Manny, when you say "improve stability", can you describe?? I might have some tips that would help... I know a few tricks for this boat that I haven't shared... yet...

I have found that getting the weight too far forward causes issues... I've had better luck with having the weight at the CG, and then using the tabs to get the nose down. Keeps the ride back at the keel where it belongs...

A tip to ALL of you... Replace the turn fins with some squared/rectangular fins... For starters, you may just take a set like the Revolt's and modify them to fit. They don't have to be very long... My fins for the P-Ltd setup are about 1/4" above the keel when viewed from the back. Make sure they mount RIGHT up against the transom, and extend down at just a slight angle. Make them about 1.25" or so in chord. You will be AMAZED at the stability you'll suddenly realize, especially in the corners...

I sent a pattern to Steven and I believe that OSE may be working to produce/supply them for you. Future offerings from Pro Boat will also have this design. It's a "design flaw" that I put into this boat, and the one real "mistake" I think I made when developing it. The straight fins make the boat much, MUCH more drivable in the turns, especially when it gets rough. Try it!!

Tried a motor and esc swap....leopard 4082 2000kv 180amp esc....on 6S with stock prop ...at 2/3 throttle its running way to dry. Definately a lower KV for 6S is needed, my buddy never could open it up, it was uncontrollable...I dont think a prop change would help at all either....DJ

custom rc boat propellers (more speed)

[olwarbirds]

Manny, are you using a ball bearing to get your cup even ? ...Ive got so much to learn about props yet !!! ... DJ

[formulafastech]

Would a Prather 220 be a good prop for the impulse or a octura x440 fit I have these props already that's why I am asking I plan to use 4s 5s and maybe 6s if these props are no good can you tell me a good prop to use

[formulafastech]

Today while I was out driving my impulse I had no heat problems but other problems I was using 6s and it flipped the hatch came and the hatch seal came off to and I lost it cause it sank then the boat is supposed to be waterproof but my servo twitches now and my hatch has a crack I was mad when I lost the hatch seal and the servo twitches but other than that it ran fine but I was running in cool water too
