Old-Timers/Mathews Continued page 51 displacement youre going use Donalds case Buccaneer Standard its rather weak wing 25-cu-in engine might too much SAMs competition rule 225 sq 10 cu model climbs flies very fast general sport flying just way too much power suggestion has keep power down enjoy Old-Timers manner fly best using four-cycle power plant particu larly second-generation ones use 75% displacement calculate displacement similar-power two-cycle 40 fourcycle close power 30 two-cycle Spark-ignition engines either originals repro ductions should used basic one-to-one ratio remember technological progress has bearing situation too Lets face Brown Jr McCoy may both 60-cu-indisplacement engines alike power Another frequent problem Old-Timers wing structure too sound structurally Free Flights Add RC gear few tight turns loops much too weak pet technique overcoming substitute spruce wing spars original balsa add vertical-grain shear webbing frequently add rear double spars also particularly wing like Buccaneer Standard Fuselage structures usually strong enough designed since old spark-ignition engines vibration-prone needed beefy frames Interestingly enough modern radio equipment doesnt weigh great deal old spark-ignition coil batteries Another factor consider covering material Modem heat-shrink coverings just dont add rigidity structure silkspan bamboo paper silk Therefore wing andto lesser degreethe empennage will need help model covered heat-shrink material would remiss failed mention heat-shrinks equal either Specifically Buccaneer Standard doing would have t6 spruce spars front rear /32 vertical-grain shear webs between front spars Id also likely use x 1 trailing edge double ribs center section sheeting top bottom center second spar bvious hinge lines would about right small scraps same material added insides hinge points hinges could get full half-inch bite Otherwise empennage should fine As far fuselage changes go thing October 1 986 141 RUBBER
