Hi All;

I am in the process of building a HOB 2 X 4 sailplane that I would like to modify to nitro power. Below are the spec of the 2 X 4. I was thinking of trying an OS .15 engine. Servos will be HiTec 55 with three channel operation. I am not looking for speed or anything like that, just looking to have a nice slow gentle Sunday afternoon flyer. This would be a tail dragger with a light landing gear using 2.25 on the main nerf tires. Would the OS .15 do the the job for me? Any help that anyone can give me I will put to good use. Thanks alot.

SPECS:
Wingspan: 49.5"
Wing Area: 409 sq in
Wing Loading: 9.8 oz/sq ft
Weight With Standard Radio: 28 ounces
Fuselage Length: 38.5"
Airfoil: Flat-Bottom, Polyhedral

.15 is way too big for this glider. I flew a 500 sq.inch wing glider with an OS.10 and that was big enough. And don't bother with landing gear on a glider- just give it a hand toss to launch.

even a cox .049 have been used in poerpods for sailplanes.

you can still get cox 049 TDs if you look around . there are other fun options as well and most will have throttle. i really recomend the power pod route as it fits under the wing rubber bands and doesn't change CG. this way you can still use it for non motored fun.

try glow sticks or LED lights at night[sm=what_smile.gif] we stick the glowsticks on with clear tape out on the wing tips so they are visable from top and bottom. one for the tail as well. you need at least three to be able to tell if the bird is level in flight. the red and blue glow stick are not to bright, we like the old fasion color as it shows up better.

i just finished and recently maidened a 99" butterfly power glider with to sets of lights glow wire and LED separate systems.
this plane is a classic its been around for decades. it is SOOOO slow i thought it would fall out of the air on its first launch it was that slow! mine has a 25 magnum on the nose. it is slow but will climb like a home sick angel into the wind under power.

I hollered "DEAD STICK " the first time it ran out of gas the guys just gave me "the bird".... well I was around 300 plus feet up!
