Which EDF model for a learner?

IceMan! :shock: ……………conjures up an image of some Hairy Neanderthal, fumbling around with a club in his hand during the last ice age. :(
I’m a Hot Blooded Stud I’ll have you know. 8) Well,……………..for a couple of nights a year I am. :oops:
Very impressed with that little plane. Tell me, are all Delta winged models so stable at slow speeds? I’d expected them to be unstable at low speeds and become stable at higher speeds.
I’m looking forward to taking her out again and trying out some high speed aerobatics. Must remember to keep her in close.
I’ll keep my eye on those pieces of sticky tape in the air duct,….and look forward to a dog fight with you Mr P. :D

Happy Days:
NO,…..its not what your thinking! :lol:
I had to sit out a shower or two today before launching my little delta winged model into the Blue,…sorry that should read ‘Grey’ yonder.
Had a couple of 8-9minute flights and was really beginning to get the “drift” of this little girl. She definitely prefers to have a bit of power on in the turns.
Anyway, here she is………….not that you can see much of her. Flying and photographing at the same time in rather “Challenging” conditions is not easy.
After the second flight I picked up the model and started walking it back to the car to recharge the Li-po.
Slipped on a tuft of wet grass…….. :evil:
Lost my balance……… :shock:
Fell Base-over-Apex, (arse over tit)……. :?
Landed on top of the model!! :!:
Heard several Crack sounds…..!!! :cry:
Oh well, another little job in the workshop..... :cry: :cry: :cry:
Ron:
Oh NO :shock:
What have you done?
Definitely pilot error then?
And I was just getting interested in that little plane.
Not something I would normally consider, but your description makes it sound so attractive.
Except the falling over bit :roll: :roll:

Yep, slender delta's are typically pretty well behaved at low speed and can slow down a lot more than non delta planes with similar wing loading.
At high angle of attack the airflow comes around the lead edge and rolls into a vortex over each wing. That gives you a big stable low pressure region over each wing and allows a very high lift coefficient. Drag gets very high when flying it like this but that's helpful for landing.
Sorry to hear about the damage. The occasional crash doesn't bother me too much but it's annoying when a plane gets damaged while you're transporting or storing it!
