The RTR 8ight comes with just grease in the diffs so it would be best to change them ASAP. I am about to try out 5/10/2 on mine

the mm at 150 really doesnt bother me, especially in race conditions, and with only one fan, i might think about putting one on the bottom of the case also

Takedown 07.11.2008 07:42 PM

150 is getting up their. Ever try running a cap board?

Takedown 07.13.2008 07:27 PM

Just got my custom delta 5 rewound 600xl in the mail today. Looks like its going to be the perfect motor for the 8ight on 5-6s.

brushlessboy16 07.13.2008 07:29 PM

sweet! have you ran the motor?

Takedown 07.13.2008 07:32 PM

I did very slow rpm checks unloaded to make sure it even ran but thats all.

Takedown 07.13.2008 09:11 PM

Found a really good deal on ebay for two 2600mah 25-45c 6s packs "very thin" for $160. I was thinking I could run them in parallel and jump it to 5200mah 25c pack with 45c bursts for the 8ight. Once I sell the e-maxx this is first on my list for sure.

Takedown 07.13.2008 09:30 PM

Figured out that if I did that it'd be 73mm tall or 3 inches "twice as tall" as my current pack but twice as potent.

The motor spooled up and ran very smoothly during my QC tests. if it can run on a junk 40$ 100 amp esc it can run on anything. let me know how you like it when you get that 8ght rollin'

below are pics of my buggy powered by the same motor only in a 4 turn delta. its 4 teeth above stock and does 40ish on 3s 4300. 6 cells tore up too much grass and cought my esc on fire:surprised:

Takedown 07.14.2008 07:27 AM

Looks like a nice setup you got in their MTX. Ok guys I also decided to stick to 5s because I want to keep my current T2 charger. I am looking into getting a PolyQuest 6000mah 5s 25-50c Lipo pack for $310 and then selling the other 5s FP pack I have.

Takedown 07.14.2008 07:46 AM

Oh and by the way the 8ight might arrive today and if it does Ill be sure to post pics of it. Ill also be clearing any uneeded nitro part off the chassis to make room for the conversion.

Takedown 07.14.2008 05:47 PM

I am also looking into the Century Swift 600+ 1100kv motor for the 8ight. Here are a few pics...

brushlessboy16 07.14.2008 05:50 PM

Takedown 07.14.2008 05:53 PM

Getting it rewound to 1600kv delta 4 wind.:lol:

4 turn delta might get it in that area, probably more like 1750Kv. ill run it through some equationsto see how clost to 1600Kv. my only fear with that motor is it might use thick carbon steel laminations in the stator, they produce eddy currents and make it really inefficient.

Takedown 07.14.2008 11:11 PM

Is their anyway to remove that?

trev3813 07.15.2008 10:39 AM

Hmm, looks like a cool build, got my intreast. Def. watchin this one =D

brushlessboy16 07.15.2008 12:45 PM

nice TD, be home in a half hour or so... yay summer school :lol:

theres a few tricks of the trade to reduce the.. all motors have eddy currents in the magnetic field to a degree, just some more than others

Takedown 07.15.2008 11:44 PM

8ight hasnt arrived yet but I never try to get my hopes up so that when it doesnt arrive Im not pissed off about it. But Ill let you guys know when it does get here.

Takedown 07.16.2008 12:29 PM

Good news guys! Got the 8ight today and its in great shape. If I can find the camera Ill post pics...

big greg 07.16.2008 12:30 PM

cool were you pleased with it?

Takedown 07.16.2008 12:31 PM

Its in very good shape and yes I am happy it finally got here and is in the shape i'd expect every r/c I get to be in when I buy it.

big greg 07.16.2008 12:34 PM

good deal, my buddy just got an eight roller off ebay, then last night a mm, a neu 1512 2.5d, a bec, hes spending alot but in return gonna have a sweet ride

Takedown 07.16.2008 12:53 PM

Nice, I wish him luck with it! I cant wait to get mine started.

Takedown 07.16.2008 09:48 PM

Im so dedicated to finishing this project that Im going to sell both my e-maxx and my matrix to finish it in top quality!

Takedown 07.16.2008 11:13 PM

Looks great! They look so happy next to each other. lol

You got yourself a nice garage there.

Takedown 07.17.2008 12:04 AM

Im hoping to get the 8ight running here right after the e-maxx sells.

Takedown 07.17.2008 10:03 AM

Yep Ive figured it out.... Once the e-maxx sells Im for sure getting my hands on a MMM first. Then the rcm motor mount after that along with the battery tray.

big greg 07.17.2008 12:22 PM

looks good, also looks like you got the pro kit towers, get the alu. shock caps, they are sweet

Takedown 07.17.2008 12:43 PM

Ya I saw the caps are plastic... Those are going to be aluminum for sure soon.

Takedown 07.17.2008 01:10 PM

Ok here are some pics with the good cam...

Nice pics! Looks awsome on the close lines, just like your warhead did. lol


Good luck with the conversion.

Takedown 07.17.2008 05:57 PM

Thanks PB! I am really wishing my e-maxx would sell so that I can get this build finished. All I need is a MMM ESC and a rcm mount.

big greg 07.17.2008 09:38 PM

what are you gonna run for lipos?

Takedown 07.17.2008 09:44 PM

Gonna get a Poly 6000mah 5s.

big greg 07.17.2008 09:57 PM

Takedown 07.17.2008 10:18 PM
