Help! Warbird scale down?

[BradDH]

Hey everybody, I just made a cub, and it flies really well, but I was wondering if it would be possible to somewhat scale down the c pack warbirds and use them on a b power pack?

Heres a quick pic of the cub

The Simple size warbirds will fly fine on the 2212 1000kv motor. My scout is made of heavy UK board and it’s running that motor.

So you think I could manage a mustang or spitfire? My motor is 2212, 2200 KV

It's possible to scale down, but beware, when you scale, the aerodynamics also change. That is the wing loading will change substantially. For most of my FT planes a wing loading of 12-15 oz per square foot works well. But when you go to the size of an indoor plane the wing loading is 1-2 oz per sqft, a 10 fold change.

The spitfire (first version, not the new master series version) is very light and would fly just fine on that motor at the normal scale.

Ok cool! I'll give it a shot after I get some more foam.

Are you sure your motor is 2212 kv2200? if so, I would recommend building a pusher jet (assuming running 3s with 6” prop) instead of a warbird. unless you are using 2s battery with an 8” prop.

 

[BradDH]

Yes I am running the 2212 kv2200, 3s with 6x4 prop.

 

[TDL]

I am afraid that 6x4 will be too small for a 40” wingspan, low wing plane, especially for hand launching. F-22 will be a prefect match for that motor!

 

[FDS]

If it’s a high KV then the above may be true.
Motors are not expensive, I would buy another for the spit.

 

[BradDH]

Do you think this will work as a motor for all the regular sized planes?

These are just a little more and are the ones that came in the C pack before they switched to their radials:
