Project fast 1/8 buggy on a budget

Thanks Hoov for the info and the links especially. I have decided to go with the MMM V3, almost ordered on ebay today but i need to work on my paypal acct. I will also be ordering a 8ight but just one stupid question, Do the different versions of the 8ight mean anything to me as a basher. I see a 2.0 version and two green box models. I think they are both nitro rollers. I dunno i just dont want to get something wrong.


So if I am reading correctly above that 6s should only yeild 60mph. Hmm. I mean not bad but....i dunno I was already doing that in the t4 so it does not impress me that much except for the obvious larger scale. I know the racers hate guys like me that are out for all out speed runs but like you said one more battery for normal running and im in the game. I just moved to N. las vegas and I havent checked out the scene for tracks yet so maybe some day....

Anyway I have decided on the MMM, def the lipos you mentioned (great value), Losi 8ight with conversion.

Undecided on the motor. I have read on 6s you should not go full throttle too long and Lee from CC said the 2650kv is only intended for up to 4s. Just what I have been reading. What about the Medusa Motors? Cheaper and if I burn one up it wont hurt as much. I dunno. What do you think. You did not say but have you have ran 6s on yours Hoov?

The 8ight 2.0 is the most recent one that just came out. I have the old one, so I dont know the difference between the two. I'd assume the 2.0 has some advantage/improvement.

as for the speed....Thats 67mph with the gearing set at 14/46....I just realised that the kit comes with a 45t spur...and I use the plastic 44t kyosho one...also the kit comes with 15t and a 16t pinion gears... So breaking 70+ will most likely be the case.

The castle motor is rated for upto 60000rpms. For speed runs, you will be fine....but you dont want to run those rpms without temp checks. also, you will be hard pressed to find an area you can run full throttle for very long...other than a drag strip or an abandoned airport. The 2650 is under 60k rpms on 22.2v(6s) so it should be fair game....


as for me.... yes, I ran on 6s geared 46/15 with a Tekno Neu 1515/1y. I was doing just fine until I gave the controller to DickyT. jk rich
But anyways.... The buggy was running like a bat out of hell...until the foam came flying out of the wheels. They must have ballooned to the size of dinner plates...it was insane.

Any aftermath pictures?

[hoovhartid]

other then shredded foams, there really wasnt any carnage. The wheels actually look normal, until you touch them and notice the foam is gone. There was like a 1/8" hole in each tire when I got the buggy. I assume it was to allow for some breathing room between the wheel and the tire and avoid any tire bounce. I personally drill 1/16" holes in my rims before glueing to allow for this, but maybe I am missing something that the previous owner liked better. Anyway, the foams seemed to make their way out of these small holes and now that they are out, the tire actually "looks" normal again. So, pics really wouldnt look different than anything normal. I have bought new wheels since, but no on road style, so until I get a wheel that can withstand 70+ mph, I will most likely keep my 8ight on 4s.

maybe I'll pick up some of THESE or THESE and give it another go!

thats where its at ! ... we as gentmen trying to have fun. some to tame sppeed for a track, some trying to conquer it for no reason. 70moh tires must be had. Members here have gotten us what we neen Lu esc, now we need the fat tires boys... 70mph was a wow really last year... we can all hit it with a rcm 22 tooth pinion now. Tires cant hang, Axial bead locks , TAPED, and real tight are the best ive pulled. Anyone got a foam fat monster wide style tire they can produce... $100 here

Thanks guys. Well I was looking around and I still cant decide. I mean dont you think for like $50 bucks more I should a better quality/stronger/versitile neu 1512 motor? It just seems to be the winningest choice on this forum. Then cant that motor handle more on the gearing yeilding speeds even faster then the MMM combo. I am a little perplexed. I just dont know enough about these motors or experience and I just want a really versitile motor. I have also read that more often then not the lower KV is better for options where the higher KV motor will just end up producing more heat.

Hoov I am not doubting your suggestion in any way just picking your guys knowledge. I am just one of those guys that want to do it right the first time. And I am probably wrong or am getting confused. I just cant afford two of these motors or the possibility of burning one up.

