Prop for Smash Shark and Leopard 4074 2200kv?

[rol243]

you could take some diameter off the 440 x 3 blade to bring it to around the 435 mark ; 40 mm down to 35 mm. as previously mentioned the 440 x 3 blade is a better prop for faster turns but in the straights it will eat up battery power , this could be why your wires are getting hot. if you want to try a 2 blade try something like a 447 and you can cut it down to a 445 size than maybe a 442 size ,if needed. to find the right prop you need to play with them.

The wires are getting hot because those deans are getting hot.
A 35mm prop is too small for a boat this size.

I agree the dean's are probably not a good idea I would run at least a 5.5mm bullet.

Take the tongue off. The tongue helps the boat get out of the hole from a dead stop but also helps torque the boat over and acts like a governor for speed. We don't need tongues any more with the amount of power we have. If your wires are getting hot then the deans plug is too small or you're running your boat to long.

Alrighty.. the wires were hot on the first boat with the 440/3 and trim tabs installed, it ran much wetter and slower with the tabs mounted ~1mm up and flat/parallel with the bottom.

On the second boat/rebuild I left the tabs off and only installed the much larger ose rudder (which works great and fits perfectly btw)
Its definitely faster, runs longer and it comes back warm but not super hot.. the trade off is its also pretty rowdy at speed (chine walk) without the tabs.
Next I'll try getting some weight in the nose instead of adding drag to the back.

Aside from that this hull seems naturally ill suited for pure speed (like the Outerlimits) or speed and good turning (like the Pursuit).

Perhaps its a better rough water all-purpose fun boat... so with that in mind I'm going to try a slow speed big wave setup to run alongside our full-size boats.
~20-25mph on 2s (2x 2s 5000's in parallel for really long run times)
Nearly zero cavitation out of the hole, looking for really good throttle response/hookup at slow speed.
What would be a good prop for that? Maybe something like a full-tongued x452/3 or 455/3?

I realize it will torque roll more, but not really worried too much about it due to going slow'ish, so long as it doesn't just lay over on it side and stay there.

If you have split tabs like the Pursuit, set the outer tabs lower. That will lift the rear in a turn, pressing the nose in a little for more bite. Give the strut more angle if it runs wet with tabs installed. My Pursuit has the tabs all the way up with a decent angle added to the stinger. My tabs came bent with 1-2 degrees which puts their tips ~1mm below the hull edge, but I've considered bending them flat.

From what I've read, the Pursuit runs circles around the SS and OL hulls. Your hull is 20mm longer but 20mm narrower, which will make it less stable at speed...but potentially faster if that 20mm adds to the lower transom. The Pursuit is down to $160 atm, I'm almost considering a 2nd. It uses all the same internal parts and the stinger is 78mm, so you may be able to swap all the parts if you change hulls.

I also would be careful if your "big wave" setup intends to actually create a large wake by not getting fully on-plane. Planing hulls like this require a lot more power before they get on-plane. Buzzing around at half throttle with a few full throttle stabs will use less juice than constant start/stop.
