sv 27 motor

[txboatpilot]

You can run the Ammo 2600 with a smaller prop than the m445 I run. Just run very small prop to start with, watch your temps and go up in prop size to gain more speed. Start with something like a CF40 and go from there.. Just watch the HEAT!!!

[txboatpilot]

What motor are you running now?

[SweetAccord]

RcPrince is running a 2600, so the hull is capable. Is this the limit?

[txboatpilot]

Capable, YES.. Limit YES..

[SweetAccord]

I have the stock SV motor, the AMMO 2300 and the 2600 on order. Steven claims that the Feiago's, my impression by him, are faster?? The XL in particular, stating that the XL has more torque than the L. So what is the advantage and disadvantage between the two of the same KV?

[txboatpilot]

If you want a 60+MPH motor look at a 1515/1.5D (2700KV).. Run that with a M645 and you will take FLIGHT!!

[txboatpilot]

The XL with the same KV can spin a bigger prop with less heat..

[SweetAccord]

Ok now we are talking.....

[SweetAccord]

So the XL will be faster pound for pound over the L with the same KV with less heat? What about run time? Shorter? Which KV is the ideal one? The 8XL?

[txboatpilot]

What speed have you got out of the stock motor? What props do you have?

[txboatpilot]

Run time will be shorter(not much), the xl will take more mAh from the batteries.

[txboatpilot]

Ok now we are talking.....

Sometimes this stuff is hard to get a hold on! I will try to explain the best I can..

[SweetAccord]

I don't have a GPS or aything to be honest for accurate speed values. Did you see the YouTube post I did? That is a bit faster than mine. I have 440/3, 40x53,40x52/3, CF45, CF48, CF40.

[txboatpilot]

The thing you need to look into is lipo's that will increase your speed more than anything..

[SweetAccord]

Ok I want to be able to drag race basically. I just want to run the limit of this hull design. I have the Hydra 120 and will be running 4600 NIMH's. I can run any prop really that is recommended.

All I would really like to know what is the motor that will make this hull design scream, but still make it runnable? Any ideas? I have the 2300, the 2600 AMMO. Steven stated the Feiago's are fast if not faster is the impression I'm getting.

So my posing question, maybe you can't answer, what will be the better motor, a L or XL. Steven says the XL. Another person says the L. What is the advantage and disadvantage of each in the same KV rating?

Also which would be the optimal motor KV to select that will allow a high prop. run fast and not heat everything up and allow me to tune it down, if need be?

I just don't want to get a motor that is useless and non runnable with any prop that I can fit on the 3/16 shaft and then have to sell the motor off. I wish to get the advise that is right on.

See where I'm coming from? Once again maybe you can't answer me, but I'm putting my question forward.

I'm willing to want for now to get the most out of NIMH, Lipos down the road.

Thank you, I really appreciate you helping me on this!

[txboatpilot]

If you want to drag race you are wasting time with your HEAVY batteries!!!Drag racing is about "KEEPING IT LIGHT"!! Lipos will give you a 4-6mph increase with any prop or motor!!!

The 2600 will make your SV SCREEM!!

Now that I know what you have and want to do, we will get you set!

Start with your 40x53 and then go up to the CF45 and CF48..

[SweetAccord]

WOW thank you, so of these Fieago's:

540 6XL 2,779 RPM / Volt
540 7XL 2,382 RPM / Volt
540 8XL 2,084 RPM / Volt
540 9XL 1,853 RPM / V olt


Which would you get? I want one more to spare/different motor.

Thank you kindly!!

[txboatpilot]

I run a Rigger with the 1515/1.5D (2700KV) and X640 on 4S1P lipo and get over 60mph easy in a straight line..

[txboatpilot]

Try the 7XL.. It will fly on 4S lipo...

[SweetAccord]

I won't be using Lipo, will that be an issue?

[txboatpilot]

Only issue will be knowing that there is more SPEED and you cant get too it!!!! LOL

[txboatpilot]

Do you have a extra 2300 Ammo, I need another for a twin set-up I am working on?

[SweetAccord]

I only have the one 2300. Sorry.

Hehhee....I have EP4600 which are Trinity EastPowers. They are pretty high rated. So the SV can run a 540 7L 3,511 RPM / Volt 5mm Shaft
with a Hydra 120 ESC (120AMP) with no issues? Unless I go prop crazy maybe like the CF48? Any run time estimates?

[txboatpilot]

You should be happy, just watch the props! Run time is hard to est. With all these motors you have bought, you should really look into lipos! They are night and day from NMHI... Read the last issue of boat modeler mag. Jay Turner has a great article on the diff. in lipo power vs. nmhi......

[txboatpilot]

Metal props dont flex like CF props, so you might stick with the 40x53..

[SweetAccord]

Wonderful. I was under the impression that the 2600kv was the running limit for a SV motor in that hull. Now that I know a 7L 3,511 RPM will work too, sweet!

I just got all the batts and chargers, so down the road I will, i figure the batteries can be the last push, once I make it run as fast as possible on NIMH's the Lipo's will be the nitrous!

Do you know someone that runs that 7L 3,511 RPM in a SV?

[txboatpilot]

That is 7XL not 7L!!!!!

[SweetAccord]

Oops you right, sorry, I meant the 7XL. So the 7XL 2,382 RPM / Volt is the one. Is this one slower than the AMMO 2600 due to the Kv rating or is the XL cause of the length and torque compensating for that?

[txboatpilot]

If you are going to run in a straight line, remove the turn fin! It causes drag, and will free up 1-2mph..

[SweetAccord]

Remove turn fin.....writing that one down. Man this is gold, anything more?? I'm eating this all up!! You great!!

So is the 7XL slower than the AMMO 2600 due to the Kv rating or is the XL cause of the length and torque compensating for that?
