OSE 700SC Super on 20 Cell

[fragglez]

Hi all can anyone see any issues with this? I've ran the boat well on 16 Cell with no overheating issues everything stayed cool, I've just ordered two 10 Cell packs which is probably a ridiculous idea but can anyone see any issues I might get?

• 30inch Mono Hull (NQD 757 HighWind Hull! Don't laugh!)
• OSE 700SC Super Motor Can and Brush Cooled
• Graupner Power MOS 60 Operating voltage range 8.4-36V Max. load 60A Max. motor current (stall current) 100 A/10s
• 2 x 12v 3700mah = 20 Cell Battery
• Propeller Ø 42 mm Pitch 67mm (1.6mm Prop)
• Trim Tabs

Cheers!!

please take a video of this ! haha

I used to run 15-16 cells quite a lot when I was messing with 700 boats, 20 does sound fun!

20 cells will probably destroy it.

20 cells will probably destroy it.

Thus my request for a video haha

[greenblast]

does this boat have flames painted on it lol.

[fragglez]

I'll be recording it in full HD!! lol

What do you mean by destroy it? you got me worried now!! the 700sc is way more efficient than the 700 graupner I had previously.. motor cooked on that one... but this one stayed cold on 16cell... whats an extra 4 cell going to do eh?? haha

Short runs man... short runs.

The 700sc is a better motor than the Graupner 700bb, but at 20 cells, the heat will build up quick, once it builds up enough the coating on the wires will burn off and than the resistance will go much higher and make the motor useless.

With that much voltage the internal fan will most likely melt and the motor probably fry a few seconds later. Keep the runs very short if you want any life from the motor.

Will just try it on short bursts or not bush it too hard, just hope it will go fast enough I'm going to be racing another NQD Highwind with some kind of brushless setup connected to a 18V Drill Battery.

Any guesses on speed?

This is me boat a while ago on 16cell :) nothing got hot at all was shocked... will approach 20Cell with caution.

[Steven Vaccaro]

Which 42mm x 1.6 prop are you using?

[fragglez]

A Graupner plastic one

[Steven Vaccaro]

Which model number? Maybe the 2327.42? If so I would try a 2317.45 with the 16 cells. i find on mono style hulls that the 2327 props are not efficient.

[fragglez]

Hey yea sorry, I'm using a G2327.42
hmm you got me thinking, will check when I get home if I've got a 2317.45, I did buy a few props a while back.

Cheers for the tip Steven

Do you guys think this thing will go 30mph ish with what I'm doing?

[Steven Vaccaro]

On 16 cells and a 2317.42 or 45, the Cen Racing Grey thunder used to run in the 30 range.
