Battery left at field.

Thu Aug 10, 2017 9:59 pm by Andyedmead

receiver with stabiliser

Post by Ianto on Tue Apr 25, 2017 11:42 am

I'm thinking of buying a 4 channel receiver with built in stabiliser function to operate a small model (Sharkie)with my DX7. I dont know what FHSS,HCCST or FASST are. Whats the word on which Rx to buy? I particularly want a safer left handed launch when I'm flying on my own.

You will want to use a Spektrum receiver. I think the terminology that Spektrum use is called AS3X.

I would probably give the guys at Steve Webbs a call, and tell them you want an AS3X receiver that works with a DX7 transmitter. They should be able to sort you out with something that does the job for you!

Andy

PS. AS3X = Active Stabilization 3 axis
FHSS - Frequency Hopping Spread Spectrum
FASST = Frequency Agile Spread Spectrum Technology.
HCCST - High Chocolate Content Sweet or Treat.

PPS. I made the last one up....

thanks Andy, I noticed the Spektrum receiver is about £50 and there are Orange and Lemon (!) equivalents at half the price and wondered if they are any good. One review of the Orange Rx said the range was not enough at 300 yds, but that sounds OK for our field.

I flew Allan P`s last week great little machine much fun.



Andy pretty much sums it up right on the recivers, 300 odd yards seems very short range im pretty sure there will be some orange/lemon full range gyros on the market. I wouldnt worry to much about using a cheeper brand on the Sharke i wouldnt go much bigger though.

Hobby King seem to do them at resonable prices

https://hobbyking.com/en_us/radios-receivers-1/orangerx/flight-stabilization.html

SKU: 9171000238 would be the one i would choice i think. (if your going budget brand) I dont use specktrum so only going off the specs.

My experience of the Lemon and Orange and pineapple receivers from HK, is variable. I've had good ones, and bad ones. The good ones worked okay. The bad ones were only fit for the bin.

Personally, I would go with the slightly more expensive Spektrum one, and be slightly more confident that it was going to work. And if it didn't work, know that I could deal with Horizon Hobby to get it sorted (which they are bloody good at doing). Instead of having to deal with Hobby King.

I've used a few orange receivers in various small models. They seem fine but, as with any make or frequency band, pay careful attention to the aerial location to keep it as clear of other wires or metalwork as possible. The orange receivers I've used have a simple short length of wire for the aerial sticking out from the case so not all that easy to keep it clear of everything. Some are in gliders and give me no range limitation problems at all.

If it was me, anything with a medium or bigger motor or engine I would just go for a spekkie rx - the few quid is not a lot if there's any question

When I rang Steve Webb Models they said they dont deal with Spektrum anymore, the ASX3 Rx is about £75 against an Orange which is less than £20.
I have a question about the operation of stabilisers(stab.) generally. Presumably you set a stab. up with the model "straight and level"( S&L), sticks to central position, on the bench. When you launch the model it will try to achieve S&L with those controls that have been set up, and will keep S&L until a control input is made and will continue with that action until the control stick is returned to its set-up position, which includes its trim setting. If a rudder is fitted and you roll the model into a knife edge, does the stab. use the rudder as an elevator to hold the model up? In simple terms is there an algorithm in the stab. to cope with the change of function of the control surfaces in different attitudes?
Or I could try Brians piece of string.

I very much doubt it for £20 it will try to roll back to level flight

I use the orange 3 axis stabiliser unit with various spekky receivers and it works fine - its simply an add in between a regualr spekky or orange receiver and costs just a few quid. It will smooth out any unwanted inputs only and is "overridden" with any stick movements on the relevant channel. It will NOT hold any input deflections such as knife edge. Your welcome to borrow one of my units ( I have one out of a model at present ) and try it out.

That's a surprise, Webbies dropping Spektrum gear. Maybe it is to make room for the Jeti equipment they now stock? ha ha!

thanks for the offer Tim but I'm expecting a receiver by post any day now. I would like a hand in setting it up and flying, maybe this Thursday if you're down the feild in the evening.

You mean a combo receiver and stabiliser unit in one? If so this will be more like a MR flight controller I guess - never used a combo one but the setup should be pretty simple and wont require a load of seperate extension leads.
Yes Ill be at the field but not until around 6 30 and its fun fly competition night but should be able to sort you out with help ;-)
