RE: Top Flite B-25 ARF (Tecnical, tips, suggestions)
cherrera26, et al,
Can someone please elaborate on the "bad" reviews out about the Ultimate 70 that replaced the OS 70 Surpass II. I've seen some praise of this engine earlier in this forum, corroborated by kproton if I remember correctly. I'd like to know if the concensus is that the Ultimate 70's are not worth the cost or are poor performing in general. I have 2 of them, unopened. Thanks for the clarification
