Well, first sorry for my english, it's not my natural language.
Second, I'm new in the RC world and not sure to understand.
I have a E-Maxx 3903 with EVX2, 2 Titan Motors and 2 Nimh batteries with 7 cells each (so 14 cells?).
I would like to replace these 2 brushed motors by one brushless but would like to keep my actual Nimh batteries.
So my questions are:
1. Can I keep my 2 actual Nimh batteries if I use this brushless combo: Hobbywing Combo Ezrun WP-SC8 + Moteur 2000kv COMBO-SC-C4 ? Because in features for this combo, I may read: - Lipo 2/4S Lipo Nimh 6/12. So "6/12" means that if I add cells from the 2 batteries, I must not exceed 12 cells. But actually, I have 14 cells right?
I definitively need explanations
2. What are other parts I need? Just 3977R and 3997X parts or is there something else?
3. And last but not least, I don't understand why my actual 2 motors are 14,4V and my actual batteries are 8,4V? Because 8,4 x 2 = 16,8v. How it's possible that my Titan 550 work fine with this?
Thank you in advance for advises and explanations you could give it to me.
