RE: what methods du you use to balance your jet
I tape a piece of triangle stock at the desired cg point, one under each side of the wing. I then place the plane on a couple of saw horses, bricks, or whatever works so the plane pivots on the triangle stock. For me, it's quick and easy.

RE: FAA seeks to restrict model aircraft flight
I hope Keith chimes in. This sounds like the state of affairs 3 to 4 months ago. The article showed up on Aero-News yesterday, but is this article based on current info provided by the AMA? I checked the AMA website and there has been no update in the government affairs section.

RE: Duralite Batteries - Sizes/Requirements
Bob, I have used 2300 mah duralite plus in a dual battery setup (2 batts, 2 regs, 2 switches) in one mid size jet and two large jets with digital servos and have always had more than enough amp hours to handle up to 6 flights. I am not using a powerbox.

Thanks icepilot. Believe it or not, I try to do all the things you suggest, but it is difficult for me with the little handycam. I get a bit better as I practice, but I'm only shooting occasionally. The editing software is Windows Live Movie Maker that can be downloaded free for Windows 7. It isn't sophisticated, but that is a good thing for me! :)

Rob put the first flights on his new Yellow F-15. He did a superb job of building, painting, and detailing this bird. The first pic is of the 'Three Amigos': Rob, Joel, and Tom.

RE: Unstable travel adjust setting 12X/1221/8611
Thanks for all the replies. There have been several questions regarding setup. A few comments/answers: - This airframe with transmitter, receiver, and servos has been flown 100 times over the last year without incident. The intermittent failure began this weekend after 100 successful problem free flights. - No matchbox. - One channel per elevator servo. The channels are mated. The mated channel is inhibited. - I have methodically activated every switch and knob to determine if there is some oddball setting or mix that could be giving me difficulty. I cannot reproduce the problem I had this weekend. - The elevator linkages are nearly, but not exactly, the same. The programmed right and left servo travel to achieve proper elevator throw differs by 1 to 2%. If I can't get the system to act up again, I'll replace the elevator servos and extensions and then hope for the best. My first thought was that one of the servos was at fault - what confuses me is that the servos hold center and operate smoothly even when the elevator travel has gone whacko.

RE: Unstable travel adjust setting 12X/1221/8611
[quote]ORIGINAL: basimpsn Could be a switch still active. Next time check your radio servo monitor to see if both elev travel is linear. [/quote] Could you elaborate a bit? Switch settings are identical/unchanged when the problem arises. Servo travel on the servo monitor is the same for right/left elevator. However, travel is not "linear" as I have some expo programmed.

Unstable travel adjust setting 12X/1221/8611
I posted this in the JR forum, but I've not had any useful responses. I thought I'd check with the JR experts in this forum. I'd very much appreciate it if we could avoid another radio flame war. I have an unstable travel adjust setting that nearly lead to the loss of my 1/6 F-16. 12X radio/1221 receiver/8611 servos (one on each stab, one channel per stab). The airframe and all components have flown for over a year and have about 100 flights on them. I pulled elevator on a down-line and the plane rolled severely. I landed and did a thorough checkout. Both stabs were properly centered. However, the right stab had several degrees more up throw than the left stab, and several degrees less down throw than the left stab. The travel adjust settings in the transmitter had not changed. I checked the next day and the elevator throw was still screwed up. However, I checked this morning and elevator travel was correct, so the problem is intermittent. The only change is that I flew a different model yesterday, so I went through the model select procedure twice in the transmitter. One of the servos would seem to be the likely culprit, but both hold center. Both servos operate smoothly with no jitter or jerkiness during actuation. However, the variable/unpredictable up and down travel is a serious problem. I was going to do some diagnostic work with different servos, but now that the system is working properly, I'm out of ideas. Advice would be most appreciated. And again, please avoid a radio flame war. Thanks, Bob

RE: Unstable travel adjust setting 12X/1221/8611
Zeeb, thanks a bunch for your post. I had battery problems with my 12X from day one, so I changed to eneloops which have been great. My transmitter battery was fully charged the day that I had the elevator malfunction, and it was somewhat discharged from weekend flying when I checked this morning and elevator travel was normal. I don't think it is a transmitter battery problem, but again, thanks for the post.

RE: Full scale flying experience…help or hindrance to r/c jet flying?
Amazing story Tom. Modeling saved your butt! Most of us have seen a model flutter, usually with something ripping off the plane, but the pilot always lives to tell about it. Likely not the same for full scale pilots. I've seen full scale pilots doing advanced precision RC aerobatics within a year or two. I've also seen full scale pilots that could not get out of the cockpit and never advanced beyond RC novice. Many of the best RC pilots I've seen have never flown full scale. It is always good for an RC pilot to make the effort to understand basic aerodynamics. A little time and reading will save a lot of grief and several air frames.
