If anyone else was wondering about installing a 1717 in a E-revo BL, i thought i could share some pics :)
I ended up on a 21/40 MOD1 gearing with a castle pinion, and a Revo spur.
This gives me 44mph on 5s/29200rpm`s@3.7v, or 52mph on 6s/35000rpm@3.7V, on MT badlands (5.84"). (using LST XXL diffs)
I`ll do some more testing on temperatures and come back on this, since my lst diffs lasted 10mins the last time i tried, and now i`m waiting for a new MMM ESC since my last RX8 went up in flames.
I dont think it`s possible to fit a smaller pinion, without raising the tranny alittle.
I must say, i`m kind of sceptic about temps for the MMM esc with this huge motor, but we`ll see how it goes. I know people has done it before, but i dont know about theire temps.
In this first pic`s, i wanted to show that i`ve shaved off almost 2mm of the entire motor mount.
Of course i had to shave the same amount of where the lower mounting (pivot) is..
I also had to use 4mm countersunk screws, so i had to drill the bracket holes for that.
As you can see below, this made the spur REAL close to the mount (it looks like it`s touching, but i promise, its not as bad as the pic shows hehe), so i shaved off alittle there as well, to make alittle gap between them.
The pinion is also very close, but it does not touch ofcourse.
I actually cut off the motor axle 2mm because it touched the mount plate, and i shortened the wires to clean up the installation.
The rear shock mount had to suffer some :p
I dremeled it _alot_, but still as little as possible. With my 21/40 gearing i actually barely touch the rear of the motor, and the motor is approx 1mm from resting on it under the motor.
BUT i have moved my tranny 1-2mm backwards to fit the front kershaw axle that`s too long, so it shouldt be this tight. I might do something about this later.
Right now, my ESC is in the mail from Tower, but i will get more pics when its innstalled.
And the stock RX box will be used, in the stock mounting place.
