If this plane balances with it and no extra weight, as yours did, its a sure thing ill go with it. Ive pretty much settled on that glider drive 960 setup above. Yea, ok, that sounds like a good way to go about it. I'm sure it'll fly just fine with whatever motor you decide to use.ĭoes the glider balance on the spar now? If so, how much weight is in the nose? If not, how much weight do you need to add, and what is the total to make it balance as a pure glider (no motor)? How does that compare to the weight of the motors you are considering? There may already be lead in the nose of that OLY that you aren't aware of. LOL- I think we may all be over-thinking this a bit. It follows, I think, that if that is the case, the only extra weight I added was the lipo under the wing, which isn't much. The fact that my OLY balanced perfectly with the motor I chose serendipitously tells me that it must approximate the weight you would have added to the pure glider. If I recall correctly, the OLY needed quite a bit of weight in the nose to balance it as a pure glider. Bit heavier than i hoped, but its a proven setup (by 2400RDR) at least. The glider drive 960 comes in at 309 W on 3s (see pic below). While that might have been a bit under powered it shouldn't need more than 300W should it? My first thought, before i had bought the plane was that something like a higher kv 480 on 2s would be sufficient. Use the prop turning over very slowly to achieve air brake. My wings were prone to flutter at full power.Įasy conversion and fabulous flyer. The Oly II does not need 500 watts to climb on. Nose mounted motor was brushed with planetary gear box, until I discovered brushless. As you found, then I could run my choice of battery without balance issues. I chopped the nose off, fixed a 1/4 plywood firewall and put the battery under the wing. It worked, but I was not happy with the changed in handling caused by higher center of gravity. I was un sure of the e power at first, so I added a power pod above the wing. So- you may find the weight of such a setup beneficial. Since the battery sits exactly over the CG in the under wing compartment, the outcome is that I can use any weight battery without affecting CG, and minor adjustments to CG can be made merely by moving the battery fore or aft. The completely accidental beauty of my setup is that the weight of the motor and other stuff in the front compartment made the OLY balance perfectly on the CG with no added weight anywhere, and without a battery. Depending on the conditions, I may do as many as four or five climbs to 500' during a single flight, and after doing that come home with the battery at about storage voltage (~3.8v per cell) I never weighed it, nor have I worried too much about the motor run time because I don't do competition. That power train is actually far bigger (in terms of weight and power) than i was anticipating. What was your auw? Also how much motor time do you get with that setup? Great, thanks for the link, its a awesome build that. Just for interest sake, any idea what it is? (there's a pic of it below) Then also, on a side note the plane cam with this circuit board device strapped to the tail, the seller didn't really know what it was but suggested its a component of some kind of old style stabilization system. For a bird this size whats a good auw weight to aim for (including of course a power train)? If it is an Olympic ii the wing area is listed as 59.9 dm sq. I need some idea of how much power to aim for? The weight as is (no electronics and only servos in the spoilers) is1073g (or 2,37lbs), which does seem a bit heavy already, i am maybe wrong. Now, the thing is: I want to mount a motor and folding prop up front. The fuselage has some issues at the tail and needs some recovering. The wing, apart from being 1 piece, doesn't need much work to it. 2.55m wingspan (and as an inconvenient 1 piece). I believe its an Olympic ii (correct me if i'm wrong). I snapped up this old glider for a really good price.
