I read an old thread on the H9 Edge540 this morning. I think I recall you having a Moki 1.80, or a Moki 2.10 in one of these planes. If so, would you please recomend one or the other for the Edge. I know, for example, that the 2.10 is only 5 oz heavier than the 1.80. I'm interested in doing IMAC and freestyle/3D. I just bought a used 540, and am saving for an engine. Thanks for your help.
