I have one of these. It's the 940kv version.It says it will fly a plane that weighs up to 20oz. I could have sworn that I've heard of guys with this same motor flying planes up to 26oz. Is this too much for this motor or will it handle it? I was wondering if it would be strong enough to fly a plane like the Mini Funtana?

Is that the 740Kv or the 920Kv? If the latter, the max amps are 10A cont/13A burst - say a bit over 100W on 3s - that'll fly a 16oz 3-D machine (at the "rule-of-thumb" 100W/lb) but not much more. What's the AUW of a Mini Funtana?

Of course, it would fly a 40oz floater or trainer at 40W/lb - but clearly that's not what you want for 3-D.

Cheers, Phil

I have the Park 400 920Kv outrunner. According to Horizon Hobby, the RTF weight of the Mini Funtana is 20-25oz. I don't care about flying 3-D. I just want to basically fly it like a pattern plane. You know, like loops from level flight and rolls. What do you think? You seem to have a pretty good grasp of this!! Steve

I have a Mini Funtana, and I have a Park 400 920 but not as a combination...

IMO, the Park 400 outrunner will fly the MF and probably do it in the manner in which you describe.

My MF has an AXi 2808/24 that has substantially more power (about 250 watts) and I'd think the Park 400 920 should be good for about 150 W. max. maybe?

I have yet to use my park 400/920, but I've asked around, and they recommend a 10X4.7SF as about the max. prop for that type of airplane. (that's where I got my watt figure from)

If you figure a pound and a half airplane, with 150 watts, that's 100 W. per lb. which is pretty good, and should give you the sort of performance you want.

If you're just cruisin' around, that shouldn't push the motor too hard, and you'll have some reserve for "emergencies" :)
