Jason said 1.5 r-spec’s, and an r-spec is just over 100 USD… so I bet you are looking somewhere around 150-160, maybe even a little more.
With just a beast single setup, you can save money by only buying buying one esc, one mounting system, a lighter board overall, and possibly have better efficiency- The efficiency point might not apply as much for this r-spec, but I’d still bet that it is better than having two original r-specs; just maybe not by much…
I’ve gone with single motor setups on all my boards, ranging from a 6s single 50mm build, to a 10s r-spec build. Now, you have to realize I’m only 16 and 140 pounds, so single motors are just fine for me- even the 6355 r-spec is fine running in a single config. I also don’ have any hills (florida life) so I don’t need to worry about that either…
The main things to take into account is that a dual motor build (despite what people say) will not go faster than if you just had one motor geared the same: the dual motors advantage is just having more torque for faster acceleration, which leads to better uphill performance, and the ability to carry more weight.
So, bottom line: If you live in a hilly area, or just want super awesome acceleration and performance, than dual motors are for you.
BUT, this new r-spec seems like the perfect middle ground between single and dual, if you are wavering in between: so if you think single would be fine for you, but you know you want more performance than one motor can offer, this might be a good option for you.
That said I think the turnigy 6374 190kv is around 80+shipping, so this may end up being close to double the price of that… Granted though the turnigy doesn’t have a keyway, the wires are super stiff, and it isn’t built to the quality of the r-specs, I still think it might end up being a better deal for those on a budget.
Basically, if you were thinking of getting a dual config, and you don’t really need it than this will save you money
if you were going single motor config, than for an extra 50ish usd you can have a board that is way better than what you’d achieve with a single r-spec- again, worth the extra in my mind.
It’s only not worth it if you don’t need it, or are trying to build a cheap board (which could backfire on you in the long run)…
haha, a lot of reading, I know… hope it helps though!
