Well, we are just pointing out the truth when we said that you likely wouldn't get sponsored. This is just too expensive of a hobby for companies to be giving away $200+ things to people that are *trying* to go fast. What would happen to the company if you didn't hit your mark? If you manage to break the speed record without sponsorship, some companies would be more likely to sponsor you.

We didn't mean to be rude, but only to tell you what we consider to be the truth.

You really dont need to get mad like that. We've only wanted to put out our point of view and share our ambitions with you, however, if you want some real speed record then go for the Lehner 1930/4 motor with 20150 controller and 12 cells. This will carry you up to the world of speed you're loaning for. And you are always most welcome here.

@ doah.

Perhaps we got off on the wrong foot,

But the fact that you started this thread with asking for free stuff, just out of the blue, probably got me on the wrong foot too. If you want to have it for free, what's the use of explaining what motor to get? because it's not going to happen. I was starting with the batteries, (which are much, much more important than a motor, because with improper batteries a BL motor can't preform. those lipolys was a no-go in your own opinion, because lipolys, you said, didn't have the potential..

I thought, when you can make certain statements, and not even replying my posts, then why on earth should i boughter? i am willing to invest time in anyone here on this forum, but it must be a two way communication.

On this board i am not used with people asking for free stuff, they only come here for proper advice.

But to give you an answer on your question;

the 1930/5 (hiamp) would get my vote. it may run at 65000 rpm (hiamp version) his kvrange of 4184rpms makes it able to power it at high voltages. The controller i advice with this little powerfull thing is a 20120.. But we won't give it to you.. You need to buy it.

If you ask Mike, i'm sure he is willing to arrange something with you, but it certainly won't be for free..

I would like to have a reply on this post by you Doahh.

Would anyone else please keep their peace untill Doahh replies?

Yes i under stand it won't be for free
Thanks for that motor/esc suggestion and i might be using an HV-Maxx on it's 14 cell limit and that gives me 73920 RPM's

Batteries i'm probably using some king of GP 33/3700 batteries matched/zapped and at 1.19 volts

I'm also probably going to build a bump box so that i don't loose voltage climbing up this stupid 3 story camera tower
I'd have someone i know run out with it clip on the clips and get that pack back up to it's whatever volts

Sorry to burst your bubble here but a hv maxx won't get you anywhere near the speed record. You'd need something with more powah. And some lipo's.

I hope it works out for you doahh. Keeps us posted. Remember though. Things on paper don't always work in the real world. If you know what I mean. Good luck.

"Sorry to burst your bubble here but a hv maxx won't get you anywhere near the speed record. You'd need something with more powah. And some lipo's.

THis motor has more RPM's AND torque so i could overgear it more.

used to moving this:
Weight: 8.3 lbs (3785g) without batteries

when now it's moving a 1.5 pound car without batteries

lets say the 14 cells weigh 3 pounds
The HVMaxx system moves this 11 pound thing at 60 mph with the right gearing

Now it's moving a 4.5 pound object and it could be way over geared because these are just short speed runs and this weighs less than half as much as the motor system is used to

@doahh, please do understand that this KV range of the hvmaxx is without any load.. the voltage will drop too.. It will not run at that high RPM, a light emaxx weights about the same, and the absolute topspeed of that hvmaxx is limited, due to the 450 watts it is able to push out..

Get a 8XL and a 9920 for the same price, and you are able to throw out 2000 watts.. Go figure..

Sneeck wasn't very polite in his reply, but his meanings are good.. ;)

links please?

[Serum]

the 8XL can be bought from rc-monster its a wanderer (from BK/Lehner) and the 9920 is a BK too.. (Mike sells them too)

they are the best bang for the buck.. and if you are planning on using 12-18 cells you need the 7XL

here is the link to the producer of those items.

9920 controller

feigao 7XL

I can't find the 8XL on the site but i found the esc

[Serum]

if you are on their site, you can see two motors, choose the left and in the popup, choose the 20. its the XL serie, 8 windings.

How many cells do you want to use?

i figured out how to put UP TO 20 on the car so what is the max the motor could handel?

why use the XL series rather than the S series?
