And the answer is always the same, the new motor thats being released each week, go figure.

Of course, the best motor on the planet will not make up for poor driving skills!

I have been looking at those motors too, they look good.
The D3.5 is fast and competitive u just have to know how to gear it. Its really about the driver, orion and reedy are just as quick and often fill the top spots locally.

Haha boost is a Pain, takes alot of time to get it right and gives guys with alot of time on their hands a big advantage. Blinky is great as you really only have three tuning settings, gear ratio, motor temp and motor timing, doesnt take alot of time to get it right. Going to a new track you can easily tune the motor and leaves you time to get the car setup right.

Yeah. The Turnigy is not ROAR approved. I've raced at a lot of places and nobody ever checks to see if your equipment is ROAR approved. Is it a 17.5 motor? Yup. Good to go. To me, ROAR approved means it costs $90. Nobody cares at my club. I like to race to have a good time. I'm pretty competitive, but am just doing it for fun like most people. I don't know if I'd want to race anywhere where somebody is coming around and inspecting my car to see if it's ROAR approved or not. That's just me.

I think it comes down to how anal the tech crew will be on checking cars. our races spec roar approved goods but most of the races ive been part of just tech the class specifics.. ride height, weight, blinky? turncount ect. hardcase lipo? basically, does your car meet spec and is safe...
im pretty sure no one would be turned away because of no roar stickers.

seems kind of silly. a money making measure and im sure it has a lot to do with people not wanting to get into racing at the end of the day.

but you did get me thinking if my new redline gen 2 rpm is approved or not heh. tekin says it puts out 2700kv which seems like a lot for a 17.5 it was as fast as any of the d3.5 cars, in fact had some extra pull further down the straight. very happy with it.

in single cell though. haven't tried it in two cell, maybe i will this weekend. used the reedy for that as i have both rotors.

If you go by the "kv" ratings Trinity rates the D3.5 at 3700kv http://www.trinityrc.net/shop/index....product_id=397

KV rating is a crock, it is just a measurement of the RPM/volt not of the actual power output. wattage is a better measurement

Two of those guys ran different motors this week (d3.5->revtech, ballistic->d3.5) and where running about same laptime as last week. Those top 2 are a-main locks at the regional level so driving has more than a lttle to do with it. It seems like they are faster but they are just carrying more corner speed so theyget going faster on the straight.

Again... this isn't a fashion show, this is racing. You don't score any points for "being different". You do, however, score points for having a fast car and being a talented driver. Those two things are not mutually inclusive, though, and a good racing program addresses all aspects equally well.

Choosing your equipment based on the fact that "no body else do" is beyond the scope of my comprehension. I'll just leave it at that...

The thing I dont like about the 3.5 is how bad that old school purple looks in my xray and the revtech blue/orange combo isnt great either, does anyone know how a3.5 stator runs with revtech ends?

At my track, I'm sure nobody cares if it's Roar approved either, as long as what you're running doesn't have a clear advantage over the Roar legal stuff. But if I'm killing everyone on the straight, I'm sure people will start to care.

Have you run your Turnigy against guys with D3.5? How does it compare?

I can't seem to find that motor on the ROAR approval list.
