Hobbyking Libero mods

[Old School]

For a bit more to get me more deeply interested in fast electrics I have purchased a Hobbyking Libero shovelnose. As I await its arrival I need to sort out a few details.

Firstly, this is the ESC I hope to use as I want to use this type of ESC on a current 70 cm mono project and wanted commonality.

Secondly, being overly cautious, I wanted a dual pickup rudder, however, after trawling through over 700 rudders on eBay the only dual pickup rudders available have a different pivot mechanism and so a direct replacement rudder to the existing hardware is apparently not possible. Any thoughts please. I could opt for a through hull pickup as an option. I wanted separate motor/esc cooling paths.

Edit: I found this rudder at RC Boat Bitz. This looks like it could be modified to fit or might be direct install. It is 100 mm deep. I could trim a little from the lower edge if too deep. I am only looking at the rudder itself and not the rudder arm mount bracket.

I have one if those boats and I love it. I put a turnigy 120 amp esc and a x442 prop. It runs pretty darn good on 4s but is a beast on 6s

Many thanks. The X442 is now on the "to do list". I think at my age the 4S may be all the excitement that I can handle.

if you want to save some dollars, buy the 95 mm long rudder assembly from hobby king for about $10 and also buy a piece of 3/16 o.d. brass tube that you will mount on the back of strut behind and above prop [ hobby supplies melbourne ] have this cheap kit. this will give the extra water cooling so you can buy the single pick up rudder which is alot cheaper than those double from boat bitz.

3 or 4 years ago i bought a hull and put a TP motor in it.

goes very well, what size motor and esc did you use in this hull ?

I have been flying since 2015 and would not be able to remember what is inside had I not written down the set up on YouTube.
Here is the copied/pasted description:
"This is not a new addition to my fleet, but I wanted to try a CNC prop. The CNC prop (4216) is a 42mm 1.6 pitched prop but with de-tongued feature. It is more DT'ed than the m series prop. TP Power motor 3630 10D ( 2100kv), Seaking 120A ESC V2."
I liked this CNC prop the best.

The three blade prop was for photo only. But I do believe it is also a 42mm prop.
As you see, the rudder worked really well and with this setup (4s) there was no heat build-up issue and one water pickup is plenty.
The ESC is an earlier Seaking and Turnigy also has a twin. I believe now these marine ESC has moved to at least V3 as shown by the OP.

Thanks, very nice little hydro.

Thanks, very nice little hydro.

Thanks, I always wanted to buy the one from HobbyKing, but then Ron1950 sold the bare hull to me.

[Old School]

That is nice. I had intended leaving basically stock (apart from a larger prop), however, you have inspired me.

[rol243]

well Old School you know what size motor and esc works well in this hydro now.

My ESC arrived today by DHL on a public holiday. Surprisingly, the ESC was delivered from Hong Kong, while I am still awaiting a delivery from the Hobbyking wharehouse just three hours drive from me. The Turnigy Marine 120 amp looks identical to the Hobbywing Seaking 120 amp, including the programming box connection pins. The item appears cosmetically very well built. It will be sometime before I get to check the internal electronics for quality.

The overall dimensions given on the website are a little misleading as I assumed the dimensions were the case dimensions, whereas the length is that of the brass nipples, almost 1 cm longer than the case overall and the width several millimetres less.

these are quite a good esc especially for the price. oh have fun inspecting internal componants in this esc as its a sealed unit other that a couple of external capacitors. lol.
