Since we're on topic for FDR 101...

Just for clarification:

To achieve more top speed you run a larger pinion and a smaller spur thus a lower FDR.
To achieve more punch you run a smaller pinion and a larger spur gear thus a higher FDR.

Is that right? Anything to add?

Currently running a 17.5 Duo with an SPX and a 2.18 Internal DR using a 49T Pinion and an 85T Spur (64P). FDR is 3.78 and temps are at 135-140F.

I downloaded a gearchart from Stormer Hobbies and it recommended a 17.5 to be geared at 3.5 to 3.0. Seems kinda high.

 

Just a reminder.We will be racing this Sunday.Because its a holiday weekend,we will start promptly at 10:30am and should be done by 3pm at the latest so you can race and still make it to dinner plans!See you all this Sunday.

I'm running a 100t 64p spur & a 53t Pinion in my TC5R. I have a spx in it with a novak 17.5. I run spektrum. My gear ratio is a  3.77. This combo has worked real well for me so far. Hope this helps.

Any advice for a decent starting point for gearing? Would like to go 64p btw...

Tc5r with LRP TC spec and tekin 13.5

 Tc5R with SPX and duo 17.5  

Both cars running lipo's

What type of FDR's am I looking for? Does not have to be perfect as I'm sure I'll need to mess with it a bit but I'd like to run the cars on Sat and need to get somthing together. Thanks!

We are planning on carpet. We will have to see what the future brings. The layout is fun.

     Thanks Kevin.  The layout looks like fun.  I'll have to give it a try on Sunday.  Are you going to carpet or paint the infield?  I would think painting wounld be easier/cheaper. 

Here is one picture. We where waiting to post till it was perfect, but the green infield is on hold.

     Is there a pic of the current outdoor asphalt layout?  I've found a few different ones, nut sure if any are current.

You were so excited about going, disappointing news...well, I'm glad we still get to race with you - for a while, until you ship out

so bad news and good news.  I got disqualed during my military physical because I had arthroscopic knee surgery in June and I have to go back for a medical review in a few weeks.  A ship date is still to be determined.  :(  SO for the mean time I am still going to be able to race.  I am bitterly disappointed but at the same time this in an opportunity for me to get better prepared.  See you guys on Saturday. 

     TC this Sunday sounds good to me. Will there be a Slash class?

I got my new TOP car coming and should be ready for Sunday. Im in for Mod. Lets get a mod class going this sunday
