2 - PX-335

[MarkScott]

Plan on having some fun this year. These will be full P tunnels, already have a PX-300 for P-LTD. Boats were just finished on the build part. Next will be sealing them in the coming week. Thinking of how to set up the ESC / Servo. Hobbywing 180a, Savox 231-mg for steering. Power will be 4s, batts yet to be purchased. One lower will be a altered Lawless and the other a custom O.S..

 

[MarkScott]

The lowers that will be used.

nice Mark!

What is the black product?

Thanks mate, working on the TT boat and....

Since I have these products around the house, the black stuff is for filling and strength'n the wood and connections. Mix is made from West Systems 205, 423 and 406. 423 = Graphite powder & 406 = Colloidal Silica.

 

[Kris Flynn]

oooo TT and...

I like the sound of those

Looks like you have done very well not to get that stuff EVERYWHERE haha...

 

[MarkScott]

As best as I tried, still didn't keep it clean! Once on the wood, it's in the wood!

Look close enough at those pics, you might figure out that "and" means..

i assumed it was a 3 letter 'word' starting with S

I think then normal epoxy and white glue/filler I use it bad enough...also the black that is sometimes on the burnt edges can go eveywhere...especially evident when you blow you nose later that day after scuffing a few edges!

Just in case you looked closely at the forefront hull, one might see this...



Yep, you know where the lower you sent will be used.

Mark, I would love to see the outcome with the SAW 335. If I remember, that was one I drew up, and never ran, or even built. Will you be going after the IMPBA or NAMBA P record?

Guilty, that be the one. Asked Paul for the PX-335 and he mentioned the SAW kit. Ok, sure, don't have a pond to really test out a SAW boat, but will give it a short shot. IMPBA will be the major record events since the Cincy club holds at least one event a year. 1/3 and 1/4 courses are setup on the lake. Wish we could get access to the pond next to ours. But that is an active gravel pit. If the SAW has any potential, might have to travel to Speed Week again.

 

[MarkScott]

Ok, these are now getting setup. But looking for ideas on how to get the ESC wires out while still keeping the RX box dry. Any and all suggestions will be helpful.

 

[Mike Starrett]

I did it this way then put shrink tubing over the tubing and wire.

 

[MarkScott]

Looks like what I had on the PX-300. Was trying to stay away from metal tubes if possible. Do have brass, copper, aluminum and SS if that is the only way to go. Since both will be full P setups, staying with the 5mm connections. 3/8" thin wall plastic will allow these ends to pass thru, barely. Coping the setup Kris shows on his SAW boat, but he didn't post a pic of how the wires come out. ESC is under the steering servo. Allows the battery to be moved as far forward for CG needs. Just looking for different ideas of what might work. Heck, reached out to Jul to see if he can make something with his latest toy, 3d printer.

i got a ps 295 an did it like Mike
looking good OB Nut
P LTD what kind of props you thinking of?

 

[MarkScott]

The PX-300 P-LTD was running in the 42mm ranges. Since the above two boats still don't have motors selected, not certain on props,. Plus, no one around here runs full P tunnel, these may end up as specialty boats. The PX-335 will most likely end up as a 2 lap TT boat. The club holds at least one, if not two, time trial events a year. The SAW boat, well, that will be a test bed to see how it runs. If potential, may need to travel to a site that holds SAW events. I will be needing new props for multiple boats this year as it is. I've converted a Miss Vegas ( I know, it's not an outboard...) to EP wire drive over the winter. So that will need props also, if not sold before hand.

 

[Marty Slater]

all right keep us posted

 

[David Swisher]

Mark they will be fast in about 3 feet from shore I have seen the electric converted tunnels and they jump out of the water on the throttle,can't wait to see them run

 

[MarkScott]

Well, over the weekend, took the PX-335 oval boat to the Indy/Cincy race. Ran in the Open Tunnel class. Going against many .67 tunnels, wondered how it would run with the big boys. Wasn't disappointed in the performance of the speed. Have to work on the handling now.
