My Kitfox 3 cruises about 70 mph at 5600 RPM on my 582 (3 Blade GSC Ground-Adj). I nearly always cruise in the low 60's at 5200, however...As far as 'Fox's go, I know I'm slow - but I'm looking for just a little bit better cruise performance. My x-country from Maine to Virginia was slow going this summer ;) Anyway, GSC says that cruise speed increases an average of 15 mph...I would be happy as a clam if I could get 85 mph out of my bird, but I'm sure that 15mph number is for a "cleaner" airplane...They have no numbers on what the prop would do for a model 3, and my research hasn't turned up anything either. I asked Rich at GSC if I could purchase the prop and see what it did for me...another 5 mph is NOT worth an $1800 hit. He basically said that he didn't want a prop sent back to him because they were hard to sell... I tried warming him up, saying I'd be the "test-ship" for a GTA prop on a model 3 Kitfox to no avail. So, if anybody has any comments or suggestions, I'm all ears! I would love to cruise at 85 mph, but I don't want to touch the IVO in-flight props...the brushes just "giving out" make me less than excited about them. Has anybody had any dealings with GSC about their in-flight prop? Thanks a million guys! Andrew On the road to retirement?

I have a KF 2 and can cruise at 85 normal cruise is 75 at 5,600, 80 at 5,800 using a IVO ground adjustable. Dave I hearthe IVO has a better system for the brushes.... ________________________________ Message 4 _____________________________________ Time: 09:11:31 AM PST US From: "Fox5flyer" Subject: Re: Kitfox-List: GSC GTA In-Flight on my Series 3 --> Kitfox-List message posted by: "Fox5flyer" The greatest thing about the inflight adjustables is that you get the best of both worlds. Max performance takeoff and max cruise. You don't have to compromise. I have no experience with the GSC GTA, but I will say that any cockpit adjustable prop will give you a much better cruise speed than 70 mph. Of course this is all depending on drag with the gear and struts the biggest culprits. IVO has a unit that is long past the beta testing stage. It's light and from what I hear, fairly reliable. You'll save a lot of gas too and at today's prices...

Comparison included same gross weight, temp.,altitude. etc, engine rpm 47oo, MAP 24.0 on the subaru 2.2 liter with 69 in. IVO ground adjustable prop. Then we dropped fuel consumption from 8 gph to 5 gph by installing the fuel pressure regulato from Eggenfellner. This deriches the accelerator flow that the computer calls for at high MAP automobile throttle settings. ________________________________ Message 6 _____________________________________ Time: 10:41:51 AM PST US From: "jdmcbean" Subject: RE: Kitfox-List: GSC GTA In-Flight on my Series 3 --> Kitfox-List message posted by: "jdmcbean" Andrew, Lift strut fairings will be one of the biggest gains... If you do not have them. I'm a dealer for IVO and brushes just "giving out" has not been an issue. Over 300 hours on mine... and several more on those that I've sold. Has anybody had any dealings with GSC about their in-flight prop? This was 5 years ago and I have been told GSC has fixed this issue.. after approx 100 hours on a 912S powered Series 6 the thrust bearings started streaking oil out onto the blades and around the hub.

No Jury Strut Fariings, and no Wheel Pants...I've got those big 'ol lawnmower tires too. Also, I'm trying to make sense of how these in-flight props work with a 2-stroke. I'm a PP with Complex sign-off, but I'm lost with this 582. Some questions: On climb out, I obviously want max RPM. When I level off, how do I decide where to set the RPM before increasing pitch, and how does this affect motor performance/life? Why don't I just keep full throttle and back-off on the pitch? GSC told me not to do that - but couldn't tell me why...Is my fuel burn decided by the rpm I select before or after the pitch is dialed in? Thanks again!

Lets say, on Climb-out I'm running 6500. I level off and rpm's jump to 6800. If I had the in-flight prop, which is more advantageous/economical to do: Keep the throttle wide-open and increase the pitch to bring engine speed down to 5500, OR throttle back to bring rpm's down to, lets say, 6500 and then increase the pitch? Don't know what to do with the throttle LoL...

BTW, before the Jabiru I had on my model 3 the same engine and configuration as you and saw about the same performance. Cruising along at 70 MPH? Why not?

I even flew all the 11 hrs to Virginia at 5200! But let's say I were to cruies at 6300 tomorrow - and I get 80 mph...IF were to have an in-flight prop, and I set the throttle at 6300, then dialed in the pitch to bring it down to 5200 or so, would I see that SAME 80 mph?

