Phil Thomas SS21- Build

[nate]

Iv ordered a PTSS21 from Fine Design.com, It sent out just two days ago and I so cant wait to start the build, Iv noticed Jimmys got his going already, so Iv got to catch up.

Iv got a couple of questions before I buy a few extra props...

I have decided to go ahead and use a Neu 1515 1.5y 1500, and a Hydra 120,

So what would be a good Prop for 4s2p? Ill use (2) 4950mah 33c Eon's.

Maybe an x450 on 4s2p?

Also with 5s2p will an x442 be ok to run???

Thanks guys.

Just remember to fill in all the pin holes prior to painting

Nice. Your helpful.

[tth]

Just my advice, but I would think a X450 size prop may be too big for that hull. But you wouldn't know unless you try. Personally I would stick around X445,M445,M545,X640,X645. Somewhere around there I think would be adequate. But thats just me.

Nice choice in hulls! Why not go for the proven 1515/1Y? I raced against a SS21 last weekend that had this motor and ran a x640-x642 prop,, mid 50's in heat race trim.. One fast little boat! Stuck to the water really nice also,, handled the chop in race conditions very well for the length...

[nate]

Thanks guys, well I did as you said tth, I went and bought an x445, an m445 and x438, that should give me a few to bounce around and see what works best,

I was hoping that this would be a good fast hull, I like any hull with great handling at 50. lol

Is there any good links to building one of these hulls? I see Jimmys started his setup, are there any more out there you guys know of...

One last thing, so your saying this boat on 4s will see 50mph?... I was thinking maybe 49-51mph on 5s...

[tth]

Nate, assuming that you set up the boat properly with a smooth driveline and proper c.o.g, this hull on 5s should see low to mid 50's. On my hydro's I prefer smaller diameter props with more pitch.......thats only my personal preferance.

[nate]

Ok Cool, well thats why I wanted to see the setup on one of the ptss21 running 50's..

[nate]

Ok a few question's, Iv decided to run 5s2p on my hydra 120 and 1515 1.5y...

Should I go ahead and order the individual 5.5mm OSE Bullet connectors to connect the

Parr. Wires into the two deans...

Or Will it be ok to wire it up as I displayed in the following pictures??



???



Here is Some of the Evil thats joining the Hydro...

[Flying Scotsman]

No, your leads are way too long and yes to bullet connectors
Also a close up of the boat, as I am sure it will need pin hole filling

[nate]

Douggie you old fart, Ok thanks, I was wondering about that little connector deal,

I would get a picture of the boat but it hasn't came in yet, should be here like wed. or Thursday this week..

[nate]

Here she is!

The 1515/1.5Y is the wrong motor for 4S. Even with an x645 or x450 you will be lucky to see much over 45 mph. To get the same speeds as the 1515/1Y you'll need a prop like a P235 - a lot of prop for the 1515 and for that hull. You will do better on 5S, there an x642 or x645 should get you into the 50s with a prop that won't upset the hull.

Now that you have the boat in your hands, you know what Douggie was talking about....

I believe I stated up in this thread I have decided to run 5s on this setup.

And I have no Idea what pin holes are lol

[nate]

Iv had alittle time tonight to get the drive shaft (brass tubing) installed,
It actually aligned well..and Has a good tight fit into the hull..

The tubing was cut at 17" and leaves me over 3" inside to work with...

Iv still got to fiberglass it in but im waiting on the Speedmaster strut, Plus I need
to get the bottom sanded out and get ready to fill in the "Pin holes"

Heres the progress...
