Minicat Racing Tenshock Mini Eco

[sailr]

Rob,

Yes, you have a 3200KV motor. Stay with 3S! 4S is too much for the 3200.

You can add weight to achieve the COG. Where did you buy your Mini ECO? Your profile does not show what country you are from. If you bought from us, you would have gotten instructions with a photo showing where the COG should be. If you are going to need to add weight, put it in the port side corner of the stern. This will also help the boat self right more quickly.

Just checked, and it's black on both ends - so I do have 3200kv? Ok I'll think I'll stick with 3s in that case.!

Is it ok to add weight to the stern to get the cofg right? Should this be at 30%?

Thanks!

Rob

Tenshock has informed me that they will NOT be putting 4200KV motors in any of their mini series boats...only 3200KV or less. You may have gotten one before they made that decision. Hard to say since you didn't get it from us.

Just to let you know

Tenshock have a new 2009 model out, that runs a 4200kv and 40 Amp esc
I should have my new one arrive next week.

Hi sailr - I'm in the UK not US, got mine from Astec (see earlier post). Thanks for your advice, hoping to test run again this weekend with 3s battery and weight added to the rear/left side. Will let you know how it goes.

Got my eco today. She is a beauty! Flawless gelcoat. Awesome hardware. Stainless prop and rudder. Mr. Sailr included a programming card with the 35 amp Seaking esc. Also even hooked me up with a nice roll of hatch tape. He even includes a female deans for your battery if you need it! Placed the battery and it took a bit, but I got it so that it self rights in about 4 seconds. First run reports will be tomorrow. I have 2 Flightmax 3s 20c 1500 packs charged up and ready to go! Should be a balmy 35 degrees tomorrow!

So why did you sell the ECO if you liked it so much on the Rumrunner site?

I sold it here on OSE. Bustit sold it on RRR. I sold it because I cant hold onto anything. Don't even remember, it was prob to fund other boat parts. It is a super fun little boat though with top notch gear!

[v-spec]

If these were a little cheaper I'd get one, I never got to run my H&M eco with neu motor before I sold it. Lots of us on here seem to build stuff then sell it, what's up with that! I wonder if Sailr has any with no electronics? I've got some 3 s lipo's and seaking 35 amp esc waiting on something or other..

Just bought a yellow one and having issues getting it to self right, any suggestions or pictures of setups would be helpful.

Thanks

I added a few more holes in the top deck near the bow in the flood chamber and a teeny bit of lead inside the chamber itself. Add it in the rear, in the chamber on the outside wall. depending on your pack, you can put it on it's side all the way on the port side. My righted in just a few seconds.

Thanks I'll give it a try.

I would like to get my hands on about 8 of the 3200kv boats, and start a class this season!

Our club runs six MINICAT HYDROS with stock motors, x430 props, 2200 3 s lipos, OSE micro turn fins and we are having a blast. The enjoyment comes from everyone having the exact same equipment bringing driver skill to the forefront. We have found the boats to be very durable and well worth the money. Don't worry SKIPSTER, I have one for you. BG

The secret is to get the left side of the boat to sink quickly. The boats are shipped with minimal venting/cutting to leave that up to the user. Any cutting you do to allow the side to sink quickly must be done on the deck, not the bottom of the hull. In addition to or in lieu of lead weights, you can also use a heavier battery pack. I used a small 3000mah pack, mounted on it's edge, up against the flood chamber bulkhead.

For those that are struggling to get their CoG back far enough, there is a very simple way to get it back further, the rudder linkage is what limits how far back you can move the battery.

All you have to do is:-
cut the ziptie holding the servo in,
run a long scalpel or stanley knife blade through the servo tape between the servo and mount,
remove the servo arm,
remove the servo,
clean residue of servo tape off servo and mount with a scrapeing action and IPA,
remove the rudder and file a new flat spot into the top of the shaft at 180 degrees to the original one,
shorten the linkage until the 2 plastic ends are nearly touching each other,
reinstall rudder with grub screw against new flat spot,
reinstall servo the other way round to how it came out with either servo tape and zip tie or glue,
smile as you slide the battery along the flood chamber wall right to the back of the hull!

God alone knows why they install the servo and servo mount the wrong way round at the factory.


Caution, the colour of the motor is not a surefire way of telling the KV as Sailr says the 2600KV is light blue, but so is my 4200KV.

As Sailr mentioned flood chamber venting, i just had to brag on my electrical symbol vents
From bow to stern:-
Danger high voltage.
Ohm symbol,
Caution electric shock risk,
Electrical hazzard,
Resistor symbol,
2 cell battery symbol.
Brushless motor symbol,
Earth symbol.
