P1 kos 35" offset rudder.

[lenny]

With the offset rudder mod,
The rudder is 1 1/2" offset from the stinger to the starboard side.
I made a aluminum off set plate that is 2mm thick and 24mm wide and 53mm long,
Than drilled 4 hole for the mounting screws after I traced the stock mounting holes to the plate.
Two for above the stock stinger rudder mount holes that I used longer screws and nuts for,
And two to mount the stock rudder bracket too with the two stock screws that were for it.

Lenny,

Congrats!!

Part two,

Way to go! I think she is running really well, very smooth, I am sure the off set rudder made a real differance, I always had to slow down a bit for turns because I did not want to push the limit, other than that with 3s the attitude looked very similar. I think yours will definately run better with 4s at full speed.
Liked your ESC stand, nice layout inside. Infact that is some operation the interior had gone thru.
Did you add more reinforcement for the transom? I worry about the transom not having a doubler.
My turn fins were installed much lower than yours, more drag I am sure, also what kind of trim tabs are you using?
If you don't mind, I will post more questions, just got home, very tired.

[lenny]

No problem,
Ask what you want.
Yes, Just little rigging in the modding to see what works, But nothing permanent.
I try to use what I have on hand and make it work.
The trim tabs are the new stock one, I just modded them.
I did not do any reinforcement yet, The transom seam to be strong enough on it om I think.
But the hatch need to be modded for strength encase of a good blow over I think.
That will be next in line for some chop.
I need to get a good cheap used camcorder for better videos.

Do you have any pictures of your boat ?
So I can see what you are taking about on the strut bolts and strut plate.
I found some things wrong and need to fix them,
The stock bullet on motor to esc are a weak link,
I temped them at 155 f and that heat is power loss and not good.
And I will change them to 5.5 and check them again.

Still running on 3s1p & 3s2p, Best prop so far for speed was the x442 at 30.5 mph temps good.
But I do see some torque roll and will try a grim 40x52/3 and a L40x57/3 or a x440/3,
To see if they work or help any with the balance of the boat.
I had my first flip over and it got a little wet inside,
But all is good and still working.
I just need to mod the hatch and seal a little bit more.

HI,
Thanks for asking for the pics. Had a concert last night and I was beat! I thought the stock bullets were 4 mm jobs, better than Pro Boat's 3.5mm, lol... they were ok on mine, may be you had a bad solder from the factory?
The X442 was also my first chioce but I nicked it on my maiden run.
As you can see, my boat is stock, only thing I did was put extra FG from the battery platform forward on the floor area until I can no longer reach under the deck. Also near the bow on topunderside of course. The trnsom shot you can see the epoxy encased stinger plate. All the nuts are epoxied in, so I don't want to loosen any bolts to damage the epoxy inside.

more pics, never know how to upload!DSCN1788_1327.jpg By the way, you will see a little chunk of the rudder was gone along side of the leading edge, I assume the previous owner has a mishap, I ordered a new one but couldn't tell the difference so I am using this one, it has no ill effects on ride quality so far as I can tell. Are your batteries by the side of the motor? I bias mine on the port side and still notice when running the boat rolls to starboardside, I am sure you will have her dialed in real smooth.

Ok, last pic.DSCN1789_1328.jpg, sorry to take this long. Slow at computer

[lenny]

Yes I know what you mean about CP,
Let a lone if you can not spell. lol
I love auto save on hear.

Ok, Mine looks about the same with the plate and stock epoxy over it,
If you did the rudder offset, You will only remove the stinger bolts and not the plate.
I would need one measurement from the stern starboard side to the trim tab adjusting bolt with nut.
You need 1 1/4 "for the rudder arm and bracket.
If you want do the mod I will walk you though it.
You will use water hose hole for servo rod and old rod hole for water hose.

[tlandauer]

Thanks for the offer, you mean you need measurement from me? right? I might not be able to get it now, but will attemp later, concerts this weekend! BTY, that is brilliant to use the existing holes for the mod, I was dreading to drill holes.

[lenny]

Ok, last pic.[ATTACH=CONFIG]71243[/ATTACH], sorry to take this long. Slow at computer

Yes you,
That port side battery plug wire cover looks scary
I just use a cap on the red wire plugs.
Nice grease cover you have, Looks like half a shot glass.
What boat is that in your avatar ? Looks nice.

[tlandauer]

Yes, it looks scary, I will cover them,thanks. My neg. are covered with heat shrink tube conformed to plug, actually very snug, since that is male plug, but I see the exposed bit of copper plug coming out of the positive.
Got idea from a pic here with the grease cover, just cut the epoxy mixing cup and you have it!
My trim tab base is so wide, I am not sure I understand your required clearance for your rudder arm because I am afraid I don't have enough space for it. You can see it is a "double Decker Version, top plate will get in the way. "...from Stern starboardside to trim tab adjusting boltwith nut"? Sorry
