The Libelle DLG by Dream-Flight - "Say hello to my little friend"

A friend of mine recently introduced me to DLG planes and while I haven't had an opportunity to fly one yet, they've certainly caught my attention and I've now watched many hours of YouTube video's and read my fair share of blog posts & reviews.  Sadly there is only a small following in my neck of the woods and local information is at a minimum.

My friend jumped in with both feet and purchased a nearly new Blaster 3.5, truly a work of art.  This was no small investment and soon enough it was determined that while his Spektrum DX6i is a great little radio it just didn't provide the flexibility and mixing to really do right by the Blaster.  This led to more research, a quick trip to a semi local DLG event for an experts opinion, and finally a new radio, the Taranis X9D.

After seeing the Taranis, it only took an hour for me to be convinced that I too needed one.  Mine is currently on a truck somewhere in the Mid West headed my way. I hope to be configuring it by the weeks end.  Now it just needs a new little DLG to fly, which brings me to the Libelle by Dream-Flight.

A little background first..backing up one week, we find my friend at the local park ready and anxious to fly his new bird.  I wasn't present at the time but I have received all the gory details...we've all experienced the walk of shame (caring the pieces back to the car, head hung low).  The plane is likely repairable but due to the hollow carbon wing, it will be challenging.

While the situation was a rare freak circumstance (he is a very talented pilot) it caused me to question my plan to plunk down 6-800 on a new plane, or at least not right away.  So the hunt was on for a less expensive option that would still give me some experience learning to discus launch.  Enter the Libelle ($120).  From what I've read, this should be a very good inexpensive entry into DLG.  While it won't compete with the big boys, it will give me the courage to get out and fly, and hopefully often.

I expect there is a Blaster, Neos or Snipe on the horizon for me but hopefully some time with the Libelle will lessen the learning curve.

More to come, as I'm still watching and waiting for USPS to deliver my new toy.

FrSky X9D Taranis - ACCST Digital Telemetry Radio



My order is in...I should have my new X9D by the weekend.  I've tried to support open source solutions whenever possible throughout my career, and figured it was now time to do so with my RC habit too. 

I opted to to go with the X6R receivers due to my new Libelle DLG's space requirements.  I'll be sure to give a little review within the next week or so once I get my feet wet.
