Esc caps on fire

[dana]

2200kv with m440 IMO. If all is good go to m445

It's 24mm and yes it does

Sorry I meant between a 3674 and a 4074 I now know I screwed the pooch on buying the 3650... Live and learn I guess... It's only money...

You could run the 3674 on the 120. You would need to upgrade esc if using the 4074

Do you happen to have a educated guess on about how many amps the 2200kv 3674 pulls?

you will be just about maxing out the t120 as far as amps goes

Depends on the prop

i had a 3674 2200kv on my old rigger pulling over 120amps

So t180 or what about the swordfish 150?

I am using the 4074 2200kv Timing at 15 with a T120a esc with 3 more 35v 1000uf caps with a x646/3 prop,
In a modded to FE 36"PB Shockwave mono and all stays cool on 4s2p a 42 mph.

I thought your setup was 3s until I read further down. Generally guys limit 4s "sport" setups to 2200kv, and reccomend a 200A+ ESC for doing so. I would also reccomend a larger can and lower kv, but no matter how you do it, your ESC will limit your potential power.

OK, so now you know you had a small motor with high kv, but moving on, the 3674 2200kv on 4s is a huge upgrade especially if you get a 4 poler like a Leopard. You can run the T120a ESC with that setup all day long if you keep the prop at an x442 or less. I ran it in a Mono and your cat will pull less amps. To answer your ballpark figure, I think the setup i mentioned above will pull around 90-100 amps with an x442.................so you will be putting out around 1400 watts, or 2 hp...........big power for that hull! It'll get you over 50 mph. The 4074 is even more overkill and will not yield much more speed.

Thanks wake...I was worried about putting up my post and looking stupid. But for the most part I got some good info... all the members of this forum
Rock but you and keith and some of the other more experienced members are in a different league...

If you do go with the 3674 2200kv Leopard or Turnigy, be sure to drop the timing on the ESC to 1-3 degrees. They are D wind motor & don't like a lot of timing. 15 degrees will not do it any good at all.
All the best.
