Question
New Hurricane Owner With Questions?

Hello All,

I have just recieved my new Hurricane EP550 from Taiwa (wattupsrc).My next step up from flying the trex450.Would appreciate if someone could answer the following questions below as i am trying to get a better understanding of electronics on this next level of heli.

ESC / BEC HURRICANE

1) Is this correct the following ESC comes with a Bec?(pic attached)
2) If so is this good enough for non hard core flying?
3) What is the recommendation for an external BEC if it is'nt and why?

SERVOS / REC

1)Can some please recommend a good mid range servo for the hurricane?
2) Do you need all digital servo's or just 1x for the tail is enough for non hard core flying?
3) I am currently using a JR X2610 radio with Jr reciever RS77S ,is sufficient for a heli of this size?

Appreciate your response guys !

Cheers,
Watts2005

Watts2005,

You might want to check this thread,
http://www.rcgroups.com/forums/showthread.php?t=607690,
for tons of information on the Hurricane and I do believe, in fact, that all your questions are answered in the thread.

However, if your kit is a recent one then your ESC probably does not have a built-in BEC and you should have received a separate BEC with your kit.

And the Hurricane EP550 in its stock configuration is excellent for just loafing around yet can do some of the basic stuff, loops, rolls, and such.

Good mid range digital servo would be the Futaba S3151. Economical and perform quite well. Why skimp here and get regular old servos.

For the tail you definitely want digital and the sort of defacto standard is the Futaba GY401 gyro and S9254 servo.

The nice thing about this heli is that you have lots of choices. Not sure where you got yours from but ReadyHeli.com is very active in the Hurricane market and are working on quite a few nice mods.

Hello WATTS2005.

The ESC which you have is without a BEC. You need a seperate BEC.

Mild 3d will not be a problem even with the normal model (without any upgrades).

I am running mine with normal servos.

The 2610 is just good enough but I am not sure if it has the gyro sensor adjustment for GY401.

I ordered mine from Infinity Hobby and it also came without a BEC. I'm using a spare 3A Align BEC that came off of my Trex 600 when i fitted the new Align 6A BEC, it should be more than up to the job as it managed for 11 months on a Trex 600

I still run a regular 4 cell pack on some helis. I like BECs when run off the main pack. I can't see the reason for a separate rx lipo pack and a BEC for that??????????
