstakes of 2015.... I have bult my latest ones out of thermocol and have enjoyed flying them.  They weigh about 1.2-1.4 kgs.

Well Kamalsahai... the entire world revolves around the CG..... nothing works without the CG being at the right place.  You too would topple if your CH went out of the correct place.....
