60" Practice Plane

I have a couple 1.5m pattern plane for practicing precision pattern sequences and a 48" 3D plane (Extreme Flight Extra 300) for sport flying and just hucking around. From what I understand IMAC...

How to spin

I was look at the IMAC Basic sequence. I thought for variety, I might start practice that sequence in addition to Sportsman pattern. All the moves seem about the same level of difficultly except...

Just so I understand the differential thing. If flying in roll in a vertical downline I get wobble/corkscrew, I want to put in less throw on the down aileron and more on the up?

How about just one horizontal roll?

I read the three-roll thread and that started me thinking about me trying to keep my one horizontal roll in line when flying Sportsman.

My Monolog-70 tracks straight in rolls with little if any...

I did some more calculations and computed a theoretical value based on the prop area * S^2 * pitch. That's the second to lastcolumn (the formatting is tad messed up). Also calculated the pitch...

Just realized, I need to work on the calculations more. The d^4*p formula compares load assuming the same RPM, but the RPM won't be the same from 5S to 6S with the same motor.

Are you referring to the motor in the Splendor? The replacement prop is listed as an APC 14x7E, not a 15x8. A 16x10 sounds like way too much of an increase.

From what I understand prop load is...

I just noticed the GP120 in the Tower catalog also. It's seem to me a 5S 5000mAH sounds small for a 120 sized plane. I fly my 70 sized plane with a 5S 5000mah. I would think 120 planes fly on 8S...

How does it fly on 5S? Did you have to use a higher pitch or bigger prop?

I have some 5S 5000mAH packs for my other plane. I think they are going a fair amount bigger than 6S 3300mAH, maybe...

Ordered a Practice Plane

I wanted a smaller practice plane (since I lost my 46" plane this spring) I can just throw in the car, fly a few packs at the local field after work and then come home.

I heard the HK Arcus...

No idea how similar the plane is but I fly my Monolog 70 with an A50-12S, 5s5000mAH, and an APC 15x10. I get about 7.5 minutes with and put about 3000-3500mAH back in after a flight only draining...

All that stuff about into the wind makes perfect sense.

Now an observation about my flying. I believe most of the time I stall turn to the left regardless of wind. So on my turnarounds, it's...

Question Question about Stall Turn, Quarter Roll Up and Down

Even though I only fly Sportsman (and can barely fly it at that), I like to when I'm flying just for run try the intermediate maneuver Stall Turn, Quarter Roll Up and Down.

I have one question...

Thanks for all the info. I noticed by canopy base is a straight line and there's a trim line parallel to that the entire length of the fuse. I also noticed that the flat surface of the bottom of...

I didn't measure the stab as I didn't have time. Also, the fuse as a flat bottom, make it easy to stabilize for measurement. But I assumed that the bottom of the fuse is parallel with the zero...

Plane Measurements (neg Gs / down elevator loop part trois)

One of the suggestions in the other threads is to check set up. Did some measurements on my plane. This was simply with a metric ruler and a CG stand as I don't have an incidence meter (but I can...

What would I measure? The only static test I know of is the position of the CG with respect to the recommended CG.

I know some of the basic flying tests like fly a 45-degree up line, roll over...

I've done a bit of trimming from the tutorials I've found but will try working on it some more. The plane doesn't seem unstable so I figure I could nudge the battery back a 1cm per flight and see...

Nudge of down elevator at the top of the loop

If I interpret all the responses in the Negative Gs at the top of the loop thread, I should fly with enough airspeed and power that the plane always pulls positive Gs for any reasonably-sized loop.

Niether, get an Aeroworks Stingray or Eflight Leader 480. GWS kits are so dated and crappy. For an extra $50 you can get a wonderful wood plane that won't be a pain to build, will set up much...
