thanks.
try direct soldering your wires. ive gone from deans, to bullets, to direct solder, back to bullets, direct, etc ..... direct just works best for me and have been doing so the past 3 years. i recently noticed a lot of the local guys at capitol speedway using bullet connectors even on their motors. dunno how all that started but i guess its mainly because people are a bit lazy to solder on their wires. admittedly its a bit more work compared to using connectors but it works much better and should provide less resistance and possibly less heat build up. at the very least, solder on the wires to your motors. 8s and 7s are very hot winds so likely the cause for your wires "de-soldering". just somthing to consider.

Don't be too sure about it. . . . Most, if not all, of the guys you'll be running against will be using DC stockers as well.

Peace bro!!! Looking forward to your return.

I think that super high silver solders are supposed to help against this, one of those might be worth a shot. I believe the MuchMore has one of or the highest silver content. I've never unsoldered a motor wire in all of my racing , must be the solder...... skills .

Hi Bluey-74

I have run a DC19T ultralight at Tempelstowe about a 35 metre straight I know the Little Hampton track up hill onto the back straight. Raced nitro there.

I use 6.4 to 1 with rubber tyres at TFTR with this motor,I would start at about 6 to 1 that uphill to the back will be hard on everything!

I'd start with a FDR of around 5.0 and work from there, you will probalby need to gear up a bit.

I have run the Outlaw as low as 4.25 without any problems on a fast track. (large, no slow speed corners).
Problem was the heat lasted 6 minutes, but my battery didn't

Kind of hard to tell how big the track is from the photos, I'd say start with a 5.5 FRD and go from there (I'd rather have you start out under geared than over geared)...


Curtis,
