RE: Why you love the OMP Fusion?
HI Guys,
I am running a YS 110 in my fusion and it acts like it is going to take the front of the plane off.
At low throttle the head on the engine is moving about 3/4 of an inch and I only have about 20 flights
on it. What is it going to be like after several hundred? Any ideas about stiffening up the front end?
Thanks Mike,

RE: Why you love the OMP Fusion?
We have 2 Fusions in my club that have filled the noses with Gorilla glue so they will better absorb vibrations from the Saito 125s. We drilled 2 holes in the font ends (top engine beam area, bottom area). Mix about 4 oz glue with a tiny bit of water and use an empty epoxy squeeze bottle to ration the glue into the two areas through the holes.
Plug any open areas up to the wing tube area with masking tape to contain the glue as it expands. It should expand to just beyond the front of the wing.
After squirting in the glue, masking tape shut the holes and lay the plane on its nose for 8 hours so it will fill up the nose and gravity will help it get to all the nooks and crannies.
You'll add some weight with this method, but it's a lot easier than the alternative of opening up the inside.
Another area to consider is the alternate battery area on the lower left front side. You may want to put a lite ply cover over this area after removing covering so you can glue the perimeter well.

Bingo, give that man a cigar! Yep, gorilla glue is the best stuff and works great to fill areas without tearing the plane apart. Great suggestions Wind Junkie! I've got a YS 110 on mine and had to redo the nose after about two years of hard flying.

RE: Why you love the OMP Fusion?
I noticed on mine the ply engine mounts were seperated slightly by the I-beams from the foam. From the manual pictures it looks like the sheeting were supposed to come to a stop above the I-beams but then nothing would lign up at all. Might need to get some filler in to fill the gaps slightly. I'll check it out before I cap it. The foam cores didn't match the sheeting/engine mount very well so I did the best I could to compromise here and there...I'm sure it's all good and all no problems. Just gotta get this slight warp out or minimized then I'm trucking on.

RE: Why you love the OMP Fusion?
Little hard to describe the little booboo yes, not sure if pictures would show it clearly either but yeh reason I aint complaining is cause I'm not too sure it's not something I mucked up either? When I ligned the in place pre build hardwood engine mounting rails up with the ply sheeting doublers's cut out the fus sheeting was actually overlapping the bottom I-beam a little more than halfway. Later judging from the pictures in the manual the sheeting looks like it comes to a stop butting into the bottom I-beam? But this wouldn't work as the I-beam is not wide enough anyways. Either way, I aligned the engine mounting area properly and tried my best to get the wing tube and alignment holes aligned vertically as well as the rear of the sheetings so the stab and such would be close enough then just glued it all together. My I-beam was a teensy bit wider than the foam core but barely a fart so it lifts the front ply doubler slightly from the foam in the motor mounting area...this is really barely noticeable but maybe a good idea to pour some thinned wood glue in there or something just to beef it up for the shakey 1.25? The foam core is slightly bigger than the sheeting around the rear of the cockpit and top of the fuselage also, but this I'll just trim away, not much (Maybe 2mm). At the back of the fus though the sheeting is about 15mm too long, easy to trim also.
I'll get some pictures asap.

RE: Why you love the OMP Fusion?
The important thing is to make sure both sides are aligned with each other and it sounds like you paid good attention to that. Using the wing alignment holes as guides is a good way to do this. Excess foam around the perimeter is easily sanded off prior to capping.

RE: Why you love the OMP Fusion?
Yeap thing should be aligned well side to side so I think the important bits are taken care of. I got some other priorities I'm taking care of quickly then I'll get some pictures of the progress again when I get stuck into it again.

RE: Why you love the OMP Fusion?
Well I got the fus sorted I reckon. Basically everything's done cept cutting off the excess wingtube sleeve and sanding which I will get around to once everything is framed up. It turned out well, straight as I'll ever get it.

RE: Why you love the OMP Fusion?
Hi everyone!
Well frame up is very nearly completed. Just gotta fix on the fin and finish that up. Then it's time to read through the instructions again to make sure I didn't miss anything and well...cover.
Current bones weight as in the picture is 1200gram. Little heavier than I hoped but ok I'm not down just yet, gonna battle on and hope for the best.

RE: Why you love the OMP Fusion?
Maybe fluffy was sitting on the scale along with the plane. Honestly 1200 grams is only 2.64 lbs. Target weight rtf should be 7.25 lbs or for you 3290 grams or so.

