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.

IMG_20140420_194858-1Due the the fact all noise has been banned from our field, (except of course from the geese, motorcycles, tractors, mopeds, powerboats etc..) one has to adapt to the situation. Therefore no moaning, just use whatever you can. I´m having lots of fun with my Orion/Insider. After the mishap a while ago, things seem to have settled. I´m using a 14*10 prop now, and get up there ´real fast´. Could do verticals, but it is sometimes hard to see what goes on, so simply going up at an 80 degree angle is good enough. Last time I looked at the logs, I think they show that power is switched off at 100 meters (says the Vario) but it keeps on ascending to 140 meters. Once it goes, it goes!  (For my own record, CG is at 97 at the moment.)

IMG_20140420_133811 Last weekend the poor Blaster suffered a mishap from a pretty violent wind-gust, that lifted both my small Extra and the Blaster in the air and smacked them right into the fence. Not a happy day for the Blaster. There´s some damage on the tailfeathers, so far I´ve fixed things with some tape and it flies again. I´m contemplating if I should repair,  trade up or order new parts.

I revived the Epsilon. Never got the hang of it last year, mostly due to lousy batteries. Today´s efforts were positive, we go up at a reasonable speed, but it is not an Insider! I also need to find more ballast or a bigger battery, but things are managable. I find the flaps extremely effective. You can only deploy them for a few seconds, the plane really stops dead in the air. Fun to watch, but maybe that explains why the manual says to deploy them only. There is a long thread on Rc-Network-de, basically it boils down to:

  • It´s heavier then it´s predecessor. The weight mentioned in the sales-blurb is grossly wrong. I figured that out! Think 3.5 kg.
  • People quickly convert to a 4 cell setup.
  • Flaps need modifying to be able to follow the ailerons.
  • Braking is really effective.
  • Wings are a pain to mount.
  • Mounting stabilizer is questionable
  • Soldering of the elevator wire!
  • Use decent servo´s

Pic below was taken on a Saturday, but due to the restrictions I can not tell you when it was taken.
