I have a chance to pick up a reciever-ready world models 80" extra in the wagstaff color scheme for what I think is a pretty good deal.
It's ready to fly, with servos, battery, OS 1.60 with pitts muffler, ready to go and I they're asking $400. 6 to 8 flights on it. Seller claims like new condition except for a small repaired poke hole in the covering.... Going to look at it in 2 days but the wheels are spinning already......

I know that a lot of folks seem to say to go with at least Moki 2.10 and preferrably a 50-55CC gasser. I had an 78" H9 Edge 540 with the 1.60 in it and was very happy with it's performance, so I'm guessing I will get about the same perfoemance from this plane?

Can't find any 'official' reviews of this plane, few to no useful videos, and only about 10 user reviews here on RCU, though the reviews here are all very positive.

Comments? Anyone out there that owns this plane comment on it? Any links to professional reviews?


Thanks!

I have two of the extra 300s. I bought one and liked it so much I decided to buy another one. The first one is powered gy a Magnum 180 4 stroke. It doesn't have unlimited power but it's fun to fly. I plan installing a 50 cc gas engine soon. One of my friends has one with a DLE 55 and it has plenty of power.

I had one with a Moki 2.10 in it. I was very happy with the plane. Flew nice and did everything I wanted it to. I also had a Sig Extra 300 with the OS 1.60FX that weighed 14lbs and it did a great job with it. I couldn't tell you if it would hover it if you're into that, but it should be able to do about everything else you'd want. I sold both planes, but was very happy with the WM Patty. That sounds like a great deal.

How do you think

Oops...


how do you think it would fly with a Super Tigre 3250 on gas? Asking because I just retired my Funtana .90 that I had the 3250 on, and it's looking for a new home...... I have a funtana 125 that I was about to put the 3250 on, but I am thinking it might be better to put the 3250 on the Extra and move the 1.60 to the Funtana 125. The 3250 was spinning an 18X8 on the ground at 8800 without messing with tuning (never tried to peak it out, just flew it how I got it), and yanked the Funtana 90 up like a missle, even at about 11-12 pounds. The 3250 is 32cc, or 2.0ci.

Thoughts????

My Moki 2.10 had a 20x10 turning I believe 7400rpm if I remember right. 8800 on an 18x8 pretty good power. I cant imagine that wouldn't fly a 15 or so pound plane. I dont think I was quite getting 8800 with a Xoar 18x8 on my OS 1.60FX if I remember right. I'd sure give it a try. Just my thoughts for what its worth.

Thanks! As long as the plane is in it's described condition when I go look at it tomorrow, I think I'll have a new addition to the hangar.....

Well to close the thread I did get the plane. It was in great shape, like new. Seems to be a nicely built airplane. I'm going to see how it flies with the 1.60 on it and go from there.


Thanks.

Flew the Extra for the first time this past Sunday 3/7/10.

I ended up swapping out the glow OS 160 for the gas ST 3250. Also went with a much smaller fuel tank (16oz) and moved the tank rearward to just above the wing tube.

The manual I found online listed the CG as 130mm. Even with the dual 5-cell 1600mah batteries strapped to the engine mount it was just a hair tail heavy (probably about 135-140mm), but I decided to go with it.

I also had to swap out the 9303 that was on the rudder, it oscilatted pretty badly when returning to center. Used a Hitec 645MG I had lying around.

I put two flights on the plane. First flight was just about a 5 minute flight to get it up and trimmed. I required a lot of down elevator trim, the plane wanted to climb a lot. Once trimmed, it held inverted flight well so I think the CG is pretty good where it is. More on the excessive trim in a minute.

Plane flies great with the ST3250 gasser. Plenty of power. I actually forgot to try to put it in a hover, was too busy just flying around, but massive loops and looooong uplines were no problem. Plane cruises around at about 33 to 40% throttle nicely. Full throttle is pretty fast with the 18X8.

Second flight was a bit longer at about 9 minutes. Again, no suprises, flies very well.

Plane does not want to land, just keeps floating. I almost had an incident when landing after the first flight, I killed the engine intentionally on final just before I flared, however it was gusty and the plane balooned back up at just above stall speed. I shoved the nose down and was able to save it, just came down a little rough but no damage whatsoever.

Second flight I practiced landings, did about 15 or 20 touch and go's and aborted landings.

When I got home I put my incidence meter on the wings and tail. The wings were both even with each other, as were the tail feathers, however the wings were set 2 full degrees off from the tail. This explained the excessive down trim I needed in flight.

I also found that the firewall actually broke loose from it's tri stock and was simply held in place by the tabs on the side of the engine box. Major disaster averted here somehow. I am rebuilding it, looks like whoever built it originally only used 2 pieces of tri stock and not much epoxy. The OS160 was also soft mounted, as opposed to the 3250 that's in there now hard mounted on aluminum beams.

Overall I was very pleased with the plane, and once I get the wings set correctly (simple mod, they just use locating dowels) and the firewall rebuilt I think this will be a very nice plane for a long time to come, unless of course I end up doing something stupid with it.

Great to hear. Thanks for the update.
