RE: Goldwing 50cc Pitts Python V3.
ORIGINAL: gjhinshaw Can you flip it? So it pulls from top?? Just asking....... I would have to go in abouttwo holes on the arm and cut some of it off to clear when I just eye balled it. I will measure it this afternoon to see exactly how much... I don't like the way it is either, got a pic of how you set yours up? Did you use an aftermarket arm? |
RE: Goldwing 50cc Pitts Python V3.
ORIGINAL: STATUS TUNING My factory pin hinges lasted one flight on the rudder so beware if you use std hinges, i have a feeling mine were damaged when "freeing" the glue after install (i use the brand "hinge" glue). Never had an issue before yesterday but the new robart ones are fine and seem much better made. I had the same problem with the hinges and changed all of mine, go back to post 74 and after. I took pics on how poorly mine were installed and how I changed them out.. Glad you didn't crash your bird.... |
RE: Goldwing 50cc Pitts Python V3.
ORIGINAL: scale only 4 me I'd flip that around too, that geometry is going to produce a lot of expo. Sad news,, I zigged when I should have Sagged and my Black Pitts is toast,, that's what I get for talking to someone while flying Scale, I agree on the Geo.. You should have seen the throws I was getting when I tried them out, it was just a little touchy...http://www.rcuniverse.com/forum/js/f...sn/biggrin.gif Man, this is sad news, hate to here you lost her..I hope that all your gear is fine and it's just the airframe and that you will still follow this thread if i promise to post pics of girls in bikinis once a week...http://www.rcuniverse.com/forum/js/f...sn/biggrin.gifGonna have some hook-up questions on the smart-fly...http://www.rcuniverse.com/forum/js/f...wink_smile.gif |

It does fit flipped around, but still has a goofy angle.. Whats your thoughts?http://www.rcuniverse.com/forum/js/f...spinnyeyes.gif

RE: Goldwing 50cc Pitts Python V3.
The control arm screw hole pretty much lines up with the center of the servo, so it's going to be the same no mater what wayI go... I will try a smaller arm later today to see if I still get the throws I need...

RE: Goldwing 50cc Pitts Python V3.
My arms were not nearly that big,,, Ya might want to think about relocating the servo higher.
The Motor and Radio gear all looks fine,, apparently Gold Wing had engineered crumple zones,, namely the fuselage ;) |

Were those the arms and horns that came with the kit?
My servo arm is half that size and I get (got) plenty of throw |

ORIGINAL: scale only 4 me Were those the arms and horns that came with the kit? My servo arm is half that size and I get (got) plenty of throw Yeah,that's what itcame with... I am going to do away with them on the elv. and just use them on the ail. Could you do me a favor and measure yours from the screw hole out, I see another trip to my LHS coming soon.. I ordered the Hangar 9 pilot today, should look good sitting in the drivers seat... New problem setting up the pull pull on the ruder, the arm was to big.. It wouldn't clear the former and I had to cut it down, now the linkagehits.. I am going to try going in on the holes and see if it clears.... I will post pics later... I'm trying to figure out where to attach the flying wires to the stab, it has a block glued to the front of the LE and to a rib.. Gonna look at your pics again,are yours in the LE or that block? |
RE: Goldwing 50cc Pitts Python V3.
I looked at the pics of yours again, looks like it's in the block....http://www.rcuniverse.com/forum/js/f.../thumbs_up.gifBack to the shop for some more fun!

RE: Goldwing 50cc Pitts Python V3.
your servo arm and pushrod linkage should be at 90 degrees instead of your servo arm being 90 degrees in relation to servo. need to move your servo arm a few splines so linkage and arm are at 90 degrees. but at full deflection the linkage will over center and move control surface in opposite direction. (unless you set servo endpoints so it can't over center) poor design in servo location on that model

Flying wires are done and I am pretty happy with them, added a ton of suport and easy to adjust... Scale gave me the idea to use the fishing leader and it worked out great, I went with the nylon covered steel 45 pound, dubro rigging couplers and a dubro 4-40 quick connect and a little shrink tubing.... Jimbo </p> |
RE: Goldwing 50cc Pitts Python V3.
Jimbo,
The servo arms are just 1", control horns were about 1.5" out, High rates were set at 140% with -75 expo, Low 90% and -60 (futaba) High rates gave me about 45 degree deflection, I never measured to see exactly what is was. Lets just say it was plenty. ATV set at 90% up 75% down, max before binding Ailerons were the same arms/horn distance High 100% -70, low 60% -40 (but ATV was set 140% so I maxed out the travel that way) Why they gave you those ginormous arms I don't know,, you'll have to reduce your end points so much?? . I didn't realize they were that big when you showed them being painted. I just don't see the point in using arms that big. Also my Rudder was set up 2-5/8" arm, just under 3" horns, crossed wires, high 100% -50, low 65% -70.. Rudder ATV was set at max not to touch the Elevators but around 100%. Hope that helps,, |

Hope that helps,, I think the arms they gave me would be better suited for a 100cc airframeif not bigger, they probably just have a big box of them and send them with every kit.. I got the rudder working good, had to go to the closest hole to get clearance... Going to work on the throttle this morning, that should be pretty painless... I am also putting in my graphic order, got a few things in mind to finish it off.. I am getting excited to see her all back together! |

