I am looking for a good setup Deltaforce 33 " cyberstorm.

[SSchevy98]

Do you have experience lehner 1950/9 1393 kv motor in a boat 6 or 8 s voltage?

40 mm motor mounts ?

Max amps? Maximum voltage at?

Props: octura x440/3, m445/2, x450/3 and x452/3 good size ?

I am using this esc : TMM 25035-3x series.

Hey,
I know some other senior member will help you with some good info for the build.
That look like a good esc, But I never ran or seen one before.
I did a search in the builds post and hears some reading info that may help.

[nata2run]

I'm replying because I got got a PM on this subject so I thought I'd share the recommendation with you guys incase I'm way off, you can correct me. I can only speak good about Lehner and have had a few of them already. the 1950/5 is a good size motor and 2 of them can take a 44" cat way past 100mph. I would guess this is a good size for a 33" mono and the MGM ESC is good for 250A and 300A ish on a burst. Since Lehner handle RPM well I see no issue in running a 445 on 6s for around 60mph and later on move up to 8s with a 440 for more serious speed. If this is suppose to be a progress "where you don't burn stuff" then ofcause start slow with smaller props and short passes (1-2-3) then measure temps on everything!! motor, ESC, Lipos then move up a prop size.... I have a feeling the 450++ props may not suit safely. Also consider the 1393 kv is under load! (so 1600kv ish or just under in normal terms) Again, just my thoughts. This is how I would aproach it if it was me.

[lenny]

Good morning,:tiphat:

Anybody know what the Delta Force 33" cyber storm hull can handle as far as speeds ?

Also what can size of motor will it take with out having torque roll from it and the prop,

And is the Pursuit hull just about the same as the DF 33 hull and will it handle the same speeds ?


Thanks for any info on the hulls.

[SSchevy98]

I think I'll end up with this motor lehner Hiamp 2250/9 1315 kv , 2x 4s 6600 70 C thunderpower pro force batteries series ?

Is that a good choice?

Do you know where in that should a suitable motor mount? Or do I have to carry out one?

Does anyone have experience with this store ?

http://www.rc-raceboats.de/shop/lng/en/lmt-motorserie-2250.html

Send a packet to Finland?

[nata2run]

Seem ok for the motor, I would get the LK though then run on 6 and 8s. That motor should pull some bigger props as well. Again start small!!!! I many times thought of doing a 2250 in a DF. You can buy from lehner direct. Maybe get the motor with 6 outputs just to give you a couple more options. You can use lehner motor mounts for front and back and mount to a carbon plate.

[kevinpratt823]

My Cyberstorm has a Leo 1600kv on 6s. A M545 gets it moving up around 60, but it gets a bit sketchy if there's just a little bit of chop, so I end up at partial throttle a lot, which causes more heat on the esc. A M445 with some cup in the tips gets me up to 55 and I can run it wide open more and makes it more driveable. A m447(or maybe it was an x447) didn't seem to give me any more speed, but bigger props get it walking a bit.

[SSchevy98]

thank you guys for this :buttrock: I do not yet subscribed to the new lehner 2250/9 motor.



I'll try leopard 4082 1250 kv motor first :biggrin:

[madmikepags]

Yeah bad choice for a reallly fast boat, mine is the current national champ in P-Mono and its very fast on 4S with a NEU 1521/1.5d, and prather 235-250 props (depending on sprint or offshore classes) i can get well ino the 70's but the boat has bad tendencies at those speeds, especially in chop and race water, Mine is definitely on the heavy side because it is a race boat. 60-65mph is about the top for racing or any chop, but i've seen em go well into the 80's in a straight line. I think 6-8s might be overkill w/ this boat.

[SSchevy98]

Why I could not run leopard 4082 1250 kv 8s lipo ?

Props. Octura m445/2, x440/3 , x450/3 and x452/3.

Are those propellers the right size?

the only prop I would try with 37,000rpms is the 440
37,000rpms is a bit much if you want the things to last
a 1000kv motor for 8s use would be a better choice
the 1250kv motor would work better on 6s

[madmikepags]

37,000 isn't crazy but if you are gonna run it on a mono make sure you use a wet well or cool the stuffing tube inside the boat, at those RPMs, the tube and thaft get very hot and the brass tube will melt.

[madmikepags]

Hey SSchevy , while the Lehner motors are very high quality units I personally have found that you can get better efficiency from other brands at cheaper prices, I don't know if you're here in the states but Neu's Leopards and others are much cheaper here in the states.

