I used to have the old extreme Flight yak 54e and that had a similar 'fall out of the sky' issue if you came in dead stick and tried to stretch the glide. I put it down the the big radial cowl acting like an airbrake.
My current crop of 3D planes fly very differently and can be stretched on the approach quite well with no nasty sudden stall (unless you really provoke them). A slightly forward CG does also help make landing approaches easier, rearward 3D friendly CG takes some getting used to.
Shame we didn't live closer, it would be interesting to compare notes on the models you could have a go on the sticks of my Edge and Laser and see how they compared to the Yak.
How is the Yak at harrier'ing? I can harrier ok but I'm still working on my hover. There is no shortage of power, the Edge only weighs 3.25lb but has 8.8lb of thrust!.. Just lack of skill and over-caution on my part . I should really get myself a small cheap foamy to practice.
