neu 1512 2.d/f hyper st pro truggy 52/12 gearing mamba max , 15v cutoff voltage 5s flight power 4900mah everything is pretty close to the same as yours , yet i get about 9-12 mins runtime i have a jammin cr pro buggy , i will try replacate your setup as close as possible , but i very very much doubt i will gain another 30 mins of runtime HOW DO U DO IT ?? |

Somehthing isn't right. What temps are you getting ? Your driveline might be binding some were causing drag and robbing you of run time . Check your diffs , cvd's Centre front and rear ( especially the pins ) and bearings :wink: |
i have 2 brand new truggies , no binding , everything smooth as silk
got 7 x 4s flight power 4900 packs (so that rules out a dud pack) 1 truggy is MM 1515 1Y geared 13/52 motor temp 50deg C other truggy MM 1512 2.5d geared 14/52 motor temp 70 deg C both get 10 mins runtime then i tried the 1512 2.5d on 5s with 12/52 and still 10 mins . with no extra speed and motor temp 70 deg C |
Got me stumped on this one , maybe some of the experts can chime in on this . Might have to start up a new thread to get some answers :wink:

Settings?
What are the settings on your MM? Is it the same ESC you're using in both vehicles? Set reverse power to 100% and see if that helps, I had a MM running backwards, set to 50% once and it took me a while to figure it out. I don't really understand the short runtimes though.

yes same esc settings.
forward / brake only no reverse timing 5deg punch control disabled .. < maybe that has something to do with it ? start power medium drag brake disabled voltage cutoff (auto lipo for when 4s ) 15v for when used 5s im so keen to get 30 min runtimes ! we have a private rc track of our own so we just bash/race lap after lap all day |
try timing = 0
that might help but i am also a bit confused... when i saw 45 minutes i thought it was impossible? i was hoping 15 minutes+ from my 4600mah a123 cells (which can be drawn down to about 5% (according to the charger) so perhaps its not going to be easy on a large track? |
Just curious as to whether the Muggy uses the same chassis as the 8ight-T? If it does, then technically this conversion kit should work for the muggy: http://www.impaktrc.com/product_info...oducts_id=2870
Any thoughts? |
The Muggy and 8ight-t have different chassis'.

I run a 1512 2.5d in my buggy,on 5s with a 16v cutoff,running hard on my local track I get 20min's.low start power,50% punch control,lowest timing motor temps 160,mm 110,batt's come off 120 degrees F.thunder power 25c 5000mah.Also with the throttle endpoint turned down to 75% as the buggy is to fast for me on the track.
I tried it on 4s 25c 5000 tp pack,had to turn endpoint back up to 100%,cutoff to 12.5v again get 20min runtime same gearing for both 13-48. I am also running this in an 8ight. |
Had a little scare today. The other day I ran my buggy in my dads backyard chassing the dog around in grass with no body on. I went to turn it on today and saw that the fan wasn't working and there was a whole bunch on grass inside the fan and esc. Don't know why I didn't realise this when I turned it off at my dad's. I took the ESC apart and took all the grass out and started it up and away the fan goes :party: I did notice mark on the bottom of the case where the fan plugs into so I cut a little bit out just to be on the safe side. Can't wait for my days off to take it around the track again :intello:

I think you were close to the dreaded fan failure and possible bec failure on the v1 , lucky boy . |
That will get the blood pumping for sure. :intello: I’m glad it worked out for you.. Got any Vid you @ the track to share with the team (?)..:neutral:
|
My wife still hasn't worked out how to use the video function on the new camera. See if I can get 45minutes of straight action for you all :lol:
|
I'm about to do a similar conversion.. just wanting to get your thoughts on what 'spare' parts to have on hand. I have a new race roller en route, and the losi e-conversion kit (new item). I'm about 1:20 from my track so when I go that distance, I like to be ready for any 'issues'.
Thanks! Nice setup! |
I haven't had no breakages and it has been through hell and still haven't broken any parts. I have had a few guys tell me just to have spare A-arms on hand but haven't had no dramas. I would recommend though to get some skid plates. http://cgi.ebay.com.au/Team-losi-8ig...QQcmdZViewItem
You will also require thicker diff oil. http://i34.tinypic.com/ifbh3a.jpg http://i37.tinypic.com/nv5e8w.jpg http://i38.tinypic.com/1zn1xmp.jpg |
Those are the exact skids I am running. I ended up taking off the front skid, since I can't find screws long enough to hold it in place. The stock screws work everywhere except for the very front two holes that also hold the bumper in place. Other than that, the skids work great and definitely give the buggy more protection. :yes:

Well had some fun today in my backyard with it. While I was driving around my son was riding his little trike thing with a trailer. 1 thing led to another and the trailer was zippie-tied to the rear shock tower. We then had to test out how it could jump.

That's a nice shot. Looks like he really digs his Eight. I mean your Eight.
Bam I hit post and all the rest of the pictures showed up. Now those have a little more action then just the first four I saw. Looks like the trailer is pretty aerodynamic (sp). |
I only mowed yesterday so there was a far bit of grass clippings around. The buggy was covered in grass and grass got all in the MMM but the fan still works fine. Took the top off, blew the grass away and still works strong as. Temps were great to but always are when bashing around Motor - 105F ESC - 85F Battery 83F

Blew it down with Air Compressor and buggy came up pretty clean

What Neu are you running and what motor mount is that? I see you are using motor brakes as well? What do you think of the setup and what velocity are your oils.
Thanks! |
Nice action shots. You should race towing the trailer so it is fair for the nitros. :lol:

Well took it down to the track today. I changed the front shocks to a #55 piston. It was a very humid day, I was sweating pretty bad at the track. Motor temps were between 150F - 163F and the ESC & Battery was 112F. Not many pics this time. 1st picture is just my son watching me fly around the track making sure the buggy is running right (soon to be pit crew). I took the video camera down aswell but went to record and realised that the battery was flat.

what gearing are you running now?
I have the same setup geared 13-48 and my motor runs about 170-180 after 15 minutes. and my 4s 5000 pack hit voltage cut right at 15 minutes.I'm thinking it's undergeared. with the same setup on 5s temps are the same but runtime is about 20 minutes |

so what gearing are you currently running?

thanks,what I needed.
I have been running 13-48 on 5s,this weekend I tried 4s with same gearing and was slower on straight,but runtime went down and motor temps stayed the same |
good info
|
Well had to happen sooner or later. Playing around in the backyard, came in to check the temps and notice the fan not working. Had a good look in and saw that 3 of the blades on the fan had snapped off. MMM still runs though and I have a spare Novak fan sitting in the cupboard. Just got to decide what to do - Send it back to CC or just put the Novak fan in
|
that sucks,my mmm broke the fan plug off of the board already.
|
Took the cover off tonight and removed the blades. Fan still works and MMM still work fine. Thinking about trying the MMM without the ext. bec and see what happens
|
Just finished up my e-8ight using the tekno conversion.. WOW awesome! I've got the MM esc w/ fan and ccBEC (4s config). Gearing is stock spur (48) and 16t on the e-clutch. No temp issues and she runs great! Motor is the Medusa v2 2000kv 60mm.
7,10,3 for diff fluids 50wt w/ Green on front shocks 35wt w/ Black on rear shocks She runs great and I was owning the nitro's today! |
