hehe NICE!
4325 will pull it great.
4330 will pull it better,may even balance it a bit better too.
5330 will too (I think overkill but what do I know) Balance I've heard it balances fine with it.

is it correct that the 43xx motors can be wound for 8s or 6s? and that the 53xx has only been used for 8s?

I really like my 4330 setup a lot.

Perfect combo of power and weight IMO.

I think the 4330 will be really sweet in my 71", I just have to put a new motorbox on it.

I went out and bought a 20x10 after SteveT reported success with his 295kv hacker on 8S. Maybe the 5320-300kv will turn it, maybe it won't.

I just want my 72" extra .

Oh.. it will turn it...what ESC do you have and what batts...mine was pulling over 3kW on that prop and over 100 amps so i cut back to a 20 x 8 for fear of the 100 amp ESC...

It's great to see other poeple using those the Anti spark bulltet connectors. I just put some on my helis and they work perfectly. No more spark to ruin my dean connectors.

I love them too. On my 89, I have that bullet in the series "jumper" wire between the two packs.

I've got a set but have never used them...wondered if they were proven. I guess so.

just looked and I found them...open scattered, and I can only find one of the female connectors with the soldered stuff on it.

Edit, looks like I have whats in the kit, 2 male, 1 female, 1 female with electronics on it. But have no idea how to wire it. I run 8s.

Tomorrow, I'll post a pic of my series adapter I made with them.

On my helis (and what it sounds like Moose did) I put the anti spark connector in between the deans connectors. Take a look at the pic on this page. http://www3.towerhobbies.com/cgi-bin...?&I=LXYHX5&P=7

There is a black wire connecting both of the male deans. You would split this wire in half and solder the anti spark bullet there. So you would plug in your batteries first, then finish the circuit with the bullet. The deans connectors never see the spark so they no longer get damaged.

3k watts! Now I'm scared. I bought a castle 100A along with the plane and intend to run on 8S. Sounds like I will be pushing it. The castle is rated max 8S I think.

Got a good deal on the anti spark connectors because someone bought 5 too many by mistake . Figured I could use it. It's apparently a resistor stuck on the end of the female connector. Good to know it works!

Yeah...I got an ICE 100 "heavy" (with the heat sink rated for 8S) with the 20 x 8 Xoar PJN on 30C 8S 4000... I'm pulling around 88 amps and getting around 2600 watts...That is plenty of power for the 72...I wanted to try the 20 x10 (to be ludicrous...LOL !!! ) and the motor didn't seem to mind it on the few 10 second run ups I did on the wattmeter but the old tired batts (at the time 25C 8S 3800) did and the batt leads heated up...the motor was cool still...but to be on the safe side I backed down to a 20 x 8...
