I have had quite a few rtr boats but this is my first attempt at a custom build, The specs are tacon 4074 2150kv and seaking 180 and im gonna run it on 4s. As you can see in the pics this boat also has an oiler instead of greasing the shaft constantly.

nice build.
just remember, even with an oiler, always remove the flex shaft and the end of the days running and
clean it down and dry it. -
How does the oiler work, well???Comment

I have only ran the boat 4 times for 6 laps each and have had no problems or visible wear on the flex shaft, plus I'm getting absolutely no water in the boat from it traveling up the stuffing tube. It's by far the smothest running setup up I have when you compare them by bench testing.Comment

This is a boat I built for Devo. I always use oilers on all my builds if I can. The first time I used an oiler was on a pursuit mono and man that thing was smooth and silent until about 75% throttle. Ever since I use oilers on everything.
Devo,
listen to carl he won't steer ya wrong. it is a good idea to remove the shaft after every run and wipe it clean/dry to prevent rusting and eventually breaking. I like to remove it, clean it, wipe some grease on the propshaft only, then reinstall and fill the oil reservoir.Comment

You need to solider an additional brass tube onto your stuffing tube and then drill a hole into the stuffing tube attach a feeder hose and mine is capped off with a nitro fuel cap. When you start out for the first run fill the tube with oil and run it on the bench with the cap off for a bit, that will bench bleed it. After this add more oil if needed (I use a clear tube so that it's easy to see the oil level) put the cap on the tube and the your ready to run. At the end of the day I usually flush the whole system out with some wd40.Comment

Shawn,
It's just a gravity feed system. what I do Is fill it with oil while I run the motor at idle until oil comes out at the drive dog. that allows the oil to flow down into the entire driveline. Then I just replace the cap and let vibration and gravity do the work. I have considered installing a check valve to allow air in and let the oil run through faster but I've found that too much oil is just a waste and creates a mess inside.
What I do is drill a 1/8" hole about 1 inch from the end of a new stuffing tube. then cut a 5/32" piece of brass tube about 1" long and fish mouth one end with a grinder or round file. Then take the 1/8" drill bit and slide it through the 5/32 tubing and then insert the drill bit with the 5/32 tubing into the 1/8" hole drilled in the stufing tube. Then just solder the 5/32 tube in place. Once it cools take some pliers and pull the drill bit out. Then just install the stuffing tube as usual and run a piece of fuel tubing to a fuel dot mounted on the deck of the boat. here's a pic of one I just did recently and a link to the build thread. there may be more info or pics there

Went out today for some saw runs on the boat and I set a Lake record and personal best top speed of 65.2mph. I have no idea why the pic is upside downComment

That'll be my next build hull. Was it hard drilling the drive-line hole?You live, you make mistakes, you learn, you more forward.Comment

65 on 4s? what is the prop an x450? geezComment

Oh 6s I can see. He said 4s I was like "wtf am I doing wrong?" lolComment

I know of 4S setups that'll do 65mph.Comment
