If you are using these, it must be nice to be rich.

P.S. I put myself on the waiting list for the ARF (the big one).
AJ,

Not $50+ for a piece of CF tube, it is for one dozen. I'm happy to get my CF from the LHS or HK, but it provides options that others may find appealing.

Home-made pan-tilt system
Microphone
FrSky 2.4 GHz control with Turnigy 9x flashed to er9x.

I want to try to fit it on a Axn to start, but I can see why it would be a challenge. I've cut a hatch on the bottom and that does free up a lot of area for larger items such as the OSD. Oh, and I do have a RCTimer 2200kV motor that I can replace the stock motor with. I've seen some folks post FPV Youtube videos with setups that appear to be heavier than this, which gives me some confidence that it might be feasible.
-----------------
Fitting it all will maybe be a bit of a pain. But the main concern is wing loading. The axn flies very light with a 1300mah battery, and easily gets 15 minutes in the air with that on mixed throttle. If you add 200-300 grams I think it's suddenly more safe to keep timer at 5 minutes. If you need to fly with 2200 batterys, the plane will fly even heavier, so in my mind I think what's best is to keep the battery light and go for short flights with the axn if you have heavy equipment on it.

If the fpv-setup is kept light, and you use a 1300 battery, it will fly pretty much like a no-fpv clouds on a 2200 battery, heavy, but most seem to find that kind of weight acceptable...

Ah. Got it. That makes more sense. Thanks for pointing that out.

Hi.
I need to know how I can protect the foam from being destroyed when I land on grass. Can I use some thin plastic and some how stick it on to protect the bottom of the fuselage from landing? What thickness should I get? How to stick it on? and from where to get it from?
Thanks

I have been using this on the AXN.

3mil on the wings. I put 10mil on the bottom of the fuselage.

The simplest thing to do is go to your refrigerator and when your plastic milk jug is empty, cut off a 30mmx180mm strip and epoxy it to the bottom of the fuselage. It will work even if you land on asphalt all day. You will love the cost of this procedure.

I live in the UK so I think this will do (http://www.ebay.co.uk/itm/Clear-Matt...item2c675b237d) It is 1mm so about 39mil but its cheap.

the no name brand milk bottle and cheaper epoxy will help mitigate the expenses

As AJ says, many ways to do this. Just a thought, if you wanted to take away rather than add material you could slice the motor-pod and small part of the base underneath. Then velcro the cut surfaces and camera to make it stay put. You could also velcro the pod cut-off so that it could be put back when the camera is not being used. Will weaken the motor base slightly but I very much doubt it would be problem.

I will post a pic of it once I figre it out.

I finally got a chance to maiden my "Bruce" over the weekend :P

I've had it together since late August, but had to wait on a new servo (bad one in the first batch) and other life got in the way. My build follows Bruce's YouTube guide, including the 6x5 prop, and uses digital servos instead of the analog ones he lists. Wings are permanently glued in place.

My first intent was to hand-toss the plane hard and see if it had any really wonky characteristics...

So, I threw it level and quite hard... it glided away from me in a very straight line. I wiggled the controls and everything seemed fine. Funny thing is, I was still gently gliding several feet off the ground, so instead of bringing it in I gave it some throttle and nicely flew it up a few hundred feet. It was a sort of unintentional maiden, but really great too.

I used one 2200mah battery, which normally lasts about 8-12 mins in my T-28, for about 28 mins! The combination of WOT and gliding really extended the life of the battery.

I had a really good time doing slow sailing (haven't flown a glider since a Sophisicated Lady about 15 years ago) and some high speed passes too. Did my 1st touch-and-go's ever, thanks to the pusher prop being out of the way. We fly at a rough grass field and don't have gear on any of our planes, so touch-and-go's are otherwise impossible.

It really is a lovely plane to fly and as a counterpart to my more aerobatic T-28 it makes a very nice alternative.

A couple of things I did notice:

1. Getting used to the downward tendency with the pusher prop does/will take some getting used to.
2. The roll rate is pretty slow, which isn't necessarily bad, but I almost got in trouble a time or two, thinking it would roll differently.
3. I'm tempted to do some mixing with the throttle to counteract some of the pusher prop. Anyone had success with that?

That's about all for now. Very excited by the first flight and can't wait to get out again!
