Strong launcher set up (storm launcher upgraded to brushless)

I'm trying to decide what to order for this. I'm planning on ordering the motors from here:
http://www.strongrcmotors.com/Motors.htm

but not sure weather to get the 2500's or the 2900's. I would like it to pull vertical (something my stock SL is lacking), and have decent flight time. So what have you guys done? This is I would like to know your setups...

battery used (also the weight)
motors used
props
flight time
does it pull vertical?

also I plan on running on water to, what did you guys do to water proof things? which parts need air flow?

Thanks

>here< is c/f thread on his upgrade. He used the 2500's but he has to use 3S packs. You will have to read through to see his reasons.

I personally like the 2900's. Cause you can fly 2S, which is like stock power, but longer flight times , Or 3S which gives ballistic power, which is what I like.

Fact, My home made motors from Strong RC Are about 3200 kv and the SL flys like a rocket on 3S!

Props used are basically what Strong RC list on his web site.

Any of the 3S battery options are going to pull vertical.

Flight times will highly depend on the battery you chose, final weight , and the way you fly it.

Corrosion X is the best thing to use for water proofing.

Air flow is not to much of a concern with the speed controls because you are not even close to using the capacity that they are capable of handling.

arn't the stock bateries 2S? could you use those with the 2900's? (likely with shorter flight times)

I was just worried about drawing to many amps from the smaller batteries. like this one:
http://www.bphobbies.com/view.asp?id...8&pid=A3467968
lists "For 9A Continuous, 12A Peak Discharge" and the strong motors page lists "2900 Kv motor, GWS 4x2.5 prop, 10.5 V, 6.3 A" So is that 6.3 amps each or total? Is that going to pul to much from the battery? (I'm new to lipo's and don't want to melt it.)

That would be 6.3 amps each , so 12.6 total. Those battery's won't really cut it.

The stock battery's are 740 mah 2S, but they can handle up to 14amps continuous. You can use those with the 2900's with a 4x4 prop. the flight should be close to stock power with slightly more flight time.

Some of the better battery's to use that work well are the Dualsky 730 mAh 11.1V 20C . With that battery and the 4x2.5 props , you will have a great setup with plenty of vertical power.
