big sig kavalier

[paulatgis]

this here is my big sig kavalier. wingspan 82 inches. making it light so I can use a 40 size motor and 4 cell battery. have 5 cell batteries too just in case. im actually going to try to use an sk 4240 turnigy motor, being the weight miser that I am. would be super light then. 5 lbs easy if not 4. have to see if a 13x8 prop will work, if not ill swap motors and use 15x8 prop. i like sigs red white and blue covering scheme, so I tried to copy that.

i have a smaller kavalier at 36 inch wing span that flies very nice. so what the heck. scale it up for big bird club fly ins.

im hoping it will go vertical reasonalby well and then spiral straight down. thats pretty much the only trick I know.

color scheme and sig picture. definitely a favorite looking plane. looks real fun to fly.

finally finished my big sig kavalier. came to 6 lbs with 5 cell 3000k and 4248 sk motor with 16 x 10 prop. Now just need to see if it fits in my Jeep.

Looks great - I have many fond memories of the Kavalier back in the late 70's.

What is the final weight?

She looks great, paulatgis! Great job on the covering. I'm looking forward to reading about the maiden flight!

i switched out the motor from 4250 (15x8 prop) to 4258 (16x8 prop) to keep my 60 amp esc cool. Feels like it has plenty of thrust, with such a big wing and total weight at 6lbs I should be fine. charging batteries now, might get to fly tomorrow.

nice day at the field. the plane flew without a hitch. flies just like the smaller kavs - lots slower with the less wing loading. very docile. slow rolls. fun touch and goes.

Awesome - I love it when a plan comes together. Great job....

Great looking plane, very well done.

ive been flying this lately. im going to see how it handles more power and speed. check for flutter and vibrations before i put i a bigger motor. i need to get more speed to cure the slow rolls.
