I think the 38 is a development of the 37 (which had a steel liner).<div>The 33 is a totally new engine from the ground up.</div><div>My 33 spins a XOAR 19x8 at 7450rpm  after warm up. Pulls a 5Kg GW EDge 540 straight up. Hovers a heavier plane than the DLE 30 and pulls it out of the hover with better acceleration.</div><div>The 38 spins a 20X8 at 7600....</div><div>
</div><div>Ariraptor not sure where price came in (a curve ball perhaps) so I don't know what the 38 cost in relation to a DLE 35RA but I'm guessing its pretty similar. I can't answer the "why aren't people talking about the Mintor 38 ?" question in you neck of the woods bt maybe its got something to do with some marketing principals and the number of people using them. Mintor is not as established as DLE for instance but it ver well supported by Top Dawg Avaition</div>
