Problems with Nose wheel assembly

[asra]

Ahhhh cool !Ok is the 2nd box tube like the first and also goes through the main frame tube and pinned ?Obviously a good solid method of attachment indeed ! thank you !.... and yah its a bit dirty.... but she earned it ! Mighty nice lookin gyro ya got there ! Sami I wouldn't mind a close up of the shock arrangement ya got on the upper landing gear strut ! eather O'l buddy O'l Pal ! You are just full of good ideas ! Thank ya !Bob....." Momm'a alwayse told me , Son the impossable is only a little bit Harder... and ya know I do believe She was RIGHT ! "

The box tubing has a solid block of alloy bolted in the end, then that alloy has 2 bolts that pass through it and through the keel, locking them together.The rear box tube is the same, but only has 1 bolt.The top H.S has 2 "L" angles bolting the H.S. alloy tube spar to the fin box tube spar. The rear H.S. is held down by a length of all thread that hinges the rudder.As for the upper strut, nothing special, just very conventional.The larger tyres work better than the strut.

Gotcha ! Thank ya Sami I was wondering how ya hindged the rudder , now I know THANKS ! and thanks for the Pic , thats sure a clean and sanatary method of doing it ! Nice !Thanks for the help !Bob......" Momm'a alwayse told me , Son the impossable is only a little bit Harder... and ya know I do believe She was RIGHT ! "

Sami !One more question if ya don't mind ... what and where do ya get the rubber for your nose gear ?I think Sonny asked ya 2 times and the poor guy got missed ! ... he's almost got his front end all done now and its lookin good !just needs the Rubber bumper in the thing ! is there a place you buy them from ?or is it an o'l tractor tire ya mulitated ? heheheheheh .... I'm sticking with purdy much solid landing gear on mine for now ... because of the weight considerations ... I have removed everything I can off the machineand am about to add my 4ft hub bar on there to give the added Rotor diam that I need .so what about that Rubber Sami !Thank ya Mate Your a welth of info ! and its greatly appreaciated !

The alloy tube used on the rudder has a ball bearing on each end and the all thread is placed through it and bolted to the top of the H.S, and bottom rudder mounting plate.The front fork suspension, is a modified Rosco nose wheel assembly, Im not sure were he gets the rubber from, but I know he will sell you one if you want. Details are as followsGyroscopic RotorcraftPH & Fax 08 80879148Ask for Rosco.I havent got an email address, maybe some one has. Regards Sam. []

Ahhh ! thank you Kind sir ! Bob....." Momm'a alwayse told me , Son the impossable is only a little bit Harder... and ya know I do believe She was RIGHT ! "

Sam you have done a great job just check leverage over rubber mounting plate bolts you apear to have moved the wheel back & this has increased the forces on the bolts at front. A mate in bundy did same as you during setup only had low grade bolts through & they sheared off when I steped off the seat onto the keel My sugestion drop test as per any new gyro 8" I think

[asra]

Butch : 8" drop test ? thats all ? how about 2 feet ! if your gyro can't stand being droped 2' without the rotor on it I think I would consider makeing it a bit strongerFOR SURE ! .... Just my opinion but 8" isn't even a good fist sized rock at 20mph ! I have dropped my gyro 2ft to the ground axidently while doing a haing test with no ill effects at all... beside a few extra grey hairs ! and having to repair the comealong that let go ....... granted I was not in the thing at the time .... don't think I'ed want to be eather ! 2 foot is a long way !but seriously ... don't you think 8" is a bit short for a structural strength test ? I mean if its going to break on impact with the ground you want it to do it then not later ..... heck man 8" is a feather soft landing to me ! HAHAHHAHAHHA !but what do I know ... ! Just a thought !

[asra]

Thanks Butch.I will keep an eye in it.Regards Sam.

bob if you wish to use the asra web site try & keep up with our testing methods & rule's the test I speak of any TA will tell you is the new standard test asra came up with for new airframes & suspension setups also in line with asra guidlines a student must get a min of 20hrs instruction before they can be a licensed pilot so please get some flying lesons

[asra]

Butch I don't have to keep up with the latest laws that hinder you folks over there just to use your ASRA website ! but thanks just the same for letting me know where the 8" idea came from .... kind'a figures actually in my opinion its not near enough ! seriously now ... if your a good pilot and never land hardand run on paved runways , 8" might well do.... heck just keeping the wheels on might just do as well in that case ... but think of it this way... sense the landing gear is subject to the most stress on the airframe, I would think having it stronger than it needs to be is a good idea wouldn't you ? simply hitting a fist sized rock on a dirt runway could easily put more stress than a 8" drop... i would think anyway ! and Butch you know already why I'm Not takeing flying lessons... I can't afford them and they are not available.... its impossable at this point in time.that hasn't changed and I doubt it will in the next 5 years ! Just my opinion ..take it or leave it !Bob......." Momm'a alwayse told me , Son the impossable is only a little bit Harder... and ya know I do believe She was RIGHT ! "

Guys, the drop test for gyros is only 8" because the rotor is still producing some lift. Not like a fixed wing where the aircraft "drops" when it stalls.When I was in NZ a month agao, I was talking to the manufacturer of the Bantam ultralight in his factory, and I believe that he told me their drop test for fixed wings was 30".Aussie Paul.

The other thing to consider is at some point you want something to give. Best that the first point of failure is not you spine.By all means build them tough, but keep in mind if for some reason you go in vertical, you want some form of progressive failure.Ross B

[asra]

Good point !Hope i never get the chance to test the progressive failure limits of my gyro ! I am fairly sure if i hit hard enough to bend the thing up into a ball I'm gunn'a be hurtin' ... So Paul that makes sense ! ... sense the rotor is alwayse creating lift you realy would have to hit hard to produce 8" of falling type forces sense 1/2 the weight would still be held up by the rotor ,.... Ok .... that makes alot more sense ! it scares me to think there are guys out there flying gyros like I started out with .... in a word ... a death trap ! .... but I guess their not as weak as I first thought ... my Bumble bee sure didn't inspire confidence with its Ruggedness ! hehehehehehhe ! but each to his own fer sure ! ...catcha later !Bob......"
