Hi Jabbran,

Both boats are made in China and are sold by shops all over the world, the shops have to make a profit too, so the boats will be a bit more expensive, getting one directly in China is cheaper, but you don't have support from sellers, like you would have from Astec.

The monohull Is capable of 85 km/h (50 m/ph+), (depending on the battery selected, stock, on 3S it will do about 25-30 mp/h.
Runtime with say 5000mAh Lipo; 8-12 minutes full throttle, depending on set-up and drivestyle.

The Apartition Cat has a larger hull and can be made to run at least as quick as the monohull (50 mp/h), stock it will be as fast as the monohull.

On both boats there are large threads on this and other forums, do a search and you'll be reading for day's...

To make both hulls ready for the water you'll additionally need:
- transmitter/receiver set
- servo
- battery
- charger + power supply
- 4mm goldplated connectors, as most Lipo's come without
- electric tape to tape shut the hatch

Let me know when you've selected a boat, than I can get more specific and provide links.

There are a number of suitable hull in this price segment, I gave you the Arowana, you may want to dig some more yourself.

Sure, if your battery is empty (or the low voltage cut of on the ESC steps into action) you can replace the battry with a fully charger one.
Do check the temperature of the motor and ESC, as prolonged runs can cause a heat build up, if so, allow the components to cool down to ambient temperature before starting another run.

The transmitter in the link is the cheapest 2,4GHz available, read the buyers comments and get an idea of the quality offered for yourself.
I have one shipped to me, it hasn't arrived yet, so I can't tell you if it not only looks cheap, but feels cheap too...

Regards, Jan.
