Replacing the nosewheel

Hey guys, I need some help with a nosewheel replacement. I've tried to glue the nosewheel (pant) back on the front strut but it only stays on till I hit anything during a rollout and hit the grass. The first time I used CA and then epoxy the 2nd time. The little nut and end of the strut that fits inside the wheel pant are what's broken off. So the best I can do is to put the lower strut back into the hole in the pant and glue.

I tried to remove just the strut. I'm able to remove the 4mm nut at the top but the strut must have a clevis or some sort of retainer inside that I can't geg to without cutting something out. I'd like to just JR Weld or solder a new open wheel with partial strut to the lower strut that's still there but am open to any suggestions.

If all else fails I'll have to cut a square of the lower cowl out that holds the assembly in and put in a new one. If that's the case, what is the best filler, tape, glue, etc to complete the job. This would be the first repair I've ever done on a foam airplane. All my experience till this plane is in helos. Thanks.

I can't fully deduce what you're explaining Don. The front wheel pant is held in place by 2 screws, which in effect just 'trap' the axle inside plastic channeling molded into the pant halves.
Why don't you just order replacement parts? I believe all are available.

AFA gluing foam, there's a littany of choices available, but my 'go-to' favorite is Beacon Foam-Tac. Not easily available everywhere, but a version that is, should be available at your Wal-Mt Crafts section -- Beacon (same company) 'Quick Grip' in the yellow & green tube. Same glue, just slightly thicker. It doesn't dry 'rigid' as does CA's & epoxies; maintains the flexibility that's one of the advantages of resilient foam types.

Thanks Starhopper. I'll check out Wal-Mart. What broke on my bird is the bottom of the front strut. It's the threaded section at the bottom. Usually a small nut holds the bottom of the strut to the top of the pant. But because the bottom 1/4" inch or so of the metal strut is broken off, along with the nut, all I can do is try to stick the broken end of the strut back into the pant opening and glue/epoxy it in place. Part of the plastic collar at the top of the pant where the strut enters is also broken off.

But without a nut to hold it inside the pant, it's not so good a fix. The next option is to buy the entire front wheel assembly (FLZA6041, out of stock everywhere, Tower, Adavantage, HobbyZone, so far) and carve out the old one, glue in the new one. I've tried dropping out the strut by removing the nut on top of the strut but it doesn't come out. It feels just as tight, still moves up and down on the spring inside but won't come out. So I don't see a way to repair it, just replacing it, or trying to put a different wheel at the bottom that would be soldered to the bottom of the strut

I have the FLZA6041 on order but I'm open to another wheel that could be attached to the broken end of the strut if anyone has any ideas. I thought maybe I could do a little wire wrap and some solder to another metal strut and wheel would be a good alternative until the 6041 is back in stock. All I need I think is about half an inch of a new strut above the new wheel to attach to the old strut still in place.

Ah so....
I see a couple places are expecting them either in or to've been shipped by Dec.15, so not much longer wait hopefully. Good luck with it!
(Frankly, I thought they way they constructed the whole rig was kinda chintzy. Not much latitude for repairs & maintenance for what's a naturally stressed part of the plane!)

Don..allow me to help you out....same happened to me as the threaded end of the strut broke like yours, and NO, it cant be removed your way from top.....

if you go back a bit and search I am the one with the post that tells you how to remove/replace the ENTIRE assembly is a pain(done from bottom and some surgery is required as FZ didnt make the part accesible a huge fault of this great bird...


...buy an AXLE AND COLLAR,,,2 $ and ya are good to go, attach the collar to the strut end(thats broken with threads missing like mine was) and then the axle to the collar with a wheel attached....a qucik fix as gluing the plastic as you say will NOT hold under any landing,,,this fix or the full suregry,,,up to you.... hope ya get her out again soon, not a bad flyer she is, despite her shortcomings.....

cheers

I think we all agree, Hobbico couldn't have made replacing the nosewheel much harder than if they had tried. My email to Tower Hobbies recommended I not try to take the lower cowling off. But eventually it will require major surgery to get the nosewheel assembly out. Maybe I can fashion a way to reinstall the new one with some screws thru the plywood/plastic top plate with some prep in the hole taking out the old one will create?

Just Fly, forgive my noobieness, but is there an specific Axle and Collar I can get from my LHS (HobbyTown) or is there a generic one that will fit the 3mm strut? My LHS is 25 mins away but I'll make the trip if they've got an A&C that'll do the job.

