Mystic 138 First Rc Boat assembly.

[sebasoakley]

Hello everyone.
Im starting to built my Mystic and its nobody on my country how know something about this boats, so please I will like to get your help and comments to built that.
My first question is the drives angle.
This angle its right or should stay more pararell to the hull bottom line?..
Sorry of my poor english, I hope you can undestand to me.
thanks very very much and best regards.

Those drives are *probably* waaaaay over sized.

[TheShaddix]

Those are the right size for this boat! Looks like a good start so far.

This drives is the ones sell MHZ for the boat so the size its right but im not sure if should be located a little bit more high for get more pararell hull bottom line. I see other Mystic drives pictures and looks more flat than mine.

Those are the right size for this boat! Looks like a good start so far.

You say good start, but that angle is crazy. I don't know much though. :/ I'm genuinely trying to learn. If something is off, now would be the time to say so.

As a startpoint your drives must be flat with the botton of the hull. Gill

These drives require holes drilled into the hull where the support towers sit in order for the locking pin to go in, that's why he can't make them "flat" yet. Now, whether or not the builder knows this I do not know! But that's how MHZ boats are due to their very low height. Ideally, the less angle you have, the better it is as long as you can keep the boat down with weight and balance.

Btw, if you still can't get the drives to be parallel with the keel, then you could cut squares out of the hull so that the tower bases will sit deeper, this way you'll get them flat.

Thanks very much every body for the comments and help. Yesterday night before to sleep I refilled the mistake holes with epoxy and CF, this morning assembly again the drives and now the angle looks perfect, now I can setting on +&- angle.
Now its moment to built the flex shafts and motor mount, please where is the right place to locate those?.
Thanks very much.
Greetings

Could be here good place to locate the motor mounts?.

Hey Sebastian, welcome to the forum, glad you went with the 138 I think you'll be happy with it. The drives look MUCH better now. Like the 138 we talked about, the 114 pedestal I modified in similar fashion and the picture shows 2-2.5mm of material was removed allowing the drives to get very very close to neutral. I'm not sure this is even necessary on your boat at this time but its nice to know you have some breathing room.

As far as the motor mounts go, hard to tell in that picture this is the 138.

Have you decided on power yet? Lot of options for the 138.

Hi Mike...your thread its very nice and very fine building. I see the web Modellbaupirat from Germany that you speaking about for, looks very good store, i'll order the lypos support there.
The motors I'll run its a TP 5660 1000kv with Swordfish 240A and Octura X457...you think will be right this props?.
Thanks very much.

[iridebikes247]

Thank you, I put a lot of time into both of them they're really nice boats to build. The MBP sled system is nice I have a lot of sets, its a little heavy but very strong and everything fits nicely.

I have run the 1000kv 56-size motor from TP. Definitely powerful with the swordfish 240. I think the 457 prop will be perfect for the hull and power system.

Big props get funny in the 3/16" size I have snapped a lot of prop shafts going with 465s red. (MBP propshafts) so the octura 457 is the way to go. I think the MHZ shafts are stronger though so you can always try in the future.

Mike thanks very much for your attention and help on this thread.
This afternoon while its arriving the motors I assembly the water cooling inlets. Them doesnt get very good fitment to the flat botom hull (first pohoto) so I pass it for the mill. After that fits much better, do you think them are located on right place?

[iridebikes247]

Also, with the drives mounted very low the bottom screw might be difficult to tighten since it likely won't sit flush with the transom. A carbon fiber transom doubler will solve this problem. Everything looks awesome so far!

[sebasoakley]

Thanks very much for your help Mike.
Today I adjust the motor mounts, using a carbon rods to be sure its straight to the drives and after that glued.
