Currently upgrading a sundowner I got a while back, but only flew once because I got out of the hobby. It had a jeti 77 with a Axi 4120/14 on 4s. It was cool, but a turd! Anyways i'm putting this motor on it

http://www.hobbyking.com/hobbyking/s...ch=ntm%2050-50

with a Castle Edge 100 ESC and 6s 5000. I've got a 13/10, 12/12, 11/10, and another 12/12 to cut down to a 11/12. Anybody have a good guess of how fast it will be? Shooting for the limit of 2000 watts. Going to try the 12/12 first once its all together. Just to clarify my findings I should run a regular APC prop not an E due to high rpm correct?

I have the same kv on my motor on 6S. With the APC 12x12pattern you can expect ~120+mph flat and level.
Your biggest problem will be to get your spinner vibration free!
I had prop flutter problems with the 12x12E APC.

Cool that's what I was shooting for. Just need to throw the new servos in it. I don't trust the standards that are in it now. I picked up a Great Planes spinner for it and I forgot what crap they are! Wobbles all over the place! Guess I should have just spent the $$ and got a Tru Turn.

I have a new still in box Sundowner 50 that I'm planning to build, I was wondering if there is any new recommended ~120 mph setups?

No more sundowners flying
I read a lot in this thread and saw a lot of great recommendations but I just wanted to know if there's any new fast and efficient motors that you experts can recommend
Thanks

When your tired of replacing NTM motors, buy a Scorpion 4020-12 or its new brother the SII 4020-540. I ran the former on 6S at 77A for countless flights, motor always ran cool and fast on a 12 x 12 Apc E prop. I use the aluminum spinners from Hobby King, excellent value for the $$. Other venders cal them Pro Spin spinners. fwiw Doug B

What kind of speeds did you get with that motor on 6s ?

I concur on the Scorpion 4020. I use the 4020-10 on 6s, and it's great. The -12 on 8s is a screamer as well.

I've been running Scorpion HK4035-560kv Xoar PJM-E 12 x 12 prop 5400mAh lipo best combo for this plane, XOAR prop draws 10 amps less than the APC-E 12 x 12
Love My Sundowner, what a shame that H9 stopped producing them

I have run 8s and 10s setups but have gone back to 6s the plane flies better and not allot more performance to be honest
this would be a nice 8s motor on special at the moment 1/2 price
