RE: Fliton Extra 330 Freestyle Who's Got One?
[quote]ORIGINAL: badfish key is finding a happy spot. I would definately put up with a little shaking over having a dead stick. another thing I do is listen for the rpm drop when removing the glow stick. the richer it is the more your rpms will drop. steve [/quote] Yep, that is why I have it set so lean on the low end. Set up inverted and set lean, there is still a noticeable drop in RPM when glow is removed. As long as I don’t go full open/close/open/close/open real fast (as in fast waterfall—this FL is capable of wicked fast WF’s[8D]) then I don’t have a problem.

I have mine mounted inverted and have the low end as lean as possible. The down side to this is that on waterfalls I have had the motor quit with rapid increase & decrease in throttle.

My SA100/FL330 does not vibrate that bad. It does idle down nicely. I run 5-15%nitro. I am comparing it to YS110 on 68 yak. I like the smoothness of the two strokes (OS32,55,91,120,160).

RE: Making turns during rolling harrier
Congrats!! I think I know exactly what you mean. One thing I have done to improve my flying is to slow down the sim very slow to nail down the timing. Eventually I can turn the speed up very fast and bias the model so that it is harder to fly than at the field. I think flying the sim some at a very challenging settings helps increase reaction time (like lifting weights).

RE: Making turns during rolling harrier
My directional control is based on the rudder input in timing to the rotation, something developed on the simulator and foamy. To turn one way, I input rudder sooner to turn the other way I input rudder later. I would not consider myself a good roller though…only rotate one direction & some days are better than others. [8|]OK. I am a stick banger.[:)] As far as the tail going up...my guess is that that is the nose going down;turning will take more throttle (power)to keep the nose up. Good flying to you!

RE: prop for U Can Do 3D .60, os 91 fx
Here is the ultra thrust I am using: http://www.pspec.com/results.asp?category=8 It is the sport muffler & not the racing. I also have a 3/4" spacer & that may help with the lower RPM tune. The muffler is louder than stock, and works fine for 3D on 8 to 10 pound plane. That being said, I would go for the AX120 on a 8 pound plane and a FX160 on a 10 pound plane. My favorite 3D prop for the .91FX on an 8 pound plane is a SK wood 15x6slightly less thrust, but instant spool.

RE: prop for U Can Do 3D .60, os 91 fx
At one time had a 10 pound plane (GPSpacewalker) with a OS.91FX that I wanted to learn to hover with. I tried a lot of different props listening to advice from local experts and could not find anything that had the pull to hover. Then I found a .91FX engine test from Engine guru Clarence Lee who tached this engine w/various props: 13x6 12,500\13x8 10,400\14x6 10,900 \15x6 10,200 \15x8 8,100\16x6 8,300. Using this prop/rpm information, I plugged these numbers into a thrust formula published in a magazine. The clear thrust winner on paper was the 15x6 @ 10,200 so I tried it and I had a winner. It had very little pull out, but enough for up high practice. I also noticed that my fuel usage noticeably decreased. I then picked up a high volume Ultra-thrust muffler (tuned for lower RPM—I think the tower .75 muffler is lower volume & is tuned for higher RPM). My .91FX was turning the lower 10’s with an APC 15x6 stock muffler, baffle removed. When I put the high volume ultra thrust on, it jumped to the high 11’s!! This was a dramatic increase in thrust; pull from hover was very good—enough so that I felt comfortable hovering on the deck. I can say though, that with the way I was using the left stick, my fuel consumption went way up(I was using HP). The .91FX with high volume Ultra-thrust is now on a 8.75 pound plane (4*60) and it easily wins a vertical drag race with a 10.5 pound/1.6FX plane .

RE: os.91fx (RINGED) what prop?
My testing has shown the best prop on a .91FX for ultimate thrust is APC 15x6 (should turn around 10,500, if I remember right, and pull about 12 pounds). A little less thrust but instant spool is SK wood 15x6-my choice for 3D on a 8+ pound plane. It sounds like you have plenty of motor for the plane and don’t need the best thrust? If you are around 7 pounds RTF and have a good running 91FX, anything from a 13x6 to 15x6 will work. I have not found a thrust benefit to 4 pitch props 16 inches or larger. I did have a 16x5 wood that worked well a SA100 and FL330. Tianci is right; load the .91FX with anything more than a 15x6 and it falls on its face.

RE: Thrust needed for 3D
[quote]ORIGINAL: PE2fan Hey guys I was wondering what thrust is needed for comfortable 3D flying? The combination I am looking at should give me 15.4lb to fly a 12lb plane. Is that too low to for good 3D? Mike [/quote] Is this a real measured 15 pounds of thrust? If so, I have found that a 10 pound plane with about 1100sq in of wing loading is about as high as I like to go. If the wing area goes down to 900in, then I like max weight to be closer to 8.5 pounds. This is at lower elevations.

[quote]ORIGINAL: RaceCity I have a Saito .72 (APC 13-4W) on my Fusion, and an OS 55AX (APC 13-4) on my Edge V3. Both engines are similar in weight, and fuel consumption. Both engines run well in this sort of application. Performance wise? The OS 55 hands the Saito it's proverbial a$$. No comparison. If I had it to do all over....The Saito would be in a Cub where it belongs, and I'd have put the OS in both the Fusion & the Edge. The OS has the better (faster) transition, is much smoother, and believe it or not....the OS has a more linear throttle response than the Saito. The added bonus is that it costs about $75 less while giving me fewer things to maintain. The Saito is nice, but for these airplanes? The OS gets my vote.

RE: Brillelli 40GT and QQ 73" yak thread.
My B46 has the WT 349 carb with a fine thread on the H speed. It has the standard velocity stack that protrudes out the cowl ~.125. This carb does a good job at metering fuel on the B46--I have found the H & L needles to be very sensitive. If you are not happy with the pull of the B40 on your plane trade it in for a B46. You will be adding 6 to 7oz to the nose though(if you are already running the lite muffler).
