Johnn27 what motor are you using for that gearing range?
Iím using a hobbywing 21.5 at about 39-40 degree timing.1s battery. Iím currently geared at 68-49 and I have absolutely nothing for the top guys. Theyíre turning 11.6 - 12.0 lap times and my hero lap is 12.2. I canít seem to string low laps together. Itís not much fun when theyíre pulling 11.6ís and I have to pull over for them. Feeling a little frustrated about this

my Reedy Power Team Associated 12R5.2 in GT12 was really good for the 1st time in a race. This class is fun and just fast enough. Simple and a drivers class. Ill be back for more and more. Fun racing with the Apex crew, and special thanks to JB2 and Terryl for all the help.

Great picture of charging your battery in the car. I did that and poof there went the whole car in flames with no warning. Even saw someone at the Snowbirds that made the A main do the same thing. Don't say that won't happen to you- it can. Have fun.

This may be all the motivation I need to rebuild my AE 12R5.1 backup up as a GT12 car. Thankfully the car already has the lipo chassis.

yeah it was really fun and fast.... I know nothing about 12th scale, but I have a great support system at Apex...so getting up to speed was fairly easy... Its pretty much a base setup, like maybe for 17.5 12th Scale and tweaked from there

He could be just monitoring the voltage to keep it close to 4.20. I do that in every stock class I race. Also, it is very rare for a lipo to blow just charging in the open. Heat is the enemy and friend to Lipos. Just enough, low IR's and great punch, too much and poof. Had that happen to a pit neighbor at the Full Throttle race because he was charging in a heated Lipo sack and it overheated.

That happened to a guy at our club too. Charging a WGTR 1S pack in his car and poof. Whole chassis destroyed. Charge in a lipo safe bag.

I'm really starting to become a fan of bullfrog, he's got a lot of natural talent for making people mad.

To Bad! 3-4 amps and had one to destroy the entire car. The guy at the hobby shop lost his entire house and he was charging at low amps. How about discharging a 5 amps- When it happens to you good luck. Two of the others did blow at a high amp charge. So you are experts on when and how the blow- Just don't want that to happen to anyone! I use the the battery box only to charge and discharge the batterys- it's always better to be safe than sorry but then that's just me.
