Flew my profile piper, 330, and Radion Pro.

Great day at the field.wmv (8 min 42 sec)

This is a very gentle plane, lots of fun and very easy to fly. Lots of room for modifications. cost one dollar

What a great day at the flying field

This is one fantastic plane

This plane is fantastic, If ya dont have one build one. 450 size motor 850 KV 10x7 Slowfly prop. 1300 mha battery (3 cell) WHAT A BLAST

Motor and esc with hardware and she flies

This will be my FY-22

This is made from one sheet of Dollar tree foam Belive it or not

My new favorite and her Maiden

Maiden of the Radian Pro (6 min 14 sec)

My first attempt at making a 330 did not go great. It flew just not high alpha and was floppy. So instead of a $5.00 sheet of EPO I used a $1.00 sheet from Dollar Tree. This plane is a Rockstar.

This is my 5th scratch build, she is a smooth flier and will do 3D, This was her maiden and I have only been flying for 7 months, so a little more practice. She gets color in the morning.

Radian Pro first Air Video (6 min 45 sec)

150 foot ribbon pulled this morning at Legacy Park. Thanks to Bowsonn and BoomSplat. This is hard on the ESC and motor and battrey. It was 16 degrees with wind chill and the wind was blowing 10 MPH steady. The plane becomes tail heavy Duh so be ready for it. My plane has 26 oz of thrust and I think I can pull more.....maybe a addittional 50 feet. and with some practice tie it in a knot while flying. This Vid is EPIC.

Just a great day with a great plane

Wings Over Legacy (7 min 5 sec)

Lots of fun and you get to see how tough the Reaper is BoomSplat brings her in veritical from 200 feet and smacks her on the nose,Repairs took less than thirty minutes.

This is a Extra 330, my first attempt at building a 3D plane. I will be using a 2812 motor from HK and a 1300 mHa battery (Nano Tech). The ESC is a 25-30 Amp Plush with a 7x6 prop. The Rx is a orange Spectrum from HK. Might try a larger prop don't understand the whole prop thing yet. The CG will be at 2.35 inches back from the LE for now, will most likely set her a little tail heavy will see. She is made from 9 mm EPP on the fuselage and 6 mm EPP for the wings and horizontal stabilizer. WS is 36 inches and build weight with no hardware is 3 oz her up weight will be 13 oz.

More of what I know, to help others

--------------------------------------------------------------------------------

I have read a few post her that lead me to believe that some of us here are not sure what a CG is or how to find it. Some here write as if the CG is a movable point on the plane that can be solved with trim. I hope this bit of info clears it up. Now I am no pro but have now built 3 scratch aircraft one with no plans and of my design.

Correctly balancing rc airplanes is so important for safe flying, because any deviation from the model's Centre of Gravity (CG) can potentially result in the model being quite uncontrollable.

Every rc airplane (and all other aircraft) has a specific CG position, it's the mean point where all gravitational forces act upon the plane and hence the point where the model balances fore-aft correctly. You can liken a plane's Centre of Gravity to the fulcrum of a see-saw, for example. The CG point is determined during the design stage of the airplane or aircraft and is typically shown on a plan as a disc split in to four quadrants,

If you've built from a kit & plan the CG should be clearly marked on the plan but if you've bought an ARF or RTF plane then the instruction manual will likely give the CG position in terms of distance back from either the leading edge of the wing or from the nose.
Incidentally some model aircraft manufacturers specify a range that the Centre of Gravity can fall in to, rather than a single...Continue Reading
