32" apparition cat help

[mattf1000]

I've just bought the above and have a slight issue I need help with. I plan to run a single 1900kv motor on 4 or 5s. The problem I have is the transom. It's not flat. It has 1.5x1" rectangle in the middle that sticks out about half an inch. How do bolt the strut assembly to it. There seems to be no room

This is the hull I have, cheers for any build advice you can offer

Most folks run twin motors on this and only the rudder is mounted on the center section. This being said there are rudder strut combos that have an offset rudder. You will have to look for one that will mount to the transom given those dimensions.

I've seen far more single motor apparitions and river cats than twins. Op see some of my build threads, will give you an idea. OSE sell the strut/rudder assy you need.

I've got the strut as above my problem, I think, is my sausage fingers and getting the nuts and washers on the bolts. There's no room down there. I'll take a photo when I'm in the garage later

Kfxguy your a hero cheers. Read your build thread and the carbon plate and riv nits is the way forward. Wish we had a forum like this in the uk

[kfxguy]

Your welcome. Look, there's a couple ways to to the nuts. They way I do it is i have a nut driver that I cut the plastic handle short and I put a little silicon in the docket to hold the nut and washer. There a better way that I saw a member here doing (srislash maybe? Please correct me if I'm wrong) it's a little three or four pronged "grabber" thing.

AstecModels is the UK FE boat forum, it is nowhere near as busy as this one as hackers took it down a couple of years ago and it hasn't really built back up, but there are still a small hardcore of experienced racers that frequent there and are happy to help out should you have problems like this.

[mattf1000]

Just a quick question. Where do you mount your motor for best best balance. I know I can adjust the cg with the batteries but what would be the best place for the motor.

[kfxguy]

Here's a couple I built to give you an idea. I can measure when I get home.

Found one more without all the stuff in it

[mattf1000]

Right another stupid question sorry. I need to sort batteries. I have a 1200w 1900kv motor and a 120a esc. I presume 5s 5000mah 30/40c batteries would the max. What prop would you recommend I have an x640 detongued and sharpened but am open to suggestions. Oh and do I go 2s and 3s. Think if buy 2 sets of each then I can get warm with 6s on occasion.

[kfxguy]

need to know exactly what motor you have.

[mattf1000]

thought i should put some pictures up not brilliant but hopefully will get better once the paintings finished