RE: Why you love the OMP Fusion?
Hahahah...all part of his evil plot to get back at me for putting a plane down between him and his ball I suppose?
1,2kg is definitely not terrible but I'll admit I built the fuselage a little heavy for my tastes. I'm known to build things heavy but I think I messed this one up badly. At the moment it still looks like I can make the 3,3kg mark dry easy but I was hoping to keep it below 3kg dry so it would shine with the 1.25 on the nose. If I break 3.5kg dry I'm buggered with the Saito and will end up flying pattern for the most part with this bird, still going to try to avoid that. Looks like I'll just have to go easy on the glue from here on. Not backing down on my mission impossible colour scheme though, already forked out a $100 too much on covering for that now.

RE: Why you love the OMP Fusion?
Honestly we've flown a lot of Fusions and done a bunch of testing and the Fusions fly better at about 7.5 lbs then they do at 7 lbs. Yes.....this is true....they fly BETTER at a heavier weight......but not too heavy of course. This was not surprising as the Fusion was the first plane I designed in which I was targeting a specific wing loading rather than just buiding a plane as light as it could be. If all you want to do is 3D then lighter is better...perhaps.....but for "artistic" or "freestyle" flying the proper weight for a given plane design allows much more precise flying and allows the a/c to carry through it's manuevers. John Drake's Fusion weighs 7 3/4 lbs and flys pattern better than mine which weighs about 7 1/4 lbs.

RE: Why you love the OMP Fusion?
Yes we have seen this very distinctly on our competition gliders also, they were designed to be silly light but get it too light and guess what the plane starts to really lack characteristics in some areas. Sure we've managed to get them too light and they do float and get sucked up in light lift much better but as soon as you start talking covering distance to get out of sink and navigating wind you run into serious problems. I've also seen these problems with competition fun-flies I used to play with a few years back. Get em too light and you're outta luck on 10 of the 20 rounds but shining in the others, go the other way and add a few grams and you got an excellent plane all round. I can see this happening on the Fusion no doubt.
My biggest problem however is simply the power of the Saito 1.25 at the altitude I fly, my old Yak this motor used to fly in at 3,6kg dry didn't have any pull out of a hover. In fact it was a near impossible task to pull a half decent rolling loop with it. However I'm confident that with just a lbs off the Yak's weight the motor will be excellent. I mean 200grams on a .46 sized profile with a OS .46 makes a helluva difference in punch out performance here by me, day night actually. I do have the OS 1.20 AX in my girlfriend's trainer if the Saito sucks in this plane but still I'd like the four stroke over the AX in this thing. The 1.20's throttle response is nowhere near as impressive.

We have 2 Fusions in my club that have filled the noses with Gorilla glue so they will better absorb vibrations from the Saito 125s. We drilled 2 holes in the font ends (top engine beam area, bottom area). Mix about 4 oz glue with a tiny bit of water and use an empty epoxy squeeze bottle to ration the glue into the two areas through the holes.
Plug any open areas up to the wing tube area with masking tape to contain the glue as it expands. It should expand to just beyond the front of the wing.
After squirting in the glue, masking tape shut the holes and lay the plane on its nose for 8 hours so it will fill up the nose and gravity will help it get to all the nooks and crannies.
You'll add some weight with this method, but it's a lot easier than the alternative of opening up the inside.
Another area to consider is the alternate battery area on the lower left front side. You may want to put a lite ply cover over this area after removing covering so you can glue the perimeter well.

I assume you are talking about beefing up an already built plane. If its a new build how would I go about reinforcing the fuse?

RE: Why you love the OMP Fusion?
I can't be sure but I'll bet Windjunkie is reffering to the ARF version Fusion? I think this one might be built up rather than a foam core fuselage?

RE: Why you love the OMP Fusion?
Hi Mike,
Great flying plane, but I don't know how you got 2 years out it with a Y.S. 110. I have just about 30 flights on mine and the engine
is starting to twist the front of the plane off. I am going to try filling it with foam in the front and maybe remove the covering in the wing area and try epoxying the wing solid to the fuse to see if it will absorb some of the vibration at idle.

RE: Why you love the OMP Fusion?
It was two years before the engine came off the front. Mostly from some oil damage as I was lax in keeping the area fuel proofed. Use gorilla glue or similar to fill the area and make sure you fuel proof very well. Also make sure you balance your props to minimize vibrations.

Since I have the kit version, I won't have to worry about reinforcing the nose then, is that correct?

RE: Why you love the OMP Fusion?
My fuse is also slightly warped to the right, but I figure it might have the right amount of right thrust built into the fuse! Its really not noticed unless you hold it up to your face & sight it down the length.

RE: Why you love the OMP Fusion?
Hah then it sounds pretty straight!
I've been on a nice holiday the last month odd (Read simply sleeping too much all the time) but still going on the covering thing. Plane has been all white for a few weeks now and I'm adding trim when I feel like it. Think I kinda bit off a bit more than I can chew with the colour scheme but we'll see.
