same problem with PS FK.

we can CA the wire leading to the comm, or run at reduce track votage

[Tim Neja]

It they keep dying at that rate--nothing will help!! %10 attrition is way too high for my liking.  We're only running 13.2 volts now!  

[bbr]

maybe the RH is still a viable power source for the GrF racing, a couple tenths slower, not so much of a handful as the torquey Phx...

 

we seem to want to go faster... but as they say speed cost $$$

 

either way... I have not thrown a wire on a PS FK nor  a Phx, maybe I am not going fast enough, lol

[MSwiss]

There is hot 13.2V and low 13.2V.

The size of the wiring, how well filtered the power supplies are, will all be a factor, on how hard the power will be on the motor.

With Jim Swofford doing the wiring, I'm sure it's plenty big.

With the Phoenix being a hot wind, it's not a natural choke, like a Hawk Retro.

[bbr]

it would be interesting to find out when the wires are being thrown: at high rpms or initial start up.

 

I don't hit the power very hard, so the initial start up torque is not that harsh (electrical motors has highest torque at zero rpm, thats why Teslas can melt their tires) maybe thats why I haven't thrown a wire???

[Eric Claburn]

First off retro hawk is alot slower almost a second slower if we could gear the phoenix. Retro hawks are all over the board maybe 1 out of a hundred will be fast and consistant. The phoenix is new and not perfect but in my opinion a much needed upgrade. so far there all pretty fast with only a few hick ups. These motors even the playing field without breaking the bank.
Reto hawk 442 laps $13
Fk 456 laps $14 plus alignment
1st race with phoenix 481 laps $17
These are bpr records

[bbr]

well ... the playing field is never even.
the fast guys will always be fast, and the slow guys maybe a little closer but will not be faster than the fast guys.
 
the fast guys know what it takes to win... while the slow guys don't so they try all sorts of things, most of the things they try are useless, wasting their energy, lol
 
watch what the fast guys do and learn from that!
 
 
Phx tuning:
more AC
softer tires
mush button and choke

Also the Phx brushes are soft, may last only three races.

[Eric Claburn]

The motors are more even yes there is a difference in driving and tuning

[Jason Holmes]

Remember if you go to a smaller Pinion to try and slow them down you will be turning more R's which will cause a better chance to throw a wire maybe a 14/37/36 your next race the trick is to start off slower and reach the peak as you hit the bank  Me I would take my chance's with 15/38 But I do think with a 13 you are spinning them to hard at the start my 2 cents  

P.S. and Big tires 775 plus to start     Play on

Well said i believe a larger pinion would definetly tame the starts

[Tim Neja]

Well the first time I tried a motor I had a 15 on the Phx.  The track was junk and the car wouldn't handle with old tires--but it went down the straight and through the bank like a MISSLE!!! I'm not sure the "B" class is ready for that!! We need to stay the course for a few races to see if we can all get them to handle well and keep gears in them!! It seems SEVERAL people had gear issues with this torquey little bastard!!

[bbr]

Burnouts and wheelies... thought we were drag racing, lol

 

in the race I ran three feet of choke until the tires got hot and the magnets lost some of its strength... about a minute into the heat.

 

also a mush button would be helpful on starts and restarts, my SK controller had a choke but no mush button, have to bring out the difalco with the choke and mush button... almost sold that controller, glad I kept it!

 

been using the axles with flats and running the mesh a bit tighter.

 

will be trying WH tires at next race!

2 words; "weighted guides".

You guys might need my limited edition tungsten insert ones.

   Perfect class for this little advantage.........

I tried adding weight to the nose with NO affect.  It's simply a TORQUE thing!!   I turned my sensitivity all the way up so it would start up very slowly--then it was no problem. The choke's not a bad idea either!! 

[wjtaylor]

I really don't think it was the cars. Remember everybody was suffering with popping and chattering and with the general misbehavior of their cars in practice.

 

The first race of the day started out pretty awful with the same issues. About half way thru that race the cars started to settle down and by heats 7 and 8, the track was really racy. In the second race the cars and track were perfect and in the final race of the day, a track record for the class was set.

 

Someone accused a scale racer of ruining the track by practicing with his retro cars. I know who that was and i am not buying it. This racer would not have laid down enough rubber on all 8 lanes to have the negative effects we experienced. In fact i doubt very much that this racer ran on more than 3 lanes.

 

Me, I think that the problems were caused by the way the track was prepped. Now whether it was not cleaned correctly or not sprayed properly or with the wrong product, we will never know. But cars that were perfect in the last race, could not make decent laps for practice this race. What changed?

[Eric Claburn]

Wheather has alot to do with the track and glue was different. And only one of racers did his homework ( scale racer) that you where talking about bill. None of us where prepped for the track that day next race will be different we all have to learn a new setup and i personally like the new motor so far

[guitarist gone bad]

Just out of curiosity what is the length on the Red Fox Box Stock/Gp12 chassis? Has anybody tried this chassis on the BPR King and if so what were the results?

Thanks

JB has a couple in different lengths

Yes, it seems crazy (not literally) that one would think you could run the same set-up with such a faster motor.

 

Especially one with full Neo's, and super-heavy cog.

 

Also keep in mind, that with those mags, the thin space between the lam tips, and the bigger wire, I'm pretty sure the motor is somewhere around 2G heavier.

 

Maybe someone with both motors, readily available, can confirm that.

 

I don't want to pull any out of the package.

 

That would certainly change the balance of the the car, front to rear.

[Jason Holmes]

Yep 2.1 Gm's more things are 4.6 more than my Box Motors 

 

jason

 

Keith I think the RF's are to short for BP at 4.05 unless you know how to drive Black and Purple I still think a 4.3 car is the easy/fast way to get around 

[wjtaylor]

Give us a list of weights up to G12

[Jason Holmes]

Bill

 

RH  23.4

PSFK 22.7

PHX 24.8

G12 20.2 W/shunts and DBB

[Pablo]

Has anybody else experienced when a Phoenix is put in an anglewinder flexi chassis, the pull from the super strong mags actually binds the axle? Or is it just me? Signed, perplexed in Mississippi

[86ed once again]

That little motor is 2 grams heavier than an FK and 4 grams heavier than a boxstock? Sheesh!! May need to rethink body, kit and/or tires.
