If the model flies heavy I will rip all the gear out and go with some smaller bits all round and a smaller motor.. It feels fine as it is however..

What is your COG position for the 28"
Indoor maiden due this Thursday....
should be right on the wing spar. But...... go out and fly your plane flip it inverted and if all is right she will fly level if not move the battery to adjust the cg (dont trim your plane for level flight as this is a mistake on on 3d type planes.) This only helps for level flight when not inverted.

I melt out the slot with a modified 30W solder iron tip.

The spar is the mid position obtained from the online calculator .. it basically gave me 3 options which are at 10mm spacing so the least stable is another 10mm back . I will go with the spar to start..

thanks.....dave

the wing has a 9" cord so 3" back is a great place to start.

Boy is the model responsive... even dialled down low, its a bit too much for my level of competence for flying indoors... I will have to get practiced with it outside where I can have more room and height..
I am very pleased however , its very neutral and highly responsive.. but it does need constant flying, so is not so easy unless you are a 3D competent pilot..

If you have never flown 3D Dont panic You just need to learn how to use the rudder to turn. once you master tthe left hand you can fly low and slow in the place the size of a tennis court.


Watch this Video you will notice I use the rudder to turn the plane kinda whip it around the corner feel.

don't worry I am not that bad...lol... but I was trying to fly this too slowly, right on its low speed limits, indoors, and I kept over controlling.. that was my problem..
so it was a case of fly, crash, dial down, till I got it flyable...
It will be much easier outside with a bit more room to chuck it about...

my normal indoor model is an own design that's very relaxing , being aerobatic, but easy and stable to fly, its performance is very like a nutball, but its controls are elevons , rudder and throttle

I will put up a video of my slof;y when the weather improves here... too much wind at the moment

I wanted to try this plane but couldn't bear the thought of profile.

I thought super slow and aerobatic that is what I want. It is my first time with a specific 4 channel aerobat plane.

It flies pretty amazing. When I got the plans printed the wing span was 30" rather than the described 28.

The only thing I didn't like was the 6 or 7" high profile fuselage so why not make a full body. starting with the original shape and cutting over 2" out of it.

Am driving it with a 24grain 1400 kv motor and a 1000mah 3 cell battery. My standard power pack. I made the fuselage about 1.5" wide. It flew pretty weird without the flat surface of the fuselage to help guide it so I added on a few square inches of rudder. The cg is about 25-30% of the wing LE.

It will stand vertical at way less than full throttle and climb vertical pretty fast at max.

I made a video with a keyfob camera but it was poorly aimed so all I can show you are a couple of stills off the camera.


Am real impressed at the control and stability.

I have the Superslo28 and it is indeed an amazing flyer! IMO part of what makes the Slofly28, Superslo28, Yak55, and other lightwieght foam 3D planes in this category fly so amazing has a lot to do with that thicker fuselage, and the stability it creates during knife edge flight. It's acting like another wing thus creating lift, but by all means give it a go with your modification and see what it does and how you like it.

Yes thought about the tall fuselage being an aerodynamic surface after cutting it down. That is when I added the tip plates. Thanks for your thoughts.

You are 1000% correct profile planes use the fuselage like a wing in knife edge flight. The Slofly28 & the Superslo28 when built to specs is a proven frame.

Thanks for the inspiration for my plane tailflyer.

I will make a profile eventually. How does it fly in 15mph wind?

Like a ton of fun

Actually for the inexperienced that would to much wind, but if you do have the experience and the balls it's a blast

Finally the weather is good enough for outside flying...
Outside this is a different model.. previously I struggled to fly indoors, I was going too slow and too near its bottom limits..
My trims settings to fly like that were made nonsense outside.. by the time I got it re-trimmed the control surfaces were all back to level ..
Previously I also was trying to fly it with too nose heavy a COG... outside ive got it set much better although on my last flight it was still too far forward, you will see the loops got better but are still too large..

here are a couple of videos , where I am just getting used to the model..

there is lots of thrust from the 1700kv on 2s with a 9x5 prop, so hover harriers are all good .. vertical acceleration fine, knife edge is easy, but by the time I had it better sorted I realised the motor mount was a bit loose, so I stopped to fix it.. I will get some better ,closer in, video as soon as I can.. and also move the COG further back...so the elevator is more sensitive
