What's New:
12/31/00 - Added E-plane to pics area 11/8/00 - Updated links page and fixed some errors on plane picspage. 10/23/00 - Added T52 info in pics area 05/21/00 - Updated Grob plane info and addedbattery pics. 05/10/00 - Updated Facts page and addedMisc Data to data page. 05/1/00 - Posted some End of Charge data, one on/off high amp draw test and corresponding charton my 10 cell NiMH pack. 04/30/00 - I've been busy with real life stuff, a glow delta plane and working on getting new brushless setup working well. The cellsI got are Sanyo 1600 AAU NiMHs btw. I have done a few tests and hopefullywill find time to post them soon. 04/16/00 - Loads of misc 'tidiness' updates to many pages
04/09/00 - My new powertrain for my Grob arrived 2 days ago. Its a Aveox geared brushless 1005Y3+3.7:1 and EZ30 ESC. I've been busyplaying around with it instead of batteries. Also bought their Infinity2charger and have been playing with that. 04/04/00 - Added better labels on comparison
charts. Added pics of 1200 Duracells. Burnt up my powertrain in my Grob the other day; slowly lost power during a long flight with my large battery. Combination of poor ventilation (basically none) and the cheap gearboxare the cause. The gearbox totally went tohell which was causing tons of drag wasting lots of energy making the motorwork way too hard. Ordering a brushless setup soon. 04/01/00 - My new Duracell pack is behaving much better now. Taking normal break in charge mahs and putting out the fairly normal break in mah. Will do true tests soon. 03/30/00 - Hmm..not good. I broke in the pack with a few 1.5Adraws and .5 amp charges. Just did my low amp steady draw test and the pack failed pretty bad. One cell was 25 degrees hotter than the othersat the end of the test. I'm going to have to remove that cell and put inanother one. No data is posted from this erroneous test. Also, I my 500AR NiCad pack has 'leaked'. A whitepowdery crust has formed around the negative poles of many of my cells.This would make sense cause that pack was acting oddly recently. 03/28/00 - Received my 10 Duracell batteries 5 days ago and nowI have my 8 cell pack made and its charging as I type. Tests soon to be posted. 03/23/00 - Most of the charts/graphs are now online for your viewing pleasure. Some links are empty but itsstill a work in progress. Also added one pic in the flyingfields area. 03/20/00 - Added 3 steady high
amp draw tests. 03/15/00 - Half done making my high amperage draw tester.
Slightlyadded to chargers page. 03/10/00 - Added Zagi draw data. Still working on graphs. I'mreally hating the way the Test Data page is turning out. Soon as I get the gfx and most of my data, I'm going to revamp that page for better viewing. 03/09/00 - Added more charger data. Finished one Zagi data
butwon't post till tomorrow(I'm tired) 03/07/00 - Updated Links page |
