What did you use for the non skid?
Emery cloth?

Just got back from a lake run. Still getting a TON of water through the rear hatch. I just need to silicone it down then all should be fine. What I really liked about the model was it is heavy and really needs power to get it going. It felt very realistic getting it on plane and then backing off the power. All stayed pretty cool and I'm thinking the 35 amp ESC is fine considering I normally run this motor on a 20 amp esc with no water cooling. This model is twitchy and needs to be driven the entire time. Sort of like an RC helo compared to an airplane trainer. I actually used my dual rates to slow down the turns.

Very nice my friend.
If you have ever driven a hydrofoil it is like that.
You have to fly the boat rather than just drive it.
Can it do a sliding turn in reverse?
Or would it flip.
Sounds like the key is keeping the CG low. Dave.

Thanks..


This run was at Cerritos Regional park. My bet is it would flip on a left turn and maybe not on a right. This is a narrow, top heavy boat so drive it scale.

Very nice. Wish you could have brought it to the Inland Nautical Society regatta.

Seahorse,
I used the 6-4 and just cut the blades down 5mm and balanced. As for the non-skid, just grip tape from a skateboard shop.

D, I thought about trimming down the prop, SubDave suggested it too. I may go back to the 6x4 if the new prop doesn't work out. Thanks for suggestion and for the the non-skid tape tip!, that material should hold up for a long time.

The prop I ordered has a little more girth to it:

I can tell mine is revving a bit high but also noticed the heat is down. Plan to try the APC 6x4 trimmed to compare noise..

I think I will experiment with two props back to back in a 6 blade setup.
It would look cool for sure.
Not sure if the prop adapter is big enough though.
I did this years ago in a ducted fan design but cut the blades way down for that.
The motor we are using will more than handle the two props. Dave.

D, I'll keep you posted on the Prop trials. I'm looking for a "good" tube bender, I bought a K&S bender, works nice but only on soft brass. Got any suggestions? Thanks
