Council to improve performance ....

[Lucariel]

My set up is:

MMM

Align xl600 1700kV

8s1p A123

kyosho ST-RR

I am very satisfied with the performance but I would like to go some more strong ....
I thought about putting a medusa 36-80-1600 or 2000 what do you think?

the align 1700 and the medusa (80 or 70) 1600 are to similar performance?

batteries (A123) resist to 36-80-2000?

How about a Neu 1515/1.5Y (1500kv). Should perform great in the same setup now and provide more power.
Otherwise, try a Neu 1521/1Y (1577kv). This is a bigger can and will have even more power than stated above.

The align motor has plenty of torque, but does spin up a bit slower than a 4 pole inrunner like a neu. I have a feeling that you would notice a fair difference if you went to a 7s2p a123 setup, and ran a 1515 2.5d. I have a feeling your 1p a123 batt is dropping quite a bit of voltage under load. Plus 8s a123 is a bit much for the MMM.

Are you running 8S on a MMM? O.o

8s a123 = 28.8v fully charged, 26.4v nominal. I can imagine the load he has on it is pulling the voltage down pretty hard... The voltage drop is most likely what he can feel.

I ran a 600xl on 5s lipo. It worked well but when I switched to a 70mm Medusa the improvement in torque and speed was HUGE. It's like Linc says, spin-up is noticeably slow in the Align motor - because it's designed to turn large rotor blades! When I switched again to a 1515 2.5d Neu, the power is about the same as the Medusa but with much lower motor temps.

Save the in-between step and go straight to the Neu!

Indeed, 7s A123 is the maximum allowed by the spec- if that esc were to diw, it would cost $$$ to replace out of warrenty.

I would say the medusa 36-1600-70mm would be plenty of motor, but like as has been said, you need a 6s2p or 7s2p setup to get the best power and performance out of the setup, A123s aint all that great in 1p configurations unless you are running a high voltage setup with a low kv motor- 10s and 1100kv for example..

many tanks......
can you recommend where to buy a neu.....for best price? in italy is more expencive

Mike has good prices.

Steven at OSE had the smooth cans at good prices as well:

Impaktrc as well.

Good luck with shipping tho!
