'69 Pay N' Pak Hook Tail Shovel nose 1/10th scale ML Boatworks build thread

[cybercrxt]

Well, I have not done a build thread in a while, and finally getting to build a boat for myself, something I have wanted for a while, a 1/10th scale. Here is the thread so far from IW. Mike:

What does the guy with over 100 laser cut scale kits do when he is bored...cut out a frame kit on the band saw instead of purchasing a laser cut kit of course! I printed out a set of 1/10th scale plans from my laser cut templates,and decided to see how much I like my new bandsaw. I have not cut a frame kit in probably 3 years, so I wanted to see if I was up to the challenge! 3 hours later I had the kit cut and fitted together! I took the paper drawn parts, and contact glued them to the face of the ply I was cutting, and ran it through the band saw and it worked pretty well. My laser guy is backed up with my customers orders, and I have had the itch for a shovel nose build for a while, so decided to just do it. It will either be the Hawaii Kai III, '70 U-00 Lil Buzzard, or the '69 U-25 Hook tail Pak. I am leaning towards the hook tail. Enjoy the pics, Mike

The real boat:

This build is turning into a favorite! I am really liking the shovel nose looks and build. I got a LOT done last night. The rear half of the boat is all glued in, and the front half, while it looks glued in is just taped in place and ready for glue. I still have to put some basswood sticks into some of the openings which is why I have not glued it yet, but it is good and square on the granite, which is nice! The only thing I hate is I may have this thing done very fast and I am enjoying the build to much! I do plan on just offering a sheeting kit for this 103 1/10th scale kit since I am making templates. I actually already had the floor pan designed in cad, so I just printed it out on paper, and hand cut it like I did the rest of this kit. I have decided it will be the '69 Pay N Pak Hook tail. Here are some pics. Mike

Nice!

Gorgeous! What are you going to use for power?

[HydroMike]

Nice I like it

Thanks a lot guys. I ordered a scorpion HK-3226- 1600kv for it. Not sure what prop to use tho. I want it to run about 50mph. I went one size larger in motor than the pacific northwest guys are running (the HK-3026-1210kv), so I will have about 150 watts more of ability, so I think I can run 50mph. I weighted the boat last night, in its present state (in pics below) it weight 1lb 8oz...does this sound OK Jim (Clark)? Here is my post this morning from IW:

I am making sheeting templates as well, so this will be a full kit available. Here is last nights progress. All sticks installed. I was hoping to get the sponsons sheeted, but ran out of time. Did get the sponson non trip pattern made and have wood ready to cut when I get home! Mike

[JimClark]

Weight sounds about right. Current boats in RTR condition are weighing 5 to 6 pounds. As far as the prop goes those scorpions can handle bigger props so ax447 to start with and you may be able to get as high as a 51

[cybercrxt]

Jim, even with the 1600kv I can use a x447? I know you guys are running like 1210kv with the x447 right? So should I use something smaller? Also, what are you doing for turn fins on these boats? I am not racing, but I would like it to look real and not put a modern turn fin on the heel. Does the small skid fin on the inside of the sponson work well as the rules in Classic Thunder discuss as far as depth and length?

[JimClark]

Classic thunders turn fin is too small in my opinion I would go with the namba rule for the fin. Some in CT are using the 51mm props with the scorpion. Are you going to turn right or left?

Nice I am enjoying watching.

Thanks for the info Jim, I got the sponson non trip and ride pads on last night. I plan to put a narrower secondary ride later in the build, but want to get the inside epoxied, hardware fitted, and top decks on, then I will revisit the bottom so I don't risk nicking the pad while doing other things! Also started making templates for the top deck. I found doing two center front strips, and two outside strips, and then rear separately will be the way to go. The compound curve on the hull this size with 1/16" is just to risky to me as I do not want waves in the decking where filler has to be added. I am making templates as I go so this can come with the kit. So far so good! Also made a little skid fin last night from a turtle damaged Virginia Craftsman sport 20 fin. I cut, shaped and cleaned up the edge and face. It should do fine for a boat of this size and speed, and the fact I don't plan to race it anyways! Just want a good realistic running hull. Mike

Looking good Mike !
I think you should build the boat to NAMBA or West Coast rules though, It will run plenty fast with a PB1500 kv motor, 062 wire drive and a 45-48mm prop.

TC, I already ordered the motor, and also have an adjustable strut I want to run. I know this will limit the resale ability, but I tend to hold on to my personal scale builds, unlike the sport hydros and tunnels I have sold. I am sure that is why you were asking? haha (everyone knows I get tired of my boats and sell them often, lol)

[T.C.]

OK I understand and hope you do keep the boat.
But If you use a .062 wire and mount the adj. strut to the inside transom or inside on the bottom you will still have plenty of adjustment, just use 1/8 brass stuffing tube and make a 1/8 to 1/4 Ferrel for the strut. I am sure Wolts can hook ya up, if not let me know I will.
Just seems a shame to build a beautiful boat (and I'm sure it will be) and it not be legal.
I would bet that someone on this forum would give you a 1500PB motor . lol
Besides you may like turning left !
