Jeff - your could save almost 2.5oz by going for a 1509 I'm sure it would still have enough torque - Also direct solder the motor leads to save the connectors - must be another oz.... That should take you to under 7...

Yea, I thought about getting rid of the connectors, but I prefer the ease of maintenance to be able to just unplug them. Also allows for easier testing of different motors. I tend to tinker quite a bit and swap motors around from model to model just to see what I get.

I do have a Lehner 1930/10 that I was thinking about dropping in to see if it could work. I did have it running in my CEN buggy for a while but ultimately decided that it was just a tad undersized to run cool enough for my liking. But that buggy was around 9lbs so I was thinking I would give it a try in this one considering its almost 2 lbs lighter. It might be perfect and would save me a little over 50 grams. Also, I used a spare EC center dif top plate that is aluminum instead of the 808 one that is plastic. Could probably save 20 grams there and then I could cut the carbon fiber steering servo top plate from the 808 and replace the aluminum one from the RCM conversion and save a little. I could get rid of the ESC mount that I have and mount it flat to the chassis behind the motor and save a little more as well. I just might be able to get there if I try hard enough. But in reality.... its already plenty light. The extra few ounces probably wont make much difference in the real world. At least none that I would be able to notice.

Jeff - how does the 808 compare to the XB8EC?

Also - they've gone to a 42T spur standard? You've gotta be up around 45-48 with that gearing at least, no?

I ran my XB8EC this weekend with the same motor battery combo of 5S on 1512/2.5d with a 15/48 gearing and clocked 47mph when the batteries were fresh.

The EC is a really nice buggy too. I still love mine. The only problem I ever had with it was it was almost too adjustable. So many difffernt adjustable settings that I didnt know where to start with it. Most of them never got touched cuz I didint know what I was doing with them. The 808 is a bit more simplified as far as adjustments. they say it "optimized" so you dont neeed all of the adjustment. This is good in my opinion. The shocks that Xray did for this buggy are absolutely works of art. Super smooth and finally threaded preload adjusters I havent driven it enough yet to really give a good opinion on how it handles compared to my EC, but the short test runs I did were definately encouraging feeling.

It uses a 42T center gear, but it uses 10/43 truggy ratio difs to make up for the taller center gearing. Its geared for around 40-42 mph now. The small center gear and offset center dif mount is an effort to move the nitro motor closer to the centerline of the chassis. The cool thing is it also allows the battery to move closer to the center.

In reality the 808 and the EC are totally different buggies. There are very few parts that are interchnagable between the 2.

Roar rules are minimum weight of 3200 grams (7.05 lbs.) anyway. Not that this thing conforms to ROAR rules being electric, but its pretty much as light as it needs to be.
