Attached are some pics of my latest A/B classic ship! It's the Big Dawg Electric kit by Top Knotch Products but I've shortened the nose in order to get the CG correct due to the difference in the weight of the pwr. systems. Wing area is 560 sq. in. with an aspect ratio 7.65. Wing and stab construction is full geodetic with sheer webs. Fus. is full box, very strong and stiff, pwr. is a new K&B 3.5 with an APC 7.8 x 4 prop. As soon as the winds and storms clear out hear in middle Tennessee we'll see how she'll fly.

Looks good Scott.
That K&B will provide plenty of power - what fuel will you run in that?

John/Adam, thanks for the positive comments. This plane is similar to one I've been flying with an ST .23 very succesfully. John, fuel is 35% nitro 12% castor/10% synthetic. This is what I use in all my modern engines. I use 25% nitro w/25% castor oil on all my nostalgia engines.

Here are the bones of mine.  Slated to receive a Novarossi .21 hence the short nose.  I have provision for cutting it even shorter if needed to balance correctly.  I was extremely impressed with the degree of prefabrication of the kit, and how well the wood was selected for intended use.  You almost don't need full-size plans as the parts locate themselves with extensive tabs and slots.  Hope the pictures come through.  I have trouble attaching pictures on this forum.

Dean, bones look Great!!! Are you going to use auto rudder on it? Very interested in the performance of Novarossi .21 engine.

Auto surfaces are used to transport oneself to the flying field.  Not required for a properly constructed and trimmed Free Flight (Always Capitalize) model airplane.  The rudder hasn't been mounted yet.

 The Novarossi is an unknown, but highly acclaimed by Controline (Also Always Capitalize) Proto Speed Flyers.  Hope so, it weighs as much as some .40's!!!

Stay tuned. Wink
