| Futaba HPS A700 or CB700?
Hello guys, instead of waiting next X months for HH SHV500V3 I have decided to buy Futaba HPS servo. I have been waiting too long for SHV500, mayby 4-5 months, and they are still not available.. or they are but very limited quantity, no chance to get one.. I like HH products, but.. I have Traction Hobby Founder 2 (8 kgs), what version of Futaba you would prefer? A700 or CB700? I know the difference on paper, but.. they are available, cheaper then SHVs and they are awesome for sure.. thank you!

I'd choose A700 of the two. It is fast enough and you don't need the extra speed in a crawler.

| Re: Futaba HPS A700 or CB700? ok thanks.. I read some informations on Futaba forum, I´m not sure if it is true or not but someone claims that CB is surface servo and it could be better option for cars because of more impacts, vibrations,... I´m not sure but maybe is CBs construction different from A700 which is developed for plains = less vibrations, imapcts,.. I still can´t decide between SHV500V3, HPS-A700 and HPS-CB700 all are excellent..

I haven’t tried the CB700 but I have 6 A700 in 5 different cars and it’s by far the best servo I’ve ever used.

Both the CB700 and the A700 are great. Do you want more torque or more speed?

VMGontheRocks I don´t know:-D I think CB700 is strong enought or overpowered too and very very fast but is A700 slow? I know the values on the paper but I´m not sure if I (amateur) can recognize the difference of 0,6 s:-) only A700 is for 17USD cheaper here than CB700. | ||

As far as I see the HPS 700 is a HV servo up to 8.4V and it pulls 70kg...if you plug that to your HW1080 that thing will brown out in a heartbeat without a BEC....but its your money, brother That monster servo pulls easily 8amps and the ESC can only handle 3amps(at 7.2V) Last edited by themountain; 06-27-2020 at 03:33 PM. |

Futaba doesnt recommend a BEC for the A700 in an aircraft but on the surface it is a must. I have to use a CC bec 2.0 because it’s the only one that has enough amps for the A700. It’s power hungry!!! The CC WP bec will probably work as well but have never tryed it.

The A700 is very nice. Just make sure you have a Castle 2.0 BEC. The CB700 looks like takes less amps so it would probably be fine with the normal BEC. No matter what futaba say a BEC is fundamental!!! You will also be fine with the HH option, if you can find one! If you buy it in Europe let me know where! =D |
