"Thanks for the firmware and motor data.  I ended up loading WiiESC on my F30A ESCs with RCTimer 5010kv motors (on 15x5.5 props), I'll be using 4S.  I'll be maidening this weekend, so results aren't known yet.  With my initial setup testing I did…"

"The first time I tried my 5010 motors on SImonK I do remember hearing some 'cluncky' noise.  I thought it might be the motor...maybe it was cogging instead.  I'd had cogging with NTM motors and old SimonK, but the newer SImonK took care of that. …"

"Old Simonk firmware did have some cogging with some motors.  That was a long time ago though.  The latest Simonk works fine without the cogging.  I noticed cogging on some of my motors a few year(s) back.  I reflashed the firmware (from Sep…"

"Thank you Murray.  I'll have to retry mine with a little more forward c/g.  First is to get some more ESCs...I just 'borrowed' the ones from the Folding Quad for another project for a upcoming trip."

"Murray, could you  post where your quad balances (perhaps xx mm in front of rear frame, etc).  I balanced mine by the 1/2 distance between front and rear motors.  This lead to my 4000mAh battery hanging behind the rear of the rear frame piece. …"

"I just did my back yard maiden...flew good.  As others said, it is quiet.  I've got one prop that isn't tracking right...I'll work on that.  I also seem to get a little bit of a fluttering sound when moves around in flight some...almost like some…"

"@Murray,  Thanks for the infomation.

@MDRM,  Thanks for the CG location.  I had calculated about 12mm forward of the rear plate...I'll readjust for ~20mm.  I was also thinking of longer rear arms and reduced sweep to get closer to a 'square'…"

"Daniel,
I thought about the noise issue.  I'm not running APM 3.x yet.  I thought about putting the ESCs out on the arms for some cooling and keep the center area a little more noise free.  For now I left the motor wires long, and put the ESCs in…"

"I did my first c/g check last night.  Oops...even with two 4S 2650mAh packs on the back frame it's still a little nose heavy based off the 'half way' balance point.  That's with a GP sitting up front...but I'll be adding a little more weight with a…"

"Got it, thank you.  I'll do the mid-way c/g then.
I'm working on mounting my ESCs now.  Wiring routing, clearance, and ESC mounting is actually a little more problematic than I had originally expected.  I'll get it sorted out.  I took a (better) how…"

"I'm getting ready to mount the electronics on my frame.  To verify, where exactly is the c/g?  I'm used to using the cross sections where the diagonal lines cross from opposing motors.  I saw mention earlier the c/g should be determined by the…"

"I just received my order from RCTimer.  All I can say is WOW...those 5010 motors and 15" props are HUGE.  I though the 10" props were big enough...these things dwarf the props I'm used to.
I've got my aluminum square tubing in hand as well as the cf…"

"I like the flight 'box' Murray.  The folding quad fits nicely.

I finally ordered the parts for my build.  I found I already had some proper size c/f tube on hand...much thicker than the crossbow bolts.  I've got some 1/2" sq aluminum tubing in the…"

"Well, I'm getting closer to actually getting started.  I've sourced some 1/2" square aluminum tube and some C/F tubes that should fit snuggly inside...just have to place the orders.  I'm still floundering on the motors.  I'll probably wait until I…"

"Yeah Alex, you're probably right.  I've had many RCTimer motors and no real problems with them.  I was thinking of buying 'quality' motors once vs good motors and then wanting to upgrade to better in the future...costing more money in the long run. …"

"Alex,  for after purchase support you'd probably be better off with RCTimer.  I haven't read a lot of good customer support from the Goodluckbuy and other such shops.  I could be wrong, but for their price for that 5010 motor you could buy known,…"
