RE: Quique Somenzini YAK-54S 73"
Well maybe this is some new news?
The 73" will build out at approximately the same weight, and while it has a 1" longer wingspan, it also features a deeper chord, resulting in 17% more wingarea. The tail area has also changed. This change was made to enhance the 3D ability while still maintaining the precision found in the 72".
Quique said he believes a lot of people will be pleasantly surprised with it's uncanny stability in high alpha flight. He says it waterfalls like he has never seen. Yet snap rolls and tracks with precision.
Other changes were made in response to customer input... The hingepoints have been replaced with metal pinned flat hinges (aka Klett style) and the plastic clevises have been replaced with top quality ball links. 2/56 rods are gone and the plane will ship with 4/40 titanium pushrods.
Also changed is a new rudder servo arm and stronger composite gear.
He also stated that with the increased wingarea, the plane will easily accept the smaller gas engines... to include the Evolution 26, 3W28 and RCS 1.80... others that come to mind might be the Roto 25 and if they prove to be reliable... the new CCRCPro GF26I-SP
