HPR C5009 Build - Nor Cal

[lavigna]

Hey all,

I have been on the boards for about 2 years now. I have gotten a lot of useful information about builds, and wanted to share mine as well. I got my HPR hull last year, but have not done much with it yet. I am finally getting underway on it now. I am hoping that my own build thread will keep me motivated to get her finished and in the water.

She is a HPR C5009 - I ordered her in CKF but got CKF/Kevlar instead. I am not thrilled with the appearance of the kevlar interior, but it is not too bad. I also have all of the HPR hardware that you can get - drives, rudder, motor mounts, servo mount, etc. I want her to look as clean and tidy on the inside as the outside. I am blown away by the work I have seen on here by Christian and others. She will be my first cat build, as well as my first FE build. I am still undecided on the motors or electronics, but I am going to need to get that sorted soon so I can begin to get my mounts laid out.

I dont have much to show yet, but I hope to soon. So far I have reinforced the transom area where the drives will pass, as well as filled and reinforced with cf the inside of the rudder mount (not pictured). I just ordered some black tint for my epoxy, as it looks very white in the photos (pretty clear in person). I am using West System epoxy and have been very happy so far. I have also done some slight rudder mods that I will post up later.

Nice dude, will follow for sure Along with building my own 115 good luck with the build

DSC_8262.jpgP1010383.jpgThanks Nata. I have been following your builds very closely, and have gotten a lot of great info from them.

I just ordered myself some cf panels for interior work. In the meantime, I cut out some section of the cf bulkhead, and cut the scrap into squares to reinforce the top of the arneson drives, inside the hull. I have seen others do this, and am assuming it is not essential that the bulkhead seal the front of the hull from water, etc?

For the rudder, I wanted to add a little detail work by adding some small socket bolt heads on top of the rudder bracket. I also polished the rudder and added matching crown nuts to each side. Nothing too much, but I think it looks nice.

Nice start. I hope that it runs as well as that hull looks.

Will follow that as well - already any decisions made about the setup?

regards,
Manuel

As for setup, I have nothing planned yet. I would love to get a set of Lehners, but I know they are quite expensive. As for speed, I would like to get to the 80mph range. I am not interested in outrageous speeds. I would think that some leopard motors will work for me, but I love the look and quality of Lehners. If anyone has any motor/esc/battery/prop setup info they think would fit this hull for my intended speed goal, I would appreciate it.

Manuel had a nice setup in that hull with the TP motors and t180 esc's may I suggest you drill the holes in motor mounts for future lehners before u mount them.

Rudder Mount - Holy crap this was a pain for me. I broke 3 drill bits while drilling the 4 holes, and all 3 were stuck in 40mm thickness of the hull+epoxy fill+c fplate. The first bit to break was a small bit as I was drilling a pilot hole (mistake) and the next 2 must have been crappy bits. I was trying to go slow and take my time drilling, but they still broke. It was a nightmare getting them out, and then getting my holes aligned correctly after. I ended up with 2 holes that are not real clean, but it wont matter now. I made a new piece of cf plate for the inside for the 3M screws to butt against, and got the mount exactly how I wanted it in the end.

Drive Holes - These are next on the list, and after what happened with the rudder mount, I am real nervous to drill them. I measured for about an hour and then put a small punch mark on each side where I think I want them. I am being a little conservative and not putting them as close to the botttom pads or inside tunnel as possible, just so I have a little more room for the large nut to moung them inside and the water cooling line. Does anyone know what size bit to use for the drives? None of my bits seem to be the correct size?

I believe the standard conversion will be 15/32 if u need more info on how to mount drives please ask I definitely wil recommend using a thick template that will work for both sided just by turning it over this way they end up in the identical spot

[Chrisg81983]

Oh and in metric the bit size will be 12 mm

[nata2run]

Put a bright torch inside the hull and shine through, that way you can clealy see how much room you have. Mark it on the outside so you know you wont go past it.

[Chrisg81983]

That would work kent but I think he will have trouble doing that now that there is cf plate on the sponsons tronsom

[nata2run]

If you have the same drives as Chris, talk to him about it, as his is running real nice. Mounting drives wrong can have a really bad effect!!

[nata2run]

That would work kent but I think he will have trouble doing that now that there is cf plate on the sponsons tronsom

Umm, YES! didnt even look at that LOL
NOPE wont work

[Chrisg81983]

Yeah by the way lavigna what drives do u have ? The one nut type or the origional ones with the 4 bolt flange
