That'll be my next build hull. Was it hard drilling the drive-line hole?

Drilling the stuffing tube hole thru the tunnel bottom isnt that hard on a single set up. First intall the strut and the motor mount. Then install the motor and collet. Insert about a two inch of 3/16 brass tube in the collet and trim/position it so it touches the tunnel floor (you may have to pull the motor or collet off serveral times till you get the right length of tubing). You now have your spot for the stuffing tube hole. Get a Dremel with a carbide cutter (9903) and slowly grind untill you can fit a 1/4 inch suffing tube in the hole and up the 3/16 brass tube. The Dremel makes a much cleaner cut than a drill. Once your stuffing tube is bent and ready to be glued/glassed in, leave the 3/16 tubing in the collet while you install it to ensure good alignment with the motor.

If your motor is more parallel to the tunnel floor like the one pictured below, you will need a S-bend in the stuffing tube. In this case I put the stuffing tube hole on the 32 as far back as possible to keep the S bend in the center of the tube (as much as possible). This leaves me straight runs on both ends for cable alignment and adjustment. I still use the 3/16 tube in the collet for alignment when glassing it in.

I know of 4S setups that'll do 65mph.

Yeah but on a 2150 kv motor?

Chilli what hyperion rx pack do you have in the pic. Thanks.

not a tacon, but the Aqua 2030 can do it.

Lol.. Come on, now. One guy did it. One time. For a saw pass with a big finely tuned prop. With a hydro. Not the same..

[mtbenjamin77]

It's been done in a cat, sport hydro, tunnel and outrigger hydro all P class and that's just the namba records. Top speed for the outrigger hydro was 80+

[mtbenjamin77]

in fact, every record held in the IMPBA P class saw is over 65mph

[Heaving Earth]

Seriously. I would hardly call it a 65mph 4s setup for gereral use

Devo's post stated it was a "saw run" so I am comparing it to a saw record.

Hyperion 850 mah 2s LiFe

What is the run time you can expect before needing to be charged on an 850mah Life.

[Heaving Earth]

You got a point there.

Just some more P class record information. All of the info posted above was for P Limited. The record for P Offshore is 93mph and was achieved in the exact same hull Devo runs, the FC 32. So Devo's got a ways to go to set any national records, oh and he's running Q voltage which the record is at 102.041. All this SAW talk makes me want to build a true SAW boat. maybe P Hydro?

I have done a half dozen 5 minute runs without recharging. I havent pushed it any more than that. For my gas boat running two servo's I use a 1700 mah pack.

It was a little smoother out today and it went a little faster on 6s, im so impressed with these Tacon 2150kv motors that I think im gonna put a pair in my new fantasm. 67.4 mph on 6s
