Larrys 32" twin cat

[Diesel6401]

interested to see how she runs with that much rpm

Same here. Wanna see how those motors run. Following closely...

[LarrysDrifter]

Me too.Its 41,440rpm.I might have to get two more x442's and have them cut down to 40mm.I dont really want this to become a SAW boat,so,if it does,Ill sell the Arcs and get a couple Leopards like you are in a lesser kv,like 2650.Oh,I do have two TFL 38mmx55mm counter props from kintec that I can use too.

Sorry.Diesel is getting the Leopards,not Brushless55.Got mixed up for some reason.

Where did you get the SK120?

Don't cut them down, just get them cupped slightly, that will reduce diameter enough.... go faster too...

Your ARC's should outperform the Leopards of equal size. If kept cool, they will be fine. Guys are running these winds of motors on 5S or more in DF jets, pulling crazy watts.

I have been trying the 36-65 2080 KV in my Whiplash and I haven't got the speed I wanted but, I couldn't heat it up running a CMDI 5083 50mm 3 blade prop. That thing would have melted most other motors but, the ARC didn't flinch. Water is Ice now, no more time to test.

Ray I think he was worried about pulling too many amps with the 442's. Cupping them will make matters worse as this loads the motors more.

Got them this past spring from WWW.hobbyhot.com

[blackcat26]

Please be carefull on the AMOUNT of either 2 part pour in foam or the can spray in foam for
flotation.
I have seen in the past where a bit too much has been put in and the foam EXPANDED more
in the hot weather and actually caused the deck to split.

Moving Ahead

The 1st pic is a mock up of the stuffing tube and tube support.The motor isnt mounted yet,just set in place for alignment.The stuffing tube support did get trimmed down in case you wondering about the big square.
I also made bushings for the motor end of the stuffing tubes to center the wire.These arent glued in,just slid in place.The stuffing tube is 7/32,so if I want to ever run flexes I can use .150's with no teflon.The bushings also keep water from coming up the tube.

[LarrysDrifter]

This one shows how I suck at drilling holes.(Or just getting the alignment right for the holes).The right side came out much better.

[LarrysDrifter]

Here is where the stuffing tubes will go.Got them tacked in with CA untill I get them epoxyed in.Also trimmed the stuffing tubes supports.For me,this was the hardest part.Its all down hill from here.My next build might be an ice breaker so I can test the twin FighterCat out.
