RE: .049 bipe?
I remember back when I was doing my guillows DR1 r/c .020 conversion another guy was building the same kit and said he was going to use 4 channels and power it with some kind of .030 (sounded heavy to me, but I don't know)? I forgot the name of the motor but it had a r/c carb. That little bipe is too cool. I just looked at all the elecrtic power gear that go's in this plane and it's all VERY light weight stuff. I bet you could ARF bash this sucker a bit use an .049 and make a pretty cool little 1/2 A bipe.
They sell some extremely light servos, so maybe even like a 3 - 4 channel setup.

I like the concept but the price is NUTZ! ! ! !
When I think what $70 will buy in the ARF field these days this just doesn't make any sense.

Man, it's gonna take a whole lot of those to make twenty bucks worth of wood and covering at their price![sm=lol.gif] I say go for it Rog. While I have seen some .25 size ARF's in that price range, there's not much demand for them. Not so for the newer electric ARFs.

Yep it was the G-mark. The way I see it with the price thing is it's a take it or leave it situation, you could design and build a similar bipe for a fraction of the cost, but I guess it comes down to how much is your time worth to you (per hour for example)?

Not only that but add up all the special light weight hardware you would have to buy I live in hawaii so by the time I oredered every thing to just complete the model to ARF out of the box level I would have spent way more shipped. Honestly $70 seem's like a real fair price to me.

Paulsen, apparently my time is worth about $0.23 per hour. Cuz it takes me forever to finish a project.[sm=lol.gif] Hey, there must be more people that feel like you do. Demand is all you need to get a high price for something. If that thing costs GPMD or Tower more than ten bucks each by the time they hit their shelf, I'll kiss your grits.

RE: .049 bipe?
It may only cost GPMD or tower $5.00 to maufacture, question is how much does it cost a copy cat builder in time/money? The average builder capabile of designing and scratch building a copy of this type of bipe would most likelly have a bunch of balsa/hardware/and most other stuff needed to scratch such a project (I could build 1 for free using what I have in my garage).
It would take me a very long time but I could copy/build one, or I could have one ready to go in my hands by next sunday via ARF.
The more important question is how would it perform with a glow conversion, and who has any tips, suggestions, or ideas for Rog?

RE: .049 bipe?
There's probably no converting to do. It appears to have a solid firewall, but I'd probably laminate some 1/16 ply on the front. Otherwise, it comes down to fuelproofing a tank compartment, etc. Rog already knows all that, though. I imagine that he was just sharing the find instead of looking for a step-by-step.

RE: .049 bipe?
Is it just me or do most of these 3D models seem to fly nose high? I just watched the video and even when flying straight and level the plane was in a nose high attitude. Maybe that was intentional on the pilot's part, I don't know. The thing about converting it to glow is that it's not really designed to fly straight, fast and gracefully (although, maybe it can). The size of the control surfaces are so exaggerated that it probably does better at slower speeds with a big, high thrust electric prop. That style of flying is a lot harder to pull off with 1/2A. Sorry, rog, I can't see it making a very good 1/2A model.

RE: .049 bipe?
The intended outrunner motor designed to mount on that fire wall is so short and so light that you would have to cut back the fire wall if you plan on mounting anything bigger than an .020 I would think.
Some guy's have there CG set so far back that their planes do fly tail heavy. I find that there is a happy medium and am able to fly strait lines level then hammer it into a wall and begin my hoverbatics with no compromises. Balancing is a key factor in 3D birds.

RE: .049 bipe?
It is a very nice bipe that would be worth scaling up to 3/4 A size for a .074 or hell even a .40 size. If I only had the skills to build as fast as combatpigg I would be set.

RE: .049 bipe?
Anyone can build as fast as me, you just have to lower your standards. Really, I'm not kidding. The 3D models need to be balanced aft to improve pitch stabilty in a hover, to make climbing flat spins possible and of course to make the plane capable of swapping ends like right now. I can't picture any model being light enough to get true 3D antics out of a .020. A .020 in this bipe could still be fun, I would get a print out of that picture and draw it up to build over, then buy about $5 worth of wood and build it. Use bamboo skewers for the interplane struts.
