They did tell us while they were working on the MM that a MMM version was in their future plans, but never claimed it was anywhere close to being a reality, prior to the release of the MM. Since then... yes we've been waiting.... and it seems like years sometimes...

I think what they were working on and what they had talked about as "coming soon" are 2 different things. I think its fairly obvious at this point that they weren't working on it until after they released the MM.. But I seem to remember the MM and the MMM "coming soon" announcements being released at around the same time if not even at the same time.
In my mind "coming soon" means 2-3 months... not 2-3 years.

I'm not trying to argue with you here, but you have to admit, CC put their foot in their mouth pretty far on this one. Its very obvious that they started talking about it WAY before they had anything solid.

OK, why do so many threads around here seem to migrate to a MM discussion lately?

cmc, I am with you on this one. Based on their track record on this product, I would not be shocked if the MMM didn't come out for a while yet. However... at this point, if they are saying it will be in March still (its March now), they had better not have their heads stuck that far up their backsides that they miss it by months. If they did that, it would border on the ridiculous and whoever the project manager over there is should be fired. I know my company would not tolerate missing dates by that kind of margin without some people being "held responsible." Especially such a high profile project.

I don't think there was any "MMM coming soon" stuff until after the MM was out. They did mess up by putting that on their site like in the fall of 06??

Anyway.. yeah things get sidetracked to the MMM pretty easy huh? LOL

Back to the 777 SP2:

I should dig up some old pics of my 777... it has a similar layout, sorta. The motor is up over the center diff like this one. I always liked that....

Ok, I finally finished the buggy this weekend (I was mostly waiting on the batteries and a few small parts).
Final Weight: 9.34 lbs ready to run (I know it is heavy, but the buggy is still fast).
Batteries: 2x 2S 10,000mAh Maxamp (couldn't pass up the price per cell)
Motor: Novak HV4.5 w/ HV-Maxx ESC

Hopefully in a few weeks the 1/8 track in my area will dry out and I can show off my RC, assuming that I figure out how to drive this thing properly.

How about a shot from the other side? :)

Body on or off? I can take a pic when I get home (not for another 6.5hrs). Just let me know what you are looking for.

[neweuser]

Naked of course!

K
I will do my best to remember when I get home tonight

[neweuser]

thank you! Nice job by the way...

here is a pic of the other side, let me know if this will do

Nice job- I see you made good use of all the available space

The motor mount idea is rather clever makes for good weight distribution.

Speed update!
I just ran 7 passes by a 100ft section of road to calculate top speed and after eliminating the fastest and slowest time my top speed is........
44.2mph with a standard deviation of 1.7.

here are the detail
tires: worn out dirtpaws
gearing: 10t thunder tiger (e-raptor) pinion & 46t sur
motor: Novak HV4.5 w/ 5mm shaft
batteries:2x Maxamps 2s 10,000mAh lipo

In all I took about 10-15 runs, messed up the stopwatch on a few, forgot how to drive for a few ect. In the end, the motor was only slightly warm, the esc and batteries were room temp.
Sunday I am taking it to the track to find out how long it can last without thermaling (and to see how badly I drive)

what kinda runtime are you going for with 10,000mah lol

Long enough!
Honestly, I have seen a few times at the track I race where they have made one class run their second 5 minute qualifier and then run a 20 minute main 5 minutes later.
I wanted to make sure that I could get 25 minutes of racing without being out of battery.
Hopefully, in an ideal world, I will find that these batteries do last way to long, and I can get a pair of decent 5000mah or 6000mah to save on weight, but since the cells were cheap, I figured I would go overboard first and then, if I can, go smaller, instead of going to small first and not being able to run.

Went to the track yesterday...
Not so successful.
I had a few motor mount screws come lose which allowed my spur gear to strip (plastic spur).
Fixed that and then cracked the ball cup on one of the front CVDs. I bought the CVDs off of ebay from China, so it is likely they were poor quality, I ordered a new set of fronts (stock kyosho this time).
assuming the parts get mailed today, I should get them be Wednesday, and I will take it out to the track Thursday.
In terms of performance (for the 5-10 laps the buggy lasted) it seemed on par with the Nitros, I was trying to be cautious as to not break anything. I let a nitro guy try it out (I wanted his opinion as to performance) and he was in no mood to be cautious (both broken parts were from him).
Hopefully Thursday it will be more reliable and I cam come back with useful data (motor temps actual competitiveness vs nitros) ect.

That is a cool buggy.
