EMaxx/Summit Hybrid?

[Mugs]

Hi, has anyone converted their emaxx into an emaxx/summit hybrid, i.e. can race on the track and rock crawl too? If so would love some pointers on how best to achieve this as I have a few ideas, but would hate to be re-inventing the wheel.

Your better off getting both(a Summit & a Maxx), a race ready e maxx is a dedicated racing machine.

Besides the fact that the Summit is based on the E~revo chassis & suspension & not the maxx you would end up spending a ton trying to make it work.

I put a spool in the rear of my emaxx and a 2speed kit in the trans. Then I put 2 Titan 775s in it on 4s lipo and it would crawl decent, but I broke a lot of parts with the torque of the 775s and the fact I would run jumbo kongs on it. It was pretty fun though. I took all the stuff off and now it's just a strait up brushless basher.

besides crawling tires you need to raise the suspension as high as possible, I've seen pics of some pretty tall e-maxx trucks but I didn't find out how they actually raised more than stock. After that lock the diffs and gear low as possible. Generally it might not be as good as a summit but some people have been pretty happy with the e-maxx crawlers they built.

After market shock towers to get that extra lift. Also bigger tires, different springs... ect.

Waste of time imo.

Firstly, you need a locking differential. You could use the traxxas spool, but as soon as you want to use it in 'racer' mode it's going to handle really wildly, the front end will want to 'push' and the rear will want to oversteer if you put spools front and rear.

Secondly, gear ratio. You would need a very high ratio, the summit in high speed config uses a 25:1 ratio (still miles higher than the standard Maxx at I think around 1.8:1 or something around that mark) and the low speed config on the summit uses 70:1. That is a big big difference.

Thirdly, motor. If you're talking about the Brushless Emaxx with the MMM + 2200kv combo, it's sensorless. So down low, it's just going to cog. You would want either brushed or sensored.

Lastly you really want solid front and rear axles as opposed to independent suspension.

Just get a Summit or a scale crawler.
