Confused on what prop to start with?

[d.a.v.e]

I've dug though a lot of posts and have to admit I'm still confused on props. Wondering what will get me the most bang for the buck running the stock electronics? Also wondering if I can get plastic versions or something cheaper then the $35-40 props most folks are talking about for testing purposes before I commit the $40 for a nice metal prop?

I think from my reading I've picked up that the x642 is a good one to start with?

These seem to be the other common ones folks are talking about:

• Octura x442 Sharpened & Balanced

• Octura x445 Sharpened & Balanced

• Sharpened & Balanced GrimRacer 42 x 55 Prop

• I've also seen the Prather 215 mentioned a few times?

Not sure what to start with?

There are certain props that are must have for your prop box and all those should be in there. Your prop box will grow over time. One of my all time favorite boats for this boat and many others has been the grim 42x55. Others will say x642 all the way, but me personally I really dig that grim prop and I actually think it runs better on this boat then the x642 does.... I have the grim prop on my MG right now. Stock esc, but different motor.

A bit of general advice. You have to be very careful when taking prop suggestions. Some guys just like to blast up and down the pond a few times to see how fast they can get their boats and tell you XXX prop works great. But if you run one of these props for more than a minute your going to smoke your equipment. So you have to decide if you want run time or top speed. Fast Electrics are all about managing amps and heat. Keep this in mind when choosing a prop. And no matter what prop you choose, only run it for a minute first time out and check your electrics for excessive heat (about 130 degrees). Then keep adding 30 seconds more run time till you find out where the danger zone is for that prop. Good Luck!!

BTW-This is not a bust on Dales post. Just general info I tell all new FE boaters.

Good advice!I'll try and remember as I will probably push things with my MG and have been away from this stuff for a long while.

I have a lot of props all mostlty octura. X642 m440 m445 m545 m645 and 220 what pitch is the 42 x55 maybe that will be my next addition. Overall I've run about 5 different motors in my boat and each motor I find the best prop for it the x642 and m445 are my 2 favorites I've never had a motor or esc above 105 with any of these props but would sure like to know a little more about the grim since I have seen that as another popular prop. I very rarely even try the 220 any more since I've found it to kill my speed

The Prather 215 is basically the same as what comes on the boat, just stainless instead of plastic. Also happens to be about the same as the Stiletto prop. The plastic MG prop actually has slightly more pitch if you measure it.

In my opinion, based on LOTs of testing... NONE of the props listed above are any "bang" at all on a stock MG... None of them have enough pitch. The 42x55 might be a little better than the rest.

The X642 you have would be a good place to start. Run it, get the boat setup and working correctly, check your temps (and relate that to how long you've run), and if everything looks really good, then there are some bigger props that will wake the boat right up. I wouldn't dive into them, however, until you have everything else working correctly.

If you get it working with the X642, then you can also pitch it up slightly by bending on it a little in the right places, but I'd save that until after you are happy with how everything else is working.

Again, as I've said here many times... the STOCK system is quite capable of being a consistant 45mph system without stressing it too hard, and near 50 if you know how to push things. Have to get everything else setup and working correctly first.

And what prop is this? wouldn't mind running the stock motor on 4s if i can get over 45 with it. Have a ul1 in there right now running around 47 with an m445. Would like to get my vegas set up with either the ul1 or PB 1500kv but i can't seem to get the speed out of it. What is a better prop? Amp draw aside ( running a 120 esc), i just need the motor to last for 3-4 min at a time

The UL1 is a 2000KV motor (never tested one that got over 1970 or so, actually)... The PB1500KV is a totally different motor. WAY less RPM, WAY more torque... As such, the prop needs to have much more pitch in order to equal the speeds. Handling can suffer as a result, so getting everything setup correctly is going to be necessary.

The X645 is a good place to start. The ABC 45x55 is another good one.

I recorded 47-49mph in my stock MG with a Prather 230, with consistant speeds a tad over 45mph... Not sure how that would handle on a race-course, however, and it was pulling well over 70-Amps... I was doing it on a STOCK ESC as well...

[TheShaughnessy]

any 3 bladers that would work? an x646/3 maybe or is that too big? Thought i overheard you saying that 3 bladers are where it is at for racing. I'm running the 1500 in a vegas conversion i got from tony with the x645 and i'm just not that impressed, i prefer to run my MG cause it is faster. Maybe i'm expecting too much out of a spec set up. Should i pick up a prop with more lift for my hydro? Not exactly sure what I'm doing with it.

[Darin Jordan]

Try the X646/3 and let us know... That's a lot of prop and should RIP, but you'll want to watch the temps... I think the motor will pull it without too much issue...

Why not try a PB 1.9x3.0 composite. It has the same dia and pitch as the Prather S230. It's actually nice to play with cuz it's less than $10. You can file it down and sharpen it, and buy a new one if you mess up real bad.

[fuse01]

42x55, good on leopard 2200kv. you will love it but you will need 4s2p. thats my setup

[SWOOP10]

42x55 grim racer hands down for stock set up, balance and sharpen it!

[d.a.v.e]

Where do you guys order your props from? Lost my 42 x 55 today and would like to get a couple different oness already balanced and sharpened.
