Help I Need More Cheap Speed

Bduncan, that sounds like the Seaking ESC calibration, not the stock Aquacraft ESC arming/calibration.

Please verify.

So you had your throttle trim set to middle and it would arm?

I never had to mess with the trim on the Radio.

[Bduncan]

My bad

Good piece of info, thanks. I'll mess with it tonight.

I wonder if this comes into play from the manual:
NOTE: Before or after the above, IF your boat’s power system emits
consecutive beeps, your throttle trim will likely need to be reversed.

Mine does the constant 1sec beep pattern at middle/0 trim, so after rebind, I'll try setting radio to middle, seeing what happens, and if it beeps like that again, I'll try reversing the throttle trim to see what happens.

Let me know how it works out.

When you get frustrated, see if you can get a SK 120A cheap. The SK 180A is overkill and you'll have trouble finding a good spot for it that doesn't interfere with battery placement.

Reversing throttle setting didn't work.

Set it up again.........acts the same way. Fully charged packs. Have to set throttle trim 3 notches down from middle/zero. Obviously haven't tested it on the water yet.

[rickwess]

I'm not sure what to say or how to help. If I can break away from work tomorrow I can plug the stock ESC (it for sale too) into my Revolt and go through the set-up. We're both using Spectrum so it would be a good sanity check.

[AustinWolv]

Thanks rick. I'm hoping to hit the water after work tomorrow so hopefully another data point.

[Bduncan]

I found the stock receivers on the revolt to be less than desirable

[AustinWolv]

The stock Tactic Rx is on Ebay.
I've only been using a MR200 in mine, as I didn't want a bunch of radios for different boats.....just the Spektrum for all of them.

I have two Tatic radio's and both need the Throttle Trim set at 2 o'clock for 100% throttle.

[AustinWolv]

Thanks Mike, I'm using Spektrum DX3C with Spektrum MR200. Going to double-check the arming and then set trim to middle (100%) after arming, hopefully on the water after work and see what happens.

[rickwess]

I'm not sure how much this will be. I just tried my AQ ESC with my Spektrum DX3S and MR200. Using a pack at storage level, I was able to get it to arm properly regardless of my throttle trim setting. I tried 0, B50 and a few in between.

To reiterate the manual:

- Plug in the packs «Beep»
- Squeeze the throttle trigger and hold «Beep»
- Release the trigger «Beep-Beep-Beep»
- Your boat is now ready to operate!

Since you are having issue with top speed, try this:

- set your throttel travel at neutral
- use what ever throttle trim setting to get the ESC to arm
- set your throttle travel to 120%

Rick, I appreciate you taking the time to post and compare.

Ok, hit a lake on the way home. Heavier chop than usual so the Revolt was really bouncing around. Wind was sustained 10mph, gusting 20-some.

Had to set trim -3 to arm. Exact setup as rick outlined.

Then moved trim up to 0 and then +18 (118%) to just below where the prop was spinning.

Runs were back to back, no changes to boat except to change out the packs.

Nanotechs - 36.x mph
Hyperions - 40.1mph

Nanotech temps were in the 110-115degF range, motor and ESC no more than 90 as I recall.
Hyperion temps were considerably lower.....in the 90s, motor and ESC were high 80s.

Boat was definitely not running wet. Only rear of the hull was in the water when heading downwind. Was about 50-75% throttle upwind, as it was too rough for full out.

Chop was slowing things up for sure at times as boat was clearing the water sometimes. Heading upwind, she actually submarined a couple times and caught air, but I got lucky and didn't flip her. Near the end of the 2nd run, the servo mount broke loose so have to epoxy that guy back in place and will run again in a couple days hopefully in calmer water.

Starting to suspect I got one of the lower-performance 1800kv motors........

Anyway, interesting that there was 4mph between the packs.

[rickwess]

40mph isn't bad in large chop.

It you have access to a m445 or m545, I would try those before you do anything else.
