MHZ Racemaster ~SINISTER~

[gixx1k2]

Building a MHZ Racemaster mono over the winter, going with the name SINISTER. For power she will be getting a Lehner 2280 with KBB spec 300A lite ESC, rudder and drive are MTC, and speedmaster billet trim tabs. First step is the inlay, I've yet to do one myself so I will be heading to Shawns (Apophis) for a lesson :thumbup: I will be taking all hardware in to be anodized black to get the look I'm after.

[Tamelesstgr]

Those are some stout looking parts! Is there all ready one layer on inlay in the hull?

[gixx1k2]

No inlay yet I ordered the Kevlar version from MHZ

[iridebikes247]

Nice, with that motor should be good for like 35-40 mph right? :laugh:

Curious what will cell count be? Hardware looks great too, that MBP jacket is really cool.

[gixx1k2]

Lol yeah she should hit 35-40 pretty easily. Will be running 8s, I've never used the MBP jackets before but I like the way they look.

[srislash]

I like theses hulls. Going to be a fun one for sure.

It's a cool hull, a little narrow but I like it as well. I'll be getting started on it after Christmas

[kfxguy]

This ought to be a nice build!

[gixx1k2]

Made the trip to Shawns (Apophis) house today to get a lesson on inlays. I learned a lot, and will attempt to do my own inlays on future builds. Shawn did a great job on it, and we also got the transom doubler made as well.

[gixx1k2]

Got a little work done today, I trimmed the excess carbon from the hatch, installed the transom doubler, and filled the bow with 2 party marine foam. Will start drilling some holes this week.

[gixx1k2]

Had a little time before work so I got the motor mount mocked in place, drilled the stuffing tube hole, and got the tube bent. Fits like a glove :banana:

[gixx1k2]

Also does anyone have any ideas on how to fill the void between the rear motor support and the bottom of the boat? I have like a 1.5" gap

[gixx1k2]

Got the stuffing tube installed yesterday, today I'm getting the motor mount epoxied in and the stuffing tube brace is also getting installed.

[gixx1k2]

Got the rear motor support bracket mocked up. Will be getting it glued in tomorrow :thumbup1:

[Shar75]

Ideally!

[gixx1k2]

Got some hardware mounted up today, also got the rear motor support glued in place. Might swap the turn fins for something a little smaller

She looks awesome! Keep up the good work!

Thanks man :cool2:

[Roy Van De Sande]

How long do you let your epoxy dry before removing the tape around the motormount ?

Thanks,
Roy

[gixx1k2]

Usually over an hour, I just keep checking on it to see if it is tacky enough to hold its form

[Apophis]

Looking good bud, you going someplace warm soon? Going to be a long time staring at her on the self till that crunchy stuff goes away lol. Guess Flint is only 17 weeks away :olleyes:

[gixx1k2]

Lol I know, I plan on winning the powerball tonight so I'll be headed south till spring. :biggrin:

[Apophis]

Just buy us a private lake with a few houses on it. Weekly SAW events, I'll be your pit guy and wash your Lambo :hug1:

[gixx1k2]

Lol Sounds good to me

[gixx1k2]

Just got my rudder stand off back, I had a buddy machine a spacer for me :thumbup1: I'll be getting started on the steering this weekend

[Roy Van De Sande]

Looks size! What is the kv on the lehner?

[gixx1k2]

It's 1233KV (loaded)

[ls1fst98]

Looking good!

[dasboata]

Looks great the inlay came out really nice !!! that's not easy to do nice and dry like that !:thumbup:

[Roy Van De Sande]

According to the lehner motor calculator, the maximum efficiency on 6s is around 161A and on 8s around 201A.
Are you going to run 1p or 2p?

[gixx1k2]

8s1p by 2-4s in series.

[gixx1k2]

I have Apophis to thank for that. I've never done one, so I took it to Shawn for a lesson from a pro :biggrin: I just picked up a DF sniper I'll be attempting my first inlay on that when I get around to building it.

[gixx1k2]

Got a little more work done today. i ordered an esc mount from MBP but needed a CF plate to be able to mount it, I don't have any laying around that's big enough so I decided to use a old CF battery tray. Looks like it will work well :thumbup1: I also got the rudder mounted and water inlet installed.

[iridebikes247]

That's one intimidating looking mono :rockon2:

[gixx1k2]

That's one intimidating looking mono :rockon2:

I just hope it performs, it's a narrow hull with lots of power. Hoping to be able to keep her straight :thumbup:

[gixx1k2]

Had some unexpected time today to mess around with the mono. I got the steering linkage installed, I'm using a carbon fiber rod so I need to get the servo arm aligned perfectly. Also got the water outlet and antenna mount installed.. I got the hatch bolts installed tonight as well
Next weekend I'll be working on getting the servo mounted just gotta figure out how lol

[gixx1k2]

Using a carbon fiber steering rod obviously cannot be bent, and I didn't want to put a shelf in and cover up easy access to the transom hardware. I found a servo arm from an airplane website that is perfect length so I can still use the mount I have, and get perfect alignment with the linkage :thumbup: I'll be getting the servo mounted permanently tonight.

Excellent servo choice. My Radiopost servo is fantastic. Great looking build!

Thanks for the compliment, these radiopost servos are awesome. I like how quiet they are, can't even tell they're on

[iridebikes247]

Nice job again. That stuffing tube mount is sick too the maiden is going to be a real experience.

Can't wait for the ice to melt :glare: the maiden should be interesting, I'm worried there will be to much torque roll with how narrow this hull is. May have to shim the drive a little

[gixx1k2]

Just got the hull tore down and dropped off at the paint shop, should have her back in a week or 2. :thumbup:

[gixx1k2]

Went to my buddy's to pick up the boat today :banana: now just need to reassemble her

[Fast One]

Hi, I read at the start of the post that you would be getting your hardware done in black. I to go with that colour and it comes up great. The only thing I wanted to let you now was that with the trim tabs you have from speed master I could not get the stainless hinge pin out?.
I tried heating it, drilling it and hammering it. Not sure how they assemble them but it seems they must have a thread machined on one end and then the screw head must wind off during manufacturing.
Has anyone else tried to pull them appart successfully?.

Thanks Shane.

[gixx1k2]

I think it would look awesome black but Ive decided to leave it alone. Next time I will order the hardware which is already anodized

[gixx1k2]

got her all back together and ran the water lines. She's ready to go soon as the ice melts.

[Tamelesstgr]

Looks fantastic, love the paint colors, really pop. What about adding a little bit of silver trim for a window?

Thanks, I'm waiting on a windshield from monojeff :thumbup1:

[gixx1k2]

Finally got her in the water. I got a bit of tuning to do, but was happy with the maiden overall (besides the flex snapped at the end) Haven't quite figured out why it happened, driveline spun freely before the run. I'll have her back together and hope for some nice weather for the weekend.

Did you glue or solder the flexshaft?

[gixx1k2]

Did you glue or solder the flexshaft?

I use LocTite 648. It snapped about 2 inches from the motor collet inside the stuffing tube
