Went out flying today and ended having to repair the plane when I got home.
It landed ok which was a good thing since two of the three ca hinges broke in half on the rudder and the third pulled out of
the stab so I had no rudder. Good thing that they used the rods instead of the cable for the pull-pull system. Well while I was packing
up to leave I noticed the cowl seemed to be a little off and went to look at the screws holding it on and found out that the firewall had
pulled out at the top. So I came home and fixed everythng up.

Yes, I always seal the control surfaces with clear Monokote on the bottom. There is a little wing rock but not to bad. I think I set my CG at around 5" but once you fill the tank up it becomes nose heavy and requires a little up trim to keep it in level flight. You know what happens with a little up trim and trying to fly KE. You got it, tends to want to pull towards the canopy. That changes if you fly til your almost out of fuel and then the plane wants to climb all the time. I set my timer for 8 min. and that way it leaves about 1/4 of the fuel in the tank which works out ok. All in all, no big deal.

has anyone electrified this monster

Thanks for the info. I got mine in and have put it together. I still have to install the engine and radio system but the bulk's done. I am going to look into relocating the fuel tank in order to keep a more stable flight throughout. I'll let ya know what I come up with. I did my tailwheel like yours with the same equipment. Nice tip.

I don't think anyone has yet but it would be a good one to do that with.
The biggest drawback of this airplane is the lack of a normal place to put the reciever and such in the airplane.
If you electrify it than you could place it in the fuel tank area.
I have not been able to fly due to weather and other things for around a week so hopefully I will get sometime this week before
the weather turns nasty as it usually does this time of year.

Your write about no room in the fuse. I placed my receiver on it's edge and up next to the back of the fuel tank. There's really not a whole lot of choices. The only options for balance was the battery pack and it could be place under the canopy or where I have mine, sitting on top of the fuel tank.

Did not find it to comforting putting the reciever in that location.
I ended up putting the battery under the fuel tank along with a lot of foam.
The reciever ended up in the canopy area. I put foam tape around the canopy edge to keep out the fuel from getting in the area.
This worked out really well and I do like it. My only issue is were I put the switch which was a little to far back on the fuse becuase I was planning on putting
the battery back in that area but it went forward of were I planned.
Redbeard, who I purchased the plane from has one and he put the reciever in the same location and ran the antenna wire out the canopy.
I thought this was a good idea too.
He has a OS91 on it, flies great with that engine on it too.
A electrified version would be intresting to say the least as the battery packs could go were the tank is now and the esc could be placed on the lower side of the engine compartment.
I would still look at putting the reciver in the canopy area as I feel this is a good area for it.
I wonder what would be a good electric motor for this plane along with the ESC?

Got another two flights on this airplane tonight.
The fixes seem to be holding ok as I flew it pretty hard tonight.
I'm looking forward in hearing your flight report of the Skyshark that you are currently building.
I was looking at the new OMP fusion 3d profile plane tonight. It looks pretty intresting and such.
Wonder how that one would be with a Saito 100 straped to it.
Says 91 to 120 four stroke.
Hopefully I will get a few more flights on it this week but only time will tell.
John

I'm hoping to maiden my Skyshark Edge 540 this weekend depending on my work load. There is a guy at out field that has the OMP Fusion jgraham10 with a Saito 1.00. It hauls the mail pretty good. I'm going to be selling my Formula 3D after I get my Edge in the air. You know how this hobby is, fly them for a while, sell them to make room for more I flew it longer than any other plane I had so that tells you how good it is. Also it will give me room for the Seagull Laser 200 I'll be getting for one of my winter projects.

We had a demo model flown by Andy Johnson that was electrified. All the electrical setup was sorted by Overlander Batteries here in the UK. Sorry I don't have any further details.

Sym.

Sym,
Would be nice to know the specifics about the E version as I do believe this would be a great plane with a electric setup.
Zippi
I have a saito setting around since I striped my Cap maniac of all the hardware so I feel I need to get another airplane in the air.
The Formula is just not enough but I do have a Chip Hyde Cap X that I need to finish also.
That one has a YS140L going into it. Everything is there but I have to put in a new servo mount for the throttle as the saito that
was in the Cap X had the throttle linkage on the other side.
I have been looking at the skyshark edge and a few other planes to replace the BME airplane but I really have not found something
that hits me in a must have way. The formula hit me when I was looking at the one that Redbeard was putting together this summer.
John

Hi John,

If you email John at Overlander - [email protected]
Then I'm sure he would be able to help as he supplied the setup.

Sym.

i know it;s been a while since anyone has replied on here. but i started my Magic Formula 3-d today and finished about an hour ago. it took me about 12 hours to complete it. i'm using a magnum 70 4-stroke on it. i know i might have alittle more power than some because i'm running 30% nitro heli fuel and a 14x4 apc wide blade prop. i had this set-up on my Bad Boy V3 fun-fly and it about ripped the covering off a full throttle!!!! right after i got done i wanted to weigh it cause i have heard alot about it being heavy. but mine came out right at 6 lbs even!!!! all servos are in the factory places. i am using a hitec 81 on throttle, and i use li-po's for my receiver batterys with a 5.4volt regulator!!! have have high tourque ace servos on the elevator they put out about 90 ounces of tourque. hitec standards on ailrons and rudder. i really don;t like solid rods on pull-pull rudder so i uses gold-en cables for the rudder pull-pull. i'm using a true turn ultimate spinner apc cut. over all this is one killer lookin plane!!!!! and man is it big!!!!! i think i'm going to love this plane. if the 70 doesn't do as well as i think it will i got a magnum 91 4 -stroke i can use!!!


Mike

Awsome Mike! What's the advantage of the Li-po's for receiver? Fly two days in a row, lol? How did the balance come out. I was thinking some guys used larger engines?

