Modded V1 & V2 long term testing
 

Hi guys,

Just thought I'd start another thread on the testing of the modded V1 & V2 MMM. As mentioned in the other thread, I did the BrianG mod on my V1 & V2 residing in a X1 CR buggy & X2 truggy respectively.

Modded V2 survived another short bashing session on Saturday.

Modded V1 had a full race day today. The weather is very cool for this part of the world around 28 to 30 deg C & but humidity is high as it had just rained earlier in the morning prior to the race. I ran both nitro & electric (modded V1) as 2 persons.

I am happy to say that V1 survived 3 rounds of 5 minute qualifying & made it to the A main (6th qualifier out of 13). However, as A main was 30 minutes, I sweet talked the race director into swapping my running order as my nitro qualified way down the order in B main. So I ran 15 minutes of B main using my modded V1. I came in second.

Sometime into the 3rd heat, the fan stopped working. Not sure what happened but I ran the buggy anyway straight 15 minutes in teh B with a non working fan.

So all in all, a pretty happy outing for the v1 :yipi:

HN drivers - but my HN nitro killed its rear diff & I had to run my backup TTR S3

Hmmm, I have just finished charging my battery. After 15 minutes of hard racing, the charger put back around 3600mah back to the battery. This means that in theory, my 6000mah battery should make nearly 25 minutes of run time !

How were your temps with no fan?

I'm all out of MMM's right now. I sent #5 back to Castle on Friday. :tongue:

I was kind of busy as I was running both nitro & electric so didn't have the chance to check. Just blast away :whistle:

Did you take the temp while running without a fan?

joe- i ran 15 minutes as well, with a zippy 4800 pack - and i only put 3300 mah into it. that means i could almost make 30 minutes! i will have to see if i can get my neu to be cooler though... it was running a bit hot! (its first race day)

Hi guys,

I did not check my temps at all, just went ahead & ran the race. Came in about 18 seconds or nearly half a lap behind the B main winner who is a much better driver than me.

if you could take some temps and report back id be very happy :)

well done- more practise is what i need to get in the top drivers. perhaps next season i can try for a trophy! :P

Ok I will do that next time. I think that will only happen 2 weeks from now. This weekend is family time.

I'm resigned to the fact that I'll only be a middling driver. I am not serious enough to study the racing line or practice nearly often enough. Instead I like to jump high & far & muck around with electric cars.

So I just go out there & have fun with the boys. Of course, I really like to hassle them with the electric conversions. :lol:

BTW, don't forget mental toughness when you're racing. It makes a big difference.

Hi guys,

2 weeks have gone by & once again i had a chance to do more testing / bashing with both vehicles :

1) buggy - during the last race, the fan stopped working. Replaced the fan with a 3racing unit & ran her for about 10 minutes yesterday. Temps were :-

a) motor 50+ deg. C
b) battery 30+ deg. C
c) esc less than 40 deg. C
d) ambient - about 30 - 32 deg C

Still alive & kicking

2) Went on to play the truggy until LVC kicked in. Temps immeditely after the run was :-

a) motor 65+ deg. C
b) battery nearly 50 deg. C
c) esc less than 40 deg. C
d) ambient - about 30 - 32 deg C

I'm pretty happy with the esc so far. However, some minor problems with the motor mesh as a result of all the hard landings.

blue locktight is your best friend!!

Hi mxracer,

Thanks for that. I already had them on the pinion grub but I really try to avoid them at the motor mount into the motor.

How's Perth, my favourite city in Australia ? Weather getting better ? Got to try out the tracks there sometime in the future.
