IMG_20140422_142127Yeah it happened again.. Somewhere in the forums you read that the original might have a bit of a problem getting into the air when it is windstill. Yes, I remembered after launching (not hard enough) in near zero wind. Result: An unscheduled landing (to use a phrase I hear ´mericans use when they crash something). The motor sprung loose. Now it was really not a hard touch, but enough for the no-glue to give up.  During the repair , I could not discover anything that could pass for glue at a 100 yard distance.  Anyway, whipped up a bit of my magic potion, and now the motor will never break loose again!

Today I had a few more flights, no problems to report. More work on the CG, I am getting closer to the ´Right Spot´.

With the present setup I reach 100 odd meters in 30 seconds. Compared to the 3 secs on the Insider, that´s an eternity. A Plan is needed. I made a quick set of jumper wires so I can plug in the current sensor that I use in the Extra. When I know what current I use, I can try to find a better setup. (Even one that runs on 4S if needed!)

Update: A fresh new Unisense-E does the job: 61 peak, 50 Amps in climbout. It also tells me starting power is 736Watt, at the top I’m at 550 Watt. This is a plane that weighs probably 3 kg’s!

I’m pleased with the unisense thingy, it’s all you’d ever need for a e-bird.

When the weather changes, I’ll get the vario sorted, I think I’m dropping 70 cm/sec in still air, but hopefully that can be improved upon. Slow speed is not the answer here, keep it moving to get the best sink-rate. It does not really matter too much if it is not accurate, at least not until I get the hang of the sounds.
