R/C Tech Forums - The Speed Passion Thread

I just picked up a LPF 2.0 carbon edition, and have one question. In the set up instructions it shows a LED that is somewhere on the solder posts side that you can look at while programming your radio set-up. For the life of me I dont see the LED, even a place for it. I even pealed the "A,B,C" decal back a little to see if it was covered up. However I do hear the set-up tones and got it done. Just wonder what I'm missing, or not seeing.

I had the very same problem, I had to sit in a dark room and then I could just about see the LEDS . :weird:

yeah it's much easier to use the tones,

holding down the setup button it will beep consistantly...

Push once for neutral, it will beep once

hold full throttle and push again it'll beep twice

hold full brake and push again it will beep 3 times

turn off then on and your good to go

hi,
i just want to ask 1 question. On the speed passion LPF v1.1 box, it said that the motor limit is 5.5t on 7.2v. My question is, if I'm using 7.4v lipo battery on a 5.5t bl motor, would it damage my esc??

LPF V2

Hey guys, new GT2 is awesome, But now am thinking of LPF for youngest son who races 10.5. Does the LPF have any speciaist stock profiles for the speck classes like the SPX? Also what is timing on the fly I have seen mentioned on the LPF,, thanks in advance

Hi Guys

Thinking of getting a SP GT2 as a back up speedo.

What i was wondering though, would i notice any power difference between the LPF and PRO version running 6.5/lipo.?

Thanks in advance

Heya,

Could anyone explain what 'AMTS' Timing settings on the program card do?

If you could explain when and why you would change the timing that would be great

Thanks

Check post #16 on page 2 of this thread...excellent info on gearing/timing advance relationship!

After struggling with cogging issues for the past two weeks with my speed passion LPF v2 + 10.5, I decided after reading on here from someone else to move a shim to the other side of the rotor so it sat closer to the sensor.

This worked and solved all my problems, my question to speed passion guys is why should I have to do that? Surely the motor should be ready to run out the packet...

just like with brushed motors, double checking everything first is a good idea. glad the re-shimming worked

Hiya

First post here so be gentle

I have ran brushed for a long time now and ive decided on going brushless with my cyclone TC , i decided to go for 13.5t speed passion combo , but im not quite sure how to gear it at the moment

The tracks i run are a small indoor carpet track and a slightly larger outdoor asphalt track , currently i only have a 84t spur and 23t pinion with all the standard pulleys , i want to get some new gears but dont want to end up buying all the wrong ones , so im after a rough guide as to what range of spur/pinions i should get...

Also i do have the brushless motor mounts if that makes any difference

oh and also both carpet and outdoor tracks i run rubber and 7.4v 5000 lipo

Thanks for any help/advice its really appriecated because i am lost

Mark

Well i have got the speed passion 13.5 combo , i decided to get a 78t spur/36t Pinion and are 48DP , it works out at 4.68 FDR....

I ran my car for between 5-10mins and i checked the temp , i have no thermometer so i just touched it with my thumb , i cud only hold it on there 2-3 secs , it seems to run too hot or is it just me ?? , i even turned the motor timing down to the lowest and is still very hot , also i have got the over heat protection setting 'on' on my speed control but this didnt kick in

am i worrying about nothing ??

What is your track like? is it tight and technical? open track? How much drag brake are you using? how hard are you driving the car? There are alot of things that can make the motor hot besides gearing and timing.
