ESC upgrades?

[archuraas769]

Im going to start running 6s lipo 22.2V 5000 mAp and my stock UL-1 ESC cant handle that, any suggestions as to a better ESC that wont cost a fortune?

[Diesel6401]

You wanna run 6s is a SV? WOW, what motor? As far as your question goes a seaking/turnigy 80 amp hv (depending on motor) or regular 90amp or 120amp esc will do, a swordfish/ aquastar will also do.

WHOA WAY TOO MUCH... 6s on that motor =

That's over 50,000rpm. As always it's your choice but I HIGHLY recommannd not doing that. Your target goal for the most part should be 28,000 - 35,000 RPM depending on your goals. Give or take a few of course. To get your RPM take the KV x the voltage so 2300 x 22.2=51,060rpm

O OK cool, you scared me for a second lol. A turnigy/seaking 120 should do you fine.

http://www.hobbycity.com/hobbyking/s...hless_Boat_ESC / http://www.kintecracing.com/Electrical.html you may need to disconnect the bec and run a rx pack though. Let me know how that motor works out for ya I have been interested in it.

I have that same 1280 waiting to go into a 35- inch mono on 6s. I havent seen anyone else use this motor yet. Curious as to how it will perform.

[Diesel6401]

I have a 11xl i wanted to use in a df33 copy, but this might be a better choice. hmmmmm, well i have time to decide

Diesel, whats your speed estemate if i run my ammo 1280,Turnigy Marine 120A Brushless Boat ESC, and 6s 5000mAh lipo batterys?

[forescott]

Using OSE's calculator, you're lookin at 40mph on the stock 40mm prop. Of course the ammo can handle much more prop than the stocker. Sorry to butt-in Diesel! I could'nt resist.

[archuraas769]

[archuraas769]

Well with the right prop ill say ummm 50mph only because we all know what happens when a SV hits 50mph lol.

When I enterd in the info with the cf45 I got a 46mph with the speed calc.

My ammo 2300 always ran super hot on any prop 40mm or bigger. Impressive speed though!
