Sounds good. Ask Bob to make an exception and make a 1.5T for this occasion.

SpEEdyBL 09.11.2008 03:30 PM

You are going to need more than 5000 mah 25c batteries if a 1.5 turn hv motor is going to be any use at all. I would recommend at least two of those in parallel. My hv 4.5 already taxed my maxamps 5000 mah batteries and a I imagine a 1.5 turn would have the capability of drawing three or four times as much current even with only 2s, compared to a 4.5 turn on 4s.

When is your speed run and where? If you have any other info on the esc it might be worth posting it----if this combo just won't work, it would be better to discover that now.

If Bob or Steve have questions about the controller, I will have them contact you privately at this email addy.

I have the order ready to go.

Maxamps don't count in my (and many other's) book and all and I mean all Maxamps don't even come close to what they're rated for. My packs have seen upwards of 180A+, I will also have 30C and 35C packs on the way and it should be fine. Most of the higher quality cells that I use are good for bursts of over 200A and for the few seconds that will only be needed for the speed runs everything will be fine.

As soon as the motor(s) come in, I'll start the runs. I've been testing with a 4.5R and with 35/69 gearing in my TC3 it went only 65mph in a short test. The 200A ESC is on the way and it should be fine with the 2 winds mentioned. If that ESC isn't enough I'll just find a way to strap the big dog Schulze 40.160 and let it all out. I can place the order right now for a 1.5T and a 2.5T, but they must have kevlar wrapped rotor (Or any other high strength fiber such as Spectra) and the strongest magnets on them as well. Have someone who handles the orders contact me via e-mail and I'll either call or e-mail the appropriate info for them to get this done as soon as possible. I'm really serious about this and if there's anything Bob or anyone else would suggest for the motor before they get built, let us know.

Regards.

lutach 09.11.2008 04:56 PM

Just replied to Bob Novak and now lets see if the 1.5T and 2.5T can be done so I can set the standard for 2S lipos speed. This will be very fun to do.

Hi Lutach....I have forwarded your comment to Bob and Steve.

I think you missed a couple of my posts above:

We will only wind a 2.5T HV Pro motor

We will not wrap it with Kevlar/epoxy, but the magnetic material in the HV rotor is our highest temp magnet and it is the only rotor we (have) use in the HV motors.

When do you plan to run this and where?

Arct1k 09.11.2008 05:09 PM

Just use 2 of the 30c 5000 mah in parallel - you can take 300amps continuous!

I just answered Bob. I know you mentioned the only one made will be be the 2.5T, but see if the 1.5T can get done as well. So your rotor assembly without the Kevlar wrap can handle high RPMs? I'm only asking about the Kevlar wrapping, because my 4.5R has a Kevlar wrapped rotor. As soon as I have the motor(s) are here I will start running and the location I go to is brand new paved road and it's wide and very long. Here is one of the videos I made there: http://www.youtube.com/watch?v=ZaquBD-lr6E.

NovakTwo 09.11.2008 05:17 PM

Bob said that will do the kevlar wrap.

snellemin 09.11.2008 05:21 PM

hmmm getting more interesting.

TexasSP 09.11.2008 05:23 PM

This is getting interesting for sure.

Thank you. What about the 1.5T. I can't get over having one as well and I won't be sleeping too good if it doesn't get done. If you don't have the magnet wire in stock that's needed, I'll be more then happy to get it.

Darn it. I should have kept this as private as I could :lol:. Oh well, you guys don't have a 200A ESC that has dual mode for sensored and sensorless operation :tongue:.

Well Okey, dokey then....

Lutach, you can just email Bob directly. My "conduits" are overloaded....:wink:

Bob sent me an e-mail and I replied to him right away, but he hasn't replied back.

lutach 09.12.2008 08:25 PM

Things will get interesting in a couple of weeks. You'll all see :diablo:.

phatmonk 09.12.2008 09:32 PM

What about putting a Novak 7.5 HV Pro ESC motor system the 5mm version on 3s lipo in a Slayer conversion?:diablo::whip::diablo::whip:

Not fast enough for me :lol:. Hopefully the 1.5T and 2.5T will be here in one and a half weeks from Monday. Should be lots of fun.

lutach 09.18.2008 05:33 PM

I'm very excited about this answer from Bob:

"The motors are done except for the rotors which were wound with Kevlar thread this morning. The glue has to dry for 24 hours so we will be testing them first thing tomorrow. I will let you know what the KV of each motor after we test them."

I can't wait to have the motors here.

JThiessen 09.18.2008 06:38 PM

After you toast them, can I have the cans????? :intello:

I'll just keep them as suviner as what will probably be the first 2 of it's kind. One question though? Does the normal 2.5R gets toasted? You know they are at 12,000-13,000Kv :intello:.

SpEEdyBL 09.19.2008 01:58 AM

Neither should be any worse than a HV 4.5 on 5s.

lutach 09.19.2008 07:59 PM

Alright :yipi::yipi::yipi:. The motors are ready and they'll be shipped on Monday. SpEEdyBL was right on the money with the Kv values. Here is what Bob has just sent me:

"Here are the KV tests I did on the two motors.



Input voltage measured at Speed control power input





Motor Vin Aload KV

2.5 5.0 3 7900 Free running (no load)

2.5 4.0 30 7125 Loaded

2.5 5.0 43 6960 “

2.5 6.0 57 6700 “

2.5 7.0 73 6515 “



1.5 5.0 9 12,630 Free running (no load)

1.5 4.0 91 9750 Loaded



As you can see the 1.5 is pulling a lot of current at 4 volts so I did not want to run it at any high load. My suggestion would be to run the 2.5 for most of your runs and then use the 1.5 for the last few runs in case it blows up.

We will ship the motors Monday."

I have no idea what size you wear, so I would not bother...

Have fun with the speed runs!

Those motors are going to be freakish!:surprised:

I can't wait to see how they perform (I'm really curious as to how hot they'll run).

They won't be running a lot though. I'm only going to use them for speed runs. They will be shipped out today and I've just heard the 1.5T is a first for Novak so I have a one of a kind :lol:. The 2.5T has been done before :grrrrrr:.

Five-oh-joe 09.23.2008 10:54 AM

If all goes well, will you also be bringing in that 200 amp sensored/sensorless controller as well as your two other models?

I can't wait to see video of these motors. Should be really fun.

Yes, that's my plan.

Five-oh-joe 09.23.2008 10:42 PM

Neato, sounds good. I've always wanted a sensored/sensorless controller that would run cool, didn't cost an arm and a leg, and could handle at least 3s.:lol::yipi:

The factory said they can be programmed to handle more lipos if the BEC is disabled. The BEC on the 100A and 200A can handle 3S lipos.
