IM31 Tortue Testing and results - Totally Refuting any claims that 6S won't work!

Is the ABC 42x55 prop the same as a Grim Racer 42x55 (AQUB9725) prop??.

Essentially, Yes... Once prepped... I think Grim uses a different allow mixture.

Hi Darin,
How would you compare the 42x55 vs the x642 on this boat on 4S? The x642 has traditionally been my staple prop.

I use 45 mm, (M445-545) 5s battery for 4minutes no problems, only roll torque

Hi, Darin,
new turn fins
when they go to market?

Is working better than the original design, I invite you to try

The hull revolt30 and impulse31 (29 ") are almost equal, the revolt is not separated from the water, is more stable
I try revolt30, with electronics impulse31 v2 (5s and 6s) and it's amazing

Revolt30
Hi, Mike grimracer zaborowski
I think there are serious problems with the design of the rudder, the water pickup hole is very high, need 1 inch below ( the water pickup hole should be no less than one inch below the keel) very small rudder, a minimum recommended length is 1 times the diameter of its support below Lx 15% 30”x15% = 4,5” minimum. (REVOLT 30 ONLY 4")
thank you very much

Manny

Hi Darin,
so as I understand well, there's no problem with the stock electronics on 6s with stock prop.?
I have the x442, is it also OK on 6s with stock setup?
Thank you Niky.

Thank you Niky.

Fluid has given the following advice multiple times-- when I listen to it, I don't have problems... I have friends who don't listen and just burn out components.

6S is pushing it. 1800KV on 6S is almost 40K RPM. If RPMs get too high, you put undue wear on the strut bushings and on the motor bearings-- high RPM setups need to be perfectly balanced. The target RPM for a reliable setup is in the 25-35K range. Plus spike amps on 6S can take out the ESC.

If you want a RELIABLE setup on 6s, go with a 1500kv motor and 180A ESC.

X442 prop is fine on 4S for 1800KV. Actually, I would recommend x642 as long as the connectors are upgraded to 5.5mm.

I've run X442 on 2030KV and 2200KV ON 4S and have melted the solder on 5.5mm bullet connectors between the motor and ESC. My reliable setups use x440 on a mono with 2200KV, and m440 on OPC on 2030KV. My LSH on 2030KV is running a 42x55.

Hi everyone,
please, I would like to know if someone burned ESC on Imp. V2?
Some says that stock electronics is OK on 6s (Darin), other says that the 80 amp esc with 1800kv motor can't handle it.
But I didn't find on this forum any case of effective burning of esc , correct me if I'm wrong.
The people has the problems with flex cable or motor wires and connectors, but electronics no.
Thanks all, Niky.

[mannytx1]

The stock 1800KV motor and ESC 80 Amp (only 5s)

I only use 6s to test maximum speed

I want to have a boat for a long time

Thanks all, Manny

Here's a recent data point for you. See post 15,

I got this boat again. Ran it last night. The flex drive was pressed into the stuffing tube ????? Really.
Tossed it and used 1 from my revolt.
Ran fine at 35 mph on 4s. Ran it on 6s . No way. Motor was 160 degrees after 2 minutes away
