    Who races with 1P in open classes (non spec classes) 40" mono setup questions

    Thats it.

    I was curious what boats can pull off 1P in oval race trim for 7 laps 1/6 mile oval?

    Can 1P work in a 40: mono with a 1200KV 5694 HOR motor? It is rated to 10000 watts max or was it 12,000?? Anyway, I melted 6S2P 25C nano-tech on the first try pretty much. Cleaned the boat out and I'm rebuilding, just don;t know what cells to get (Turnigy) for this to do 7 laps open mono.

    Motor & ESC are bullet proof, batts & prop I'm lost???

    Help...

    2P Set-ups

    All of my high current draw boats are 2p.

    N2 Mono
    N2 offshore
    N2 Sport
    N2 Hydro

    P Mono
    P Offshore
    P Sport

    Q Mono
    Q Offshore
    Q Sport
    Q Hydro

    T Mono
    T Offshore
    T Hydro

    Wow 14....that was more than I thought, just had never written it all out like this.
    2p makes most systems run cooler too.
    Hope this helped,

      It is no surprise to me that the 25C HK cells burned up in an open powered boat - I've seen quite a few do that, but never a high-quality cell in any sane setup. I run 1P in both Q and T boats, using ThunderPower 65C/6600 mAh and Hyperion 45C/6500 mAh cells. I have plenty of capacity for 7 laps of the 1/6th oval including mill, using between 4000 mAh (Q Sport Hydro) and 4500 mAh (T Cat). So 5000 mAh is not enough to be safe, but 6500 mAh is with some to spare with my setups - which are pretty fast.

      Q - Neu 1527/1Y and Castle ICE240
      T - Lehner 3060/10 and Schulze 40-160

        Yes, I was pretty silly to try those cells. Do you think 7S is better than 8S for 1200Kv??

        Thanks for the responses so far.

        I'll be running 2P in the mono. HK makes some HighC 8000's but, I'm not taking a chance on 1P with their cells.

          I think that 7S would be far better for most use. That will still give 27,000+ loaded rpm.

            Yeah, thats what I'm looking at. Now to save up for some decent cells and what prop to start with, X450 2B?

            Thanks.

              Jay are your TP packs 2p 3300. TP doesn't make any single cells above 5000 that I'm aware of.

                TP sells 6600 packs in 2S through 6S, each actually has 3300 mAh cells connected in parallel. They are just slightly larger than 5000 mAh non-paralleled packs. The problem is shipping cells over ~5500 mAh by air, something all pack assemblers have to deal with.

                  Mark, Jay is correct... They make 6600mAh packs... I ran a pair of them for the P-Ltd Offshore class at the Nats...

                    I run a Big ass HERZOG Hurricaine 46" with a Big leopard don't know the model but its (910kv) on 8S Hyperion 6500's and TP 6600's and 7700's does 63-64 mph and can go at least 8 laps on a full 1/6 mile course. uses about 4200mah after 8 laps (full mill, race, and cool down lap)

                      Much respect Mike.

                      I've got my 40" mono and a big ass TP power 1200Kv motor. I used 6S2P 25c crap and they burnt up. Motor esc & boat are fine.

                      What do you suggest? Toss this motor and go with something like yours? Or what cells & prop? Some say 7S some say 8S???

                      Is that 1P or 2P?? I forget?? I saw the boat run and it's pretty crazy fast.

                        Darin, I know what sizes TP has. He asked about running 1p for which the TP 6600s are 2p 3300s wired in parallel. Does TP make a single 6600 mah cell?

                          No they don't make anything bigger than 5000's Mark, the 6600's and 7700's are internally paralleled but it's still 1P in my mind because it's only one pack! I'm not externally paralleling the packs....semantics semantics. Ray I don't personally know anything about the motor you're using but 1200kv on 6S 10,000 mah 45C or higher with a 452-455 prop shouldn't even be an issue. My Orange cat that you saw in canada (was pretty quick right?) has a NEU 1527/1Y (1250kv) with 6S2P TP 65C 5000's and will run over 60mph for 4 minutes, it's my offshore setup, (probably 14-15 oval laps) with a 452/2 detounged with 5.1" of cup. Your motor with good batteries and a 455 should be able to get similar results. You haven't told us what Hull, prop, the weight and how the boat was running? these things are important!!!!!!! even those 25C nanotecs should not have melted down if you were propped correctly and the boat doesn't weigh 22Lbs!!! If you're looking for really good cells at a really good price then check with Mark F and Dinogy cells. get some 6S 65c 6000's I ran these cells (but 8S) in that big herzog in Mi and they ran great 8 laps on a full surveyed 1/6 mile course and I still had 20-25% left in the batts, and they're probably 35-40% less $$$ than TP and you can't even get 6500 hyperions anymore. Honestly Ray for your boat I would put a NEU 1527/1Y on 6S 6000's and call it a day!!!!! But I don't know what hull you're running!!! let us know the hull, weight of boat, and the prop you, were running.

                            Thanks MIke. I'll give your post a good read over and when I'm more awake I'll give you more specs.

                            For now hull with hardware, no 5692-1200kv in there, no batts and no SF240. First I tried a 54mm 2 blade Graupner plastic prop and it was a dog brought it in after a lap or two. The hull is a Chinese Promise hobby Carbon Kevlar hull. He used to post them on Ebay but, recently he only makes them to order and he is on holidays. It is basically a DF39" mono like Steve sells.

                            Later that night I tried a 5714E/ 3B propshop. It went really well and again only did 2 laps and the cells were bulgy and not too happy. Can't remember Mah pull?? The next race day (2 day event) I tried a 2 blade x455 and It was kinda slow compared to other boats, 1/2 speed in fact and after 3 laps it slowed and smoke ensued to blast out of the taped area.

                            I know, propped all wrong...

                            I really would rather run it on 6S but, much better cells.

                            If you say 6S but, better cells I'll give it a go. I can afford some 5000Mah 40C Zippies 2 packs total 10KMah. Will that cover my 250 amp draw from this motor?

                            Its a Head of the river version of a TP Power motor but, the coils & rotor are 1/2" longer compared to regular TP power motors. Rated at a max of 12,000 watts:

                              I run 2p in a lot of my boats. They fit in the boat better. My Q sport runs a pair of 3300's or a pair of 3700's. So the same thing Jay is running only not in a single package. The fit on each side of the stuffing tube with the motor mounted forward.

                              I try not to get hung up on 1p or 2p and just try to get the mah I want and/or the best fit for the boat. My son ran our old Titan on a pair of 4s3300 TP packs. It doesn't need 6600 mah by any stretch but it made the CG and balance easier with that old gear drive in there.
