Default New Plan -- Loon-E Lander

Design uses Semroc BTH-70 SLS grade heavy walled tubing and shares the SLS ARCAS nose cone with 1/8" thick sturdy basswood fins. My original design also shared the SLS ARCAS tail cone but I wasn't truly happy with the CG/CP when loaded with a 24mm adapter and engine inside the originally planned 29mm engine tube or with 29mm engines so the tail cone is custom.

Flight simulation with Estes E9 engines to almost 1,300 feet, D12 engines to about 800 feet.

Posted simulations assumed a 1/8" x 36" launch rod.

Length: 23.9"
Diameter: 2.25" (BTH-70)
Span Dia: 6.80"
Weight: 4.13 oz

D12-5......807'.........Dv 8 FPS
E9-6......1,295'........Dv 15 FPS
