18.5" mystic build

[befu]

Wow,, thaught everyone was gonna take um, so what glue do you use to glue them together, epoxy doesnt seem to work well on a hydro im doing so dont wanna use it on the cat...

My experience: I use model cement since it is a styrene base plastic. I use the MEK liquid type, just a brush, hold together for a half minute, then move on to the next section.

I do the back transom first so it is secure. Before gluing, setup the hull and hold the sides into place with a couple pieces of masking tape first, keeps the hull from shifting around. Then I do the fronts of the sponsons. After that, just move around the hull and from side to side to keep it all straight.

the one and only I did turned out really well. Then I filled it with two part foam, but I did it in multiple pours and it was too warm. Didn't wait between pours and it deformed all over on me! So I threw that one out.

The next one, I am going to reinforce the hull before joining it together. Scuff up the inside surface and glue in some real light glass to give it some strength. CA and glass might work well on a boat this size. You need to scuff up the surface first.

I have also heard of some epoxies that are plastic compatible, they must etch into the surface some. That would be helpful. The CA I use doesn't touch it and it will pull right off.

You going with a single or twin?

Small, isn't it. After putting one together, I have new respect for the guys making twin 14" and 16" cats!

Thanks for the info im going single, i dont think i could do dual having only made a few boats i think im not ready to try a dual setup yet...Not unless i can do it really cheap i already have stuff i was going to use on a mini-c but going to put in this hull if it will all work..

hi befu, i was wondering if you would sell me one of the hulls you made before the mold broke. it doesn't really matter if it had perfect crisp edges or anything. i live in Il so i was wondering if you could ship it. i would pay for the hull plus the shipping. this looks perfect for the guts from my mini v. the mini v is too overpowered. so this 18" would be perfect. i mean PERFECT. please sell me one!!!!!!!!!

[pepperson4]

oh and it doesnt really matter if the halves are joined or not. i might pay more if they are though:). i was also going to put my 2835 2700kv motor and x430 prop and ose stru into a mini c, but this looks so much cooler and sleeker, and its also bigger which is good.

[HYDROJERRY]

im doing the same,, well when i get time to start it..

[pepperson4]

well if befu does sell me one, then i guess two heads working on the same thing will make things go a little smooother!

[HYDROJERRY]

I hear ya but i have 2 other builds before it so i will probly be watching yours and asking YOU questions,hehehe.

Sorry pepperson i tried to look but my computer doesnt want to pull up a second page ill try at work tomorrow.
Heres some pics of what ive done so far,,looks like crap but it should work..

[pepperson4]

looks good that should add a lot of strenght to help at higher speeds.

What weight glass did you use? That fabric doesn't even look like it's wetted out...

[HYDROJERRY]

Dont no the weight but its as thin as silk,,that picture i had epoxy on the hull layed the FG, but last night i mixed epoxy and some acitone and went over it again ,put some fine slices in the bubble areas to get it all in there..

Well, my 2632-3000kv mystery outrunner showed up today, so my 8 year old is prancing wanting to build a cat after his crackerbox. Started trimming a hull up and I just do not know.

I fixed the vacuum form mold, but still not happy with it as I have posted. I am in the process of filling the vacuum ports with clay so I can try to pull a fiberglass plug. I am thinking a hull laid up from 3oz glass and carbon fiber tissue would be way ahead over the vacuum formed one. I am also waiting to see how jerry does on his.

That 2632 sure looks little in that cat, but I think it will push it nicely. twins would definately work, but want a more conservative setup for the 8 year old.

Good to here from ya again befu, sorry didnt mean to take over your thread hope its ok..Just an update i had a crease in the side of mine from shipping so when i cut out the top opening i cut some strips to use to strighten the side that was creased, went ahead and put one on the other side too, heres some picks of my layup just sitting in there to show,,remember this is the stuff i got for my mini-c but this hulls bigger and cooler...,,,Think im going to paint the inside, do you guys think i should get my motor and servo mounts in first or will it all glue to the paint just as well...
