I agree that the XF 5100 motor is excellent with the stock fan. I'm a newbie to EDF, treated myself to the Alpha Mig for Xmas last year and went with the e-flightline Himax 2015 package. The first motor was bad, and efltline replaced it. The plane flew well the first time I maidened it in March, but I was in a small field and it scared me, so I brought it in after only a couple minutes. I figured I might need a backup fan, so I ordered another stock Alpha 3 blade, and fitted the XF 5100 to it. For the last 6 months, plane and fan sat un-used.
I broke out the Mig last week for it's post-maiden maiden, and got scared at how fast it is. This time, I took it to a huge 40 acre soccer field park, but it still scared me. Fastest I'd flown prior is my GWS zero, which can hustle, but nothing like the Mig once it's on step. Tried to bring it in slow b/c that sucker just glide forever on zero throttle, and stalled it at 6 feet.....smashed nose, cracked fuse just fwd of the wings, tore loose the fan assembly. I'm just not used to having to keep up that amount of speed on landing to prevent a stall. Guess it's a swept wing thing. Whatever...turns out that the Himax is toast now. No idea why b/c it was off on crash landing, but once I had everything glued back together, it causes the Phoenix controller to cut out at anything more than 1/3 throttle. There's no binding or rubbing I can tell, so seems the motor is bad.
Sooooo, I fitted the XF powered fan and using a 3c lipo, it screams at a definitely higher pitch than the Himax. Took it out today and it practically leaps out of my hand at launch. Once again, I'm scared of this thing, but did three launch, fly 2 minutes, and land. Quit after the 3rd landing, happy to have an intact, albeit battered plane (it still flies fine with a crumpled looking nose, and taped up gouges in the air duct!!)
Bottom line is I think the XF motor is a lot better than the e-flightline Himaxx 5100. I can't imagine wanting it to go any faster, but to each his own.
Can anyone give me some advice on how to land this thing, because whenever I bring it in at zero throttle, it just keeps going forever and I majorly over-shoot the touchdown. Also, anyone have experience with both the Mig and GWS warbirds who can tell me where the stall speed is on the Mig, relative to GWS i.e., how slow on approach before you stall? I'm still too nervous to experiment with this. In fact, I walk away shaking and heart pounding after it's down successfully!!!
