Ive just bought my self a hornet II with the brushless twister motor.
I plan to use the MS116 ESC controller with it.

Looks like a great little heli except mine was missing the swashplate but ms are sending me out one

Im very confused on what reciever and servo's to use I have a Futaba 9C controller (36mhz)
I live in Australia (Perth W.A) and im having trouble finding a mini reciever that is 36mhz.
Anyone from oz or anyware els know were to get them?

I also plan to use a gy240 or gy401 on it.
What upgrade do i need to beable to mount either on of those gyro's on it?

Also what are a good set of Lipo's to use on this heli?

Cheers!

Gy240 will be fine, maybe a small bit of plywood or CF plate to stick to the rear of the chassis so the gyro has a little more to mount onto.

Thunder Power 1320's seem to be the fave at the moment

Not sure on your Rx as i am in the UK and use a 35mhz Schulze 8ch Rx

I just bought a Kokam 910 which is rated at 15c. 73g after shortening the wires which is 17-18g lighter than my TP1320s. I'll post a comparison to the Thunderpower cells once I put a few flights on the Kokam.

Well the weather has been terrible lately, so no outside flights, but the Kokam 910 seems to have noticeably more punch than the TP1320s. Removing excess solder from the battery tabs put the weight of the 910 at 71.5g.

mounting MS116 ESC on hornet II
ive got my MS116 ESC today and I am planning connect it up to the motor tommorow.

The wire coming out of the esc is a smaller guage than the wire coming out the twister motor.

Is it ok to leave wire size as it is (ESC) it as is?
Which one do i trim to make shorter the esc wire or the twiser's wire?
is it ok to just solder together or is there a better way to decrease loss?

Also is mounting the ESC under the front of the heli ok?
I plan to put the receiver (once it get one) at the front but on the topside, ive read this can cause problems? ie glitching.

Cheers

Never , NEVER shorten the motor wires on any brushless, did i say NEVERNEVER . if you must shorten the wires on the controller are replaceable. I always use connectors b/w motor and esc, makes changeovers easier. never noticed a power difference either way.

The mounting of electronics will be determined by the balance of the heli. On some of mine the the speedy and reciever are close, hasnt caused me an issue yet . Some guys wrap the reciever in tin foil to help.

Ok, I'll bite!
Why NEVER NEVER shorten the wires??
On an AC Variable Frequency Drive (which is what our brushless DC motors and speed controllers are) you can build a standing wave in too LONG of lines from the drive to the motor, but I have NEVER heard of a problem with too short and I have never experienced a problem with my motors.

Dan , all the brushless motors i have ever seen have the 3 power wires comming form the motor coated in some enamel or epoxy. If you shorten these wires you then have to strip each individual strand to get a good connection and solder to stick. It is not a job worth undertaking. Much easier to shorten the speedy wire as it is much easier to solder new wire to the board if needed.
On many motors the 3 cables are often exentions of the windings, again not worth playing there.
