I want to take this plane with me when i travel and my quad fits in my pelican case nicely.

is there a thread (i have searched for it) that has a bunch of the mods.... many other plane threads the 1st post is just that.

Thanks for the help
Not sure if you saw this one but HK just started selling it FPVRaptor. I just ordered one I was planning on setting up for a traveling FPV setup. I also have a SkySurfer that I love but looking for a little more room for electronics. I like the PVC fus and the screw on tail. Theres a couple of utube videos on the build and flight. It also comes in a 2meter wing version. The 2meter has flaps and the smaller version has them cut in and you add the servos.

I'll use Hitec HS65MG on both tilt and pan. The pan frame will be made out of aluminum. the camera and tilt servo mount will also be made out of alumium as well or kydex.
I would do what I can to reduce the height

hi,
iīve mounted my cam at this position (my pan/tilt is like version "B"). the "cabin" costs a very large area to look forward/down.
so i would prefer version "A" ... but the load to the servogear will be too high at rough landings. you should better go for a metal gear.

cheers Thomas

Yup I did make it about 15mm lower and this is the result. This also makes it better to tilt down to look over the sides. Tilting up is not very good however I very seldom tilt up so I don't need that.

@Thint1
And, yes metal gears will be used since I'll use HS65MG.

0-25mm behind servo wire: getting better every few mm
25mm: optimum of gliding angle, speed spectrum and stability
25-35: angle getting better again, but sensible at underspeed and less selfstabilisation.
these measurements may vary at different weights an pilot skills, but 25mm will be a good start for your first flight.

my actual set is 30mm. issues at underspeed donīt matter in my case, because i use the optional flaps.

Thanks Thomas

I'm going to aim for that.

I'm worried about the stock elevator. It seems very flimsy and flexable. I'm thinking of replacing it completely with a piece of balsa. Anything wrong with my thinking?

Thanks
Hein

Even if you tighten them to the max , they will still loose grip after some flights.. and that WILL result in a hard landing remember safety when fpv'ing !!!
Get these , much much better !! http://www.hobbyking.com/hobbyking/s...idProduct=8519
You're right there - I don't trust the stock ones!! Thanks for the link. In cart..

my version came with an additional carbon-stripe for the elevator and was flexable too. i added a second stripe in the middle between original and leading edge. now itīs ok. .... accidental tested at a airspeed nearly 100km/h

a balsa elevator with this measurements will be heavier and a lot of building work - itīs like a wing for a small glider.

LOL, glad it worked out. I wish I could claim it though; I have a feeling its been done before. But Im glad I brought it to everyones attention. It definitely helps cool internals.

Wow balsa is very light, and the elevator is little more than a perfect rectangle. I'll play it safe anyway and go for the reinforcement. Thanks.

Btw took her out on maidens today, cg not perfect yet and very windy but flew fine.

Had to go back quite a bit to find this elusive mod Looks awesome!

One question, would it not create a high pressure zone messing with altimeters? I've seen many ppl actually taping shut vent holes. Just curious.

Hi guys,

does somebody finish building and flew new vers. 5 of the SW?
Link to building thread?
Some of my friends told that vers 4 was much better then 5, cause there is one only wing joiner and it is easy to fold, quality is very bad, tubes inside wings are moving freely and other bad things.
Or am I wrong?
Enybody?
Thanks.

Hi
The design looks great but the DX201 is quit a heavy camera and I feel that you might get a lot of flexing at the servo joints.
I hope I'm wrong
