Sport 40

Job well done! Is that a Prather 225s or 230s?

[andym]

It is the 230s Chuck, nice spotting! Thinned to within an inch of its life and just a hint of edge cup. Should rip on 8s with a the 1050kv feigao 580 xl.

That is one very HOT looking boat Andy, VERY nice

Well an update is in order, first run with Hyperon 4s 35c x 2 packs in serieies for 8s, CC Hydra HV 240 and the Feigao 580l 1050Kv motor. Ran hard but a bit wet, heat OK changed T/Fin angle and lifted strut to 16mm from 20mm. Boat launched hard , turned even better and was well over 60mph.
They are an impressive sight at full flight.
Came back in and checked temps, esc & packs OK motor a bit warm. Changed to a x447/3 blader , what a blast , out of the hole like lightening and very quick.
Then BANG one CC HV 240 up in flames!! No damage to anything so I consider myself lucky.
Back to CC with this one
If any of you high volt guy's would care to share your motor, esc and prop set ups I would appreciate it very much as this is my first HV application.

Sorry to hear that Andy. It has not been a good year for you.

Bummer Andy - sounds like the 447/3 may have been to much prop?

[Fluid]

The x447/3 is a HUGE step up from the the P230, with 33% more blade area and load, but with LESS pitch (2.6" versus 3.0") so a lower speed potential. Perhaps a better step up for more speed would have been an P235. More pitch makes the boat faster, more blade area can increase acceleration but limit top speed.

It was Faster with the 447/3, no question. I can run one on my 4s mono over race distance with similar total rpm so I assumed that with the higher volts and lower KV it would be Ok. The old pitch versus blade area thing,,,,,,,,,,,,, I have more fun with larger props with less pitch as they get out of the hole better off a turn and due to the size seem to stay hooked up in chop better.i have found the amp draw between say a m645 and a m447 similar but the 447 a better all round prop.
I do not think it would have been over 180 amps as the packs were not even warm

[crabstick]

always sad to hear of an esc going

Specially when it really shouldn't.

Are you going to get another Castle ?

[andym]

Only if they replace it under warranty, I got it off of TTH (Tracy Hatch) it was brand new purchased by him and forwarded to me.

Probably your ESC did not burn because of the high amps but because of the wire inductance. This is helpful

What I understood is
a) As short wires as possible from bats to ESC (max.12" total)
b) Close the positive-negative wires loop by attaching the ESC wires together.

Sorry to hear your loss, but they say that CC is good in replacing ESCs

[andym]

The wire length is as follows, battery to esc 105mm, esc to motor 50mm. 5.5 bullet conectors. Packs, + to neg and then + esc, neg esc to series the cells. I have been doing this hobby for some time and the only CC esc to *!***!***!***!** itself is the CC120. Just a poor esc the 240,s I have are great and I was hoping all the negative reports on the HV 240 were user error but I gues not. Should have got a Shultz!!!!!!

[jingalls007]

I would think with a HV setup 8mm bullets might help to carry some of that current. I think 5.5mm bullets are to small for that power.

Yea, I thought like that too. After burning through a bunch of Hydras I finally got my new 40/160 running last Sunday. Should have listened to experienced guys over here who told me to get Shulze right away, back when I was experimenting with cheap Chinese controllers. I must have burned through over a grand. Could have had two 40/160s with that money I wasted.

[andym]

Yes I must agree, where are the experianced HV guys? Any imput is greatly appreciated.
