OS 105HZ or HZ-R

[BeefSupreme]

Is  anyone  running the   105HZ?   I  want to get  the OS 105HZ-R , but nobody has them in stock.

I have been flying one with the Pumped motor and one without. With my limited flight skills I have seen no difference. I just made sure to put a fuel magnet type pickup to limit the chance of running lean.

I run both , nothing but hassle with the R , and I can't tell a difference either , go for the stock HZ.

I run nothing but the HZR, prolly sold out due to the N7 coming out....

HZR here, and it's running well.

105 HZR in #1 and it runs great.  My other N7 is under construction and will have the 91-HZ Speed 3C.

I think if I were to build another one I might opt for one of the 91 HZ-R speed motors because they look so damn cool.  I still can't get over the power the 105 makes and I would imagine the 91 makes more than enough, too.  It will be really interesting to me to see what people are getting for flight times with the 91 vs. the 105.  My last few flights with the 105 have been quite a bit longer than I ever imagined it would run.  Granted, the last 2 minutes or so is just hovering and slow flying but I've been getting over 9-1/2 minutes.
