As it is a switching power supply, not a linear regulator like others, it is more efficient (less heat), and rated for 3 Amps continuous (5 Amps for 5 minutes).

[RCSE] Thermal Eagle
Just found a winter project. A Thermal Eagle wing and fuse, untouched. I am looking for any help in locating pictures/plans/drawings/hints that might be able to help in completing the project. Am at a loss for sizing up the stabs and rudder, let alone the facing/hingeing for the flaps and ailerons. What should the ratio be between the span of the flap to ailerons be? The only hint I have gotten from any one is to insert a dowel in the fuse at the point where the Leading Edge meets to prevent the wing from pinching/crushing the fuse on spot landings. Help would be most appreciated. RCSE-List facilities provided by Model Airplane News.

[RCSE] Thanks CASL !
Greetings! Just started settling in here and thinking of the great weekend at the SWC. I want to thank the CASL members for all their hard work to bring us a great SWC this year. I felt the contest was run smooth and the field set up very comfortable. It reminded me of the old field, very much the same feel. The Slow Stick combat was great to watch. I am sure that event will grow rapidly! Congrads to all that placed. A job well done considering the landing conditions on Saturday. I really don't think many, if any made all their landings all weekend. Mother nature did get take a stab at us on Sunday. For those who got hit by the big sink cycle in the last round, I feel for ya! Been there, done that! Thanks again CASL! I WILL see you next year! Cheers Charlie RCSE-List facilities provided by Model Airplane News.

[RCSE] B4 spoiler help please
I've got a 2.6m Multiplex Pilatus B4 acquired 3rd hand (at least). Its the ARF version and I believe the spoilers are factory installed. One spoiler is real smooth and is easily activated with HS-81 servo. The other spoiler is sticky and servo is unable to reliably raise and lower spoiler - I can manually push/pull the cable to activate, but its binding somewhere; I suspect that the cable has been glued to the cable housing. I would like to access/remove the spoiler to replace whatever is binding, but it seems to be fixed to the wing sheeting. Can anyone out there tell me how to fix this problem without ripping up the wing? Thanks for any advice, Richard Seattle RCSE-List facilities provided by Model Airplane News.

[RCSE] 5 cells, current limiter and me :-)
Or Gordy will tell you to switch to Volz servos and 4 cell packs :) One of the problems with using 5 cells is wrapping your head around the new 'bottom'. Flying while with 4 cells@ 4.8v is no problem.Flying 5 cells @4.8v usually turns a moldy intoa plane you can take home in a shopping bag. :-( After flying and getting to know the idiocycracies of a 4 cell pack for most of our lives, 5 cells can trick you into an expensive mistake. Takes some brain engagement at a time when you should be just having fun :-) 5 cells won't get you another minute of flying time or another landing point, but the extra cellcan cause some chaos to components. A stalled servo because of a looked over endpoint causes servo motor brushes to turn into heating elements, connectors designed 20 years ago for use with 2 or three weak servos are still supplied new...and work great...till they've been beat up some plugging and unplugging (sometimes by a crash)don't like too much current (like when you try to pull out of the bucket on a ping launch). ON the other hand, if you're the proud owner of current digital servos, using 5 cells is often recommended, so a current limiter with 5 cells could be sort of a good thing. And of course using 5 cells will make your servos almost as strong as some using only 4for awhile. Servo packages show a rating for 6volts...last time I checked that's not 5 cells...and its not an endorsement for continuous use by the suppliers. All motor and motor controllers for Eplanes show a max continuous current and outputbur are quick to point out for how long before things turn to carbon. That BEC that Andrew showed is a pretty smart system and only about double what the simple systems offer. Its very cool in the fact that you can use it with LiPolyssuper light weight, small size and a ton of capacity with a efficient current limit system. (doesn't waste unused capacity in the form of heat). And thats all I have to say about that ...today :) Gordy Louisville, heading to Indy today
[RCSE] FS NIB Fusion
Hi Gang, I have a NIB Fusion for sale. This is the 4 servo wing version. The plane is untouched except to open box and marvel and Phil's bagging expertise. I am asking $649.95 plus shipping. These planes are hard to get, but this one is ready for immediate shipment. Please contact me direct if interested.

Re: [RCSE] 5 cell current limiter
Bill thats because all RX's and servos today are rated for up to 6v. But if we were talking LiPO cells then a 2 cell pack would need a V regulator as thats rated over 8v.

Re: [RCSE] 5 cell current limiter
He clearly said he wanted to use a 5-cell pack. That is not a problem for any receiver that I know of. Li-Po's etc are different, but that was not the question.

[RCSE] ham license -- off topic
When I got my first amateur radio license as a teenager, back when there were sunspots and the bands didn't go dead at dark, the pinnacle of hamdom was the Extra class license. In those days it required a fearsome code test, 30 wpm I think, and a hard written test made more difficult by the total lack of prep material. I sometimes thought about getting an Extra ticket, but other things intervened and my activity drifted off to nothing. Somehow, 46 years slipped by (and they go fast, don't they?) But last night I finally bestirred myself to drive down to the Cliff Branch library where exams were being given for the Extra license. There's no code test now; the written test is hard (sample of an easy one: if R = 100, Xc = 250, and Xl = 150, what's the phase angle?), but there's plenty of cram-course material to get you ready. So I did it, and now I have the designation that seemed so far out of reach to the crystal-controlled novice, all those years ago. If there is a point to this tale, I guess it might be that we all may have some old goals that haven't been dusted off for a long time, and that it's pretty cool to dig 'em up and take another crack. You might even apply that to flying XC or getting LSF V, and call this a soaring-related post. __ Do you Yahoo!? Yahoo!

Fwd: Re: [RCSE] 5 cell current limiter
Peter ---BeginMessage--- Hi all, You can use the 5cell without a problem if you have long servo leads. I would not use the 5cell an a RES glider with stock servo leads. Due to the longer wire in a scale or F3B, F3J Glider the resistance is increased and the extra voltage is not a problem. And if one cell crapes out you still have 4 more to get you home.

Re: [RCSE] 5 cell current limiter SWC.
Not all servos are rated for five cells. Most but not all. For instance JR's 331 with a 3 pole motor is not. But a 331 has about 20% more torque than a JR 341 and if you drop in a set of JR 368 gears it makes an excellent flap servo. I have been using that set up in a Space Pro without any problems for near a year. Ailerons are 341's with 368 gears as well. Also Congratulations to Chris Corven, 3rd place, RES and Mike Reagan, 1st place, RES at the SWC. Both flying the only AVA's at the SWC. Regards, Dave Corven
Re: [RCSE] 5 cell current limiter
Well actually Bill My answer was in reference to your answer to him, you said I think that you use 5 cells all the time and have never had a problem, so I said that's because you equipment is rated for up to 6v. It seems that gordy doesn't agree about using 5 cells. One thing I have found out though is a 5 cell doesn't seem to last as long as a 4 cell rated at the same ma. Not sure why except maybe the 5 draws more power. BP Bill Malvey wrote: He clearly said he wanted to use a 5-cell pack. That is not a problem for any receiver that I know of.
