ORIGINAL: daubut Nice to see the photos of the TX in hack stage 1. I ordered mine yesterday so when it arrives I will start by removing the case and board and start to shave some weight off mine also. I will probably just solder the cable for my cameras AV out directly to the board removing the connectors. I will post some pics when I get the mods done. I was also thinking that getting the weight down as much as possible would help me be able to install it in a more permanent position closer to the tail of the plane. Trying to get the TX as far away as possible from the RC RX hoping to eliminate interference issues before they arise. I am trying to keep my weight down and trying to keep most additions as close to the CG as possible. I want to try to keep the overall weight of the plane below 6-7lbs. I ordered a larger prop went from a 10X5 to an 11X4 to get a little extra pulling power. With 1.2 hp rating on the OS .46 it should pull the plane nice and docile (I hope). Do you plane to leave the plastic casing off the TX antenna? If so, do you plane to install the antenna in the foam or have it stick out? I have been looking into the foam planes and some of the homebuilt foamies lately and am intrigued. Did you build your own hot wire foam cutter? I saw a few posts about it and have seen some homemade plans for a few, seem simple enough to make one. Great info thanks, and good luck this hunting season! Yea, after having this TX sit around collecting dust for a good year it's nice to be toying with it. When I bought mine I think it was like $50 or $60 and that was (and still is) a great price for a 2.4ghz 2 watt system. Now that it's thirty some dollars how can you go wrong? Don't know if I'll remove the RCA and power jacks yet or not. I would like to take off that plastic elbow and nut though because they serve no useful purpose without the TX case. If anybody figured out how to remove them without desoldering the antenna let me know. I expect you could heat up an exacto knife and slit the plastic eblow down it's side. As for the nut you could dremel it off or something. The AP foam plane I'm building should be able to lift this thing with no problem on a tiny CMOS or CCD camera and probably even with my Aiptek 5100M (4 ounces) pocket camcorder if I want to plug that into it. The foamie AP ship I'm building currently has a 48" wing and wing loading at the moment looks like it will fall between glider and trainer loads. However, if the weight gets a bit higher than I want I'll just hot wire out an even bigger wing to slap on it to get the wing loading about where I want it. Good idea to move it as far away as possible from the RX antenna. On the other hand, using a good full range interference blocking RX such as a JR Sport should probably eliminate any concerns. I'd play it safe and do a VERY far away range test with a buddy watching the plane so you can be sure the RX still has control. Drive a block or so away and play with the TX as he watches what the plane is doing on the ground. As an added precaution I'd give the plane some right turn in the trims before launch. That way if the thing does loose contact it will start doing lazy circles until you can get close enough to regain control. The motor should automaticly shut down on most ESCs if it looses the signal so that won't be a concern. As far as the antenna goes I'm going to leave the plastic sleeve off. Like I said, the antenna wire is real flexible and shouldn't break or loose it's shape even if you cranked it from end to end in a loop. When I mount it on the plane I'm probably going to stick it straight up and down inside the foam and sticking out the top of the fuse. I'm not too worried about protecting it, just keeping it in one position in a way that it won't flop around on me. If I decide to mount the TX on top of the wing the antenna will either point straight up or be horizontal trailing towards the tail. Some people report better reception on other transmitters by having the antenna sideways, others straight up. The main thing is to position your camera RX in the same way on the ground. I'd also mount the RX on top of a four or five foot PVC pipe you stick in the ground just to give it the best chance of not seeing interference. Probably not a big concern with this powerful of a unit. Yep, made myself a homemade hot wire bow and a hot wire table bandsaw style cutter. Both are VERY simple to make and cost just about nothing if you have the parts laying around in the garage. You can go to the thread called "Here's A Simple A FREE Foam Build Plan! Cool Looking Plane Too..." in the foamie forum and read that. WARNING: I'm very long winded in my messages on there but others helped me walk through building a foam cutter, wing jig, and that plane. All the info you need is there. Later on, towards the end of the thread, you can see my final third build version of that plane complete with photos and step by step build instructions. While I'm not using that plane for my AP I think it would be the perfect platform for it. Just scale it up in size to whatever you want wing wise. Dual booms, single aileron, and an elevator type setup. My current AP foamie build is in the other thread in this AP forum under "Homemade Foamie AP Platform" or something like that. Once you get into hot wire cutting foam bodies it will become an obsession. You learn so much more about planes, how they fly, and some rather good build skills as well. Saves you a ton of money and also gives you added satisfaction when you fly something you built from scratch.
