Thank you Skydiverdriver,

After the water (corn starch) is released I just let she goes "up",, the tank is installed really on the cg spot, she just flies lighter after the release and jumps in speed.
But it is really fun !

Hi Andy,

I have just read your post and I´m smiling. I´m happy your first build has turned out so well. Quick and responsive seems a very good combination to me .

Now you know why I like these planes. Well done!

Robert and Nelson

Many thanks for your kind words and for all the help you gave me, before, and throughout this build.

Hi SumthinsFishy,

I just post a video in my Blog that will show some details about the mechanism.
Any doubts let me know ok?

Hi guys,

Not to much progress on the Rufe. Some progress nevertheless. I made two pods for under the wing to attach the tipfloats to. I took some 1 mm plywood and made a sandwich construction. three layers of plywood and the middle piece has a gap of about 4 mm to fit the carbon strud in of the tipfloat. Tipfloats have been fully shapes and look rather well. A flat piece of caron functions as tipfloat strud. It has been glued in with epoxy. To finish the pods, the prementioned plywood construction had been glued between two pieces of balsa. The whole pod has been shaped like a dome using a dremeltool, a knife and some sandpaper.

The center pylon has been corrected for a twist it contained so the mainfloat will track straight with the fuselage of the plane when the wing is mounted in the wingsaddle.

The firewall has been glued into the left halve of the fuse.

Finally I started to shape the covering for the center pylon. I might redo it because the current pieces of foam are curved at the inside and the give me some issues.

Pictures wont show much difference as before so I'll spare you those.

I need to start work on the controls. Still thinking about how to do a rudder on the main float. I know it can make all the difference for water handling...

Robert

Hi guys,

Did some extra work on the Rufe. I shaped the centerpylon a bit and trialfitted the tipfloats with double sided tape. Also put in an aileron servo but you can't see in the pictures. Water rudder will not do much good if the plane floats this high in the water...

Robert

Robert,

You are gonna need a bigger motor to takeoff out of that little pond!

Nice work, as usual.

As per the recommendations on this thread, I bought this speed controller for one of these Gravity Hobby planes:

TURNIGY Plush 6A /.8bec/6g Speed Controller
http://www.hobbyking.com/hobbyking/s...idProduct=4318

I also bought this battery to go with it:

Rhino 360mAh 2S 7.4v 20C Lipoly Pack
http://www.hobbyking.com/hobbyking/s...idProduct=7301

Now that the items have arrived, I see that I need a female connector for the ESC to the battery.

What kind of connector do I need and can I order one through Hobby King?

Thanks,
Frog

Hi Frog

You need a JST female connector. http://hobbyking.com/hobbyking/store...idProduct=9631

HK are on backorder, but they'er cheap on Ebay too.
Regards
Andy

PS Good choice on the ESC and battery.

You need these if you wanna use the connector the battery comes with. A lot of people change them to Deans or other style connectors, because they already have them. But, for this size kit, I like this size as they are small and light weight.

Go to your LHS if you want to buy just one. Otherwise, HK has been out for a while. I picked up these from eBay. They are 10 sets of both male and female.

Hey Frog

Welcome to the Cox thread, I'm new to these planes too. I've just about finished my first plane, I've had a whole lot of fun doing it. BTW what part of the world do you live and what's your name.
Andy

Hey giuseppi,

I took your advice, and made a heavier spinner from the original. I filled it with blue tak. I took out 4.5g from the cowling, and only had to add 2.5g into the spinner to get the CG spot on. I just want to say thanks for the tip.
All the best
Andy

Hi Frog,

I see you have bought the brushless esc but did you also buy a brushless motor with that? The supplied motor is a brushed motor and it needs an esc which is specially made for brushed motors. The difference can be seen from the amount of wires coming out for the motor. The brushed motor needs two, the brushless needs three.

This one is being used quite often. It might be a good idea to buy one.

Robert

Glad it worked out for you andy. Just to be clear. What I was actually suggesting was to add a flat washer or two between the aluminum spinner and the prop.
