Adam, I've always had good luck with a HT rotor 12.5mm and geared about 3.8 FDR. That was outdoor though. Carpet maybe 4.0 FDR. Timing one notch back from max to max. Make sure to always use a GOOD fan blowing lots of air on the motor. It drops the motor temp almost 20deg. Good luck buddy!

Mmmmm I believe the killshots have a different circuit-board and allow more timing but other than that I'm not too sure.. And I think that the RevTech Killshot motors are only designed for spec racing (i.e. 10.5 13.5 17.5 21.5)

I ended up ordering a 21.5 Ion and so far I'm loving it. I may get an Apex for stock racing, as D3.5-based 17.5 systems are frowned upon and/or disallowed around here.

I'm relatively new to mod as well. I have been told by the fast mod guys at my track that running a 4.5/5.5 should start around 8.5-9.0. I would think if its a tight track I would stay on the high end of that fdr. Our track is 96x40 and my 4.5 was geared at 8.8 and was coming off at 120*.

Yeah, a few places do which I think is kind of retarded.. If they don't like the motor because it's too fast: suck it up, lose some of that 'Brand Pride,' and buy the motor yourself Look at drag racing, the other companies weren't banning the use of the Hemi, they were creating their own variants of it!

Our onroad club kept the ban on the D3.5 even after the court case was settled. They don't want to allow it just to disallow it again next year when ROAR bans it for good. I can kinda understand their reasoning, but at the same time this whole thing is a huge mess. The topic has been beaten to death anyway, so I'm just sticking with the club rules to save myself an ulcer

I still run a D3.5 (non-Fantom) on the local offroad track and it's great. But, I think I'll be going with Fantom motors from now on, great service and great motors, who could want more?

Unfortunately our VTA class is still sticking to VTA rules, so Novak for all. I'd like to meet the business genius at Novak who got that deal signed, talk about a forced monopoly.

I know years ago schumacher used to import fantom into the uk,is anyone doing it now???

What is an ideal coil resistance for a 17.5 stator? Both Ion4 and Apex2. I know they need to be close to each other, but what is considered "good"?

Best numbers I've seen have been in the low 19's. Most of my 17.5 motors have been in the low 20s though.

I'm sure they show a difference on the dyno, but I doubt you would notice anything on the track. A higher resistance stator is going to like a little more timing, however.

Andrew was telling me to gear my 5.5 TP at ~8.0 to lessen the torque. I gotta say it helped a lot.

I just picked up an orca 4.5 so I'll probably gear around 8.5.

I have collected a lot of data with my MMS and shared info with 2 of my buddies who have their own MMSs. What we have typically seen is that really good D3.5/Ion4s are in the mid-low 21s/high 20s... Typical off the shelf motors can go anywhere from mid 21s to mid 22s.

The best #s I have ever heard of from our 3 MMSs have been high 19s/low 20s(19.9, 20.0, etc).

One of our local racers has an Ion4 that has 19.1/19.2 on the sticker... I would like to look at it on my own MMS to see how it measures out, as those #s are much lower than anything I have ever seen/heard of for a 17.5.

Anyway... a good rule of thumb is to take any resistance #s with a grain of salt. Machines can vary substantially from each other depending on how they are calibrated or the quality of the connections/alligator clips/solder tabs/lower stator ring... and temperature/climate plays a big role in how the measurements come out.

i'm wondering if we'll be seeing any of the 'brick' packs for Lipo's some time soon? Like the single-case saddle-pack that Reedy introduced a few months back. I might just stick with shorties but I'm just wondering

Hi guys,

Have decided to take the leap and run Phantom motors from now on.

(Old saying if u cant beat em, join em)

I have a big T/C, 13.5 class race meet coming up next month.

Out door asphalt, Med grip, Med-large flowing track. Back strait is about 110Ft, (33Mtr)
It does have 2 tight 180 Deg switch-backs in the infield though.

1/ Should I go for the Apex V2 or the Ion V4.?

2/ Is the Ion a D3.5 based motor?

3/ What Stator/Rotor combination would be best

4/ What FDR should I be looking at?

Thanks in advance
