I agree 100%.. the EF Yak is perhaps too light to fly IMAC in much wind...
But with the same wing area... a fella could add, lets see... 3.5 lbs of weight to the EF Yak and it will fly as "stable" as a 19 lb Yak...
That's bacially strapping another DA50 to the wingtube.... tee hee... that a funny thought. Finally you can have redundant engines!
I really don't think this Yak will come in at 19lbs UNLESS you use an 80cc engine...
16.5 witha DA50... 17 max...
But again.. time will tell... what we need to know is the weight out of box that goes in the air (fuse, wings, gear. cowl, pushrods, etc)... whatever it is... add 6.5 lbs and that will be the all up weight (dry) of my Lanier Yak... within 2-3 oz...
I’m there with you. I am planning on weighting all components first. By weighting each component we can asses were to shave weight, taking in consideration CG location, cost of new parts, and difficulty of performing changes.
