Actually - 3/16" dia wire struts are lighter - much les expensive and far less likelily to cause any internal damage- I came up with a X shaped former , which I fit into the fuselage--then each gear leg straps into a 90 degree angled slot. (up each botom leg of the x then turns to the upper leg.).
I know - it isn't cool - but it sure works better than the CF stuff- --and did I say lighter?
