RE: Giant Super Sporster engine....
I do love Zenoha's. The DLE30 will have a lot more future as far as upcoming airframes. If you have access to an existing 38, fill your boots! But to buy a new one, will have a limited future. Magneto engines will prove to be a scratch builders choice.
And as stated, the DLE30 is lighter, and as strong. Enjoy your hobby.
