I made some new gear for the machine. It is much wider, higher and more stable landing gear system. I have not test flown them vet but would like some in put. Constructed from PCV, I have seen some guys make mount like this and would be interested to know how well the worked.

Thanks in advance

Hope ya don't mind me saying - that is one freaky looking machine!

It doesn't really look like you need the extra height for the LG - why are you trying to get it higher? If you could use other materials to gain the height (other than PVC) it would look a bit more professional. Unless you really aren't concerned....

Not really trying to go higher more so wider and increase the visibility. Funny that some one that operate the under slung type of camera system would have concern about height. I have not had the opportunity to operate this type of equipment but it looks like they could fall over

No chances of this happening hear

Cost of construction was cheep and when I am doing R&D the best material is the one that is available. As for the machine well once add all the gear to the airframe for a fwd mount you loose a little bit of curb appeal.

But thank for the in put

Well, I hate to be a stick in the mud here but you did ask for input, so here it is.

When doing AP, it's all about weight. You just added quite a bit of unnecessary weight. By doing so, you are wasting fuel and creating more stress on the mechanical components of the heli. Not to mention decreased autoing ability. Don't get me wrong, it looks cool. But AP isn't about cool, it's about results. There's a reason you don't see any of the manufacturers using that type of pipe for landing gear struts. It's just plain heavy. You're already adding a bunch of weight by adding all the "Necessary" Ap gear to your heli. Why add more if you dont need to? Another unintended consequence is resonant vibration. You will most likely notice a "New" vibration that you never noticed before. If you're lucky, it won't occur at the exact head speed you are set up for. On the other hand, it could give you nightmarish problems. BTW any time you add height, you increase the possibility of ground resonance problems as well.

As for visibility, well I really don't think you're going to notice much difference with that set-up, when the heli is 600 feet (180m)away. At the very least, you should have different colors on the left and right sides, to give you better orientation.

Anyway, I'm not saying don't try it. That's what R&D is for. I'm just saying that there are better ways of doing it, and if you look around this forum, you will find them. Good luck.

PS. I miss Corey and Trevor.

Don't get me wrong I valued all in put. As for weight, it is not that huge of penalty. This machine full up weight is 11.2 lb. With the Raptor 90 landing gear install originally it had a full up weight of 10.6 lb and still offers 12 min run time for the OS32 engine with stock Raptor 30 tank. Visual improvement is the biggest advantage for me. Orientation is an issue on FWD mount like this but operating directly over head the profile is so narrow. Some guys are adding ball to the camera to give some improvement to viability.

Down the road if I am happy with the operation I could replace the PVC with carbon fiber tubes or scrap the whole thing and I am out $20. Next time you are at Home Depot check it out 3/4" * 1/8 PVC. It is pretty strong stuff, I didn't stand on it but I bet it would take it.

I wish I could test it out today but an ice storm is in progress
Thanks again

That thing is getting huge!

You just need to fly more to get a feel for the heli. (that is the excuse you give your wife) Besides, you can still hear that nitro engine even at 600 ft.

Dude the weather sucks this week, it can stay like this for much longer spring is around the corner. Me the wife don't talk about the heli's a bit of sore spot

Bigger is better that what she keeps telling me

11.2lbs on a Raptor 30? Did I get that right? I'd be looking for ANY reason to get weight down. You are way overweight IMO. You'll thank me later for warning you.

My stock Raptor is 7 lb I flew this machine at 10lb with 550mm blades. Now she runs 620mm blade. I had it up to 12 lb before no problem check out the video.

Well I like the PVC tubing Actually it is not heavy material and replacing it with carbon rods will not save you much if any weight. It is also very forgiving with vibrations as it is a soft, complient material a bit like HDPE. It is not very strong though so watch out when landing it in a hurry

Wide spaced landing gear with noodles are great for high altitude visibility. I depend on mine totally when shooting stills. I think this is a good workable design for stills.

I think that tubing is actually CPVC which is a lot stronger than regular PVC especially at elevated temperatures. You can make a wooden form and carefully heat the tubing to bend the shape and then you wouldn’t need the elbows. A continuous curve from one side to the other will be stronger and lighter also. A little sprits of black paint and no one will know it is plastic.

People laughed at me because I put $2 bats and a ball from the dollar store on my heli for better visibility. I laugh at them because they don’t think they need anything. Enjoy the hobby and don’t let the nay-sayers get you down. You’re doing just fine.

You got it Ace, some one has to think out side the box. Black paint I like it. May give the bending a try thats a good idea. This stuff is very strong.

Here some video I shot today.

Update

I took a little weight penalty but I think it was worth it in the end. One issue that I notice straight away was some vibration from the pool noodles that noticeably affected video quality. Just removed the pool noodles and the problem went away. I may try smaller pool noodle with smoother profile or just remove them for shooting video.

Conclusion; it was a success and I will keep them for now.

Are you using a stabilizer and the rocking is due to the mount or is it pilot inputs?

No deshaker or gyro stab for this flight, just flight test that I had done nothing planed. For the first flight I when up with pool noodle install, had some vibration coming off the landing gear that was transferred to the video. The second flight switched to still camera and shot some stills. Third flight remove the pool noodles could see improvement in the down link video quality but forgot to start recording. Forth flight recorded the video you see but was starting to loose the light. Whipped this video up that evening, not making excuses it is what it is.

I like it. I think with a stabilizer you will be sweet.