BTW I got the CG perfect with 1oz of lead scattered around the nose area with 4 pieces of 7grams each. It flew on rails for the one large loop I did before I did the touch and go that didn't go, at least not as planned. It was going so well until I veered a little off the paved area into the grass. Then BOOM, nose over when the nose snagged in the grass and the front wheel came off. Prior to this I've had 3 days of flying/fighting the tail heavy CG. Still using the stock 1800mAh batt and had dreams of switching out for a 2nd flight with an extra one I bought.
Next time, there's always the next flight.

Don,

One possibility would be to thread the remaining part of the strut, then use a bigger wheel. You'd also have to modify the wheel pant a little, for a wider bolt, but that's less of a problem. I guess you could file flats on the strut above where you've threaded to, to help keep it aligned.

Die sets can be very expensive, but it's sometimes possible to pick a simple one up really cheaply. I have an M2.5 to M8 die set, with a handle for the dies, that cost me about $5.

Hey Andy, you might have something there. I had thought about that but it's one tool I haven't collected over the years. If I can find one under $10 I think I'll try it. I measured the strut and it's 4mm OD. How do I match the right size & type of threads to go on there? Do sets come with a std thread type? I still have the nut from the bottom bottom part that broke off and it fits my 5mm driver. Don't know why they didn't make it the same as the top one which is 4mm.

I don't think it will help to file a flat spot above the threaded part. Half of the plastic neck on the top of the pant with the flat section in it broke off too. That pant comes with the whole assembly and it's already on order. Can't just buy it alone.

If I could get a nut on top and below the pant on the threaded part, it might work but the collar and new wheel are sounding easier as I think about it. I'm wondering where am I going to find a 2nd 5mm (13/64") nut. Thanks for the idea anyway. We'll see what I can find. It may not happen this month unless that assembly comes in. Even then I've got plenty to do over the holidays. Merry Christmas everyone!

Hi Don,

Yes, if you do it, the easiest way would be to thread it to M4. I agree, there may be easier ways though.

Sets are usually either all metric, or all fractions of inches. Metric is probably easiest to find cheaply on ebay, though there'd be the usual couple of weeks or more wait to import one. In the UK we're pretty much all metric on nuts and bolts, apart from things like classic cars and motorbikes. There are a few things that still use BA sizes, but not many.

I found a 4mm while plastic axle block is easy to fit to the strut. A couple of pages back I showed pictures of a shopping trolley style caster wheel I put on mine, using one of those blocks. Maybe you could use one as a bracket to attach another leg. It's not pretty though.

Wow Andy, those pics are nice. I remember seeing them but that kind of work is way beyond my current capabilities. But I really like the idea of larger tires without the pants to hang up on grass. Do you have a link or part # to the nosewheel (and main gear) you installed? It looks solid. I'd rather turn this into a rough field flyer if I can get the parts. I haven't joined the local flying club yet and their field isn't paved. Once I can get the nose wheel fixed the rest looks much easier. The stock stuff won't be in for weeks I think. Thanks for the advice.

You're welcome, Don.

I gave a link for the undercarriage set in the next post, but I fell for the trick where rcgroups gives a link to just one post, out of context, when I added the link to that picture..

The plastic parts were out of this sort of set, from HobbyKing, but I bought mine from giantshark.co.uk:

http://www.hobbyking.com/hobbyking/s...teerable_.html



The nose wheel was one of the two bigger ones out of that set. The mains wheels are the 75mm shock absorbing ones from giantshark.co.uk, but I think they're probably sold in a few different places, maybe HobbyKing too. All that stuff comes form China, wherever you buy it:

http://www.giantshark.co.uk/shock-ab...-p-402825.html



This is the (ugly) white axle block I used:

http://www.giantshark.co.uk/front-wh...-p-402843.html



- that's the strongest part though.

It wasn't hard to do. It just took some filing, with a needle file, to extend one of the holes in the block to line up with part of the new plastic undercarriage piece.

If you did the same, you'd have to go with smaller mains wheels, or bend the legs so it sits lower, because you've lost a bit of length off the front strut. I put a piece of thin brass tubing over the thread on mine (just forced it on by twisting), and part of the block clamps onto it.

These look like the same 3" (75mm) wheels from HobbyKing, that I used for the mains, but sold in bags of 5. Their search facility is crap, so it's possible they sell them some other way but I can't find it:

Thanks again Andy. I think the wheels will be the easiest part of this. A set of 5 will be good too. The do wear out and eventually I plan on getting a warbird that might be able to use them. I think the larger setup will also bring the CG forward which will be good. Now just gotta figure out what else I need to make the shipping worth it all.
