I use Flow with the motor LRP LRP 13.5t stockspec boost.
My 7-digit setup 2344813 6.0 ratio with 40m straight track. When 3 minute run, my ESC losing power, when I check my esc, it shows a blue flickering (like 0 boost indicator). Is it my ESC overheat?

Yes, if the esc overheats and you have thermal protection on, it will go to blinky. I think 6.0 is probably overgeared for 40m, I would drop gear to 7.0, and maybe try different settings (Less aggresive ramp maybe). You may also find the thermal cutoff is premature, and you may be okay turning it off completely (last setting 0). Make sure to watch all your temps if you try this though.

try the 7.5 ratio and mode 7 (lipo cutoff voltage) on disabeld

Thanks geeunit1014 u're much help

Yes you need the file ending in .lrp. when you click it it goes to step 3.

6.0, I usually run a 72-29 or 72-30 on my 13.5 reedy with flow works. Try dropping gearing one tooth at a time and check your engine temps and get a temp gun on your esc too. You can run a fan if needed. You can set all your modes to blinky and increase each mode that has to do with esc slowly also, takes some test time but you may have one setting off a little especially on that 130 foot straight.

72/29? I guess youre running blinky

I usually run a 4.0 whit 13.5 sp

Yep.

Do anyone have this thing working with windows 8 yet? I'm still running the the out the box settings in 17.5 TC with a Reedy Sonic mach 2.

Last I looked it was not.

Notice:
The Win software currently can’t be used with Windows8. The software update works with all other Windows versions without any problems.

running 10.5 boosted ver 5.0 software loaded is this best for this set up or is there another version to use.

Version 3.3 is more of a mod. I run 5.0 on 17.5 and 13.5 and 3.3 on my 9.5 and 7.5.

Which firmware would you guys use with 21.5 (VTA)?
