Which EDF model for a learner?

Speak for yourself Ron :lol:

Apart from a few obscenities when searching for some servos for the model, and when I found some, I then couldn’t find the correct type of servo arms! :!: the build went reasonably smoothly.
A most Excellent idea to use hot melt glue, and a great tip of turning the gun off for a couple of minutes every once in a while. Thanks guys. :D
Couple of things surprised me a little about the workings of this EDF. (Having never had one before.)
I hadn’t realized this until I came to fit it, but the motor is an out runner. The book says it’s a 3400KV, that’s 50000 rpm with a 4 cell battery. Seems a very high speed for an outrunner, phew!
Also inside the air intake, (This next pic. Shows the underside of the plane without the bottom of the air intake fitted, Would that be called a belly pan?) there are a load of servo/motor wires. I’ve taped them down as advised but I would have thought they are going to cause quite a bit of turbulence. :shock: I’d have expected a “cleaner”/smoother intake area. What do you Jet guys think?
Anyway, here she is, all finished and ready to rock and roll.
Just have to wait for these storms to end. Could be next week I’m told. OH WHAT! :evil:

My greatest fear, apart from landing, was that on take off she’d nose dive into the ground. :oops:
Up to the west ridge of Mt. Lienster I went this afternoon. My logic being that provided I could launch the Squall 3 or 4 meters away from me then there would be a fair amount of “air” beneath her wings to gain air speed in. Also, there’s lots of nice soft heather for her to land in if everything went pear shaped. :wink:
All my fears were to no avail, she took to the sky like the proverbial ‘duck to water.’ Climbed steadily and with just a hint of stick movement she turned round for a return fly past! :)
Much easier to fly than I’d feared, provided I moved the sticks gently.
By the second flight I started to be a little more aggressive with the controls. :evil:
Things learnt;………….Being only small, 26” wingspan, it’s very easy to loose orientation of the plane when it’s much more than a couple of hundred meters away, particularly against a grey sky.
With the control surfaces set to High Rate the planes roll rate is just a blur. :shock: There’s no way of knowing which way up she’ll be when you let the stick centre itself.
On full throttle the climb rate is breath taking. 8)
Oh, and the landing? Believe it or not, this EDF is one of the easiest plane I’ve ever landed. Looking not unlike a model NASA Shuttle she comes in, nose high up, loosing height and just “plops” onto the floor at little more speed than a fast walk.
Downsides?
Only one,……………..the noise! I’m sure she could be heard howling all around the mountain. Takes a bit of getting used to. But it’s all part of life’s rich experience.
(Won’t be flying this little girl in my local farmers field,………….might cause the cattle to stampede!)

Well done keith (sorry I mean IceMan!)you are now a jet pilot, so you need a call sign.
Yes you are right about the little motor, it will get hot, therefore you can slow her down and cruise about at times during the flight, this will let the motor cool down. Don't let the model get to far away, because as you said, it can become hard to see, keep her in close with low passes and big loops.
I noticed you taped the wires inside the model, make sure that the tape is good heavy tape, as within the air intake, there is a lot of pressure, and the tape could lift off the wires and go into the fan unit and damage the blades.
Anyhow, enjoy flying the jet and we can have a dog fight with my mig15 the next time I am down at big L.
