That's great news now move the batteries back. Slow the steering down or turn slower, you are correct it does come about !!!!!! Coolest boat Big fun. MikeDo It Like You Mean It .....or Don't BotherComment

This run was with my batteries all the way back. Maybe some different batteries? Move to one 4s instead of two 2s? Although the weight is about the same, just concentrated lower and more middle.Comment

I have Grim 4s pack. Ran today something is going away in my boat. I have lost 8-10 mph I ran my Grim 4s pack, then 2x2s Hyperion 40c same performance as Grim and 2x2s Turnagy (not as strong batteries) I either have the motor which has lost some power (bearings + drive line OK) or the ESC is my problem. Really don't know what to do at this point? I can tell you the second to last run I finally adjusted the right trim tab level with the hull bottom. This did not slow the boat down but made it run almost perfect up right at WOT. The last run as I was tired and hot I turned the boat over and scuffed the bottom lightly with a 3M green pad (just the rear section) where the boat rides to see what would happen. SURPRISE best of the day and I had to re-trim steering to STRAIGHT which added 1-2 mph. Eagle Tree and Video tomorrow just too tired tonight. MikeDo It Like You Mean It .....or Don't BotherComment

I had a considerable loss of velocity (with some extra noise) when my Revolt's sutffing tube got loose; which augmented the friction inside it. Have you check the stuffing tube has not moved and/or loosened?Comment

P.S. It all started after the day I turned the throttle trim to bring the boat in slowly by some rocks. Never been the correct since....ESC tweaked?Do It Like You Mean It .....or Don't BotherComment

Thank you for the question. My stuffing box came loose during pre-fight before it ever hit the water. Everything mechanically is good. I wish I knew how to check the motor strength? Before I ran maybe if I took a oz/in reading with a short wrench on the cable nut to measure the magnets load on each pole. I hope someone can help as the boat is going to sit until I know what to buy to fix it. I just don't want to throw $$$$ at it.

if it did not let the smoke out take a close look at the motor connectors. Typically" if it does not let the smoke out its not the Controller.. Might..might.. be the motor but start with the connectors to the motor.
Also.. Start over with the radio setup.. turn the TH trim to the 2 O clock position and start over.

Still checking the system over took rear cover off motor wires in there are fine. I noticed that the front end plate where I added a thrust bearing seemed tighter than I remember. I have to take that end off and check it out. I did some research and the 695-Z bearing used in the 1800kv motor will take thrust from the prop no problem. So I can see me removing the thrust bearing. One of the three motor to ESC connectors not real tight. I have the Eagle tree graph and a short video but don't see how to load them right now.

Look and learn from my screw ups.
In my attempt to make an already great new boat better I have caused my own problems. So I want to share my screw ups with everyone so we all can get these Re Volts flying. At 35-38 mph I am too used to it, because my old boats ran this speed. Running 45 mph keeps my attention HA!!! HAVE FUN BE SAFE. Mike
k.i.s.s. Keep it simple stupid..... Oh boy this could have really been bad because I installed a Thrust bearing on my motor and to my surprise it did GREAT job of cutting off oil to motor bearing. NOT A GOOD THING. Removing thrust bearing!!! Since I researched the 695Z motor bear (s) which can handle all the propeller end thrust without any problem! I am buying BOCA Ceramic one's I will let you people know how they work I believe it will be good.
I was lazy and just used ACERGOO instead of walking ten steps to get my Grim Speed Grease. Do not use ACERGOO on any boat cable drive because Yikes it caused quick-accelerated wear on prop stub Yikes. ACERGOO works great on my RC cars and trucks so don't take this wrong. Wonder how they would do with Grim SG? BTW ACER offers SIN Lube which I did use on my motor bearings nice lube.
Grim,
Thank you for designing this boat I promise not to screw it up anymore.
Mike
P.S. Are the 695Z bearings Flanged or non-Flanged? And have you tried them?Do It Like You Mean It .....or Don't BotherComment

Not a mistake.. a guy has got to try things.. its in out blood!
Non Flanged and no I have not!

I am running a m445 prop and running 41- 44 mph. Raced against an older supervee last weekend and was reeling it in on the straights and certainly have the advantage on the corners as well. I will also say raising the strut up a bit will lower the hull in the water and reduce the chine walk. I did this on mine and saw a noticable difference in the handling of the boat for the better. I am setting the battery about mid point in the tray. Any further forward and I notice there is a greater likelyhood to stuff the boat in a good race chop. Not too fun to hold your breath as you wait for you boat to come back to the surface....or not...Comment
