I recently re-powered my MG with a seaking 180 and a leopard 4074 2200kv.Just out of curiosity what timing in degrees are people with similar setups running?

I run my leopards at 15*, works good for me on my 4074 2200kv and 4074 1774kv both on seaking esc's. Your seaking 180 should be default at 15* if im not mistaken. You should verify to check anyway though.

Thanks Diesel,normally I would go down to the for a little test and tune but everything is frozen over.By Sunday the local lakes should return to their liquid state.Watch out for icebergs...LOL:Sinking:

No problem. Make sure you get some video with your new setup. What prop you plan on running with that?

The 4074 Leopards are "Y" winds so they can use plenty of timing advance. "D" wind Leopards should probably use less than 5 degrees timing advance. Those would be some of the 5692s and 3674 motors. Check the specs here: http://www.leopardhobby.com/enindex.asp

Ive tried numerous props so far I like the X642,dying to get my hands on a M445,from what I read its your personal favorite.

Yup that's an AWESOME prop. Ran that prop on my 2200kv leopard in my Pursuit 32" mono on a seaking 180. I ran that motor on 4s2p with the m445 and the motor never broke 100F! Moved up to a x447 now, soon as the weather breaks I'll test it out.

What batteries you plan on using? 4s2p would be best, but I never tried to stick 2 4s packs in my mg. So not sure how heavy she would be. I just ordered some 2s 6000mah 25-50c and 3s 6000mah 25-50c nano-techs from HK, dying to try them out. on 4s, 5s on my MG and 6s in my HOTR twin. (soon as I finish building it :tongue_smilie:)

Try a grim 42x55 as well, I think it runs slightly better then the x642 in this hull with stock power.

I'm using 4s2p and 5s2p,did'nt want to try 6s2p until I upgrade my deans to bullets.

4s2p is great, your not gonna want to run anything higher then 4s on that motor though. The motor can handle the voltage, but the rpms will be way WAY to high. A safe target range for unloaded rpm should be 28-30k, (under 35k) for single motor applications. Your at 32k unloaded already which is good. 6s on that motor would be almost 50K rpm want to much. Upgrade your deans before you even run that motor, that motor pulls A LOT more amps then the deans can handle!

Once again thanks for the great info!As you can tell I'm new to the FE thing and I have alot to learn.That is actually great news because I am trying to keep my hole fleet on 4s2p and around 50mph.I already have 4 pair of ose 6mm bullets,should I use these or get 6.5mm connectors?

I think you meant 4s2p, 2s2p wouldn't get you very far, but everyone has to start somewhere. For props start with some CF props like a CF40, CF42 and a CF45, real cheap and good for testing. See what your boat likes the most. The CF props have the same pitch and diameter of the x4 series props from Octura and sharpen and balance it. So if the CF45 work well then a x445 would be a great choice ect.

When you get bored start reading and theirs a lot of people that know a whole lot here. Fluid from a few post above is a great source of information and knows his sh*t.

Take your time and don't rush, most importantly be safe and have FUN!

Here is a low quality video of my new setup.All the lakes in my area are still frozen so my only option was a fast moving narrow river.I ordered 20 sets of 5.5mm bullets but I wont have them for a week or so.I kept my test runs timed to one minute and used the lamest batteries I own (losi 2s 20c hard packs) trying not to melt my deans.The tight running area was cramped so I had a hard time opening her up. c5Hj0GoHkt4

Did you modify the mount to make the motor fit?

Nope,it bolted right up.

I am using the kintec version 1. I machined the lower portion for less drag.

Wow, I want that boat as soon as the ice breaks here in Norway. it's been like -20 the whole december , and the forcast say it's comming 40cm of fresh snow this week , so I quess it's a couple more months down the road. Anyhow, what kind of bullets is recomended? I have deans in my surge chruser now, but with a seaking 180 and 6s i want to change those out, and when getting this boat I want to have a stock of those. Anything from hobbyking?

Awesome Video and great info in here.

I'm sorry, I don't mean to thread jack but instead of starting a new thread I'll just ask here since the topic is motor timing.

What should I set the timing at with this setup?

T-180A and CC 1800kv outrunner.

With an outrunner try default timing on that seaking 180 as well. Default should be 15*. That's where I would start.
