Matts Titan 40

[Mattwarner]

Time for a new build for me and managed to stubble across this hull in my LHS which i snapped up, hoping this will handle well in rougher water and i am aiming for 50mph.

setup will be as follows:
4092 1300kv to run on 6S
FC 300a 6s esc
Flooded stuffing tube

Some pics of the bare hull





There was a small amount of flex but overall the quality was much better than ive had from chinese cf cat hulls in the past however decided to reinforce anyway including the transom over the ply.

scuffed up ready for inlay



all done (still wet here)



transom hardware mounted (loosely), i am a bit worried the carbon turn fins are too small at 65mm however this is for sport running only so i will just try it and see.



motor mount came anodised orange and i am going for a clean simple look some oven cleaner and elbow grease got them stripped and polished up heres a pic after the first round of polish.

This is how i wanted it set out with the motor up front due to the flooded tube, and cells mounted on a carbon plate on top of it but i cant get it to balance right, any suggestions??

I think with batteries either behind the motor or in front proves quite difficult on cg adjustment as theirs not much room for movement of the batteries, I nearly always go with batteries either side of the motor. So theirs plenty of movement to get the cg correct, I understand though wanting to get the cg lower down & the battery weight into the centre of the boat.

I would say the same as Martin Matt, bring the motor back and run the packs either side of the motor, just to be safe with the COG
or run the motor at the rear.had the same problem on my Rico 31" the T600 helped me out being a lighter motor. sure fluid will help you with this setup.
you have mastered the carbon lining looks great.

Thanks Sam, hoping Jay will chime in as i know hes had lots of experience with this type of hull.

Ive just ordered some clear acrylic to make a sub hatch as taping this thing is going to be really tricky, iam either going to have the sub hatch fit inside the opening so that i can tape round the outside or most likely use foam round the opening and hatch bolts to hold it down.

Most of us have placed the motor to the rear with the packs between the rails ahead of the motor. This allows for relatively short power wires and keeps the build from spreading out and resembling a bowl of spaghetti. I like to put the packs between the rails in most of my builds so I can use nylon straps to hold the packs down. This really helps when you flip the boat since the packs don't move and un-plug themselves. Also keep internal damage to a minimum. We've had no problems with the CG, the packs can be slid fore and aft several inches.

I think we all just tape down the factory hatch with hockey tape. Just takes a bit of care around the transom. If you have too much overhang then a sub-hatch makes a lot of sense. Do not rely on foam for a water seal.

Thanks for everyone's input I am going to take your advuce and make up some battery trays either side of the motor and Velcro tie them down, I am limited to how far back the motor goes due to the flooded stuffing tube but should work out ok.

Great find on this CF hull !!

Got a bit more done over the weekend

Wet well drilled and mocked up

I've used carbon tube for the wet well 14mm ID and before anyone comments the transom fixings will be cut down!

Why that strut? I have never seen that used on a mono?

Good question I had it spare in my box o' bits hopefully it will work ok on a mono but agree its made for a cat

I know of several people that use struts on mono's. They also allow far greater up, and down adjustments than a stinger, lol, unless ------

I'm sure he's talking about the skeg on that particular strut. Struts are still common on mono builds.

Do you think the skeg will cause any issues?
