Does a higher kv motor mean more top end?

No. It's a mix of kv/cell count/ prop choice.

Refresh my memory. Exactly what are you running?

Hey rude have you tried pushing your batteries way forward to an exaggerated point to see the effects. On mine I put the batteries 3 inch forward of the motor and the thing wouldn't get on plane. I pulled it back run by run until at full throttle it wanted to pack too much air and flip then I went back forward a little. That was on 4s 40 mm stock prop. The result is a boat that I can drive in light chop or light wind because it launches off waves level. A well balanced boat should always fly level in my opinion. The second problem I had was the strut adjustment I moved it up like everyone here is recommending to about 1/4" above the bottom of the boat. My stock prop had about 1/16" clearance. Out of curiosity I notched the aluminum and put a x447. On 5s with pure stock 1800 kv motor and 80 amp esc it ran 44.3 GPS. The motor was warm but not hot with several short 30 sec passes. If the water temp was hotter it would not have worked that well. I do believe with a different prop I can see 50 with stock setup 5s. Speeds beyond this would require bigger esc and different prop. You have the right equipment to see more speed just play with the balance so that you can run full throttle and not worry about flipping the boat.

I did 85.5 KPH today. Thats what gps said. Im gonna past that. I found that I put the batteries too foward which cause bounce . I was unable to keep it open, but got 85.5kph = 55mph

Few weeks more and ill finish my Zonda. I cant wait to let it RIP.

I have a MG that has been to 70mph without going over, 72mph with blow over. For me, CG and prop are where the results come from. Still more in the boat, but I have not tried any more cause when you crash at that speed it tends to tare up the boat.

[rude5150]

What set up gave you 70mph in MG?

[rude5150]

Whats your battery position?

I was using a NEU 1515 / 2200KV. 2 3S 4500 cells in series, so 6S. I ran the cells as far to the rear as possible. V942 prop. The 3 blade prop makes a huge difference, it seems to keep the nose down. I have a ICE 240 ESc, and its pretty big, so I ran it on the left side next to the motor. http://youtu.be/4PG9dqwECFQ

So what happened to the hull, any severe damage? That is no small feat you accomplished by cramming that ESC into the hull!
While I admire your speed, I must say blow over like this gives me nothing but grief. I know everyone has a different take on this, but just seeing your boat crashing made me cringe! lol...

[rude5150]

Thanks. That NEU motor can spin higher rpm's than what most guys are running out there. Im working on my geico 24 now.
Any one know where I can buy a cheetah boat?

Well, after the above crash, you can even hear it bounce up on to the dirt, nothing happened, I set it back in the water and kept going. This boat has crashed countless times over 55+ mph and I still drive it today. The off-set rudder bracket is not very sturdy, so I have bent a few of those, usually just bending it back into position.
