Default Step 1.5 in my first scratch built foamie

I guess I'm posting this as motivation to follow through on this. The attached pic is of the templates ready to be cut as guides for hot wire cutting foam for my first scratch built RC. It'll be a low-wing, 4 channel micro-flier. No idea how it will turn out, but I'm having fun with it!

Looking Great make the main wing just a little wider for more surface area to help carry the power systems weight, just my 2 cents worth, Take care, Chellie

Hi, maybe some of the threads below might give you some building ideas for your scratch build Plane, hope that helps, Chellie

Thanks for your input Chellie! I took a SWAG at the wing loading and think it will come in somewhere around 5.3 oz/sq. ft. What is a decent wing loading for a micro-flier like this little guy? I am hoping it will be similar in performance to the Parkzone Ultra micros. Based on the info I could find for Parkzone, the UM F4U has a wing loading of 4.3 oz/sq. ft.

I'm planning on using a brushless motor (haven't picked one, yet) and 1s battery. I'd like the plane to have a good bit of zip, yet be able to fly slow enough to be flown in a gymnasium. I want my cake and eat it, too, dammit!

All of my landings are three point landings if you count the spinner, too

Hi If you can get the wing loading closer to 4.3 oz/sq.ft, it will fly better for you indoors, use a 2 cell lipo for better performance.here is some info for you, Take care, Chellie

Ok. I'll bump up the wing area to hit 4.3 oz/sq ft. If I go with the motor and 2 cell Lipo used in the post, I'll think I will have the handling characteristics I'm looking for, provided the weight works out as expected.
Thanks, Chellie!
