"Q" Outboard tunnel discussion. 6S motors and ESC's?

[kendt]

My first set up using smaller prop and high rpm,s . So far i am super impressed.Got to be very gentle with the trigger though or it will wheelie like nobody,s business.The acceleration is amazing.

[er8sr]

What kv is that motor and what prop you using?

[kendt]

1900kv with a tfl 442 trimmed to 40mm

[er8sr]

I finally got around to building me a vs1 with a k&b lower and a scorpion 4025 outrunner, I have ran it on a 4s fixing to go to 6s as soon my new seakings get here

er8sr,
What kv are you using? I have run a 4020 1350kv Hyperion/Scorpion on a .45 size nitro hull with an m445 prop on 6S. Just short of 50mph. Your 4025 is a tad stronger and will be a handful on your VS1. A rocket for sure.

Sorry it is 4020 1390 kv out runner. Will be testing 6s hopefully thursday

[HTVboats]

How did it run?

[er8sr]

Runs really good motor is nice and cool. Plenty fast going to gps it and play with props tomorrow

[er8sr]

Still playing around with motors I threw a Align 500mx motor on 1600kv a worn out 6s 4000 pack gps' d it @ 49.8 propped with 440

Boat is very effecient and fun to run I get a solid 5 minutes...

I did not have a good season with mine. The 7.5 outboard is too big, so for next season I will switch to the 3.5. I also had a ridiculous amount of trouble with esc,s so I didn't get a lot of running with it at all.

[er8sr]

Sorry to hear that, I tried my luck @ waterprooing a esc it worked really well till i flipped it and kept running then it went dead about 2 minutes later,I got another HS 45 with a K&B 7.5 lower i have a feeling it is way tio big Here is a pic of the VS1 wiht the Align motor and K&b lower

[kendt]

Ya the 7.5 is def too big. I had one so I thought i.d try. I tried a scorpion 3226 and found it was too small. Got fairly warm even with smallish props. The dr mad thrust 3674 1580kv looks like a good match but I was unable to get any real solid run times or try many props cause my t180 kept going into lvc. was unable to get it resolved. What kind of wattage does the align handle?

[HTVboats]

er8sr, Actually your picture is an OS lower which is the best of all. Your speed and run time are excellent.
Kendt a 3674/1580 on 6s should do very well. A Grim racer 42X55 or M440 on the low end and you should be able to handle an m445 on the big end.

Iam Sorry. OS lower. ... I keep saying and Thinking K&B. Iam Very Very happy with the setup

[er8sr]

Kendt here you go
The 500MX is rated a 1600 W max, and 2300 W (5 Sec burst). If 1 Watt = 0.00134 HP, then the 500MX is about 2.15 HP.

[er8sr]

I have all he way up to a 445 prop to test but I lost my esc.. So waiting on a shipment from hobby wing

[er8sr]

Got her back on the water after a few tweaks got it running a solid 52.6 mph.. Boat is handling Great iam very happy...
Ended up with a Seaking 120 works flawless
