Think i need more prop

[MAMBA2200]

So i went out to try the new combo yesterday leopard 3674 1900kv and m445 prop and its a very safe combo with decent speed the first run 42.5mph i finally broke 40 whooo hooo temps were esc 98 motor 97 ambient of 86 with a water temp of 76 this is a very cool running set up to say the least on the second run which was made back to back of the first run i got 43.2mph both runs were around 4 min before lvc and the temps were nearly identical with esc 97 and motor 99 so im gonna order a m545 to go on it any other suggestions here is a couple vids i made and i was running 4400mah 40c packs

Put a straight edge on the bottom of the vee and see if your strut is parallel and about 3/16" to 1/4" above. Batteries should be not more than 3/4" from the back of the tray.
With his set up and the M545, I get 45 to 48 mph with stock motor and ESC. Also, I'm using a 4200 mah pack not 5000.

Weight matters.

Found that my expo settings were not at 100% and now it sounds like the motor is twisting also i had added a bec before my last run checked my eagle tree and it has dropped the amp draw by 20 amps b4 bec 121a after bec 101a i like that:D

i ordered me a 5s 5000mah 40c pack for my revolt last night that should be ok with the motor esc set-up i use right????

[dana]

I was gonna suggest 5s instead of bigger props. I wouldn't use the m445 to start I would go with x440 x442 or grim 42/55. Any of those props on 5s will get you into the 50's without blowing anything to start

[MAMBA2200]

thanks dana good info

[MAMBA2200]

well i bought a m545 prop today from OSE gonna try this prop on 4s and just a good excuse to add another prop to my collection lol

[dana]

How did 5s work for you?

[MAMBA2200]

well i havent had time to run the 5s yet but im gonna run it in the next night or 2 i will let you know i was just ordering some stuff for my mystic i just bought and figured i would just go ahead and get one

[MAMBA2200]

well tried on 5s and the esc took a crap on me so i bought a 180a esc for it hope it will work on 5s at least i will have more amp draw room to play with

[dana]

Sorry to hear you fried the esc. Which one was it? What prop were you using?

[MAMBA2200]

it was a seaking 120 it moved about 50 ft and just stopped and that 50 ft was under 1/4 throttle

[dana]

Which prop?

[MAMBA2200]

the stock prop 42x55

[dana]

Hmm that's odd, I'm surprised it blew from that. Doesn't seem over propped really

[MAMBA2200]

yes i know it didnt smoke or get hot and the eagle tree just said it had a draw of like 32amps it just died would not do anything but there sending me another but i went ahead and bought a 180a anyway

I am a new bee but could I run my ESC / MOTOR / BATTRIES with Eagle Tree on a ducted fan deal to check the load? I know it will not be the same as the boat just thinking.

[MAMBA2200]

yes you can use it on anything as far as i know i use it on all my rc planes boats cars

[MAMBA2200]

well if anyone can help me out on this took the revolt out yesterday and run it first on 4s with the m545 and i got 42mph then i tried it on 5s now i have changed to the 180a esc also gave it a run and on 5s i got a whopping 41.7 so whats the deal i have a tacon 2 pole motor 3674 1900kv which i paid 36 dollars for brand new in a similar boat and in the revolt its a leopard 3674 4 pole 1900kv which i paid over 80 bucks for new and to be honest the tacon is 10mph faster than this leopard or have i just got a bum motor do i need higher timing on the leopard its at 11.25 on the tacon im at 7 so far im just not impressed with this leopard motor at all but its the first one ive owned if anyone could help with this because with all i have read on this forum my setup on 5s should be haulin and its not i am uploading video that i will post today so you can see the boat in the water and by the way the amp draw on 5s with the m545 was only 83 amps it is a short video cause i was bringing it in to check temps

[dana]

That prop is way to big

[MAMBA2200]

it can be used on stock stuff and is good for high 40's is the stock motor more powerful than the leopard??????

[MAMBA2200]

would i be better off with a 4074 motor??

[dana]

To give you an idea, I run a leopard 3674 1700kv in my Titan 29 mono hull, with seaking 120 on 5s2p and x444 prop, and my speeds are right at 50. You should be way faster than me by comparison. The leopard motor is much better than the tacon. Something is not right with your setup. Not sure. Let's hear exactly what you're running. Radio batteries etc...

[dana]

Btw, you're leopard is a d wind. Timing should be 0-5 degrees tops
