6cell or 8 cell with my set up

[blowNover]

ok, no offense but this thread touches on one of my biggest pet peeves- somebody that asks questions, but "knows" all the answers... Yes- your kv is technically too low, no- a bigger prop will not take longer to plane out- it is the type of prop that caused that, yes- if it does take longer to plane- try dropping your strut to get more bite, yes- even with a low kv motor, a bigger prop will get it out of the hole harder, yes a bigger prop with more pitch will give you more speed- even with that motor. No more, no less. Mike has excellent advice, as do many others here. Don't ask questions then respond to all the answers with "no offense but i work on real boats, i know what i'm talking about" if you did, you wouldn't ask in the first place. We all learn as we go, you have been given some good advice here, take it or leave it.

thank you!!!!!

[kwiktsi]

thank you!!!!!

Anytime :). I'll bet you even one of the CNC aluminum 45-47mm props with the strut dropped until the prop bites will make a big difference with this boat.

I'm sorry guys but some of you are the "know it all" no one besides me has ran the boat. The motor is just not spinning fast enough. When I say I have my own boat that is just to let other people know I'm not completely out of the loop. Do the math the rpms are not there. If you read the full thread you will see the real question is why are my rpm so low. As far as the strut goes every other person with a genesis says put it on a table and have strut flat. That's what it is.

[Engelkefarm]

Blow over tell me what prop to buy if its too big I send the bill to your house.

thats interesting that blownover had the issue with 4092 motor creating too much torque roll, perhaps kv was low and prop was slightly large? In that case I would take his advice on 4082 sized motor instead of mine. Thing is with TP power motors a few members on this forum decided to make quick judgement about their performance and the popularity of motors didn't gain much attention on this forum. I mainly run SAW style boats so spend a lot of time on hpr/mhz forums and a lot of guys have been running the tp 4050 motors of 2350kv and have been having just phenomenal results. They're just extremely powerful and people are making these comments after years of experience with lehner and neu motors. They're just great.

As far as Neu motor goes I wouldn't, the genesis is a $75 dollar hull no offense, the motor is worth quite a few of them. I would save the money. You won't appreciate the difference of this motor over a leopard or tp, these motors on 8s have pushed the genesis to 85 mph. Ya sure the Neu will last longer but if you're like most of us in 6 months or less you'll be looking to try a new setup and different boat. As far as the whole prop dilemma goes if you're into this hobby for any length of time you're going to have a bunch of them. They're 13 bucks each buy a bunch sell off what you don't use props always sell.

OK then explain this for me since I must be doing something wrong.
Proboat 1500kv 3656 motor running 14.4 volts 21600 rpm unloaded.
You have 1050 kv and a bigger motor running 22.2v for 23310 rpm unloaded.
How come I can run a 47mm prop at a lower rpm than your setup with a much smaller motor and only draw 68 amps average and have a competitively fast boat?
Fact is for a given voltage the lower the KV of the motor the higher the torque will be therefore you can turn a bigger prop.
Not saying you setup is ideal BUT you are dead wrong about not being able to run a bigger prop than you are, you could probably run a 50mm prop on that setup and pick up quite a bit of speed IF it's set up right.

[Engelkefarm]

So your best advice to me is to buy a 50 mm prop? Your all out of your mind I think.

[Engelkefarm]

I need a higher kv motor. Big prop on this thing will not be very fun to drive

assuming wont help
the only way to know is to try it

Siberianhusky is correct- you have a little over 1000 more unloaded RPM's than the Miss Geico- which uses the motor he used as an example, and they can run very well with that motor. It is not ideal, not going to be the fastest thing out there, etc. but your boat will run far better with a bigger prop and proper setup. His "advice" is not to get a 50mm prop, he simply stated that "you could PROBABLY run a 50mm prop and pick up quite a bit of speed IF it's set up right".

As for "know it all"- you just said "As far as the strut goes every other person with a genesis says put it on a table and have strut flat"- so, tell me- how is EVERY OTHER PERSON's setup working for *YOU*??? Sure, with the right motor and prop combo, that may be ideal, but every boat and setup is different and YOUR BOAT needs to be tuned for how YOUR BOAT runs best, but then again- you have a real boat, so I'm sure you already know that . Good luck to you, you seem to be doing so well so far ...

Did I just read where someone thinks raising the strut make a cat run wet? Alrighty then. It's never that simple. Height, angle, CG, prop lift, aerodynamics, thrust cone. I'll tweak a prop to get the cone I want.

On the OP's setup. A LOT more prop or get the higher KV. That hull wont like a 455 which is what I would throw on there but you can't race it anyway so handling is irrelevant. It's down and back boat. Play with some big props. 447, 450, 452, 455. Maybe $75 if you buy them raw. Check your heat after a minute on each test. Sell the one's that don't work. It's a cheap temporary fix until you can get the motor you really want.

My kv is higher than 1050 but it's a Neu. I can run a cupped up 455 so a 450 isn't going to make a lot of heat unless the boat is running very very wet.

[Engelkefarm]

How long is miss geico how many batt packs. The weight and length have something to do with that

[Engelkefarm]

And I never said it was impossible to get the set up to be performing at its peak. But why put energy into something that is not ideal? The amount of money I would spend on props I could have proper motor and take the guessing out of it. I'm sure some one wont like what I say but that's what anyone with 2 cents in there head would do

[Engelkefarm]

And this is for the people that get offended by me saying I have a boat think about all the times you were at a lake and all the tweaking and problems you have done to your scale model that might do 70+. Now just picture that full scale. If you think you just hop in a boat and drive it you obviously don't own one

[Rumdog]

Wow.. Worst thread in a while. The OP already knows everything, and tons of misinformation coming in from every angle.
OP.. just do whatever the hell you want. Seems you don't really need any advice anyhow.
