I'm new to TC racing and I just bought a Reedy Mach 2 4.5 turn and a Speed Passion Pro for my TCXX. Will it be fast enough out of the box or do I need to figure out boost and timing issues?

Full boost and full turbo is the way to go with a 4.5 lol

Go to speedpassions website they have setups for various motors.

Thanks, I orginally had a 7.5 Novak in it then bought a older Orion 5.5 and it wasen't much faster that's why I was asking. I 'm still waiting for my Reedy.

I'm pretty sure Ryan's comment was tongue in cheek.

You may want to stock up on extra tires.

I think 10° boost at 30k+ and max possible timing at high rpm on a 3.5t motor is uncatchable...

Why bother turning up the endbell timing on a mod? That kills the overall efficiency, if it doesn't pull long enough on the straight add some turbo. I think Mod motors, especially in one cell racing, should come off the track pretty cold.

Thanks for some of the response and insight guys! More opinions please.

As an intermediate skilled driver (a driver at my club of similar skill level podiumed the amateur 17.5 class at the IIC 2 years ago) that has been driving 17.5 Blinky TC and 13.5 boosted TC the last few seasons, I feel it's time to step up and try my hand at MOD as our rules next season now allow for open motor in the faster classes (both TC and 12th). Our indoor carpet season doesn't start for another few months so I'm trying to figure things out way ahead of time.

Reading thru different threads, I'm confused which approach I should take. My home track is 80x36 feet ozite carpet generally medium-ish grip.

Having never driven anything faster than a 10.5 TC, also trying to get rid of a bad habit of lock to lock steering and not learning how to use brakes properly when I first started RC racing, the question is:

1. Do I start with a low turn motor like a 5.5 in TC (4.0 in 12th) so that it makes it super hard for me therefore get me to learn a more sensitive trigger finger right off the bat

OR

2. 8.5 or 10.5 motor (5.5 or 6.5 for 12th scale) so it's easier for me to start and not get too discouraged as I won't suck as bad.

One thing I'm confused is that I keep hearing you should not run as low turn a motor for the smaller tracks but I'm thinking all tracks have some type of technical sections so really a smaller track just has more technical sections so you just get to practice more throttle control?

Any insight is much appreciated from the fast guys and let's ignore which speedo or motor brand is better to keep things simple.

Ivan

ps. Just also wondering approximately how much mah would be used up in a 6 minute TC run using a 5.5T motor (8 minutes 12th run using a 4.0T motor) in your experience?

Just finally got started in mod this past weekend! No race just practice. So I was wandering how much brake people were using? Speed control settings and controller settings and drag brake? Right now I am using a D3.5, 5.0turn! First time out and at the end of straight car vibrates when brakes are used. I got a slight push but am working in that set up. Esc was at 75% on brake force, 40% drag and forgot what push was set at. I had my controller epa brakes at 60%. I was thinking way less on all of those settings to get a smooth roll to stop unless I am doing something wrong? Any tips on that would be cool! thx Haven't read this thread in a while but am going to start from beginning again since now I am ready!

In modified you want as much drag without putting too much heat on the motor then turn down your initial break the car will be stable under hard breaking..

or if you can reliably push brake, then have zero drag within the speedo. i found that having drag & initial brake within my ORCA would cause me to lock up the tires more and just be overall inconsistent lap to lap. since de-tuning both the brakes and power program modified both outdoors (jackson rc, new jersey) and indoors on carpet (st. cathrines, canada, eh) has been 'easy'. i'm running a team powers 6.5, but might jump to a 5.5 as i'm nearly max timing in the motor and speedo.

^^This. Mike and I are of the same school of thought on this. I am one of those drivers (on asphalt at least) that prefers a freely rolling car with the ability to push brake as needed.

My HW speedo settings with a Fantom Ion v.4 4.5T are 0% drag brake and 50% push brake. It's just enough push brake to bring the car to a smooth stop without locking up the wheels.
