Initial safe motor timing for Leopard 4082 1600kv?

[izcain]

Just wondering what everyone thinks is a safe timnig setup for starting on a 1600kv 4082 leopard motor. Also what is everyone else finding as optimal timing?

[Fluid]

Start with 10 degrees advance. "Optimal timing" depends on the application, not the motor. How many cells will you run, how many amps will you draw? Sport running or SAW type running?

I kinda figured that the optimal timing would be on a hull by hull basis.

This is in a cf daytona with a Seaking 180A esc and going to run 6s

I am looking to do some sport running at first then graduate to quicker speeds as I get the bugs worked out (me included in those bugs lol)

Mine runs from a SK180 also. My timing is at 11.25 degrees. I think thats what the programming card says. Its the only 11 degree timing option anyway. Use quality batteries and start with an X445 prop. Ill post a link to some new, interesting batteries Ive yet to try, but have good reviews from a few racers here.

Id run two 3s packs in series.

my leo 4082 1800kv is at 11.25 right now. it just "felt" better to me. i have no technical jargen to back anything up heh… but i did try 7.5 and, i dunno, it just didnt feel right. optimal for me is what felt good, so ill prolly blow it up but w/e lol. its a mean machine hull 5s m445

I was thinking I was going to run some nano tech (I have had good luck with them) they are 45c rated 5k mah

I figured I was going to start with a M445 prop and work from there. Is there a difference between the M445 and a X455 Seemed from the specs that they were one in the same?

[dana]

yes, the m prop have the tongue removed… same prop other than that

[dana]

i think the x445 has a larger hub size as well

[LarrysDrifter]

M series are de tounged. They unload the prop a bit more an can give a bit more top end speed. Use the X series first for the maiden. Only progress to more aggressive props after you verify temps are in check.

Dana, why are you blue? Cant breathe?

[izcain]

I thought that a detounged prop is easier on the motor?

[dana]

i hold my breath when i play guitar lol

You will have more traction with the X prop and less cavitation, the opposite with an M prop. De tounged props cavitate when accelerating from a dead stop or coming too slowly out of a turn. This has been my experience anyway.
