I got my CC35 today, tried gov mode for the first time.

Ive set the gov mode to "gov high" and put in a throttle curve that looks like 0-85-85-85-85

After a 10 min flight the motor was burning hot, With my old Align 25 ESC it was never even close to getting hot.

Tips are welcome.

Setup

Mega 16/15/3 - 13T
CC35
TP2100

As stated, 13T, and it was a clean swap, only the ESC.

hmmm...

i'm having strange probs not far from that either........

i'm on lehner with CC35 and 11 tooth, 315mm blades (not as bad with the CF blades, but the woodies are horribly draining for some reason, still everything is getting over-hot... prob is not as much the motor, although it is getting pretty warm....

but i'm stuck with 5 minute hover times on TP2100's and Tanic 2220s'......... and my electrical system is overheating somehow... getting battery-to-ESC JST connectors melting together in flight (just hot enough to start sticking together, causing me to be unable to separate them at the end of the 5 minutes when my soft cutoff breaks in at 9V setting.

running gov mode several different settings from 60-85%.... all of the settings are doing this, ranging max headspeeds tried so far are 2300-2600........

don't get it? i am waiting for a 10t pinion to arrive, if this doesn't solve my probs, i'm at a loss... i will then assume i've got ESC probs? who knows? i'm also going to upgrade to Deans connectors, but other than that... .i've obviously got some unusual amp draw going on........ previously had no problems using Align 400s, Align 25ESC, 100% throttle, 15t pinion-- which got 12 minute hover times and 2250 headspeed.

is it a bad idea to heatsink a lehner?

Are you using those tiny jst connectors as in the kind you find on
a micro heli HB picolo etc ?

Those seem way to small for 20-30 amps.

Wildcat Fuels

They ARE way too small- JST connectors are good for ~5 Amps at best... Once you go over that, they get really hot and add alot of resistance to your wiring. Deans Micro are good for ~10 amps or so and Deans Ultra are good for maybe ~50ish. Go get a bulk pack of Deans Ultra connectors and replace all the ones on your batteries, ESCs and chargers. You'll be glad you did- If you use them in other plankers or something, make a few adaptor harnesses.

...

thanks guys....

yeah well the jst little ones were working with the 400s and 25 esc, where i was probably pulling 16amps, but yes they did get warm, and now with the Lehner and 35ESC they are starting to melt (oops)... so point taken, albeit about 4 months too late .

really i knew the jst's were too small, but i was just too lazy to get of my rear-endo and replace them... dummy me

course last night i decided it was time for upgrade and while ordering a CSM gyro i also ordered enough Deans Ultras to replace all my batts, my ESC, AND my charger... so that advice DudeVT fits the bill quite nicely.... i almost ordered the micros, but thought i better go with the 'ultras', based on their title alone.

thanks guys.... now on to my 4 minute hover times......... hope this is just a result of using an 11t pinion with 315 woodies and a lehner... i need a 10t for that according to most of what everyones told me. but it hasn't shown up yet.

oh yeah and don't forget the almost probably 22 gauge wire that goes with those jst connectors, all of about the same diameter of a toothpick or less... hehe. dum dum dum!

Im seeing the same question I asked on several boards, people having trouble with heat on the Mega 16/15/3 + CC35, something is fishy...

Gonna switch over to Fixed mode tomorrow and see what the temp going to be on the engine.
If that works then Im gonna try and downgrade the software revision on the CC..

Note: Was flying in 5 degrees celcius and you could touch the engine for a split second withtout getting burned after 10 min of hovering and FF, what would have happened if there was 30 degrees outside?

I changed to fixed mode, and also I changed the battery connectors to deans ultra connectors

That did the trick, after 11 min hover the temp are as follow.

Motor: 90F
Esc: 92F
Battery: 130F

Gonna try gov mode next with the new battery connectors, see if it was that or fixed mode that did it...
