Any help/info on getting it faster would be great. Thanks.

hi and welcome to the forums, sorry to say it but me think's you have wasted your money on this.
there are a few things thart you could do to make it go faster
1 put a 8.4 nm hi batterie in
2 you could go brushless but you will need to change the speed controler too
the other you could do is save up some money and build a kit your self which then would be more spares on the market and more reliable too
regards phil

Ohhhhh. Speed controller? What is onvolved in getting this changed, is it major work? If you go on you tube and type in fruits rc boat, that is the stealth with brushless motors and two 13.2V batteries. Its a flier and I would love to get mine as quick as that but don't know what motors to get etc.

you could stick a lithium polymer (lipo) battery but the ESC needs to be lipo capable plus the relevent charger for the battery
OR
go brushless
if you go brushless, its no major thing, tell us the lenght of your boat, if its 20" plus then a motor with a diameter of 28mm or 36mm will be fine, kv rating motor for the boat will be 2500kv - 3500kv, then you use a brushless ESC, depending on how fast you want to go depends on the ESC, most people use 60a, 120a or 200a ESC's plus you need to replace the reciever, get a TRANSMITTER package (transmitter, receiver, servo) rudder aswell, it is advisable to buy watercooled motor and ESC, keeps everything cooler, longer runtime then
transmitter types for boats are 27Mhz, 40Mhz or 2.4Ghz (the 2.4 requires no crystals) the last one is better
list of parts
- battery (lipo plus charger)
- motor
- ESC (brushless)
- transmitter/receiver package
-rudder
you can use the exsisting motor mount, prop shaft and prop
the simplest solution is buy a lipo capable ESC and battery, some soldering may be needed

With a range of approx 30 metres its just as well it doesn't go very fast - you get time to keep it within range.
After you have costed the list that Nick has suggested, you might find that adding the cost of a hull designed for RC in the first place is not too big a price step-up compared with the uncertainty of a successful conversion of this one.
To get any improvement will likely need a complete electronic and mechanical transplant. Most toy makers opt for non-standard ways of cutting costs to keep the price down. This never results in performance that matches the artwork on the box.

If you know the speed (kv) or number of windings of the stock motors, you could get faster (lower number of windings) brushed motors but you still won't know if the esc/receiver will handle the amps required until you try it. Another fella on Youtube has tried 9.6v batteries (8c) with the stock radio with success - but it didn't appear to go very much faster. I'd like to see someone get these to go faster cheaply. If you try it and it fries the radio, I've still got the (new - never used) guts & radio to the Viper here somewhere and you're welcome to it. Just post your build and lots of pics! Sdg.
