  1. That is kind of what I expected....thermal management of LEDs is a big issue. I wonder what Aero-Lites uses for an emitter. The latest Cree XHP 35.2 is about 500lm per emitter using about one amp max drive (12 watts), 18 of those would be about 9000lm. Obviously there is a lot of technical information behind these devices, again a 30 minute burn-in test on a taxi way range with the three above mentioned lights side by side would be most....illuminating. * * * Sorry about that, I simply could not resist. And sorry about that, I am not sure watt's wrong with me.
  2. OK, I got that video posted. There are three separate and distinct products being discussed here, all with similar sounding names. Here are the numbers on all of these, from their datasheets: Aeroleds - Boise, ID - Sunspot 46LX - 70 watts - 7700 Lumens - 150000 candela - Certified $650. 110 lumens/watt and calculated beam angle 14 to 15 degrees to get these results. Landing/taxi light combo. Aero-Lites - Thomaston, GA - Fusion 46LR - 51 watts - 5200 lumens - for 10 deg beam angle it's about 170000 candela using 14 of the 18 emitters for the narrow beam. Non certified $159. About 1
  3. Oops, video did not upload, will put it up tonight.....
  4. Here is the installation of an Aero-Lites Fusion 46LR in our 1977 Mooney 201. $159 versus $599 for the Whelen Parmetheus Pro PAR46. The latter likely has better performance, though, it appears to have very late emitters and reflector/heat sink design. Here is a video as well: Fusion 46LR.mp4
  5. Hi everyone Here is a play back of an M20J Vz climb profile, starting at the POH initial climb speed with TO flaps of ~72 KIAS. I was a little fast and labeled the segment as 75 KIAS in the video, but the POH number is 72 KIAS. I also said 75 KIAS is the POH speed, it's actually 72. Turn up the sound for narration. [edit: I may re-do the voice over and cut out a couple of flubs with the visual overview display] Then the transition to the Vz profile [113 KCAS (115KIAS) -> 500 fpm -> Vy] is flown and shown in the video. I made another mistake in the voice over, Vz for this airpla
  6. How magnetic? This magnetic: Magnetic Bracket.mp4
  7. We had this issue. The center post is non magnetic stainless steel, but our compass mounting bracket was regular carbon steel and highly magnetized! Replaced it with an aluminum bracket and non magnetic fasteners and the problem was solved.
  8. And @y2kiah I like how you present your data! I am going to copy that shamelessly.....
  9. Correct, -a-. I see my Cloudahoy data was from the iPad internal GPS even though I was BT'ed to a GDL 52. Hmm.
  10. I am pretty sure I got about what you did, this airplane has other drag reductions as well and the gains start to diminish after several have already accumulated. I will need to make some more data runs, it would be better to quote a speed at max gross and standard day conditions, and I was pretty light yesterday and it was cold. BTW I get TAS from a couple of different sources, one from the Aspen display (but it is 2 knots optimistic on the indicated due to the Mooney's position error correction, with down path errors when computing true airspeed) and from the computed TAS from Cloudahoy
  11. Hi everyone Finally got N201JX airborne today after way too long, with a new Aspen display, EDM-930 engine display and some other goodies. Took out a bunch of old stuff too and our corrected empty weight (including oil but not unusable fuel ~15lb) is 1750#. I am now FINALLY able to get some much higher fidelity data off this airplane. One of the first things I wanted to check is the max level flight effectiveness of the Lopresti SCRAM (super clean ram air mod) at full power and low altitude. Here is the plot: Bottom line is a 1.3" manifold pressure increase. The hp from Be
  12. Hi everyone I have a new surplus radio master switch/circuit breaker, this is Mooney part number 930023-313A. It is a Klixon style switch with a 3 amp rating: Lake Aero Styling is out of stock on these and their last selling price for this part was an incredible $535.71. See here: https://lasar.com/switches/rocker-switch-radio-master-circuit-breaker-930023-313a I would like to get $150 OBO plus shipping (USPS Priority Mail works pretty good). Send PM if interested. Note this is a regular 3 amp Klixon 20TC2-BB-3, where the BB is the rocker color
  13. Rags is correct, I have accessed the configuration pages on the Garmin 430 myself to correct a very similar problem. And it worked.
