Poor hot water over the wing to warm it up, then flatten it and let it cool while still flattening the wing.

presto

Yup, flown it plenty. Just not in this configuration yet.

The ply is secured with 3 different methods. glue, screw and tape. shouldn't budge (famous last words), but as an extra precaution I'll be taping the case to the plane for each outing.

I wanted to get pure unspoilt footage, whilst still utilising a dedicated FPV cam. My dad is coming to visit on Sunday so I'm hoping to get some flying done at the weekend to "show off" the equipment.

I'll put the goggz on him and fly LOS for a bit, then I'll come in to land, put the goggz on and he can watch the flight on the archos 605 while I fly FPV

The orangeRX is right under the CG and there's plenty of room there to replace it with the arduplane board when I finally solder the headers.

Recently I crashed my B2, not so hard, only broke one of the wings. But, I was tired of the plane, my flying style is more "fast", so I decided to reuse the Bixler 2 in a different way.

Just some cuts, hot glue and tape.

Hi Corp. Have you thought of using your Gopro as the FPV cam as well as recording at the same time? My Goggles, VTX and small camera are at this moment on there way from Hobbyking China. So first stage into FPV this Christmas if it arrives in time.

Have used the gopro as fpv cam many a time, mainly on my bx1 and a few diy quads. I personally can't detect any lag, but I do have an issue with the low light performance of the GoPro. The wdr600 I use is perfect in that respect.

this was my old bx1, using GoPro as fpv cam, back when I didn't have OSD and stayed in close.

Farewell Bixler - Final FPV Flight - GoPro HD (3 min 44 sec)


I want to get some serious altitude with the bx2 so will need OSD and groundstation recorder for "proof" of my claims lol

I have HornetOSD (my personal fave) and an archos 605 that records straight from my fatshark predator goggles. no need for full on tripod GS, my equipment is capable of at least 2km and that's with perfect picture. I'll wait till I've hooked up the APM and configured RTL before I push for more distance.

Hey guys so after having read 104 I compiled all these motors amongst other notes, but I still cant figure out which would better suit my style. I am looking for a setup for long flight times doing FPV and so need something to combat winds, can be a bit fast when punched 100% throttle but most importantly one that doesn't draw too much amps/watts as I want to maintain again as long of a flight time as possible.

I might consider doing the Engine mount with the aluminum kit later on but would like to stick with using the stock engine mount for now if possible.

So the question is which motor with which prop would give effective top end speed with using as little power as possible (initial torque thrust is not as important to me but has to be able to carry fpv gear), a setup that would increase the flight time as much as possible while also having a good top speed.

Good top end speed and little power is impossible.

then it would be nice to focus on good mid range speed then (having a wot just before it starts to flutter) and maintaining a longer flight time.

some people used this motor:

http://www.hobbyking.com/hobbyking/s...00KV_696W.html

with a 6x4 e prop.

On cruise (around 40kph) at around 33% throttle, it flies for around 30 minutes... (including 2 high power launches) on a 3300 mah 3s lipo.

That is the setup i want to give a go :P

An interesting article I stumbled across, heres a link please have a read at it guys and let me know what you guys think. It does sound like lower kv/higher torque + bigger prop = more energy efficient / longer flight times? This makes me wonder about pitch as well, is the more aggressive pitch gonna mean more efficiency as well?

http://www.fpvuk.org/things-explaine...bos-explained/

Quote:
But when choosing a setup for your aircraft, remember that the larger the prop, the more efficient it will be, so in that case a lower kv rating and a big prop is better.

Remember, bigger the prop, more thrust, the higher the efficiency.

curious what other people advise for a good setup for this plane WITH fpv setup...

I would like to have the b2 at a cruise speed of 40kph, at max 50% throttle.
I would like it to fly for 30 minutes on 3300 mah including launch and some more throttle

any experiences here to get those results?

by the way, for the people who want to buy it from the NL warehouse:

this probably isnt the best vid to use as an example, but...
Turnigy C2826/1650kv
7x5 APC
30A esc
8-9amps cruise
18-19amps WOT
at approx 50% throttle:
3S 2600mah ~ 15-20 minutes flight time
3S 3300mah ~ 20-30 mins
3S 4000mah ~ 30-40 mins
remember I have camera gear on board, with HD cam, OSD w/ current sensor, and 800mah batt, and flight time vary as according to wind, throttle management, glide time/thermals, and whether it's a low level or high alt run
Personally I reckon if you keep the install light, went for say a 450mah vid battery (I use 800 because it powers the rcRx as well as video), then 3000-3300 would work nice, depending on motor/prop combo

That would help us out as were trying fpv for the first time and not sure what size we might need but with that set up you could stay up for a very long time.
here's some pics of a 3S 3300 nano, & 3S 4000 blue brick
removed the foam hump in the cockpit & a couple of the vertical foam formers in the nose, makes battery install a cinch