Paul Seehafer +++++++++++++++ Subject: IVO Prop Any of the Listers that could offer an opnion regarding the electrical IVO prop? Regards Hugo +++++++++++++++ Gary Algate wrote: I have the 72" Electric IVOPROP on my lite2 582 and it is probably the single most effective addition I've made. With the GSC Ground adjustable prop I was consistently changing pitch as the weather changed and whenever I achieved the best pitch performance setting for the hot humid summers here I was then chasing high EGT's on descent. With the IVO you always have the best possible pitch setting for all conditions. I am now a little faster in cruise, a great deal faster on take off performance and use less gas. Another great feature is the ability to go to a really fine pitch setting on final to increase the descent rate without increasing speed, the roll out is also significantly reduced. Am I happy? Yes. Gary Algate Lite2/582 KFII/618 +++++++++++ Hi, Folks Happy New Year. As I've installed the IVO propeller, some might like to know my exp. so far. It's an IVO 66", yes- 66", IVO recommended 68" - but I'll found that this was pretty much on the edge for this kind of gear box, so I've decided to use the same diameter as before (with GSC) 66". The propeller type is: UL366Q (made the 8 of July 2002). This blades is the same as used on their in-flight adjustable system, so with this kind (yr.2002 mfd.) of blades upgrade is easy. I've learned about this propeller from a friend flying trikes and alike. I've noticed the ease of adjusting this propeller, just one (big) counter nut to loosen, then adjust the center screw and retighten the counter nut. All in all very easy to do, and the prop. is in perfect balance all the time. The first run up was remarkable, no unbalance and very smooth, I've later learned that; this is the trade mark of IVO. Well, the prop was delivered with the three blades, three (lets call em) hub washers, then the counter nut and the adjustment screw. Sure, there were six 8 mm bolts also ( 8 mm is a little more than 5/16"), thou without locking wire hole. According to the install instruction, the thick washer (1/2") has to be mounted against the engine flange, next is the blades, the thin threaded plate (3/8") with the preinstalled adjustment screw and finally the six mounting screws. Are you following? I've said three "hub washers" and the installation called for only two! Well the extra plate was of the 1/2" size. As the bolts length obviously included the extra "hub" washer, an e-mail to IVO revealed that this extra washer was needed when you had an A or B (Rotax) gearbox. If you look at the engine flange on those kind of gear boxes, you'll see there is a pipe stub extending some in the center of this flange. To avoid conflict during adjustment (be able to adjust the set screw fully in without touching this stub and limiting the adjustment span) they added this extra "hub" plate. So there will be two "hub" plates to the engine flange, then the blades and so on.. However, as there was no conflict with this stub in my setup, there was no need for three "hub" plates. Anyhow, I had to use all the "hub" plates to fill out for the bolt lengths. As there were no need for the "out" spacing of the propeller, I mounted one (1/2") "hub" plate, then the blades, next the second (1/2") "hub" plate, then the threaded (3/8") "hub" plate with the adjustment screw installed and finally the six propeller bolts. Without any idea about the pitch angle, I used the built in pitch, yes installed it so that all the adjustment arms are unmodified by the adjustment screw then fasten the counter nut. (Forgot to mention the propeller bolt torque, the required torque is 200 inch. lbs.) The first run up with full throttle ended at 5850 RPM, much to low - but I could not hold my fox with the brake !? First time this happened. After two or maybe three more adjustments/run ups, I've finally ended up with 6150 RPM. Well, how good is this propeller? Here is a brief before and after test: With the old GSC propeller: Test made at 2000' at 20 deg. C (68 deg. F) and 1020 hpa (mb). MTOW: 811 lbs. 5200 RPM CAS 59 Mph 5500 RPM CAS 63 Mph 6000 RPM CAS 72 Mph. With the IVO propeller: Test made at 1000' at 14.5 deg. C (58.1 deg. F) and 1012 hpa (mb) MTOW: 722 lbs. 5000 RPM CAS 64 Mph 5200 RPM CAS 67.5 Mph 6800 RPM CAS 85.5 Mph (full power) Now it's time to do some math: The idea is to find out how much power is needed to go at 67.5 Mph. By using this method, we can figure a drag graph for our Fox, or rather find out the most economical cruise speed for our craft. The relation between the delta power and delta speed in the power of three is well known. So here is the equation: P2/P1=(V2/V1) 3 ): We rearrange and have: P1=P2/(V2/V1) 3 Then insert some numbers.. P1= 47 (Kw)/ (85.5 Mph/67.5Mph) 3=47 (Kw)/(1.267) 3=23.127 Kw To se how much power in percent used to get 67.5 Mph speed, we have: N=(P1/P2)*100=(23.127/47)*100=49.205~ 49 percent of the avail is needed to cruise at 67.5 Mph under the present met. Conditions. Compare your slide position to this result. By sampling more speeds and just fill in the numbers, you'll find the minimum in the drag/speed relations for your Kitfox to determine the best economical cruising speed. Remember, all numbers to be used for realistic measurements must be done under exactly the same conditions. Yes, I'm very satisfied with my IVO propeller. BTW, here is the link to IVO prop web site: http://www.ivoprop.com/ Torgeir. +++++++++++++++++++ I love the heck out of 'em...I ran a Warp square tip for 100 hours and switched to the IVO. At the same static RPM, I got a little better climb and picked up 7 mph in cruise. The IVO flex is recommended for the pulse frequencies of the 2 stroke Rotax...
