**Guys** help me build a boat DF Cyber Storm 33

[pyroM!KE]

Im going 6s 2p..What size batts should I use..I want the biggest I can run but I dont know what the max weight and dimension speks would be..Im thinking 3000-4000mah in parallel totaling 6000-8000 mah..

[bill34207]

Determined to do it ain't ya? I'm really at a loss for any cut n dried advice in this one. That's a really small hull to try to pack 6s 2p into. I got a feeling you are going to kill your "reliable" factor along the way as well. Still, if you are determined to do it I'd suggest waiting til you get the hull. You can always cut up some styrofoam chunks to duplicate pack sizes and see what can be fitted inside along with your motor and esc.

Some things to consider as I try to talk you out of it. If you decided you wanted to race it, you would be stuck running in Q class and against boats with a hull length of up to 40". Which do you think would fare better in race chop?
With 6s you are peaking out both your esc and motor. From what I have seen (in person and some threads on RCG) the Lep 4082 doesn't really like being "peaked". You don't have to take my word for this one, ask RayR what happens when you load one with what it's rated for. Buzz it at high rpm in a race scenario and you'll most likely throw a magnet like he did. On 4s I think your motor will live considerably longer and you should still get your low to mid 50's that you want after you get it propped right.

[pyroM!KE]

Hmm..ya got me thinking hard now.. :)
I want this boat to ultimately do 55 reliably..I will sacrifice some handling for speed and battery capacity..I dont plan on racing..Just bashing..Could I get close to that on 4s? Mabey 5s?

[bill34207]

I'll say that my DF33 runs in the 50's on 4s 2p with the X450/3 prop. It's never been GPS'd to back that up (not really enough room to put a GPS in it) but an educated guess. And it's reliable as it doesn't pull a lot of amps with the setup that's in it. It's also competitive in the P mono class. 4s 2p would be a low stress setup for your Leopard at it's kv rating so it should live a longer life there. My Neu is a 1577 kv your Lep is a 1550 kv. They are really close in the kv range.

Something like the DF35 would be a better choice for a 6s hull. But you'd really need a different motor as well if you want to keep the reliability factor. You might get away with running the Lep on 5s but 6 would be really pushing your luck. Something like a Neu 1527/1y would be my choice for a 6s Q boat. I like reliable. If I don't finish a heat I want it to be because my boat is floating upside down, not because it's been filled with magic smoke.

I agree with bill34207 , I run a pursuit 33" hull with a lep 4074 2000kv with an x642 it goes like HE** but the batt. packs come back at 135 to 140 deg. F with a M445 it's still a fast boat but the packs come back 110 to 115 F this is on 4s1p 5000 pack . This is just my opinion ,if your going to run it on the ragged edge it's going to cost you in ruined packs,motors,and ESC's . One more thing I hope you ordered ride plates . You'll have fun buliding it and a blast running it .

[pyroM!KE]

The more I think about it and listening to you guys info I know what its gonna take to build one..But I think I may consider a 35 inch hull. Ride plates? Are you talking about trim tabs or plates for the batts?

Why wouldnt the 4082 be enough for the 35 DF....If I get the 35 df ill get the 1450 kv and run it on 6s.. That would be a good setup wouldnt it?

[bill34207]

Ah, so you're not yet committed on the motor. The 1450 will probably live on 6s operation but keep in mind it's a D wind and will probably toast your esc if you get the timing a little too high. If you could find a Castle 1717 they make an excellent motor for 6s operation. At 1580 kv it's actually a higher revving motor than the Lep would be but it can handle it. I have 3 of them in use at the moment. Two in my big Expresscraft Thunderbolt cat and another in an Aeromarine Sprintcat .40. Both boats are pretty wicked in the running department.

Coming back to hulls, you might even consider one of the Promise Hobby 39" monos. It would give you a little more room and they do handle well.
scorpion1 (on RC Groups) aka make-a-wake (here on OSE) has one of them. It was his 39" one that caused me to buy the 47" one for myself.

[pyroM!KE]

Just ordered my new boat..I got the DF Cyber Storm..I dont know what it is about that boat but I love it.. Probably gonna try 5s and 6s..I think with the right prop I can get at least 50 reliably..Well see how this goes..Ive seen plenty of 4082 1550 setups on 6s on youtube with reports of great results..What is good about this is if I dont like the 1550kv Ill just throw in a 2000 kv on 4s..Im gonna be another contestant..Looking at 4s 5000 pack dimensions and weights, the 3000 6s packs are pretty darn close (either way ill run 2p setup for more run time)..I will have a crap load of pics going along with this build..
Im so excited about my first build..Im not gonna just throw it together either..This should be a nice build..I pretty much have it in my head exactly how the build will go..Thanks guys!!

[bill34207]

That will work too. I'll still stick around and lend a hand for what I can but you're on your own for squeezing the packs in.

[pyroM!KE]

Ok.. Now all I need is prop and batts..Ill get the batts later..But with the 1550 on 6s which prop is a good one? The x447/3 ?

[bill34207]

Hmmm... I smell something cooking and I don't think it's Thanksgiving dinner.
The 447/3 would be safe on 4s but for 6 you might want to start with a 442 or 642.

[pyroM!KE]

There are guys talking about running x450/3 cut to 47mm..That prop has slightly more pitch even and there saying they have cool temps in there DF 33's on that..I dont know..I wish I could get some first hand experience comments with this setup...

[LarrysDrifter]

I have first hand experience with 2 Cyberstorm hulls. One with a Castle 1520 1600kv and the other with a Leopard 4082 1550kv. Both are run on 6s. The Castle motor is run 6s2p using two 5000mAh packs and two 2650mAh packs for its 2p. The prop is an X447/3. Boat runs great with temps ranging 120-145 depending on water temps.(These temps have been observed during the summer months).
The Leopard Cyberstorm runs 6s1p using two 3s 5000mAh packs in series. This boat uses the same prop and will use the 50mm 3 blade cut down. Temps are in the same range as the Castle hull. One thing to remember on the Cyberstorm is that they like turn fins...from my experience anyway. Nothing against Bill, but the 447/3 will not cook anything. Just make sure to get the ride attitude right and youll be good to go. A good starting prop is an X445.

X445 Is that the 3 blade?

Also do you have any built pics of your Cyber storm?

[LarrysDrifter]

Its a 2 blade. The Castle C.S. Is Suckmywakes, a member here. Look up his profile, then look under his "started threads" and youll see that one. The Leo C.S. I recently finshed building for a friend. Ill have to take pics of it soon to post for you.
