New Ride Pads on the UL-1

[tlandauer]

I had suffered yet another episode of the "Bermuda" triangle , it happens with the Tactic and usually the boat stops, but it kept going and my poor depth perception was telling me that the boat was turning , my foot! So the first time it went into the reeds , no damage, the second time straight to the shore .
I did not run the boat for a long time because the ride pad surface was terrible, the boat wobbles a lot, since I had to fix the hole on the sponson , I decided to put a simple ride pad made out of G 10 FG plate.

Already filled hole, I used "finishing epoxy" mixed with West Marine 404 High_Density Adhesive Filler. I did not use Bondo or West Marine "MarineRX" because these materials don't work well on edges, they are great if you have vast expanse of territory, on corners and edges I found out they sometimes they will chip away a little:DSCN5793_6128.jpg

New motor mount

I have finally gotten tired of the misalignment and the non-rigid nature of the stock mount, but I found the most popular TFL two ring motor mount is too wide for the tub, there will not be any space left for the batteries to rest on each side of the motor, and only batteries with measurement of 135mm lengthwise can be fitted laterally, so I want to have the option of placing the batteries longitudinally. I found this TFL simple mount in my parts bin.
I fashioned a wedge to angle it and the floor is rather thin so a plate made out of G10 is used to spread the load. This is a FG prototype board, it is lighter than a solid plate with all the holes .

Good Lord Tim, sell the junk radios and buy a REAL radio system. You will eventually thank me....

I am thanking you already and everyday!!!
You will be happy to know that as of yesterday I put in a Spektrum, no more Tactic. I have grown fond of antennas which wasn't the case when I got the boat three years ago.

Some updates: this run today I had on with a X642 prop, this is a faster prop (compared to the Grim 40x52/3) , also liked the X440/3 a lot. I tried the Grim L42x66, while I liked the speed, the lifting characteristics introduces new issues that need to be dealt with. So I stayed with non-lifting props.
I will not run my UL-1 without the Air-Foil, this much I can tell you.

The untold story here is that after the new pads were installed, the ride got much worse---I kind of expected that as the clean articulation on the pads exaggerates the inherent problem with the mushy lines of the FG hull. The port side is always jumping out of the water and this motion will amplify as the run continues at WOT until a barrel role is commenced. After careful reshaping and lessening the AOA on the port side, the ride is better and calmer, and the video shows the improvement. I raised the strut a bit because the Air-Foil is doing its job. I did not post this in the Product Review Section since this is my observation and is not solicitated from the maker of the Air-Foil.

Thanks for the info.

Is this a typo, "this run today I had on with a X462 prop,".

Was it a x642?

Indeed it is a typo, thanks for pointing it out. X642 it was.

X642 - Have you GPS it?

X642 - Have you GPS'd it yet? Thanks,

[tlandauer]

Sorry... not yet!

Very slow, GPS'd at 48mph. Yours on your signature is alot faster than mine, obviously I am doing something wrong, but summer is over, work is piling up.

From here, 48mph and stable looks Great! Especially when you consider it's starting point.

When you have some free time, may I see a picture of your strut / prop angle settings. ...no rush.

Using your detailed information - got New Ride Pads.

Thanks,

Here you go, sorry for the delay!DSCN7497.jpg DSCN7498.jpg DSCN7499.jpgDSCN7501.jpgDSCN7502.jpg

looks like she runs beautifully smooth and flat. I have a couple questions, first is about the GPS you are using, I have been trying to source one out so I can compare what each mod does but have not been able to find one. would you happen to know where I could find one ? second question is which air foil are you using? the air dam that goes between the sponsons under the boat or the one that gets taped on the front between the sponsons? thanks John
