Kwik-Fli, Slow Build: 29 June 2011

Kwik-Fli, Slow Build Blog Series header graphic. With a close-up of the model's engine at center, the graphic is done in orange and blue.

In the past few days I had been adding the cap-strips and now the wing is finished (the ailerons are still to be cut, but all the major components are in place). I took it on the port and gave it a good sanding job. I can’t say I’m finished, but I’m 80% complete, I would say… Probably I’ll apply some glue and will sand the wing again, before cutting the ailerons. Eventually, I weighed the wing and it turned out gr. 685, Aileron Servo included.
This is the Mk. III Weight Chart:

Scan of the Kwik-Fli III weight chart.  Here's the information: Wing (+servo)	Gr. 750 Fuse	Gr. 620 Servos (3)	Gr. 153 Landing Gear	Gr. 120 Wheels	Gr. 120 Fuel Tank	Gr. 69 Engine + Muffler	Gr. 570 Engine Mount + Prop	Gr. 22 Battery, Switch, Rx	Gr. 136 Total	Gr. 2,560
And this is the Mk. II:

Scan of the Kwik Fli Mk. II weight chart. Here's the info: Wing (+servo)	Gr. 685 Fuse	Gr. 420 Servos (3)	Gr. 153 Landing Gear	Gr. 120 Wheels	Gr. 120 Fuel Tank	Gr. 69 Engine + Muffler	Gr. 527 Engine Mount + Prop	Gr. 22 Battery, Switch, Rx	Gr. 136 Total	Gr. 2,252
This wing is only 65 grams lighter (10%), but I think it looks nicer… Besides, this also comes from a Kit and the balsa could have been much lighter…
Now, once the table will be complete, I can apply the same reasoning to the Mk. II as well and see how the projected final weight looks like.
The Mk. II should come out 300 grams (or 10 oz, at least) lighter than the Mk. III, therefore around 93 ounces, or 5.8lb. Good! The ENYA 60 III will be very happy!

Coming up: Beppe takes a building break, but we keep posting.  Next post: July 15, 2019
