Default RE: Composite ARF Impact
Hi Guys,

This past weekend I was at a fly-in here in Denmark where Bernd Beschorner (TOC competitor) and Manfred Greve Jr. were present. Manfred brought his completely new Impact powered by an electric motor....!! He finished the model in 3 (three) days, and the all up flying weight with a Plettenberg "outrunner" motor and Kokam 10S3P 6000mAh battery pack is 4600grams. Weight of the battery pack is 1400grams. The outrunners seem to be the new trend, as opposed to the more noisy geared motors such as the Hacker used by Jason and Tony F.

Manfred recently made a test for the German magazine FMT of the most popular electric motors for F3A, and the result was quite interesting when measuring the noise @ 3meters...

Hacker (geared, spur (straight) gears): 93dB
Lehner (geared, helical gears): 89dB
Torcman (outrunner): 88dB
Plettenberg (outrunner): 88dB

Ohhh, and Bernd flew his new Delro 42% Ultimate, beautiful!!!!!

I have attached a few pictures... [8D]
