Noise electrics and TT conversion in the Bee
#1
Thread Starter

I did manage to get the Bee up a few times the last couple of days in spite of the wind. Intresting enough flying at the "electric site"
being boxed on 4 sides by expensive homes there has been noise complaints some the the electrics are large brushless motors with gearboxes and emit a high pitched whine that does travel. After taking off the Bee one of the Residents came up and asked about the
aircraft the sound was INAUDIBLE 50 or 75 ft away and he made a very positive comment on its quietness. May it should small diesels only allowed (just a joke) Of course many of the small electric park flyers are quiet. But some of the stuff is large 40 size conversions
which do to size could be a safety issue, the field is not the big, and the perimeter is lined with sidewalks and benchs and of course
people really not the place to fly large RC regardless of the power plant
Back to the Bee it is quick, flying most relaxing at 1/3 to half throttle is all thats needed. putting around like Bees should now that I have a handle on it will try some acrobatics next time martin

Good show capin, larger props slower rpms. I just ran re-ran my ena 25 D tonight 11v6 zinger 8000 idle 2100 when this gets in a plane
with piped exhaust it will be fairly quiet at 2100 just a little putt putt sound and whoosh of the prop
I was going to fly my decathalon but threw the prop screw and spinner could not find it in the grass my 1/2 A sullivan starter spun it off
LHS did not have one so they had to order it has the 074 norvel in it 3.5mm screw the 061 was too small either 2.5 or 3 mm
maybe by next weekend
Interesting fact on the enya 25Diesel on the exploded view of the engine and parts list they use a different liner and piston not the same as the glow version
I thought all they did was put on a diesel head
