Scorp, your pm box is full. Originally you suggested the x245 prop with that 1000kv motor. After we do the swap..i will need to change that prop to a x460? Also, can you tell me what the hole spacing is..im anxious to put an order at OSE...last thing..for now..the turning fin..you made your own...does OSE have something similar? Thanks

Most of the guys I've seen use Futaba. None of the RTR boats come with marine equipment, most are ground receivers in a water tight compartment. About the only thing you don't want to use are the smaller park fly receivers due to the limited range. And if you look at what Futaba offers they separate by air and surface with surface being more wheeled controllers with 2-4 channels. Now again I'm only talking 2.4ghz.

"IF" the Turnigy is a copy of a Leopard it will be a 30 mm hole spacing with 6 bolt holes. You should be able to check the one you have since they are the same except for kv rating.
Unless I'm mistaken scorp was running a cut down S270 on his big hydro, but it's being pushed by a Castle 2028 too. I'd suggest starting around a 452 or 455.

I just PM'd you Stiks................... and i suggested basically the same props that Bill did before i saw his post.................we outta be close then. The Turnigy motor is about 75-80% as powerful as the 2028 is, so it cant turn quite as much prop...............

I dont know if OSE.........or anyone for that matter, sells a turnfin the size of my custom made one. You need a pretty beefy fin in my opinion. Mine probably cost about 50 cents in raw aluminum stock.

FOR CONTINUITY; this was question scorp answered regarding the shaft and motor connection..

*scorp hope you dont mind...

You wont be able to use the stock strut, its for a 5mm shaft. I had to buy a new strut from OSE and put it on..........i'd strongly suggest 1/4" driveline sytem. You can buy a flexshaft that reduces to 3/16" on the propshaft to use the prop sizes you will need...............i'd suggest somewhere in the x455-x457 range for 10s and x452-x455 for 9s.

Here come the newbie questions:

So the drive line is the "stiff" piece see below:

then the flex shaft is something different or are these one in the same?...starting out as 1/4 then changing to 3/16

It's all the same. The dark part of the photo on the left side is part of the flex cable. The shiny part on the right is the "stub shaft" which is 1/4" and then stepped down to 3/16".

Also on props, the 455 to 457 would probably be for 9s and the 452 to 455 for 10s.

Yep, wrote it back wards:

Hey Mozz, this is the new rage of whats called a "Faux build", you think it all up in your mind to see if it would all work, calculate the prices, then enjoy watching it run in your mind.............................

Whoa..Whoa..just trying to get my ducks in a row.. Take it easy..the pics will come...Mozzy..or would you rather i buy a bunch of stuff then start asking a bunch a questions..

The boat should be here today or tomorrow. The motor and esc have been ordered and are coming?? (from hobbyking). The servos will be in tomorrow. With that said..Bill do i need to purchase another part for that drive "rod" or is that it? I thought there was some type of coupler from the motor shaft to the drive

You will need a drive coupler. Not sure of the Turnigy motor shaft size but guessing it will be 8mm? So you'd need one of these from OSE as well
