134mph is impressive when you look at the small circumference of the tires!

I didn't think of that. I wonder how many rpms the tires was turning. :002:

Somewhere near the 25k, if I'm not mistaking.
You think its possible to do a 100mph speed run with my RC10L3T car?
I'm thinking about using a 1920/14 with 6s and a Schulze 149.18.
What do you think?

Yes it it very possible. A local oval guy mike boylan ( puts on the snowbirds every year) use to have the world record at 95 MPH. He was useing either a rc10 L2 or L3 pan car on 9 or 10 cells with i belive a 9 turn hand wound modified. This was in the mid to late 90's , before brushless & lipo. They did the speed run in a velodrome.

Then, there's no need for the 1/8 brushless converted Mugen MRX-4R onroad car, though it's gonna be very durable in comparison to the RC10L3T.

Very impressive indeed! And yeah, I would love to see those tires upclose when it's flying like that!

I think i would rather have the converted MRX4 car in stead of the pan car. I think it would be more stable & easier to handle, plus you would have more tunning capability on the mugen. You have to remember they use to do the speed runs in a VELODROME. If you dont know what a velodrome is it is a banked concret oval that they race bicycles in. They use these in the olimpyics, they are real populer in europe & south america.

Hmmm..I got you.
A Mugen would cost me something like $1350 and the RC10L3T, which I already have, to make it ready for a real speedrun would only cost me something like $600-700. Quite a difference in term of expense.

has anyone thought about breaking 200 by doing like 4 lehners with 4 quarks with 5s on each quark on a drag strip using a street car like modified 1/8 scale street car can you imagine the speed.

They did a 200mph in a dragster( I think?) tied to a post with a rope. It was NOT funny at all.

I think I've seen that one. It was a gas car though right? IIRC, it looked like a large cigar with wheels. The motor started out with very low ropms and slowly built-up to the top speed. It was crazy watching how fast it was going. Imagine if that rope were to snap? From car to rocket!

IMO, that was cheating though. A tethered vehicle going in circles is simply a motor with no controls. Much more difficult to build a real R/C speedster...

I agree brian, let it go with some control and see what happens.

So is there a consensus of which is better or more efficient? NEU 1515 vs Lehner 1950 (or 1940)?

Or is it still primarily a difference in "feel" of the motors strong midrange torque vs strong top end performance?


I'm still leaning towards the NEU.

I think Mike carried the best motors available in the market and the choice returns to you in the end. You need the best in quality and design, the Lehners are alaways my choice. You need the supreme in effeciency and torque, the Neus gives them to you. Both have their own + and -, but I guess the Lehners are built to be a universal motor, unlike the Neu, which seems more suited to flight applications than car requirements.

From what Mike told me, they are same quality wise. Same efficiency wise. He said he was really into the Neu motor lately though, never really said why...
I would THINK that 2 pole motors would have a little better torque band, but i just don't know anything about the Neu. They are just too Neu to me. :005:

Personally, i would rather have a Neu motor, just my opinion. I like the look of them.
