Difference between 20120 and 12020?? - RC-Monster Forums

Sorry to dig up this old thread but tax return season is upon us and I am just about ready to buy a BL motor and ESC. Plus, I still have a 5% coupon to use. :)

At first, I was looking at the 9920, but since the 12020 and 20120 both are capable of 120A, I figure they would run cooler if I didn't use them close to their full potential. The ESC I get will be going into an E-Revo and it a bit on the heavy side (a little heavier than a Nitro version I'd say), so there will be more load on the motor drawing more amperage. I know the ESC I pick depends somewhat on the motor/winding I use. Aside from that, would the advantages of the 12020 have any effect on my heavy truck? I don't want to spend an extra $120 for features I won't use, especially since I was planning to use a 9920 initially, which doesn't have the added features either.

For the BL motor, I was looking at a 1940, but it's just too pricey. Price-wise it's between one of the Lehner basic XLs or the Wanderer XLs. I currently have a 2 speed e-maxx tranny on the Revo, plan to use 12-14 cells max, and would like a top speed of about 35-40mph max in second gear with strong acceleration (first gear can be whatever speed). I'd like about 10-12 minutes run-time on 12-14 cells of GP3300's if possible. This is mostly for bashing. That said, I was thinking of the Lehner basic XL2800 or the BK 6XL or 7XL.

Which BL motor would be the better choice for what I'm looking for? Then, which controller would be suitable for that motor? If the 9920 will work, fine, but I want something very reliable and do not want to run the controller close to its max rating nor do I want to stress the motor.

Thanks in advance!

I would reccommend a wanderer XL over a BASIC XL. For 12-14 cells a 7XL would be a good choice, although if it were me I would look at possibly an 8XL (will give low temps and long runtimes - easily over 10-12 minutes, maybe 20). Controller wise the 9920 could handle either of these motor on that cell count with ease.
