These are probably better suited to 3S use:

I haven't decided yet on whether I should build them in or not since they seem so small.
Actually I added flaps. I thing SW does not need flaps because it is already a slow flyer but with flaps you can easily catch your plane when it's landing. Very effective on landings and take offs.

That was a very scenic and beautiful video, not somber at all... it depends on the mood you are I guess. I found it relaxing
You are brave flying on the water like that.

I also have flaps and I think they are really useful. Mine are set at ~45 degrees and ~85 degrees so they kill speed very effective

In my video where follow a car you clearly see where I applied flaps
(where the plane almost stops)

In my particular case, having a SW at 3.4kgs, I definitely need the flaps for launch and ......

Wow,Adam,why is it so heavy?

Hey Adam, thats a really nice video, the afternoon light always makes for a nice FPV vid IMO. I dont download and keep many FPV vids but this one is excellent. I'd like to use it to show friends what FPV looks like, so thanks for posting it..

I am also wondering what you have in there that makes you so heavy, I didnt see an answer. No doubt the extra mass works as a stabilizer making your footage so smooth.
(Found out the hard way, but we now know that the SW foam can float over 3kg )
Cheers,
R,

Originally I was a little worried about having it on the nose where it could get damaged, but its in its protective case and probably 4-5 inches up from the ground on landing, and I haven't had any problems/damage yet...except for crashing into the lake but that's a whole other story
I am so digging the cocktail hour in the background. But IMHO you need better Gin...

Good, light-weight choice motor.
Are you going to run 3S or 4S?
On 3S my guess would be, that you'd have to run a 10" or 11" prop on a motor with the 1020 kV to get the max thrust that this motor can produce safely.
On 4S probably not more than a 9x4.5E. Make sure not to over-amp this motor on 4S. If it pulls to many Amps on a 9" prop you may have to go down to 8".

I'm running two 3600 4S mains and 1250 3S for video and then I don't trust the wings so I added two wooden wing length spars on either side of the main and also epoxy reinforced the tail, then its full FPV/OSD additionally with an FY20A, GoPro-in protective case, Castle BEC Pro (hefty), E-Flite 60amp ESC (hefty), and Scorpion 3020-14 (hefty)...so all that and epoxy/Gorilla Glue and fiber tape to support it all and you get a little hefty. But it hand launches fine, flies fantastic, handles more like a stable full-scale rather than a floaty parkflyer

henk,

I'm running a 9x6 on 3s to start. I have a 5000mah batt already... I'm not running heavy to start besides the battery. Have eagle tree components inside and a 900mhz transmitter on the boom. Once I get comfortable with the plane and maybe add a gopro i would step up.

Unless somone sees somthing wrong with this combo...

RCMonster, thanks...I wasn't too brave the next day when it crashed into the lake It's a good thing it's built like a tank because the 400ft plunge didn't damage anything LOL

It took me a moment to figure that one out LOL That's why my SW is so heavy, I like to keep a bottle booze in it for emergency
