I started filling what I thought was gel coat and found this. It is 33” x 13 1/2”
Looking for setup info

Thank you. Can give me any setup knowledge it has been 20 years since I ran a tunnel.

James, To start just keep it simple.. put on an Octura X448 and have the bottom of the bullet at water level to start.

Set the CG at 27%

Keep the fuel tank as high as you can under the cowl.

Put more servo power then you expect you might need on the steering.

No need to go nuts on the Nitro for now..

Test and tune.. replete! Ya got this!

I knew a few people that ran these and they ran pretty darn good!

What servo would you recommend? I am building a new radio box. I plan on using brass tube for my steering rods

James,

Speed.. not an issue.. power AND durability is the key. Let me look in my box of servos. I think I have some 1/5th scale servos and can let one of those go.. (need to check that!)

I have servos. I was more looking for torque spec. I want to optimize the radio box. I am working on K&B and Nova Rossi 46 setup.

OK.. very good.. 350oz-in PLUS! you cannot put enough power in the boat.