Guys you are so helpful. I am almost there and thankfully b/c Christmas is around the corner.

Oh and I need those 70 mph tires for sure too!! Also I did see someone running beadlock on a truggy is that possible. Wouldnt it be very stressfull on the rig and produce more heat.

Hoov,

We have taken the foams over 90 and they hold up! We will see their max when I get my 10S 8T back up!!

Jay,

The only problem that exists right now is that there is no tire truer to true them. There are ways to get the foam donuts to glue them yourself. I have been bugging JACO to see if they will release the 40 series foams they had a few years ago for the Maxx in a 17mm version.

A wealth of good information here for sure but let me throw in my opinion of running 6s vs 5s.....I have learned that running 5s seems to be much more efficient due to the high RPM jump when going with 6s.......the very first thing you should do is learn to use BrianG's speed calculator
http://scriptasylum.com/rc_speed/_top_speed.html it is the key to dialing in any truck.....you can get just as much speed out of a 5s truck (with the exception of speed runs) and run at a much lower rpm ...hence less fatigue and heat on the motor.....let the gearing do the work

LEARN TO USE THE CALCULATOR

As for the Castle Neu, vs the Origional Neu... the jury is still out. On paper, the Castle neu(and Tekno Neu) will be better for use in a buggy than the origional. The origional was designed for flight, so dust and high vibration werent taken into consideration as much. The Tekno, and Castle motors use bigger bearings that help with the vibration in land vehicles. They also have a sealed can to help keep the dust out of the windings. The trade off is that having a sealed can doesnt allow the airflow that the origional motor had....this generates more heat. People have reported that their Tekno Neu runs hotter than their origional did. With that said.... I used my Tekno neu in my e-revo on 6s geared to about 50mph and the hottest it got was 130F.

If you're looking for the most tried and true...you cant go wrong with the origional Neu. If you want something similar in performance and need to save some $$ then the Castle Neu would be the way to go. The motor is liscensed by the origional designer (steve neu) so it cant be too far off the origional. I mean, castle is now doing the distrubution for Neu, if anybody is "in the know" it would be them.

I'm not sure if I helped, or just gave you more crap to think about

sorry for the book. I just know where you are coming from. I too want to buy right once. This is just one of those things. I dont think any motor with the name "Neu" in it will be a bad choice, but figuring out which one is best can be a rough task.

Man you have helped me alot. Last night I was doing some calculations and studying on nues site. I very well may get the MMM combo and I also noticed that I was incorrect on the lower KV i was claiming on the neu, I did not realize there were so many versions of the 15 series neu. I am learning and for right now I will just get the kit in and started and will work on crunching the numbers on the nue and castle nue motors. You are a wealth of information and truely appreciate you sticking with me in my ignorance. Ill get there its just taking a minute...lol. TY very much.

I do however feel much more comfortable about my decision on the 8ight purchase. They are SOOOOOOOO cheaper now then they used to be. I mean its only $50 bucks more then I paid for the FT T4 kit... Crazy. I know electronics are more but what a platform for the price.

Still very excited for the build and sharing my experience on this great forum.

Now if I can get Mike to build some two piece mounts like the one he just did for the 808 for the losi 8ight.

[hoovhartid]

I'm glad to help anyway I can.

Okay well

8ight kit ordered (check)

MMM combo ordered (check)

8ight E body (check) very cheap on rcslot.com fast delivery

Paint (check)

Zippy Lipos (still need to order)

Pinion set (need suggestions guys)

quite spur (kyosho one right...link?)

Anything else guys.

Anyways, getting closer...now a little christmas prayer.

"Please god forgive for lying to my wife.....
for telling her that the MMM comes with the buggy.....
for telling her it only cost $200 total
for hiding my purchases on a seprate CC that she has no clue about
for telling her this car will never break like the other ones

and most of all for PROMISING her that this will be my last RC car I will ever buy!!!!

Please forgive me God.....Amen"

[Arct1k]

It isn't god that needs to forgive you it is the mrs...

Reminds me of the conversation on Thursday night... My six your old is annoyed because i get so many packages!
