This morning I finished a 1/2A size Brodak Twin Mustang converted to ECL In a fit of "ECL Evangelism" I posted it over in the 1/2a forum. Fun project so far, and am looking forward to test flights - just cuz its so cool!
The power system is two of the new Brodak 1/2A power systems that are due in by the end of the month. Same system I had on the Baby CLown at the Fly-In back in June. Set-up to run on two ESC's but one batttery & Timer.
Question for the ECL group - especially those of you with TWIN experience: What shall I expect the power usage to be?
More Background: The timer is hard-wired for full throttle operation for 3 minutes - no adjustments. On the Baby Clown it uses 320 mah turning a 6x5.5 prop. The F-82 uses a similar wing to the BC but stretched with tapered outer panels. THe BC weighs about 8.5 oz, the F-82 wieghs 12 oz.
If everything else were equal I would expect the load on each motor to be LESS than it is on the Baby Clown, so current draw on each motor will be less than 320mah. I would not expect the twin to fly much faster, but I'll bet it NEVER slows down! in total I expect that the current used will mostly reflect two sets of motor eficiency losses - maybe plus a little, but that the total current draw will be much less than simply doubling the current used by the single.
Experience or opinions anyone???