[lenny]

HK has some good cheap motors,:tiphat:
PM for you mike on motors for a pursuit.

I did not want to get off of the info you where looking for,
So I sent a pm to Mike for some input on my pursuit and setup for it.

I have a pursuit mono and running a 4074 1800kv in it,
And I was asking Mike for some info on a better motor setup.
Because I have a lot of motors setting around to try in it,
Now that I see how the boat runs and handles I think it's time to up grade a little.

[lenny]

My buddy is using one of these motors in a geico on 6s with a 130a hv seaking esc,
Runs nice and cool and lots of power and head room for the amps to.
http://www.hobbyking.com/hobbyking/store/__17720__XK3674_B_1400KV_Brushless_Inrunner.html

May be one of these motors would get things rolling for you,
To test and see how the setup work in that hull.

I have already leopard 4082 1250 kv motor :biggrin:

[lenny]

I think you would be push the limits of the motor on 6s,

22.2 * 1600 = 35520 rpm unloaded.

You need to make a choice to run on 6s or 8s than we can help find a motor for you.


Lenny.

What do you think TP power 4092 1600 kv motor + 6-8s lipo ?

[lenny]

Well on 8s that would pushing it some at 1250 *29.6 = 37000 rpm unloaded.
But 6s and 7s would be good, 1250*22.2=27750 rpm and 1250*25.9=32375 rpm.
That is a lot of motor for that hull.

[SSchevy98]

It is then seen how that works.

Are those TP pro force 4s 6600 70C batteries too heavy delta force 33 cyberstorm?

CChevy
I have been running the TP Power 4092 1600KV motor on 6S and have not had any problems with heat and such.
I run a 445 or 447 using surface drive (stinger) depending on what I want to race with.
It is a delta wind so run the timing around 3-5 deg. max.'

Update,

the boat is almost ready to glue the motor mount to keep the boat and onto the drill with a few holes and has found a place in the batteries :laugh:

Ok, :tiphat:
So what is going on ?
You have the boat setup and it is in the water and you are doing so prop testing with a x446/3, Yes ?
Can you post some video's of the boat running ?
And can post some pictures of the boats hardware setup for running and the setup in the hull to ?

[SSchevy98]

Hi Lenny,

I'll post a video and pictures when I have time,the boat is still a bit to adjust.

[SSchevy98]

The speed control temperatures of 33 ° C and motor temperatures of 31 ° C .

X446 / 3 prop maximum 138.9 amps and the power of 4200 watts.

[lenny]

Ok,
What boat are you talking about that was leaking ?

I am not sure what you are asking me or till me with this,

Is the boat staying dry now ? What size of silicone hose you will get 8 mm propeller shaft tube on top of the water-tight?

i use 8x4 mm silicone hose, and I do not get it in any of 8 mm on the tube?

[SSchevy98]

Hi Lenny,

No water in the boat any more than a few drops.

What do you think ?

[lenny]

:tiphat:

Well it all looks pretty good,

But that is a lot of wire in their and I think it should be shortened up.

The more wire their is the more resistance and heat build up at Cells, Esc , Motor, and Connectors,

But you say all temps are just about at 90*f and that is very good.

But how long did it run to get to those temps ?

How much run time do you get out of those 4s 70c 6600 mah packs and what are the end run temps on that setup ?

Also why is the water tube so long that is on the port side exit ?

Was that for testing for leaks in the setup ?

[lenny]

The jacket is nice but the nipples suck,
They have a very small ID to them.
I would use some other nipples like the one's on the leopard jacket or bigger.

[SSchevy98]

Lenny,


Are they better?

http://www.offshoreelectrics.com/proddetail.php?prod=etti-a029

Why the need to change a better place?

[tlandauer]

Lenny is right, these fittings are on the small side, change them if you can, having said that, I like the machining of HRC jacket, the channel that holds the "O" rings are deep and provides a secure hold so there is little chance that the "O" rings will dislodge while the jacket is being installed.
What I do is unscrew the fitting, look into the inner hole on the hex , mark a line across on the outside top of the brass hex with a Sharpie marker where that hole is oriented, put the whole thing back but ALIGN the marking with the nipple. Also don't screw down too tight as the fitting will protrude the underside of the jacket, in extreme cases it will touch the motor can and reduce water flow to near zero, don't ask how i know... :frusty::lol:
