RE: EDF Kits suitable for turbines
The HK fiberglass MIG-15 flies great on EDF. Mine weighed right around 7lbs before I dumb thumbed it into the trees. I got a new one but the paint on the wings is not sticking very well to the covering. Also the internal formers are not the same so it will be alittle more work to get this one in the air.
But I don't think any of the HK EDF kits will be suitable for a 15lb turbine. They would really only be good for something like a P20 or a kolibri turbine. You need to look at something from Yellow, Jet Hangar or Century Jet.
