Lol featherweight slash? how about a ofna gtp2e a 1/8 gt car no featherweight.

I just weighed my Slash 4x4 with the STRC chassis. Now admittedly it still has the stock Vilneon system in it, and the body was not on. But it came in at 5lb 12oz's.

It did come straight from the horses mouth when you told me a while back your slash weighed no more than 9lbs with 8s. Obviously its gained weight and speed since then.

Now that's a featherweight!

The cars weight WITHOUT batteries or body or whatever else is completely irrelevant! It HAS to be weighed ready to run! My mgt7e was 13lbs 12oz both times I hit 165mph! Since then I've been able to drop a pound by replacing a few aluminum parts with carbon fiber and used a lighter resin only where the body needs it rather than glassing the entire thing, it now weighs 12lbs 11oz ready to run on 8 cell! Phil, as I stated before it IS possible to run the CM2200 with really conservative gearing, the whole point i was trying to make is you're not going to get the full potential from the motor

Yes, just need a custom mount but the 2028 is so low in KV you would have to gear it to the moon or run 8s to get anything decent out of it (which is possible) but it's easier to use a higher KV monster.

165 is crazy, nice! my buggy weighs 9lbs 3oz ready to run. Of course no real body to speak of.

Nice Fdjizm! Interested to see how it goes!

I ran 49/36 gearing once on a ~900kv 5682 motor from Turnigy. The no-load wheel-speed of that gearing wasn't even that high because of low kv, but still it burnt up the stator within 2nd test-drive, as the current rating of the motor was only about 100-110A, ...due to cheap . Pics below, and for more info check the GT2 thread in my threads.

@ Nitrohead: Targetingxmod put a Leo 58110 in a 1/8 truggy: "targetingxmod" Mugen Mbx6-T 7s project; it's a cool build, but performance-wise it's nothing special (sorry Xmod ). From my experience, I'd say it's just not possible to exploit the full potential of a 1/5 motor with 1/8 battery space... I think even in a good TP4070 or similar set-up, the batteries and ESC will be more of a bottleneck than the motor. Then again, a 1/5 motor in a 1/8 does look pretty awesome .

Interesting. I don't recall seeing many guys running real fast on the big motors. I have a 4070 and am watching closely on how the guys are doing. I think it is going to be a learning and parts curve on them. The market will usually follow the performance needs if they see money to be made.
Heres a little up date on mine.

Yeah, for single pass warp speeds like the top guys here in this thread are doing a 1/5 motor is not necessary, and might even be counter-productive, as I think bigger motors tend to be a bit less efficient at lower output. Didn't even Nic Case use "just" a 40mm can Neu 1530 on his Guinness record passes? With motors like TP4070 already stressing out XLX ESCs and dipping big-battery set-ups below 3 V/cell on passes, there does not seem to be a need to go much bigger on the motor if single pass top speed is your goal.

One advantage though of a big fat motor, besides being fun to show off , is that it heats up a little slower, allowing you to run relatively high gearing and speeds for an entire pack.
