Like a kv meter..

Mainly we need that adjustable motor mount

Adjusting battery trays guess we nee a New thread lol

I've run 91mph with that rudder. Scuff the mounting surface where it clamps.

Oh boy. I'll try that. Thanks.

What does the 45 mean in your prop? I know the 19 is 1.9" the 15 is 1.5pitch, the 17 is the rake but what is the 45? I think this is the prop that i am going to order just want to make sure i order the right one. Thanks

The 45 is the blade area ratio. Honestly I'm not sure what it means but I wanted to post the whole prop number so there was no confusion. I guess that didn't work.... Haha.

45 means it's severely detounged. 50 is not detounged as much as 45. There really isn't a lot of out the hole difference between the two. They both cavitate a lot on a mono. Not so much at all on a cat. I need to try a even bigger blade area and see how it does.




Something I noticed and wanted to point out.....I had a bit of vibration in my driveline. I thought it was the prop. Nope. So I noticed the nut part on the collet wasn't spinning true. I thought I was seeing stuff. Took it off and put it on my balancer. Way off. Like the hole where it's threaded was threaded probably.015-.020 off on one side so it was wobbling bad. Took one off a burnt up octura collet I had and sounds ten times smoother. Do note that I have not seen one collet or collet nut come balanced (except mbp) but this one was way out. So just wanted to point that out. I think it was just a defective one. Nothing serious but worth checking.


Got a couple sets of batteries charged. Going do some testing tomorrow. Run this thing and a new rigger I finished today. I won't be able to get any logs except the last run. For some reason this Esc doesn't show me anything but the last run. Next weekend we are going camping again at a different place and I should be able to bring the laptop with me and get some good logs.

What props are you going to run tomorrow?

The one my boat likes the best is a 1915 but I may try the 1914 again. Maybe a m447

In one of your post on page 2 your 1915 was your slowest prop. It was your 1815 that was the fastest then your 1914. Am I'm right? Or did you post it wrong? I just want to clarify before iI order a prop thanks.

You are correct sir. My mistake. I got that mixed up with my other boat. Sorry

Today I ran an ABC 1817-17-45 prop. It's a pretty high pitched prop (by far the highest I've tried) and the results were interesting. 50.3mph on 6S and 34.4 on 4S (still stock ESC and motor). As you would expect, the temps were pretty high. I did three sets of 2-3 passes each and then recorded the temps below. I didn't think there was any point in running it any further. The speed wasn't good and the prop slip out of the hole is huge. On 4S it probably didn't stop slipping until 20-25mph. On 6S it just seemed like the motor didn't have the power to spin the prop at full rpm. The ESC handled the prop fine although I bet there would be a problem if I would have run it longer or harder. I think the motor connectors might be at the temperature limit.

ESC - 132
Motor - 111
Motor connectors - 195
Capacitors - 175
Batteries - 105 105

I ran mine today too. Water was rough and wind was blowing pretty hard. Was having a time making a clean full throttle pass. Think the highest I got was 53-54 with the 1914. Flipped it two or three times. Got tired of going get it. I'm really getting close to adding a little epoxy in the tip and some two part foam. It's just too light to run in rough water. It get bent out of shape really easy. My 34" mono would have loved the water today but it's a good bit heavier. I also noticed the higher I pulled the strut up (which wasn't much because it barely moves) it kept picking up speed. I'm going to fix that shortly. I'm pulling data logs as I type this.

[arrover]

I believe that my strut is just about as high as it can go but I almost always have calm water to run in. If I set my boat on a flat surface, and push the transom down so it's firmly on the flat surface, the bottom of the strut is 6-6.5mm above that surface. It appears to be totally level with 6-6.5mm measurements at both ends of the strut.

Travis, are you going to run your new packs ?

Travis, are you going to run your new packs ?

Yes but I was trying to get the boat back to where it was in the beginning first.