Let us know how and when she flies!

Ernie

well you can save over an ounce or 2 in weight using li-po's and you can fly about 20 times before you need a charge!! lol i got it balanced some where between 5" and 5.5" not sure the exact but i'm between those numbers. i'm running a 1050 2 cell li-po pack. i hope to fly here this weekend if the weather here in the south holds out. past weeks have been crappy due to ice stroms and wind!!! i got my receiver behind the wing in the fuse i cut away the firt opeing in the covering and put a small floor in to strap the receiver to, and my battery is lieing between the throttle servo and the bulkhead at the back of the tank but it's not in the tank compartment. i fly and hanger 9 cap 232 120 size in imac contest and this things is as long as it!!!! it's hard to beleive how long the fuse it. i hope it does patern style manuvers good, cause i also have a pattern back ground!! i'm pretty good a 3-d so i hope it's an all around plane. i had the first magic and the magic extra and they were ok but they needed a little longer fuses to make their 3-d quailys better. think this one has that figured out!!! i will let everyone know how she flys soon!!!

mike

Way to go Mike. Let us know how she performs!

I haven't tried a Li-po for receiver yet is why I am asking. So far I think the weight savings is the best part. If yours is a 1050mah, and my standard Nimh is a 1650 AA's, I should still be able to fly longer, right?

Take care and good flying!

Ernie

I thought this thread was dead a long time ago. Nice to see people are still enjoying the plane. It was a blast for me. I had the Super Tigre G90 up front and man was it a killer. I still have it setting on my workbench but haven't flown it since I got my Skyshark Edge 540. Now that's a plane. I was trying to sell my Formula 3D with everything but the RX and battery pack but had no takers. I'll probably pull the engine off and use it on a project later on down the road. I still prefer pattern type planes more than any other. I'm just not much of a 3D flyer. Just don't have the time to practice much.

Remove

actually with my 1050 li-po i get about 10 more flight than what you will with your 1650 ni-mh packs!!! in my imac plane i was using a 1700 mah ni-mh pack and only got about 5 to maybe 6 flight before needing a charge, when i changed over to a 1550 mah 2 cell li-po i was abot to get about 15 flights before i needed a charge!!! you have to remeember a 2 cell li-po pack is 7.4 volt and 8.4 full charged!!! where a 4 cell ni-mh pack is only 5.5 full charged. that almost 3 more volts!!! even though the regulator is only giving it 5.4 it still has to work it's way down til it's close to 5.4 and plus 2 cell pack you can let get down to 5.1 volts before you need to charge it!!! thats why on li-po's you can get more flights even with less mah's, really all the mah's mean is how many amps and power it's going to give.
i an my motor today since i have never had this motor imverted, i used a tip i read on here about getting the tank cg even with the carbs spray bar and it works great, it ran like a champ inverted!!! and it has tons of power at full throttle it wanted to rip ot out of my hands holding it straight up. plus guys you have to remember i'm running 30% comp. heli fuel and 14x4w apc prop!!!!
you should try a li-po in one of you plane, just pick up a 5.4 or 5.1 volt regultor and a 2 cell 1050 or 1200 mah pack and you will see the diffrence after 10 flights and you can still keep flying!!!!

Mike you may want to read this...

Lipo's are good stuff BUT they need to be treated a bit different than any other battery type, dropping them below 3 volt's per cell is NOT good at all.

John

hey guys ive been reading along since the start of this thread and im very impressed with the plane. im getting mine today . im putting an older 60 super tigre in it. any idea of how the plane will do and any prop recommendations would be greatly appreciated, thanks.

I maidened mine and got a coupla extra trim flights and a fun flight in just the other day, weather was great with winds @ about 4-5mph. I've had this sitting around for about a year but got busy. Finally, I outfitted with an OS .91FX, Duralite 2400mah with 6volt regulator and a Hitech 5645MG on the rudder, 5625MG's on the elevator halves and HS625MG's on the ailerons, running a Futaba 9C Transmitter and an R127DF receiver, and I slapped a 14X6 Zinger on front. I setup tripple rates on my three position G switch on my 9C. For my rates, (under D/R, EXP), I set the:

Ailerons low - 30% w/-30%exp, med - 42% w/-40%exp, and high - 55% w/-60%exp.
Elevator low - 35% w/-40%exp, med - 40% w/-50%exp, and high - 80% w/-70%exp.
Rudder low - 27% w/-40%exp, med - 40% w/-60%exp, and high - 70% w/-75%exp.

These seem to be good starting settings for 3D stuff. I am still tweaking. On my middle rates I can get a pretty good knife edge but it depends what you used on your tail. I put a nice tail wheel setup so had to use more nose weight to balance. Ailerons seem perfect for my feel although I'll probably kick up the expo a little as it's a little sensitive to me but still manageable. When going to high rates it will go right into a Wall and Waterfalls are great. Hovers are manageable with these settings but still take some work. I have to do some more tweaking to get the hovers just right. On low rates this plane will float in for a landing. You can amaze people with your "touch and goes" instead of "bounce and goes" like some people do. It's a very smooth and agile plane and I can see I'm going to enjoy it for a while. It flys like a smaller version of my Mayhem, which can make a medium pilot look good and a good pilot look great. Same thing with this plane. It'll make you a better pilot by letting you relax and try some things you haven't tried before. Good luck and hope this helps.

Hello, is anybody still flying this model in 2007? i just purchased this arf and its just sitting there waiting to be built. anybody want to build it for me and make some cash?

I've always liked the looks of that plane. Check with any clubs in your area.

Best of luck,

Ernie

My 15 year old son just moved up to sport aerobatics and he's flying this plane. He flew it for the first time easter sunday and loves it. He can't wait to get back out there.

What size engine did your son use?

Thanks,

Ernie
