Sorry, wrong film. Should have been The Cruel Sea.

the way i drive airboats reverse might be a a necessity! But as the asdic instructor said in Sink the Bismark, all it takes is practice, lots of lovely practice.

Very good Chris,
Hope you ordered the Programmer as well. Saves a lot of beeping around😉

Must admit I also wondered about reverse!
Airboats I have seen, models and real ones in Florida, all seem to reverse course by doing skidding U-turns. S'pose it might help you to back out of the reeds though.

More ideas later. Gotta go and get fed by Gisela now. 😋😊
Cheers, Doug 😎

Hi Chris, You may not want reverse, as unless you have a way of locking the prop onto the shaft, it will undo the prop nut and throw the prop when in reverse. Could be dangerous !

Thanks Doug for the speedy reply. ESC on order!

Hi Chris,
Best data I can find is this-

"Prop Test Data MX2212-920KV
Voltage(V) Propeller
(inch) Throttle Current (A) Watts(W) Thrust(G) RPM
(RPM/Min) Efficiency (G/W)
11.1 APC 9X6 SF 85% 11.2 115 470 6150 4.09
APC 10X4.7 85% 11.3 120 680 6100 5.67
GP 10X4.5 90% 10.5 116 685 5763 5.91"
That's exactly as I found it here-

Looks like they tried to import a chunk of a spreadsheet page into their doc🤔
Most Apps / Spreadsheets / Websites will turn it into pure text, UNLESS you insert it as an image😉
Motor seems to be intended for a quad copter/drone.
As far as I can make out the max current at ca 85 -90% throttle is around 11A on a 3S LiPo.
No data on stall current, but I guess you don't get much pondweed at 200feet 😁
No data for 100% throttle either - so leave the lead boots at home!
Still it gives you some idea about what size prop to use on your airboat.
So any reversible 20A+
My goto BL ESC for up to 30A (180A peak) is the Hobbywing QUICRUN 16BL30, very reliable and efficient, will give you bags of safety margin as well.
I get mine from Krick here in Germany,

but if you Google some UK sources should pop up.
User manual attached. There is also a Programming Card available which simplifies the setup enormously.
Have fun.
Happy boating ... er flying ... er floating ... er ... Aw shucks🤕
Cheers, Doug 😎
