Tubby Returns... again
I decided to leave my last Tubby in South Africa when we left in February so I would have something to fly when we go visit my family. My wife is in great shape so I can’t call her that, and I lost a bit of weight so I guess that goes for me too.
So, after nearly a year of Tubbylessness... I have finally gotten around to ignoring all the other projects on my to-do list and decided to build another Tubby.
I changed the wing a little (added some to the chord) because that is what I originally wanted to do but got scared of the unknown and made it with a narrower chord originally… This Tubby is also made from scraps of foam I have had lying around for quite some time now. The green wings are from part of a foam box I received an airplane in from a seller in China, the yellow horizontal stab and elevator are from leftovers of the lower wing of my old Ultrafly Outrage bipe, the grey fuse sides are from some depron scraps I found in our storage unit (I purchased the original depron sheet in 2006) and lastly the white vertical stab and rudder are from some depron-like foam (woodlak) I purchased in South Korea while my wife and I were teaching English there during 2007-2008. Scrappy might thus be a more appropriate name for this little Tubby. Oh and the pushrods are the original from the very first Tubby. I found them in my parts container.
The wheels were Trexler 3” balloon wheels, I finally decided to splurge and buy these wheels earlier this year as they were the wheels I had in mind when designing the original Tubby and I wanted to see what Tubby is really supposed to look like. Now, 2 years after the first one was built I was finally able to see the desired result! I said "were" at the start of this paragraph because after putting the cute little wheels on and taking some pictures I found that the plane was quite tail heavy. I considered adding a bigger battery but I was a little nervous taking off and landing on little balloons so I resorted back to heavy foam wheels. They don't look quite as cute and won't have the bounce of the balloon wheels but I feel a lot more at ease with them on. Plus they balance the plane just right.
After some trimming Tubby flies great! Here is the video:
Wing Span: ~24"
AUW: 151grams (5.32oz)
Wing Loading: ~4.75 oz/sqft
Motor: D1811 "10gram" 2000Kv brushless outrunner
ESC: Pentium 6A
Servos: 2x "3.7gram"
Battery: 2S 500mAh lipo
That s nice!!
I have the same power system at home. and was looking for
some thing simple to go with it. Also wanted to put it next to
my 82" Mudd Duck Nitro I built this summer
