We will run a heat of WGT if we get 5 to show.

For people running the Ballistic 25.5, do you max out the timing or what do you run?

It depends.

I've heard that some do run max timing but only after closely monitoring their motor temp to be sure that their FDR is correct and their motor doesn't fry.

On the old layout, I ran my SS car (TC6 @ 1455 grams) with the motor at the "N" mark, a 30mm fan and FDR of 3.45:1. In this configuration, my car seems to be even on zip out of corners and even on top speed with the others, and my motor temperature is 140-ish. I haven't run my SS car on the new layout yet but I'll bet this FDR will still be in the ballpark.

Hopefully someone who's been racing SS on the new layout can comment.

My FDR is 3.52 and I run a 30mm fan. I didn't mess with the timing at all yet, but it seemed my car was about the same speed on the straight as others, but not nearly zippy enough in and out of corners.

We've found that with the ballistic 25.5's, 40 degrees is about the limit. Ritchie brought that to our attention and its spot on. The motor seems to drop off after 40. Motor temps are an issue though, so check that frequently. An fdr in the 3.4's like Bill said is a great place to start with timing. As you become smoother, you can bump that up if needed.

I've been running my ballistic at 3.6 FDR with 44* timing and a burly 30mm fan. Seems good on top speed, scoots well out of the corners, and never seems to get hot.

I probably need to play with it more, but 3.4 @ 40* felt awfully flat, and my overall run pace and ability to defend against Jesse seems to be better with 3.6, because I can recover from small mistakes a bit faster.

It also depends on how well your car is handling. If you're having setup or driver issues resulting in lower corner speeds, a higher number FDR will probably work better.

The car makes a difference as well, as does the speedo, etc.

Speaking of ESC's ...

I noticed USVTA updated their rules to allow the Hobbywing Justock Club Spec ESC (it's also ROAR-approved). Then I noticed Hobbywing is having a sale. Fifty one bucks? What?!!!!! For a brand new ESC? Whaaaaaaaat?!!! Check 'em out @ http://www.falconsekido.com/

Thought I would let you know in case anybody is looking for an ESC.

Before it gets out of hand I will post that ROAR has made the decision that all Trinity based D3.5 17.5 motors are not made to ROAR specifications. This will be a serious conversation for the Competition Committee. We will post more tomorrow as most of the CC are dreaming about Saturday's racing and not reading there emails!

Below is ROAR's official release on this matter,

After a great deal of consideration the ROAR Executive Committee has determined that the Trinity D3.5 motor and others based on the D3.5, do not comply with the organizationís required specifications for motors in the 17.5 stock class. The determination is based on the fact that motors being sold are built with wire thatís larger than maximum specification permitted. All of the random samples of the D3.5 based motors during the announced compliance checks tested with wire thatís larger than the maximum dimension. Rule 8.8.4.3.1 states clearly that ďThe three slotted stator must be wound with 17.5 turns of 2 strands of a maximum diameter of 20AWG or 0.813 mm per slot. A diameter of .813mm is the nominal measurement of 20AWG wire, and that it is the stated maximum wire diameter permitted. Itís on this basis that the Executive Committee made its determination.

Default D3.5 Banned by ROAR

Since someone is sure to notice and post it, as of tonight:

Wonder what mine will fetch on EBay?

Glad I didn't pull the trigger! I almost bought an EAM 3.5 today, settled with a Reedy instead
