@@rcpilotwill Interested in what Chris 😏 comes up with to reinforce the area. Maybe channels cut with carbon fiber square rods glued in or some marine plywood in-laid over the area? 🤔
Glad you were able to get it down safely!! That woulda been scary for sure! I still have yet to maiden mine due to weather but will be paying attention to all these videos before I do!
Excellent and calm piloting, Will. Thanks too for all the information in the Videos. I'm hoping to assemble mine in time to fly next weekend if weather permits. As we fly from a grass strip which is still a little rough from the dreadful weather we're having in the U.K, I will be sure to regularly check for the kind of damage you exposed. Also, from past experience I tend to apply a firm tug test to all my EPO EDF a/c control surfaces and re-glue as necessary.
From your video, it looks like the fuselage buckled behind the gear and blocked the wing from sweeping. I just happen to have a wrecked fuselage and there is an 8mm carbon tube right behind the gear bracket in the fuselage. Unfortunately, the tube touches the bracket but that's it. This leaves a weak spot at the back edge of the swept wing spar mount. If they had just extended that LG bracket to create an insertion hole for the tube that would have reduced the chance of buckling the fuselage behind the gear.
Wow, nice that you were able to save it, bro. Hot mess, people paying big money for these things just having to spend time and more money on repairs that should be addressed at the factory. Grrrrr They need to hire me for the ir R&D team. I'll tear some shit up and find all the weak spots. 😂
So I am going to say this much. I believe it's an oversight on manufacturing in the parts that pertain to the wing sweep mechanism. The structure that is housing the pivoting mechanism is too weak to support the either intended or unintended design, dual purpose function of supporting the main landing gear and wing sweep feature. In either case I wonder when this product was test were the take off and landings were on smooth geotech or grass ops? With that being said perklhaps this was not caught during testing because for the most part the testers themselves are skilled pilots and knew exactly how to fly her in under power, but still product specialists, designers and manufacturers need to keep into consideration the grass ops pilots, which are a lot of us because not to many of us own or fly from geotech turf. It's either asphalt or grass. No excuse, product has to be tested out for bad landings as well. I believe freewing will do the right thing and either create a reinforcement kit or have a stone cold failed plane that won't sell do to its increasingly bad reputation that is becoming an epidemic in the hobby.
I believe the product is good. Just somethings they have to find thru beta testing and we are the testers at our own cost. But just like the MiG-29 Twin 80 they made things right.
I got one myself havent maiden it, ive talked to some more experienced pilots than myself and everyone said this bird is great in the air but its a handfull on landing and ive see alot of crashes. Idk i may just keep this one as a static model. Btw new to your channel bud i gave a like and sub
Hey man thanks for dropping by and thanks for the sub and like. The jet can stress you out but landing it can be a challenge. I have a setup and mixing vid I will be dropping soon.
Every time you bring up the shortcomings with his jet people get all crazy and say its the pilots fault. I don't think so when so many have had issues. Glad people are working through it.
My man Rcpilotwill needs to be given kudos for discovering this flaw in design and pulling off a miracle of a landing. Now its time for me to get in my white lab coat and do my thing 🤓🧐
Once again, why didnt they extend the plate 2 to 3 inches back above the retract? They stated that they fixed the problem from the 80mm, once again there is not enough support above the main retracts! Your landing was beautiful! It should be able to withstand some minor roughness in a field. Im happy that i didnt pull the trigger on this plane. Just ask fat guy flies rc!!! Robert
Taxi, take off, and landing on grass really stresses the foam and landing gear on planes. Its really only a matter of time until something breaks. One of the fields i fly from doesnt have a well maintained grass runway. Its literally just a field. Theres a paved street next to the field that we use to take off from. Then use the grass to land. Its one of those areas where you have to choose between risking running into the sidewalks or land on uneven grass. Damned if you do, damned if you dont. No matter how good a pilot, every week someone either strips landing gear on the grass, or smashes into the sidewalk. 😔
Yeah its unfortunate we don't have a smooth surface runway but there is plans to roll the field. I like my field its nice but hard surface can hurt to if you drop in to hard lol.
I was at an air show when someone asked if 1 swept 1 full out wing ever happened . My father who worked for Grumman designing and testing the f14 quickly said no it never happened because Grumman had a steel bar that prevented that from happening. The pilot said it did happen once when one of those steel bars snapped due to chaffing. He knew this because he was the pilot that it happened to. He called in a mayday and was told he had permission to eject and lose the f14. He decided to try to land and had to fly with full left stick but he did manage to save the aircraft and land the plane ! You have to have big attachments to be a fighter pilot !
Maybe some carbon rods through the foam and a carbon plate epoxied on the top? I do wish the servos where closer to 30g. I think they need to be strong enough to press the wings against their bump stops. If not then its purely the servo keeping the wing where its at. I dont trust my left wing servo. Seems like it needs more torque
Well like every new car something is found flawed. These rc planes won't be perfect. Even if they remedy one thing something further down the road will happen. Thanks for watching. I hope you enjoyed it 😊
At an air show I spoke to an f14 pilot that this actually happened to. He managed to land the aircraft even though he had permission to eject ! The f14 did things that were above the design envelope. It had very few kills in its service life because when the enemy knew that f14 's were up, they stayed far far away from them !
100% the planes fault everyone I follow/I know who has this plane has had issues with it, mixing board glitches, servos freezing or getting bound up, I mean these issues never happened with the twin 80s so frequent.
