Darin's Top Speed 2 FE Conversion...

[Darin Jordan]

Hehehe like I said I got a little tinkering to do..

You may need to trim back the cav plate to fit the 235... the 230 MIGHT fit...

Hang on!

OH, and REDUCE your runtime and watch your temps... Your boat needs to be dialed and running loose to run those props without desoldering a connection or worse... My batteries started to get warm with that setup... but I won the races... :D

Got rain forcasted tomarrow, but I will try those props to I am easy.

You are driving a BOAT.... What, are you afraid it might get WET???

The problem I see right now is this hull handles so good the SV power system may not be enough to make it hairy like I like it.

You don't have it setup right then!

Put a Prather 230 or Prather 235 on there... Then get back to us about it not being "hairy like you like it"...

[ice329]

The X642 is definatly the best choice of the props I have here to try. Still gonna give the 4 blade a shot after I balance it. I still think there may be a better choice then the X. I will do a little adjusting with the X642 and see if I can get it like I like it.

When your right, your right. The 1742-3 is not a good choice either. Wicked fast when you can get the prop to grab, but overall not a good choice. Both the 1740-3 and the 1742-3 will but up later on the swap shap... gonna go with my favorite SV prop next and I am thinking it will be the one... X642 next up

[ice329]

The reason I went to try the 1740-3 and 1742-3 is because my first set up I didnt like so I called Octura and we talked on how to fix the problem but ultimatly it was the set up, so I will at least try the 1742-3, I also got a 4 bladed prop to try but I also will try the x642 and which ever one I like the best is what I will stick with. Since I dont race I kinda stick to the prop I like for my pond. If not there will be a few 17 series props up on swap...

I will tune down the stearing trim.

I wish I could get more choppy water going, they handle so good.... when I get her dialed in I will take a little vid. Thanks for the info

[Darin Jordan]

I will try a differnt prop next before I make any adjustments, going with the 1742-3 next.

You might want to rethink your prop choices... Aren't the 17-series "lifting" props?? You don't need that...

I've had the best luck using ABC 42x55 or 45x55, or a Prather 225, or, Like Tony has suggested... the X642 or X645... Just watch your runtime and temps...

re :

Keep the steering dual-rate trim at a minimum; just enough to carve the bouys on a 1/6 mile course. Ive found that a plain 'ole X442 works great, but a X642 for racing gets going faster but draws more amps [ OK for a 2-minute race on 5000+ mah]. Fun stuff, eh ?

[ice329]

Oh yaaa Much better.... I got some adjusting to do but overall its like night and day. One little problem, I hooked it a few times. Probly a little adjustment. The next thing, the prop did suck some ait a few times, I had the feather the throtal and regrab the prop. The batteries got to 129 degrees so...not sure how warm I should let them get, there 5350 7.4 Poly RC packs. I will try a differnt prop next before I make any adjustments, going with the 1742-3 next.

There are a few option one can use, there is the:

REK lower unit (some sorta plastic) +- 100
Lawless lower unit (aluminum I believe) +-150
Angle Drive +- 100 (aluminum)

[SLAUGHTER_AUS]

What type of outboard leg are you guys using on those?
That is the only type that seems to work?

re :

Good luck & bon voyage, Joey. With a little dialing in, this boat is FUN ! Let us know how she does

[ice329]

This thread is responsable for me needing to do a TS2.... I saw Darin doing one and needed one to. I finally finished or should I say refinished it. This time I think she is right. First time around I had to much weight forward and could not adjust it and the servo was not strong enough and I did not like how the stearing was set up. Took care of all of that and also put a better jack plate from the capt. Thanks to a few people on this forum for info and parts, I finally finished her again. I will be giving her a test tomarrow with a 1740-3..we will see what happens

I like to be able to turn my boat,I guess if I just wanted to go as fast as possible I'd just throw the biggest motor on there I could find and a hv esc, crank the motor down, and get ready to go fishing alot.Anyone notice how some of these tunnel hulls are nicely bowed on the bottom,makes setup fun.I started keeping a setup logbook for my boats,with cause and effect.I found what works for some,didn't always work for me,and vise versa.

[Stinger9D9]

Well, at least it doesn't sink...

I took the boat out a couple of times this weekend. The first time with the prop shaft at 1/8" up, and angled at 1 degree. It ran well enough, just still a bit slow.

The next day, I angled the motor up to 3 degrees, then slow charged (1/10C) up 13 IB 4200 cells (I had a single "booster cell" wired up). The boat took off across the pond well enough, I turned it back toward me, and as soon as I went to turn in front of me it hooked, but now with the speed it had, it flipped.

I wasn't sure if it would stay afloat, and was preparing to watch it sink away forever. (I will never swim after a boat). The good news is, it floats great upside down, the bad news is, the receiver got soaked (the ETTI esc is crazy waterproof, so it was fine). The trip to the pond was over in about 1 minute and I never got a decent chance to see how it ran.

My real question is this video:

Is this guy really hitting 40 mph with only 3S? I know it looks like it could be 40mph, but the question is, is this possible with the setup he is describing? It doesn't seem like he'd get the prop speed needed.
