West Wings Skylark build thread
angry_muppet:
I've started assembly of the fuselage this morning which has lead me to consider the next things I need to order so that I can have everything to maiden her when she's finally complete.
I already have the servos and a Spektrum 6100e receiver. On the subject of the receiver, I have read that the reliable range of the 6100e (classified by Spektrum as "Parkflyer") is of the order of 700ft (or around 200m in these new fangled measurements :wink:). I already have one in my wing and have had no issues. As the Skylark is balsa and I've invested the time to build it, I don't want to risk a brown-out... Would I be correct in saying that 700ft is about the normal distance on the slope and I'd be stupid to risk flying at the limit of the receiver? Suggestions on a reasonable Spektrum receiver at a decent price are welcome.
With regard to the internal space for fly'y related stuff, the dimensions are approx 45 * 45 * 160mm, mostly in front of the CoG. Turnigy have a nice light 300maH 2S LiPo (http://hobbyking.com/hobbyking/store/__36220__Turnigy_nano_tech_300mah_2S_35_70C_Lipo_Pack_EU_Warehouse_.html). The question is, does this need a UBEC to connect to the receiver, and what's the best connectors for this?
After that, I think I have everything I need! :D

Fuselage taking shape...
I'm hoping she's square! :shock: If not, she'll be a handful! :oops:

Depends, up to 1.2 metres that I expect to be throwing about a bit - park flyer rx, any larger and it gets a full range RX. I've some bits for a 1.5 m span thermaller and it will be getting a full range RX.
I reckon that around 1.2 metres for a glider (e.g. quark micro) is the limit as I'd not be able to see it if it went much more than 100 metres out, well, not enough to control with any precision (ahem).
I drop that further for power models as they tend to be bigger in cross section, and in general get flown further out (in my experience anyway)

Hi muppet (this will never get old for me) a 2 cell lipo will put out 8.4 volts at a full charge which will likely fry.the rx and servos, most will only take up to 6 volts. also 200 mah is quite a low capacity and probably wouldnt last a whole day flying. my personal preference is to try and use as big a battery up front as it needs to balance and save putting useless lead in there. an 1100 two cell should fit in there (will post measurements of a pack later) and a small ubec or sbec to step down the voltage to 5 colts. alternatively you can use an nimh pack which outputs voltage at 4.8 volts and skip the ubec but i have never used one as they are imo fiddly to charge and useless for powered models.
pls excuse typos as on phone.
edit. also save your money and go for a low c rating pack unless you will be using it for powered flying.
