I did this conversion several years ago, with a 160 size motor on 6s. Used a 22 x 8 prop. I am away from my computer for about a week, so don't have the pics available to post, but I may have done a conversion thread here on RCG. You can try a search to find it, if not, when I get home, I will post the pics.

My Flair DR1 uses a G160 turning a 20/8 prop. 245kv

10 cell lipos ( 2 x 5000 mah , 5 cells ) , 90amp HV Esc.

I also have an AXI 5330 /18 motor which is pretty similar in size but way more grunt!

Adamtc, Isn't the Flair a larger model? 70+" vs 63" on the Ziroli.

Trying to cut down on the number of cells tlh101 used 1-6s 5000mah @20c.

quick look at Hobbyking reveals several motors that should be capable of flying theDr-1 . There's a G160-245kv, a G160 - 290kv, a G110 -295kv, and SK3 6364-245kv ,and a SK3 6364- 213kv.
The lower kv motors would use 22" props while the higher kv units would be likely limited to 20" or so on 6S.
If your using wooden props, either gas or electric will work in these larger sizes, the lectric advantage is slightly lighter, a little higher rpm, with maybe a slightly lower amp draw.
At 13lbs AUW, this plane should fly quite scale with 1500watts/70a on 6s. fwiw Doug B

Doug,
Well getting more confused now. Have aE Flight Power 160 on the shelf,the specs read 245KV and the writeup says 9-10 cells with a 20x10 max prop,would love to use this motor on a 6s setup so I wouldn't need a CC HV esc,could use a Talon 90 with built in bec . Would use a 22-8 wood gasser prop. Is E Flight covering their bets with such a conservative spec sheet?

9-10 cells on the 160 would likely produce something in the neighborhood of 2500watts. I've seen several people use them beyond that. Your looking for 1500 on 6s, it will take a large prop with good pitch to get there ,, but at much lower rpms. Assume the motor is 80% efficient under load, so a 245kv motor will be turning approx. 196rpm for each volt. At 10s your motor will turn 7252 at 37.5volts also under load. The 6s system will turn the prop only 4214rpm at 21.5volts loaded. You use a prop that takes the motor to 1500watts. or 69A, all well within safe limits for an Eflite motor. Doug B

Bob,

Yes the Flair is 1/4 scale so much larger.

1500w is the figure you get from a 110 sized motor on 8 cells. I had the eflite 110 on a 16/10 and that was very powerful and efficient. I wouldnt want to run a g160 on 6 cells. It will look and sound very odd running at 4200 rpm. For the DR1, you want the ability to get air over the controls during landing and takeoff quickly and the 110 motor seems a better option to me.
