My brushless Revo

[Finnster]

Thought I'd start a thread on my BL Revo. I based it on Dafni's and Brian's and a few other's I've seen, with a few tweaks of my own. I decided to use an Emaxx tranny (sold the rest to fund this, should cover it entirely!) locked in 2nd gear. I removed the 1st gear idler and metal input gear to remove as much rotational mass as possible. The 2nd output gear is bolted to the dog gear w/ 12.9 screws. Should be very strong, but reversable in case I blow up a bearing (vs epoxy.) I am happy to report the tranny weight w/ steel idler was ~220g, about the same as a stock Revo tranny (~220g.)

the Batt trays are made from UMWPE, nearly indestructable with the weight close to CF (1.71 g/ml vs 1.61 g/ml CF.) 6061 alu is listed as ~4.1 g/ml. They are made form 2" angle, 1/4" thick. Works very well as was very easy to mold and cut, as easy as wood. Total weight was ~100g.

I was able to flush mount all the screws and bolts onto the existing chassis mounts. The bottom side is very smooth, and the whole mount very strong. I may trim alot of material out when I get a chance, but they are light enough now they are not a high priority now. Hopefully I can dye these later.





I just need to finish the front drive shaft install, the mount for the Rx and the Esc and its pretty much done. I may or may not put all 8 screws in the tranny The middle 4 don't seem to be critical, and I wonder if they are there more for the Maxx chassis the way it ties the chassis to lower braces. I will eventually going to 1 steering servo, but its good enough for now. Overall the conversion was very easy. The hardest part was the batt trays, but even then it was easy.

I will be be running an 8xl with 14 and 16 cells. I have a strobe and will be getting the 51t spur. Does anyone have any recommendations on a pinion? They are $12 ea so I don't want to do a lot of experimenting. LMK what you think and thanks to those who have already helped me get this far! I will eventually radar this to get some solid Bl #'s.
