What are the main differences between the V60 and the Four-Star 60?
There are several. 1) Sig added considerable wing structure to the FS60 kit. No doubt the wing is stronger and stiffer, but I personally think it’s unnecessary and results in a model that’s nearly a pound heavier than the typical V60. 2) The FS tends to pitch towards the belly when rudder is applied. The V60 features vital changes to the tail group that result in arrow-straight knife-edge flight. 3) The FS is famous for bouncy landings due to the main wheels being positioned too far forward. The V60’s thicker, swept-back aluminum main gear takes care of that. 4) The parts in BTE kits are machine-cut, so they have smooth, sanded edges that aren’t die-crunched or laser burnt. And every piece of wood in a BTE kit is sorted and inspected for correct density and grain.