Here's a pic of the rudder now, everything clears.....
Ahhhhhhhhhhh, the cowl that was a pain in my rump! Well I wet sanded the last coat of primer with 400gtand shot the first coat of color, what a difference.. Can't see all the ugly seams any more and it's nice and solid, the EzeeKote and glass did an awesome job... Couple more coats of yellow and I can start doing the other colors, 4 in total..........http://www.rcuniverse.com/forum/js/f...ey/msn/eek.gif |
RE: Goldwing 50cc Pitts Python V3.
Looks much better,, I put those spare parts up for sale in the marketplace,, FYI ;-)

Mustang mine are the same and it flies fine, its not optimal but with electronic radios expo can be set to suit.
AUW on mine ended up at 6.87kg so it suprised me... my 50cc sbach came in at 7.2kg... Ive added some setup pics, moved the rudder servo forward so i could run less weight up front and by chance it also allowed a nice alloy horn to be fitted (wont fit in std servo position). It runs dual 4000mah 2s batteries up the front ( total 8000mah) and a Tech Aero IBEC for the ignition (run this same setup without issue for ages in other aircraft) the batteries are setup via a miracle dual switch.. Servos are High voltage 1218TH power HD's all running on their own channels via a DX18 and voltage and temp feedback via telemetry (rpm next few weeks) |

I finished up the throttle hook up and it's working just the wayI want it. I also got my fuel dot installed, kind of a pain on such a round fuse.My pilot came in as well, I will mount it tomorrow, just had to take a pic with him in there...lol
I'm having problems with matching the yellow on the cowl, as you can see in the pics it's to dark.. I'm gonna try on some scraps to see if I can get it better tomorrow... Moving on to the ailerons, but first, a bench cleaning is in order.. Man, the bigger the bench, the bigger the mess...http://www.rcuniverse.com/forum/js/f...sn/biggrin.gif Scale, any tips on how you programed you aileron servos? I plan on setting them up tomorrow and want to make sure I got them right before I put them in... |
RE: Goldwing 50cc Pitts Python V3.
ORIGINAL: scale only 4 me 5625 servos for the Ailerons, Running left side chn. 1 right side chn 7 , using the Aileron differential in the Futaba TX, Servo were matched via a Hitec servo programmer. Elevator servos are Programmer matched also. single 7955 for Rudder The procedure I used is like this, Mount the servos in the wings, pick which top or bottom you want to be the "Master", with your radio make sure the subtrim is at zero deflection and the ATV at 100% (note it is important the sub trim for the chn and the ATV stay at zero/100% during the set up,, you can dial it back later, so if you need to move you linkage in to reduce throw to stop binding do it and max it out later) Make sure your dual rates are at 100% too. If the TX is telling the Mater to do more/less than 100% you're never get a match. Adjust the Master servo with the flying trim button to get it centered to 90 degree. adjust the linkage to get the aileron set at center. Now with the Slave servo connected to the programer use the center function to center the servo, adjust it's linkage to center the Ail. Then with your radio move the Master to full throw and use the programmer to set the end points of the slave. Now once those inputs are matched what ever you do, subtrim, atv adjustment, expo etc. the servo should run together. When you go to the other wing, don't worry about the first wing's trim changing from center, you can adjust the Subtrim with the TX once you're done programming. Basically the same procedure for the Elevators Also, I found programming endpoints just about impossible without using the computer interface,, using the programmer without the Computer for anything other than reversing and maybe servo speed is useless. Good Luck |
RE: Goldwing 50cc Pitts Python V3.
Humm,, I typed that all up and then looked back and see you have Hyperion servos not Hitec,,, are those even programmable?

RE: Goldwing 50cc Pitts Python V3.
ORIGINAL: scale only 4 me Humm,, I typed that all up and then looked back and see you have Hyperion servos not Hitec,,, are those even programmable? Yes they sure are programmable, they plug up to my computer, pretty neat program... The specs on them are impressive as well, 226oz torque @ 6v and speed is .013. They are quick and center awesome, Fully programmable and MG.Beenusing them on another plane all summer testing them out and with what I put that plane through, I have all the confidence in the world in them.. At $35.99, they are hard to beat.http://www.rcuniverse.com/forum/js/f...wink_smile.gif |

I decided to stay with the yellow, I have a big graphic ordered that will be going on top and will flow onto the canopy.. Once that is on I can add the rest of my scheme and very few spots of yellow will me meeting up..
Here are some pics as to where I am now, big difference as to what it was.. I still have to shoot the rest of the red once the graphic comes in.. Scale, I know you could appreciate the OMG moments I had with this cowl, I had my doubts with it a few times that i would ever be able to get it to look good, but I couldn't be happier with the results......http://www.rcuniverse.com/forum/js/f...wink_smile.gif |

Here is the new arms installed, The last two are the throws I get at full 140%, didn't put a meter on it, but it's a lot...I know it still has an angle, but it's much better then it was.. I really don't want to move the servos if I don't have to and will decide after i fly it some first...
