HA! This will be interesting. Are you planning to build it?
Ive thought of making the regular plans about 20% bigger and modding a FPV plane out of it(without the step, and without wing skids).
If you built the nacelle square it should be fine as it's laser cut. There should be 5 degrees of right thrust built in, which is a little bit above what you usually see.

Thanks fiend, I check square at every step in the build process (OCD about that probably) but I know very little about thrust angles and such. I'll trust the laser cut. It's been a fun build.

What did it end up weighing? Mine was around 600 grams w/o battery. C pack motor and electronics. Also, I suspect the servos and receiver are heavier because of the water proofing in them. Also, I made it using the "old school hinges" using an article on this site, and I also added dowels to give the tail more support. I'll need to push the battery very far forward in order to get the CG right. Hopefully I can get a little testing in the air this weekend. Hope it's not too heavy to fly. I did set up flaperons so perhaps slow speeds will still be possible.

Well, somehow, with everything but a battery installed, mine ended up at 702 grams. Way too heavy to fly, even with a C-pack motor and a 2200ma battery. At least I think that's what happened. The plans say 428 grams dry weight, 612 all up. What is the definition of dry weight? I assume all up includes a battery?
I think I need to learn to be much more judicious with the hot glue.
The CG was good, but the plane nose dived right after a hand launch. Ah well. It's a nice looking plane

Flew one yesterday. This will be a good winter plane
I definitely plan on building my Otter and Sea Duck kits to fly in the snow this winter.

Yes it will, I built mine rugged on the bottom for just such an emergency. LOL

More than that, apparently. Anyone see any build issues other than 702 grams?
Thanks,

700 grams is heavy, but it should still fly with the C pack motor with little issue. Tip stalls will be easier, so keep your speed up. Other than that it shouldn't be an issue.
Mike,
What is your plane covered with? Could that have added the extra weight? Other than that, looks like it should fly. What motor is that? IT does not look like the "C Pack" from FT. Looks like it could be from the "B Pack". If so, that motor is "recommended for models up to 600 grams. Could that be part of the problem? Underpowered?
