This is not so much a support question, but a spec question. I figured you guys might have some numbers in advance...

I am in the market for a 50cc engine (DA50 and ZDZ50NG being considered so far), but the new MVVS 45 IRS is a stunning and light piece of machinery.

Would anybody know ball-park peak rpm figures of this new 45cc gas engine on a 22x10, 23x8 2-blade prop???

How would it compare to the above established 50cc models (about 6.8-7.0k on 22x10 with pipe)? The power -and weight- of the MVVS 58 is more like that of a 80cc engine!!
