Castle Creations QuadPack 35, 35AMP Multi-Rotor (4)Pack


Castle Creations is introducing the QuadPack 35. This pack of four 35-amp multi-rotor ESCs is equipped with three (3) ESCs without a BEC and one (1) with a BEC*. Each ESC has optimized firmware specifically designed for quadcopter and other multi-rotor platforms. Refresh rates up to 490 Hz give your platform optimum stability and maneuverability without missing a beat. QuadPack 35 comes preprogrammed for multi-rotor platforms and is recommended for platforms ranging from 450 to 650 sizes pulling up to 35 amps** and running up to 6S LiPo. As with all Castle ESCs, this product is easily programmable using the Castle Link USB adapter (sold separately).

*The single BEC supplies power for all 4 controllers.

**RC HOBBY APPLICATION RATING: 35 amps for the duration of a single 4,000 mAh battery pack with the ESC in contact with a 5 mph airflow of 25C (77F) or cooler air. Controller temperature must never exceed 100C (212F). Exceeding current or temperature ratings may damage components and may shorten the life of the ESC. Always verify system current draw at full-throttle. Decrease load or increase airflow to decrease the ESC’s operating temperature.


Continuous Maximum Current: 35A
Input Voltage: 7.4-22.2V (2-6S LiPo)
Input Connector Types: Bare Wire
Output Connector Types: Bare Wire
Length: 1.93 in (49mm)
Width: 0.88 in (22.4mm)
Height: 0.33 in (8.4mm)
Weight: 0.98 oz (27.8 g) each
BEC Voltage: 5.5V; 5A continuous, 7A peak

  • It sounds like R Lefebvre has 0 personal experience with CC and is just talking smack based on second hand info.

    You're exactly right.  I have zero personal experience and basing this on second hand info.  I heeded the warnings. There's a LOT of bad experiences.  That's all I'm passing on, is a warning that the HV models seem to fail at an alarming rate.

    Lets not forget, it was so bad they even had to recall some of them.

  • I've had one CC controller failure in more than 6 years of running them almost exclusively in planes and helis. The fault was my own and yet CC took care of it with NO argument. They have excellent customer service, or least in my case they do. My first Non-Castle ESC was when I started flying multi-rotors recently. I've had several failures of those controllers (one even had a wire that fell off before I got it out of the package), all very inexpensive models (less than one forth what I would pay for an equivalent Castle and I won't mention brand names). Non were covered under warranty, not even the one with the loose wire straight out of the package. While I payed more for my Castle equipment, I certainly received much better customer service because with the cheap stuff I didn't receive any customer service. ZIP, ZILCH, NADA.

  • I have two CC ESC'S (Phoenix ice 75A and Phoenix Edge Light 100A)  and never had a problem. I don't know if you know but CC release theirs protocol specifications: the Castle Link Live. You can find more info here. Also there is a very good communication library for Arduino available here. I have used that code in an arduino micro and modified the code a bit to send RPM and Current to an Arduino Mega using I2C. It worked really good. I then written an I2C comunication library to APM and I have it running fine. If someone want to try it just tell me!

  • Castle Creations is my preferred speed control for all of my airplanes, cars, boats, motorcycle and multicopters. I had an rc car one let the smoke out ,but I was over volting  the motor so it was really my fault. They replaced it under warranty for me. It sounds like R Lefebvre has 0 personal experience with CC and is just talking smack based on second hand info.

  • Nice features on that thing.

    I'm currently using the YEP ESC's on my helis.  Supposedly they also have a tach output, but I haven't tested it yet.

    In either case, it would be much better for the ESC to calculate the RPM internally, and output that number over I2C, rather than just have a tach output which requires interrupts running on the main processor in order to measure RPM.

  • Randy not to come off as a Castle fanboy here but the new Edge controller I tested can do RPM out.  

    "The white auxiliary wire can be used for helicopter governor gain input adjustments mid-flight, serve as an audible beacon after an “unexpected landing”, act as an RPM output for 3-axis gyros that support RPM sensors, be used as an ESC arming lock (coupon for free Arming Lockout Key included) or as a receiver arming lock. Combined with the data logging capability the Edge series of controllers offer, users can enjoy unparalleled versatility. "

  • Randy, I just happened to see that the Afro ESC's at Hobby King have I2C enabled. ;)

  • They are already up for sale at tower hobbies, 148.99 for the 4 pack.

    I like this: finally some people understood we need ESCs that can support 6S batteries. as the hobby moves forward, people are also moving to higher voltages, simply to increase their flight time and reduce the amps consumption (and thus decreasing heat generated by Ohm's law). Apart from Hobbyking ESCs supporting 6S you need to flash to get something decent, I was waiting for a ready made package I can either use for my quad builds or my octo builds. Until now I had to buy separate ESCs for my builds.

    Two questions remain : the price ? are these capable of handling the rctiger pancake motors ?
