I just received 2 more 4s Acepow lipos, the new 50Hz Eagletree logger, Eagletree 10hz GPS receiver for my 4s 100mph quest.
do you use the stock motor mount? i have to get another gear mine is getting pretty beat. the 28 will fit with the 47 with no issue? i was running the 51/26 and that was right on the edge, but im gonna get the 47 and 28. definatley glad to rc monster goes up to 30t now

Default 47t pinion

Where do find the 47T spur for the single speed? All I can locate is the stock 51T.
Thanks

That's an awesome chassis .... now you need the Alpha R2 body to complete it.

I'm using the RC-Monster motormount, as my rides are nitro conversions.

The 47T only comes in steel. You can do plastic 46T, and 44T if you use a center diff.

The 47T can be found at Nitrohouse and it's made for the center spool. Seek the Titan/Blazer spur #40247.

I didn't opt for a center diff and 44T spur, as I'm afraid that I will run out of torque when geared for a roll out of 2.26 and only running 4S. My diffs are allready made for a higher topspeed 44/14, compared to the buggy diffs 43/13. I could do a 40T spur, but will need to go with an 8S setup. I have allready gone the 10s A123 route once before in my GTP and want to do something different. I blew up the diffs within a few speed runs what that kinda power. The diffs lasted longer once I went to the KingHeadz diff cups and hardend ring gears.

Here is the pic of the 47T spur.



Here is the 10s A123 setup running on ipanema's.

AND, since this is the electric forum, we would like to announce that we are now an authorized RC-Monster dealer, and I will have the items on the site shortly!

Default Ofna Ultra GTP2e

Thanks Snellemin for the reply.

How well will the stock diff rings hold up in a 4S w/Tekin 2050-2150kv motor for road racing with 25/51 ratio? Should I invest in hardened steel rings from the get go? Are there any other weak points in the stock car?

What's the approx mph on the straight and run time with a good 5000mah lipo on a large track with a straight of ~200'? Nitro GT's can go 7 minutes on a tank and average 25 second laps and 52-55mph straight speeds?

What starting and ending RPM range should the timing be applied with the above set up and how much? Tekin ESC of course.

Thanks for your replies.

Brand new,it's a special edition sieg sx2, it's a pretty decent mill once gone thru and adjusted etc, if you want a small mill out of the box that's ready go with a sherline ,smaller though and not as much power
For sieg machines sold at grizzly ,harbor freight,travers etc
x0 -micro mill
x1 mini mill
x2 -older model
sx2 - super x2 -brushless -sold at micromark.com
sx2 super special x2, sold at Littlemachineshop.com, bigger table then sx2
I have a Sieg made grizzly 7x12 lathe , my runout is .0005 or less typically,.0002,it's been modded alot ,but no cnc yet
For info go here -

Thanks for your replies.
Stock ring gears in the OFNA and Kyosho cars are similar material, and they seem to hold up pretty well, but you have to check your mesh regularly. On the Kyosho's we can shim our diffs (checking for backlash), not sure if you can on the OFNA's. If you do not check this regurarly, you will destroy ring and pinions in a hurry, even the hardened ones.

Its hard to say on how long the 5000Mah will last during a race, it all depends on how long you are on full throttle and how much you use the brake. I would take a fully charged battery and time how long it takes to cut-off, and then subtract the time before a race you use for warm-up.

I will have to answer your last question later, and I will download my setup from my Tekin, it should give you a good starting point.
