HI, Would someone be willing to help verify a reasonable engine location for my KR2s for a Jabiru 2200. Data is as follows: Ref line - firewallFuselage levelTanks empty Nothing mounted forward of firewallFirewall aft - all in place (seats, wings, canopy, turtle deck, landing gear [conventional gear], tailTwo people in seats weighing 366 lbs Look at rearward cg @ 15" behind leading edge. Understand allowable range is 8" to 16". Firewall to wing leading edge is 14.5" Weight on mains is 615# 17.625" behind ref lineWeight on tailwheel is 138# 158.25" behind ref line Estimated weight of engine, cowl, prop, mount, battery, etc. is 173# Total estimated weight is 173+615+138 = 926# Solve for D, the distance to the cg of engine, etc. 615x17,625 + 138x158.25 - 173D = 929x(14.5+15)10839.375 + 21838.5 - 27405.5 = 173D D = 30.48" Firewall to engine attach points will be 23". The tank behind the firewall holds 10 gallons. The 8" dia al wink tanks (formed to a d shape) are mounted directly behind front spar.
Appreciate help and any suggestions. Dan
