DG-303 HF-Modell all-moulded

Recommended Posts

Phil.Taylor

Time to finally get started on this one - dug it out from the workshop today to see what I've got - bought last year with the Nyx F3F

"Garden fly" - first time I've actually put it all together - see pics

Its 3.3m span - which makes it 1:4.5 scale - same as my Swift S1 - nice size for transport - F3F-sized

HQ 1.5/12 airfoil - low camber so should be good for aerobatics - as per the "Elan Acro" name

Don't know what servos are in it - haven't started digging yet - elevator servo is in the fin but no access. May remove the factory-fitted retract unit & servo to save some weight - will never get used anyway 

Mostly in pretty good non-crashed non-repaired condition - but the one big problem is the colour - or rather the off-colour - its been owned by a heavy smoker / pipe smoker - its well beyond "antique white". I've decided to fly it first, then think about respray - or not - may just add some stripes to cheer it up a bit

Some info I found

and a video of one flying - shot by Mike E

Nice one Phil. That’s some advanced paint death you have there. That retract doesn’t look straight forward to remove either with all that stuff mounted on it. Still for man of your ingenuity.

First investigations - wing servos are Hitec HS81mg for ailerons  & airbrakes - wouldnt be my first choice for ailerons but ok to get it going.

At that weight it’s going to need a good chuck into a decent blow. Should be quick though. HS 81s on ailerons? I’m with you, HS 85s or better.

a happy couple of hours this evening - scrubbing !

its a shade lighter - more of a "Olde English White" now - but mostly, the awful stale tobacco smell has gone (at least on the outside)

started with T-cut - too much effort for not enough impact, then sugar soap - didn't do much, then on to the trusty Tesco Cream Cleaner - did the job - good on tea stained teaspoons too...

also, had a rummage in the spares box & came up with a couple of Futaba 3150s - will replace the HS81s on ailerons

Good question - all that grime must have weighed a few grams!

Minor interlude from removing kitchen unit skirting...

Wings now 755g each - didnt record what they were before - seem to remember 756 & 757

Reason for removing kitchen unit skirting - to remove the tiles 😊

Happy joy - theres old 1970s tiles underneath, so the 90s tiles come up without too much of a fight (mostly) - I think fake terracotta is fine, someone doesn't so they are coming up...

And back to the DG303 this evening...

Stripping out, stripping down - the strange tower-of-power servo mounting unit was fixed with just 1x servo screw - and 2x pipe-clip things - then the retract, nice piece of engineering, well mounted (factory fitted), 4x bolts & out it came. That's 180g weight saved, plus 40g of aerotow servo - thought it would be more like 300g but every little helps. Then the lead shot & chippings from the nose - bits kept falling out despite rubbery stuff holding most of it in - 460g - big lot - hopefully it was nose heavy & doesnt really need that much. General internal tidy-up & the servo tower went back in, just with the rudder servo. 

So - its all looking much more promising now 😀

Phil.

So you’re down to 3.307kg (about)? Sounds almost flyable!

Hi Phil

Hence the age-old saying - "weight equals penetration plus smoothness leading to improved scale-like flying" - finestkind!:thumbsup::yes::) - so don't remove TOO much!

Here's to s-m-o-o-t-h flying from now on......

Regards

It will get another aerotow release servo for "Devon Glider days" - but that patch is just a wee bit too bumpy for a retract !

Hi wookman and Phil

For me, slope soaring is the perfect way to fly scale models

Personally, I think that If you winch or aerotow scale models you spend far too much time as a dot in the sky

If you fly from a hill you can fly your model close to you, admiring its lines, scale detail and flying qualities  and, so can others watching your model. No eyestrain, no neck craning and clearly hearing that lovely hiss that a well-trimmed scale model emits

There's no need for onlookers to ask you "What is it?" You only have to point out the name on the nose...….what's not to  like?:)

That DG303 will look, and sound, gorgeous dolng long slow passes  with a chandelle at each end of the slope.....I used to love doing that with my MPX DG 300 as often as I could

Regards
