Default B44 motor/esc choice for short track?

hey guys....

I'm finally going to build my back yard track this spring. I'm having about 90-100 yards of clean red clay delivered as soon as the weather clears up. The track will be about 48' X 80' , with 4 - 10' wide lanes. It shoulod be able to get extremely hard , but i'll keep it a little sticky with dish soap or something to that affect.

Question.....i will have a couple jumps coming out of turns that are going to need some serious "GRUNT" to clear them clean , and some rythem sections that will need some extra power as well.

What motor/esc is a popular set up right now on these B44's? It's been a while since i've even looked into this , and the damn B44 thread is huge!

I'm gathering it may be between something like a 3.5 to 5.5 motor. And i'll be running saddle pack lipos.

If I could get some advice it would really help me out.

And like i said , it's not a huge track , but long enough to get full throttle for a few seconds on some of the longer areas , but i need the power out of turns and for some pretty cool rythem sections.

Anything out now would be good....or do you know of a setup that's hasn't been released yet , that may be good also?

Thanks guys.

well the 100x55 layout i go to, littered w/obstacles, turns and jumps (hence the name bumps and jumps). many of the guys are runnin 4600 castles or in the sensored world 6.5 or 7.5s. but nowhere close to what ur thinkin. and this is on high traction hard clay (indoor). even castle guys who thought 5700 would be logical for 4wd have ditched for 46s

Hello, i think the ESC can be LRP Sphere TC, team orion race spec, or Speed passion. And motor its not a 3.5 i think 5.5 or 6.5.

JEFFRO503, I run a 6.5 sintered in my b44 and it is WAY more then enough!! Last year I ran a 5.5 bonded and it WAS CRAZY! I don't think I got the speedo out of the lowest settings but I had to use what I had so... If I were you I would put in a 6.5 sintered in it and run it! As for speed controls I am running a lrp sphere tc spec.

So you guys are saying something along the lines of a 6.5-7.5 motor? I wasn't sure exactly what to get , but i just needed some ideas on how much power some of these newer motors put out.

I had ( still have) a Losi XXX-4 with an older brushless setup that is a novak 5800 SS ( with only about 2 hrs run time on it....still new), and that damn thing would heat up and thermal on me about every 4-5 minutes. Granted , it's a motor design that is about 5 years old , and i think some of the newer designs run a lot cooler than these older ones.

Also....my track may be getting slightly dusty at times to , so the traction may be a little slick at times. But for the most part , it'll probably be hard packed blue groove.

ya, i'm thinking 8.5-10.5 also. 3.5-5.5 is way too much motor for a small track.

Should i be looking at the LRP , Novak , CC , tekin? I don't mind paying extra for something that is durable as hell.

By the way.....do these newer ones stay quite a bit cooler than the older motor/esc's? I thought i have seen some guys actually run a fan on their esc....do most of them have the fans now?

Damn , those tekin setups are spendy! They weren't around that i knew of a few years ago. Are the LRP brushless motors still having bearing problems?

crap....sooooo many choices now days.

I think i'll be looking at a 6.5 setup , so when i hit some bigger outdoor tracks , i can still have some juice.

Default ESC

My advice would to get a standard lrp brushless competition esc without fan but you get a heatsink included. Do some temperature tests and if it get a bit to warm then but a fan i got a muchmore fan which is identical to the one on the LRP TC Spec esc and its awesome. You save alot of money by doing this and you have the highest spec esc available for the price of the cheaper version.

LRP TC Spec ESC with a 6.5 or 7.5 X-12 motor. You will have tons of power and run time, great reliability, and smooth throttle control.

This is proven winning combo.

Hey Rick....

these LRP X-12 motors are new to me. They only had the X-11's out when i checked on all this stuff before. What's the difference between the X-11 and X-12 motors? I think it may be a choice between the LRP and tekin setups for me....but who knows?

Hi Jeffro503,
The Tekin RS Pro with Redline 7.5 is awesome for performance, and handling. You would like the Tekin RS Pro for smooth acceleration, and braking. Plus its small. With not so much room to fit everything on a B44 chassis, it works great for that. The Redline 7.5 has excellent power, and speed you would like.
