Help I Need More Cheap Speed

**Fluid** · 08-14-2013, 03:53 PM

Two things will get you more "cheap" speed. Set the hull up to run loose, on the back part of the hull. This reduces drag and gives free speed - but will make the boat more liable to blow over. Second is another prop. While yours may work okay, club members have gotten into the mid 40s with an m445.

All the power in an FE boat is in the packs, and better packs mean more speed. Yours may be fine, or not. You can scuff the hull bottom in contact with the water to reduce drag a big more. Next it's $$$.

Hey Fluid thanks... can you recomend a good pack and I am not sure about how to set up the boat to run loose but maybe I will take another good look at the rest of the topics to get some hints.

Mike.... I have read a couple of your other posts that mentioned that and I am wondering if that is my biggest culprit right now. I am going to go through the manual again and try to see if that helps. Its funny too cause when I read that post a couple of weeks ago it really set something off in my mind but I went ahead and ignored it and now that you re emphasized it I think I am going to try that first.

I might get it out in the harbour tomorrow night and see if I can rebind and set up my txt again and try to play with the trim tabs to maybe get the bow up a bit more to have less boat in the water. I hope this is the correct idea. Again thanks for all the help I really want to beat my friends Impulse 31 but right now he has me good.

Ok it seems like i am binding my txt correctly but I may have the settings wrong... I have two questions:

1. Once you have binded the txt to the reciver do you turn the throttle trim up after or leave it at the same point?

2. Can anyone take a picture of thier txt of the trim and throttle and (N-R) settings as they are when they bind it so that I can set it up the same way. I know this is a pain but after your post Mike I really believe that my lack of speed is comming from the way I am setting up the txt. Although if I am wrong I am going to be frustrated ... lol.

Whats this TX/RX setup stuff I'm reading about?

I'm not running the tactic, I'm running a Spektrum setup. Is this something I need to worry about? My revolt did 38mph with a single 4s pack and a 440/3, fins all the way up and haven't touched the trim tabs or strut. I saw 37.5-38.5 comment and was wondering if I may be falling into this issue because no matter what prop I use it does 38ish mph.

My radio won't bind until its down to about 4-5 o'clock... I think that is why I am so confused. It won't beep at 2 o'clock then I turn it down to about 4-5 and it will beep. What does the (N-R) switch... does that effect anything? Does it need to be in one or the other? Doesn't say much about that in boat manual and it doesn't really go to much detail in the radio manual.

I feel like i must be doing something wrong because if you can hit 52 MPH with a similar set up and I can't seem to hit 40MPH that seems like a big difference. Thats close to a 38% difference in speed.

You will see nice gains in speed by adjusting the strut upwards. The Revolt is a V hull so its hard to go "too far" trimming up unless you are running into a strong headwind (yep, i blew mine over running too much trim into the wind). Just like a real boat, the drive needs to be trimmed up to carry the bow up and out of the water, reducing the wetted surface on the hull. Air offers much less resistance than water, so the less area of the hull dragging through the water, the faster the boat will go. Have fun! You're in the right place!

Thanks Fox I might try putting up the strut a hair and maybe adjusting the trim tabs up some more.

Mike I just did the speed calculator and apparently I am not that far off at 38... it calculated me at 40 mph with my prop. I am not sure what you did to achieve your speeds but I sure would like a small chunck more so I can run with my buddy's impulse 31. Stock he GPS's his at 47MPH.

**Phoebe** · 08-15-2013, 01:50 PM

Suggest you guys give the stock Impulse Prop on your Revolts. I get 7 or 8 minutes run time, flat out, at 46 mph.

Tryed the boat in the harbour last night... its not the txt... the boat is slow.... bummer. Could have sworn I would have been able to get a bit more than what I did. Gonna try raising the strut a hair and the tabs and see what happens.

**chrispycontrol** · 08-19-2013, 01:06 PM

I raised my strut maybe 1-2mm and I noticed a nice jump in speed.
And I have everything sharpened to kitchen knife status
gps last night 43.6 with stock prop.

Wow really... i am getting really frustrated now... I think I must have the slowest boat out there...

**Bduncan** · 08-21-2013, 08:52 AM

Try ose 47 mm carbon prop trimmed all the way up. Run dual watercooling and try ahort runs

**skeeler** · 08-21-2013, 09:08 AM

Stupid newbie question: When adjusting the strut, it seems like you have to bend the stuffing tube. Is that correct? Is there a risk of fatiguing the tube and having it fail on you?

Thanks.
