Phoenix Extra 330S 60-90 Size
One neat advantage of brass is that its thermal expansion is closer to aluminum than, for example steel.
As a result you will have less retightening to do. You might also consider some JB Weld between the brass and aluminum to control vibration/loosening- but only if it crops up.
Good Job. Hope the added nose weight is favorable... what, 1/2 oz for that coupling?
My problem is further compounded by the 91SII making the airplane tail heavy and heavy to the clkinder side. Since I dont have any lead weights left, I used some m-seal putty and a couple of m10 bolts to weigh the nose down. Since my LiFe battery is already at the tank bulkhead, no scope to move that and these are also all my lightest parts to keep the total weight down. Again, I had to put half of the weight on the opposite side to the cylinder to laterally balance, finding out how much to put to that side (between the tank and side sheeting just behind the firewall) was a real problem. Anyway, did what I could, the maiden is tomorrow. I am going to have an experienced flier both review my setup and then take her up. Have put 10% expos just to ensure that the airplane doesnt shake when I do
Wish me luck- first time with a scale-3d airplane I setup myself. Will get pics after the maiden (hopefully in one piece)- will let me test my superzoom camera

1: if your crankshaft (propellor shaft) is near centerline, you can use that as one pivot with the engine rotated to a "free", and pinch the tail fin just above the fuselage~40-60mm
for lateral balance. This will be close enough for most flying.
2: Maynardrupp had a great suggestion back about 15-25months ago..? Use a screw-eye on the belly of the plane where you want the CG and hang the whole plane upside down from that point.
This plane needed some reinforcement there in order to support the screw eye, because the balsa is so thin.
Good luck on the Maiden Flight either way...!
1) The ailerons were the other way round
2) I had positive expos on the TX whereas negative expos (on Futaba) make it easier to fly.
Both of these were cought by the experienced flier who maidened her. First we had to give a lot of right trim to make her stop rolling left. After landing we noticed that one of the elevators was not aligned. Also he commented it was a bit tail heavy. So I put the larger 3200mAh LiFe (had 1300mAh earlier) and opened and turned the clevis out to align the elevator. On the next flight after a couple of circuits he felt it was sufficiently stable and gave me the TX. I was quite surprised how easy the Extra flies as compared to the Reactor 46. In the same winds the Reactor was a handful but the Extra goes where you point. With the FS91SII I have always noticed that airplanes land very softly, just a click of power is needed. No tendencies to tipstall, atleast in sports mode. I am yet to 3D her. I was really worried that it would fly as if on a banana peel, thankfully that did not happen.
In the first flight the engine was running very rich, so nearly WOT but in the second I noticed that with the engine tuned, I was able to maintain and gain altitude even at 50% running a 14x6. Anyone with moderate low wing experience should be able to fly this easily on this setup restricted to pattern (loops, rolls, inverted). I even moved to the manual specified throws (triple rates on aileron and elevator- mid rates are as per manual) on the second flight itself
Had three flights, brought her down easy, enjoyed thoroughly after a long time. Deep sense of satisfaction that I used to feel at the end of the day when I was still flying trainers Engine still has idle issues though, will resolve them later. Happily, does not deadstick
Pics attached. Airplane is till "naked", will install the decals and trims after I clean and iron again (3rd time). You can surely see the wrinkling the sun has caused, all the seams have recessed, I even got sun burns- so hot it was today. Pictures taken with my N82 though

It is a great feeling to get a new ship flying and trimmed in.
If the OS four stroke is anything like a Saito, be patient with the idle.
It takes a few tanks of break-in (10?) before the idle is reliable.
Just fly, fly, fly for now and enjoy the heck out of this plane. Its a really fun sport flier that dabbles in 3D just fine once balanced and trimmed out.

I am planning to buy that Phoenix Extra 330S 60-90. I like to test a plane in my sim. Anybody knows a good file I can download that really fly like this plane?
I have a Real Flight 5.5. I tried on Knife Edge swap files but could not find a good one the size of this plane. I am planning to put a 75 OS on it.
Thanks,
I have no doubt it’s a great plane. However, some people like fast planes, others like slower ones or like other characteristics. When I tried the different ones on the sim, some of the 330S are heavy and slow, others are fast. Some would roll fast, others would roll slow like a trainer. So, it’s difficult for me to find out how this plane would fly with my 75. This is why I asked the question. I cannot wait to start flying it and I know I will get it for Father’s Day. I just wanted to start on the sim earlier.
Thanks for the input.
2 questions regarding landing and tail gears on the 330S
I love my 330S (O.S. 1.20 and a 16x6 prop - CRAZY pull!!)
But have 2 questions:
I am looking to replace my stock tail gear - Does anyone have a good solid recommendation for a replacement tail gear – my stock one is very old and no spring is left in the gear.
I also HATE the stock landing gear so I modified a DuBro landing gear and that works ok, but it pretty short and with the 16 inch prop, I sometimes put the prop into the ground.. well you know what happens J - But has anyone found a carbon fiber landing gear that would give me a little more height than the stock gear??
Thanks for the feedback- Great plane I am still learning how to fly it, but LOVE it!!
Bob
By the way, looking to find carbon tube 19mm to replace the heavy stock one, any ideas guys?
You know I'm still flying it like a pattern ship (lowish rates) man is it a fast one with a ys 91ac.. wondering how it will manage when I flip it to max possible rates. Landings are fast & long with this engine/prop setup
Main LG- use larger wheels. We are using 3.5" rubber wheels and a 18x6 prop

I just bought a NIB Phoenix 330s from my LHS, not knowing they were being discontinued. I guess I better take good care of it. It may become a collector's item soon!

In the meantime, I can pickup some spares while they are available. I will need a longer cowl, any thing else you suggest- wings may be?
