Help! big stuff small plane

[xavche]

does anyone know if you can put a power pack b with a 1300 mah 3s batt in a mighty mini plane?

(i whould like to make a mighty mini mustang but i do not have a power pack f)

It would probably fly, but it would be quite heavy. I think that means it will have to be flown fast to prevent stalls and you’ll need a long takeoff.

you can scale the plans up using adobe Acrobat.

i whould like to keep it at a mighty mini size. but thanks anyway

The first FT plane I made was a mini Old Speedster. I put in a power pack B because it was sent to me instead of the A pack. It used a 9X4.7 prop. There was way too much torque on a prop of that size for the mini. The flight lasted for about three seconds before it rolled uncontrollably into the turf and self destructed.

Mini Mustang might be OK but beware of torque roll with that small wing span.

I agree with Gazoo.
Even if you throttle back so that the big motor is producing the same thrust as the smaller motor would the bigger prop will still need more torque. Add to that the extra weight will mean its minimum speed for adequate control will be that much faster which means a bit more thrust & torque. You can see the problems of the first few seconds of flight with such a layout.

It may be possible to get away with reduced power and a strong launch but those first few seconds will not be easy.

i am making on right now i will see how it goes (i want to make a forum thread from the project)

 

[xavche]

beacause of the nose weight whould it be a good idea to put the servos in the tail boom?

Yes i think it would be

ok

i don't really want to fly with a foot and a half of snow on the ground so i think i will continue this
project in the spring

Make some little floats for the snow and send it! I think you need more power for taking off in snow so you just have a reasonable use case for being over powered.

floats on a mustang!?! are you all right?
just kidding

Well now you’re pretty much obliged to do it.

 

[xavche]

WHAT!!! were did you get that?!

 

[xavche]

i think i will make a bush plane instead

 

[xavche]

with skis

I put a B motor and 850 mah in a Tiny Trainer, faster, more fun, flew with authority!

 

[xavche]

do you think it would work with a 1300mah my stuff is in an old fogey on skis
(see my other post)

 

[LundiThembi]

I don't have experience with that plane. Check your CG and go from there
