pics of props and rudder/mount

Here are a couple pics of the props.They are long.Not much of the stub shaft to stick out.I had to loosen the collets and pull the wire drives out a tad.Not a big deal.And heres a pic of the Speedmaster rudder and mount.I had to put the mount bolts in from the inside.Its a little tight in there to gets the nuts all the way to the back.It works great-blow overs and general wipe-outs dont mess this one up like the stock junk does.And it has a break-a-way.I also moved the steering servo to the middle.Notice the water outlets now come out of the fake exhaust pipes.Ill use the stock outlets for the motor mounts when I decide I need them.

Interesting, mine haven't come loose yet. That is a great speed for 38mm props. Are they the ones from kintec racing? Did you balance them yourself??

I was wrong.I just talked to Jan,they are NOT sharpened and balanced.Guess I need to get mine done.

No, 57.7 mph on the cf-40's. That's the first I've heard of the 38mm props.

SORRY,

You lost me on that one.

I am liking this a lot! Gives it a scale look when running when the water comes outta there.

I'm bettin you pick up a couple mph from a good sharpen and balance!

Yeah.I want to send them and a couple of 442's to chuck-"egneg" to see what he can do.Im kinda thinking I might be able to run the 442's safely.My temps with the 38's are 100-116 for both the motors and esc's.Really dont want to burn anything up.My main goal for now is to beat my buddys Apparation.Friendly of course.Might just have to buy the 2 Align motors in the swap shop and run on 6s.

He does nice work. I have several props from him. I can balance & sharpen my own, but it's not fun for me, and his come out soo nice!

Do you have any suggestions on stringer settings when moving to a larger diameter prop?Is there a general rule of thumb to it-say when going larger diameter you put the prop lower in the water?

Mine seems to like a little positive angle on the stinger with the larger props. When I ran my 32mm props if I didnt set the stingers neutral or slightly negative, the boat would cavitate a lot before getting up on plane. Not sure if there is a general rule of thumb for stinger settings. Thats whats so good about having a gps. You can make small adjustments and take measurements to dial your boat in for max speed. BTW, I dont have the newer black stingers with the degree indicators on them.

Nice thing about a strut as compared to a stinger, is a strut you can adjust the prop depth seperately from the strut angle. With the stinger you are adjusting both at the same time. Setting prop depth is pretty critical for max rpm/speed. Run your prop too deep and you can really heat up the electronics too.

Sorry to hear that about you not having the black stingers.The indicators on them arent that accurate anyway.Thanks for the suggestions on the depth.I just had to take out one of the motor mounts again because the mount screws keep coming loose from the steel floor mount.I used blue locktite on the screws before.Now I used green.They better not come loose again or Im making my own mounts that will be one piece.

SPOT ON,
the indicators are not your friend on this boat
beacause the stingers mite not be in the exact same place....(like mine)
keep doing what your doing with the adjustment and you wont go wrong
and larry i was wondering if the props your using were the ones i mentioned.
didn't meen to lose you.....
(kintek 38X1.45)
whats every bodys apinion on bearings vs bushings????
the reason i ask is 1 of my bearings went bad and locked solid(no movement)
but it had no affect on the shaft???and no affect on the speed???

i did the same thing but took out the fake pipes and went with rivits...
nice job...
can you see the water come out when you buzz by?????
i cant but i know it works because my heat is around 115-130
plus if i use my pump to check the fittings it flows out nice.
check out the pic (avatar)and you can see the difference.

Thats the props.They work great.Its looks like they are balanced.They have the same look a balanced prop does.And the edges arent dull at all,but they arent S&B.I still picked up I think 4 mph with them.Gonna get them S&B though.
My opinion on bushings-dont use them.Ill be upgrading to the Boca Ceramic sealed when my stockers go south.
