After many points adjustment i.e. prop line, use 3S 1000mAh, the boat run faster than 2200 mAh, etc. the last point to be corrected is to balance the boat to prevent turn over in hi speed.

need to modify (correct the props line) to avoid diving while hi speed, 3S 2200 is not a good idea cause it too heavy for prop to lift boat. I will chang a larger prop and reducee the Size of batt.

Just got it yesterday and it's more than expected, some minor things like you see in the video need to be done to get it running nice.

Major plroblem is just that my hands are to big to get in to it :-D

Now I have to get it on the water to see it running !

I have been running this little guy for about a month now and I tell you once it is diald in it is a great little boat. I run it on a 2200 mah 2 cell and it zips allong pretty good with a 4 foot rooster tail behind it! I think I will need to change the speed controll soon because the one included is a little finicky and Im not a big fan of it, but it works decent. you might want to find a new way of keeping my hatch down tho because once you peel the tape off after a few times it peels the clear coat finish off of the boat. Goes for about 20 minutes at full throttle with a 2200 mah.

I will post a review video soon.

Problems with balance, torque roll, and don't like surface prop
design. Buy a small bolt hydro from HK, you will be much
happier, they run and handle great on a 3 cell.

Received boat, put 2 two cell packs in and after 2 minutes flames came out of the boat due to the poor esc soldering internally. replied to hobbyking about the bad esc which ruined my day with friends and also stated that i have pictures of the burned esc and there reply was for me to ship the item back as if it was my fault the connections were bad after 2 minutes.

My rudder fell off and now I can't use my boat anymore. "*Spare parts arriving soon" they say. When I wrote to ask if they could supply me a new one I was told the boat manufacturer didn't supply any spare parts for this boat. I would normally recommend anyone to buy this great boat, but not as long as they doesn't supply any spareparts. Anyone know where to find a rudder which fits ?

Today this boat had it's maiden voyage (test run)

which ended in disaster - it sank.



What can I use (material) to balance the boat only if it has 1 battery to power it ??
