That's looking REALLY good.

Thank you, Oliver included a copy of your translated instruction with the hulls and it’s a huge help.

I glued the mount in the hull and making plans for diffuser, I made a quick foam mold for the carbon cover and need to come up with something for the vertical fences now.

You're most welcome. I was hoping he would include those when shipping the DM to customers in English-speaking countries. Honestly, I didn't know if he would (printed and/or downloadable version), but I'm glad he is. If even one person is helped by my German-to-English translation, I feel those weeks translating it was well-worth the effort.

I finished the outside good enough for now, I copied a German boat builder for the skates and I will test these on this hull.

I checked the linkage and I’ll start making the parts for the inside to mount motor and servo before I finish the outside.

I have never tried it so could be wrong, but I think that although it will reduce drag, the downforce aft of the transom from a diffuser would be the last thing I wanted on a cat.

I don’t know what it will do but now was the time to upsweep the rear if I wanted to find out, it will be easy to add some material to reduce the up sweep later if it creates an issue.
I’m asking lots of questions on other sites but only getting sporadic answers and I have zero experience myself so I rely heavily on the advice from people like yourself that have paved the road for the rest of us.
Do you think I should make changes now or put it on the water and see what happens?

FYI these are the two boats I looked at for inspiration.
This boat is said to run well and the diffuser from what I understand was a big help.

This is the Drifter in Germany and he is running 130+KPH that I was trying to duplicate, I made mine as close as I could from the photos with the exception of the upsweep creating a diffuser.

This is his second boat.

That's a Bulgarian cat modified by Mike W. The videos of it running triple digits are impressive.

Do you have links to the videos?

Wow when you said impressive that might have been understated, that boat is a work of art in photos and the video is even better.

Thank you for sharing!

Run it for sure, there is no science without testing your hypothesis.

Just because I think it will be bad, doesn't mean it will be, I have built some really terrible boats that I thought would be fantastic. Trying things out is the key to improvement, maybe at the start half your ideas are good and half are bad, but if you test them all out you find out which are which, apply the hits and drop the misses to improve your boat, and learn from both the successes and the failures, with that learned knowledge the percentage of hits to misses will increase.

I agree with the "you'll never know unless you try" theory. For Scale Nationals this year, I custom-built a Class 3 crawler that I considered to be a 'Capra', purely because it still used the Axial Capra cage, as well as a 3D-printed skid designed for the Capra...but, no other parts were from Axial, nor were any other parts designed for the Capra.

Knowing that the Capra was too tall, and had to high a CoG, to be 'comparative', I thought that, by custom-building my own rig, based on the Capra cage, I could build a truly comparative Capra-based vehicle. I still used portal axles...but, I used a variety of brass & machined aluminum parts to give it a much lower CoG. To make a long story short, some of my ideas proved to be extremely good...and, some weren't so good (of the 49 Class 3 rigs, I placed 37th...not too bad for my first time at Nationals). But, had I not actually tried all my ideas together, I wouldn't have found out which were 'good'to and which were 'bad'.

On a quick "side note", those 'good' ideas are now making their way into my new Class 3 comp rig, while some of the 'bad' ones are being "modified" for potential future use.

Trying to get everything set before I glue the titanium sleeve in the hull, this is the first time I’ve attempted going through the bottom of the hull and now I’m second guessing myself.

[NativePaul]

That is quit a lot of bend for a wire, if there is anything you can do to get the motor lower down and/or further forward it will increase your reliability.

[J Mack]

Thank you Paul, I ordered some .098 cable but ETTI is the only place I could fine the 4mm shaft and they take 5 weeks to deliver.
Do you see any reason I couldn’t glue the sleeve in the hull and just run a stuffing tube through the sleeve later?
