RE: 40% Extra 300 Construction by-the-numbers
Landing gear.
All items carefully weighed. Landing gear is 7 oz lighter. Small 3/4 inch aluminum stock was subsituted for the 1 1/2 inch stock. The carbon gear is 1/2 inch wider at the base and 2 inches more spread. Aluminum channel and small aluminum stock alternated.
Engine box dimensions for mounting a DA 150 are as follows: 9 3/4 inch front of the firewall to the first bulkhead on the left side, and 9 3/8 inch from the left side. The engine is offset approximately 2 inches to the left and the engine holes are 5/8 inch from the top of the engine box. Attached are some pictures that may be helpful.
Started to sand the fuselage. I hope to take approximately 1.5 oz off by sanding. The 1/8 inch sheeting will hopefully be sanded down to about 3/32 to 1/16.
