At the lower voltage (lower speed) it is possible you won't see a gain with that prop. It may possibly be a little slower since you went down in diameter, curious to find out. But as you up the voltage and speed it should start to shine. The abc props do better at the top end of the speed range it seems. The first thing you will notice the bite getting on plane is a little lacking but it is not a big deal.

I am using the 1914 and with my 1480kv at 4S it was only 1 mph or so faster than the M445. I was really surprised because the 1914 makes the m445 look tiny. But as I upped the voltage the spread increased. 5S was 5mph. 6S about 7mph on average. I think the 1814 should be a good model to coincide with the m445 as well.

Woot! The water was perfect tonight and I was able to get in several runs. Hit 47.3 with the Nano Techs. Swapped in the Revolectrics and hit 50.2(my goal on 4s!) with no other change. Everything came in cooler also. Mega happy with that! 4s, 1620kv and m445.

[Jamey]

Wow that is way faster than expected. You sure that new motor is 1620? lol

That would be 100% efficiency and only like 11% slip. Pretty amazing. My 1480kv only went 39 with a m445!

[Turbo Dan-O]

Well, I was pretty sure but... I got it from the swap shop from member "zhevers". That's what he said it was. I looked all over it but didn't find any numbers or anything. Hmmm, now that you mention it that does sound like a lot! It went 41.3 with the stock motor and unbalanced m445 on the Nano Techs. I have since shortened and knife edged the rudder, gotten the prop dialed in and of course added the TP motor. Think that would be worth 6 mph with the same KV and batteries?

[Jamey]

41mph would be about right for 1620. I would estimate your new motor around a 2000kv +/-100. Doesn't really matter it's just that 5s and especially 6s will be pretty hot if that really is the case. Use caution when and if you up the volts.

Try a 1914 or 1915 and you be close to 60mph on 4s!

[Turbo Dan-O]

Sooooooo.... I just pulled the trigger on a couple of Revo 3s packs...

I'll be careful. Everything came in around 85* with the Revos(50 mph pass) so I think I still have some room. Also, after seeing what kfxguy has been doing with the SF300s I'm on the lookout for one of those now. Insane!

[Jamey]

When I order revos I'll probably do 6S2P with a couple 6S 4200mah. I am already using 7200mah 60C batteries so I would hate to drop down to only 5500 plus I think a little extra weight will be nice.

85? lol Must be nice. We're still pushing the 100's here with water temps at about 90. My motor is a good 10 degrees warmer than yours before I even connect the batteries Yeah I would say you are doing just fine. How long did you run?

So did you get your hatch water tight without tape? I think that will be my next project. Tape is a pita but I get zero water in the hull sitting upside down. Oh and has your motor mount busted loose yet? If it hasn't it probably will lol . I soaked mine in acetone to clean the old glue off and epoxied it back. Holding good so far.

[Turbo Dan-O]

Yeah, it just started cooling off here in middle TN a few days ago. Not sure what the water temp is but it's still more than fine to swim in. I didn't run it long. Made 2-3 passes each time and brought it in. I did take it back out and beat on it some more with the Revos. Everything was cool but the ESC. It was getting a little warm. I wasn't driving it very nicely though!

Still working on the hatch seal thing. It's not quite touching in the middle of either side. The hull is just not made perfect. The tape I used is only 1/8" tall so that doesn't leave much room for things to be off. Hmmm....

My stock motor mount is still holding strong. It's epoxied in there pretty good! We'll see how long it lasts...

Also, just got my parts in from OSE!!! Super fast shipping and got an email confirmation. Very happy with that!

Going to be adding an MBP collet and trying out this wicked looking ABC 1715 prop!

[zooma]

A while ago, I reduced my flipping by moving the CG forward, but lost a few MPH. Thanks to the recent advice on this thread, I lowered my tabs twice, while moving the CG back, and restored the speed. Made two runs today without flipping.

[Jamey]

I am very curious to hear how that abc prop does. I am thinking it will be a little faster but just a guess. The m445 really is a good prop in my opinion. I am positive the 1814 would be faster just not sure about the smaller diameter 1715. The suspense is killing me

Yeah zooma, I went through a little bit of work getting my cg moved forward. I only wish I would have tested tab adjustment first. Probably would have saved me the trouble

[Turbo Dan-O]

Just tried out the 1715 and it picked up a bit of speed(51.0) and ran cooler vs. the M445. It did slip pretty good but I can deal with that. 4S of course. I missed FedEx today(they have my 3S Revos) so 5S isn't far off. Still, I'm happy with 50+ mph and under 100* temps in play mode. Also, since I have learned how to adjust the trim tabs it hasn't wrecked of flipped one time! Sweet!

Any advice on stinger adjustment? Mine is set with just a tad bit of negative angle. I might try it level and see how it does...

[Capt'n Crash]

I did the same thing, went from a Revolt 30 to a Pursuit. Main reason is I liked using a 4082 Leopard can, and the Pursuit was a better platform for it.

With the setup you have, you are about 50mph or so range on 4S. If you go 5S, you will get around 60mph, but that motor is capable of 6S if you choose in the future. As for the lipo cutoff, don't set it too low that the batteries puff or drain beyond 20% of capacity, wont' be worth those extra few seconds of runtime. Stick to whatever cutoff leaves you with about 20% or more capacity and non-puffed batteries.

However, I highly recommend you reinforce your hull and canopy, even at the speeds your running now. My brand new Pursuit cracked a large seem on the left side from just a minor roll over at less than 50mph.

Just use some fiberglass cloth strips and resin to reinforce each seam, and also do a fiberglass layup for the canopy which is already very flimsy.

I recently had a 65 mph flip and roll with zero damage after these minor reinforcements.

Also, another tip is to make sure you blue loctite the bolts holding the stinger on the stinger mount, and the bolts holding on the stinger adjustment rod. These things will unloosen quickly otherwise.

Thanks for the tips SD. I think I will keep it to 4s as I like being in the 50 MPH neighborhood.

I've been keeping a close eye on all the nuts and bolts and so far nothing has come loose or gone missing during the adjustment phase.

Battery capacity after a run is 38% so I will not be changing the LVC.

I've had several more runs since I posted last and everything is running great, no rollovers, cracks or spidering of the hull paint so far and the batteries and electronics are holding up just fine.

I have this winter to do some hull reinforcement as you suggest and I'll be adding some plywood battery trays to the hull to take two 4s packs on either side of the motor for better run times.

I'm very pleased with this boat and I think my Revolt 30's are jealous of the Pursuit by now

Happy FE boating!

Hello,
in pursuit with motor 4082 1600kV, what is better battery choice, 2x3S 5000mAh 90C in serial or 1x 6S 5000mAh 70C?
Tnx

[Capt'n Crash]

My esc is located just in front of the motor so i found it easier to balance the boat center of gravity by having two batteries on either side of the motor. Much more room to adjust them forward or backward in that configuration.
