Sanjay sir,
The cub is taking shape beautifully. Now I and Arvind will have to strike a deal as to who gets to maiden this.

Hello Sir, Build is coming out good. I see special focus to strengthening to the Wing, Specially the innovative idea of angle adjustable Wing struts.

Wing Struts construction. I am using a 9 mm OD Aluminium tube

With lots of work, and WC T20 cricket, didn't get much time last week. Anyway, did something today

sanjayrai55 · April 03, 2016, 07:48:22 PM

First step was fitting the wings in place. So put the battery etc., figured out the CoG, and fitted wing bolt mounts. The model is slightly tail heavy now; have to do some further work on the front end, then will see if I need to add any nose weight

sanjayrai55 · April 03, 2016, 07:52:30 PM

The wing mount supports are made of 12 mm balsa sandwiched between 2 mm ply sheets. Used 6 mm blind nuts

Used self tapping screws first for location, and later as functional. Epoxied in the mount supports. Ran a drop of cyano into the balsa, else the threads get worn too fast

Just did a quick check on Incidence Angle.

zabardast, when is the maiden?

sanjayrai55 · April 04, 2016, 02:06:09 PM

Thanks Satz

Thanks Saurabh. No angle is mentioned, but in the drawing there seems to be a very small angle, like LE about 8 mm higher than TE w.r.t. Stab. I'll put pics soon of the struts

Thanks Girish. I think another 2 Sundays and it will be ready. Maiden after that, but need a place to fly it: can't fly it in the usual park at Sector 29

manojswizera · April 10, 2016, 09:10:30 AM

WOW.. beauty sir.
The wing struts are old tv antenna ??

Cub is one of my favorite model, thinking of building one from long time.
Your build is inspiring me to build soon.

sanjayrai55 · April 10, 2016, 10:05:50 AM

Thanks Manoj

Not really TV antennae, but similar. Simple 8/9 mm Aluminium tube from a hardware store.

Go ahead and make one Manoj - there are countless plans for cubs in various sizes, power sources and materials on the net.
