| jgood | 17-Jun-07 16:46 | | CD-ROM motor now mounted, upper and lower wing leading edges sanded. AUW currently coming out as 4.4oz. Seems to balance with the battery behind the firewall, and the servos in the cockpit. |
| Xanadu | 17-Jun-07 20:46 | | Do I see, in the very bottom right lower corner, I pink bunny slipper, and 2 little beady eyes looking out?
|
| jgood | 17-Jun-07 20:51 | | Yes, hired security (currently at rest), designed to keep Russian frogmen away from the latest in Fokker technology. Think I might be looking elsewhere though, progress hasn't been swift around here, and I'm sure I saw a glimpse of a black wet suit on the balcony last night. |
| John M Oshust | 18-Jun-07 10:13 | | I just checked and my Yegor is pinned thru a flipper to my building board. Am I correct in assuming that the motor to power this plane will me from a CD rom? Interesting someting to do with my old hard drives! |
| Mike-A | 19-Jun-07 06:41 | | James did you rewire the CD rom motor? If so what was the gauge used and windings. I have a rewound one but it cannot do the job. |
| jgood | 19-Jun-07 07:34 | | No, it's one of the old Lens RC ones, Mike. 17 turns, I think.
John, yes, you can take the motor out of an old CD-ROM, rewire it with thicker gauge wire, and use it. Very quiet (if used direct drive), and very efficient. http://www.gobrushless.com |
| mikemolt | 21-Jun-07 10:36 | | James, looking good...did you decide on the ailerons yet? The lens motor should give it more than enough kick for sure! |
| jgood | 21-Jun-07 20:44 | | Mike, I'm going to try a 4.1g servo in the top wing, and sullivan cable, ala your Hellcat. I didn't want to go for full-length ailerons, and my torque rod thing didn't work. I think the guage of wire I used was too small, and it had too much slop in the action. |
| mikemolt | 21-Jun-07 22:11 | | I think sullivan cable will work just fine too actually... I'm made a discovery while using Sullivan cable not long ago actually, something I think would help a lot of folks using it. Nothing earth shattering, but it sure helps when you have too much friction between the cable and outter tube of Sullivan cables due to a lot of bends or sharp bends. If it seems the servo is working too hard or binding, and that the ailerons aren't going back to center b/c of too much friction, just unravel one of the smaller wires that make up the cable. It might take a few wires to get the smooth action you're after, but it sure helps.

| John M Oshust | 21-Jun-07 22:14 | | You guys make me fell so stupid, as I do not what you are talking about! |
| jgood | 21-Jun-07 23:04 | | Good tip Mike, thanks for that. Do you think the reduced strength of the cable will cause in flight failures? I guess I will have to do a lot of testing for I get FAA approval. :) John, I don't know what Mike said either, although he designs incredible flying models, I'm not sure he knows what everything he says means... |
| mikemolt | 21-Jun-07 23:09 | | Ah James, you rascal, I'll get you back for that comment. ...but on a serious note, you shouldn't have to remove too many of the wires in the cable. I removed two or three on my Hellcat and haven't noticed anything too bad...well, there was that time it did like 16 rolls without me trying to, but I just figured it to be a radio glitch. ;-) |
| sweetwillie | 21-Jan-08 11:03 | | Pure genius!! Are you guys sure that you're not secretely, magicians? I mean, none of us 'mere mortals', have the finesse or skill to do this. |
