From the prop to the tail

[shadeyB]

Hey pilots 🎮
in most if not all circumstances I build a plane that I want then fit a motor ESC and prop etc into it 🤪
on this occasion I am looking for guidance on what to do with 850kv motor and 11x7 prop
1- what’s best size wing span to suit this combo
2 - is this combo even practical
3 - what type of plane ( always fancied a Cub) maybe a Covid19 Cub
4 - any suggestions for a build or do I go back to what I know best
as av said pilots I’ve always worked the other way 😉

what’s your thoughts

There’s a Simple Cub build string in progress:

You’ll find a lot of good feedback for Cubs on that string.

thanks , had a wee look
what’s your thoughts on the motor / prop size
Suggested wing span ?
should I just bench test it and start from there ?
ever really understood the numbers lol

I have a 60" wingspan DHC Beaver with floats running exact same size motor prop setup, its not fast but has the thrust and great climb rate for a scale plane and also has to break away from water suction on takeoff
hope this helps

‘thanks
like the sound of 60” wingspan, the beaver ? is that kinda close to looking like the FT commuter plane

I meant to post that telescoping box on the Cub Build string. Will delete it here for the sake of continuity.
I don’t have a lot of experience with the Cub design. That’s a low RPM motor & a big prop, probably a slow flyer. I’m thinking a light weight about the size of a Hobby Zone Champ RTF, 20”. I’m not really experienced enough to call it. The builders on the Cub Build string are.

Ahhh, on reading subsequent posts, @Aireal Anarchist has more reliable experience for you question. Whew.

I have a park 480 in the 850kv flavor.... What size is your motor?

The slightly higher kv 450 motor pulls my HZ 48" super cub with power left in reserve. A 480 with a smaller prop provides similar power in my PZ Sport Cub S2, 51" wingspan. My 60" Maule runs a much larger motor (15 size) 11x7.5 prop with a higher Kv (1050 iirc). But it is also a lot heavier and larger.
