Project outrunner e-savage

[MetalMan]

Keep in mind that those glow "equivalents" are for airplane engines, not car engines. The engines we use in cars are quite a bit higher performance than the airplane engines of the same displacement.

I agree with Sike, those motors are too small. I was looking into a motor for my Revo, and was looking for something containing a stator with dimensions of about 40mm diameter x 30mm length.

I will put money on the fact that the e savage will be no lighter than my hacker emaxx. Listen to sike, he knows what he is talking about!

In any case, whatever the mfg says about glow motor equivalentcy (sp?), you are asking this motor to start with a heavy load. The mfg rates an outrunner with a prop. We do not use props in car (well I have!). Keep in mind the roll out of the gearing and the load imposed on the motor. Not to mention the voltage and current spikes thru the esc.

JRH made a good point with motor weights. Plus you need a decent sized lower kv motor to make this work. I am seeing that 4s is just not really the best way to go with outrunners. Motor voltage, lower kv, and less amp draw makes for a better system, inrunner or outrunner.

An electric vehicle will weigh slightly more than a gas vehicle, if you intend to reap the benifits of electric (longer runtimes). I am sure that you can find a good 25--30c lipo in the 2500 mah range that will give you comparable runtimes to a single tank nitro run, and weigh in similar.

I mailed out the draft anhd everything for the guy that is making my custom motor plate. No turning back now.

I received my motor and rcm couplers (Very impressed with the quality of both pieces), still awaiting the mount. Here are some pics.






(The motor on the left is the ammo motor I was using before this whole project.)
