New Avios Mig 17 ?

[Evan D]

I’ve got 7 now and everyone was a butterfly with sore feet landing. Totally amazing. Mines a little more tail heavy. Lift the nose wheel 1” and it sits on its tail.

Two more flights on mine this morning. Both were great and I'm starting to get the hang of the landings - only a couple of small, light bounces and one landing was near perfect. I think I may move the battery forward a bit to see if that will improve the landings even more. It's balanced just at the point where if I put it on its tail, it will just stand itself back up on its own. It teeters almost perfectly. I think I'd like a little more weight on the front wheel.

:partying_face: Wow.... Congrats bro! What a job.

WOW what a journey this has been!! Nothing was easy about this plane aside from getting the clear coat put on... Everything went wrong!!! Sequencer went out which meant I needed to bypass it and removed the inner gear doors which were a real pain for transporting with wings off. Then one of the ports on the Gear Controller board failed which meant I needed a Y (that I actually made at the field) cable to make it work. I didn't have any at the field so had to make on myself. Then while doing a preflight the nose gear and rudder servo stopped working... i didn't want to take any risks with the flap servos so I just glued the flaps in place and left them disconnected. Oh and then to top it off I forgot the LED afterburner controller at home!!! Needless to say it was a pain... but I did get it done! The plane flew great even with the issues noted above. Now I just need to figure out what servos to change out... battery for this flight was a 6s 50c 6200 Hobby Star pack that has bee very well used but still in good shape. After all the set up and the 3 min flight battery was at 3.85v per cell. I hope that this fan holds up because it is very efficient!!

A lot of people on the Avios Albatros and C-130 threads said their servos buzzed and then would die. I'm keeping my fingers crossed.

Mine works great (after I replaced the non functional flap servo), but some of the servos buzz most of the time, even when there's no stress on them. Usually I can make it stop buzzing by just tapping the servo with my finger

I've had the problem with quite a few FreeWing, Flight Line and FMS... This plane was okay. In fact it's bee okay about everything. It all works, nothing has failed and none of my servos even buzz. Four more flights today on 6200 and 8000 packs.

More than half of my servo arms were off center, easy to recenter them except for the elevator servos that are glued in. I made a small channel in the foam so I could get to the screw, it's on the bottom and no one can see it.
Definitely not like freewing or fms where they actually took the time to center them (mostly)

I think this happens more than one thinks. Yes, I had an ELE and a Flap servo that was "off" but more importantly, was different than the other side. I tried to remove the servo arm and clock it one tooth over but this made it sit too far the other way, so still no joy. I ended up putting it back the way it was and set it up the best I could. The plane seems to fly OK. The time this will present a problem is if you use full servo travel on full rate. Then one servo could deflect the control surface more or less that the other at full stick. In that case, reduce the servo travel in the direction enough to prevent travel too close to the end point. In the case of elevators and/or AIL, you could play a bit with differential to see if that helps to even out the surfaces travel. Otherwise, you'll just learn to NOT bang the sticks all the way to the ends if it causes a problem.

My repaint is coming along nicely. I'll probably make some waterslide decals later today and finish off the tail before moving on to the wings.

One question though, my elevator servo arms weren't properly centered. Anyone else encounter this?

Mine were close enough... enough for a Russian bird. If it was US it would be in the hanger. :)

I'm not sure if it will take off from grass. I flew off a GeoTex runway. It was the bounce up onto the grass at the end that tore the retract mount out. This plane lifts off at a very low speed, so it might make it off grass. It seemed to roll quite easily when taxiing back on the grass.

I have flown mine from grass, relatively well-kept grass. It seemed to require a much longer roll to get off, I mean it doesn't build up a lot of speed compared to some other jets (perhaps because of the drag from the grass, the wheels are relatively small), but other than that I had no problem taking off. Of course when landing the grass slowed down the model very quickly. The gear didn't have any problem handling the grass and the bumps. At least no problems so far!

Very nice video John, sharp and zoomed (not like the typical headcam). Oh, and nice flying as well!

Thanks! Ryan did good on the camera.

Was it the nose retract? Was thinking on upgrading from Mig 15. If the Mig 17 handles well on grass runways?

tore out one main retract

It's all fixed. When the retract pulled out, it pulled the wires and disconnected the connector behind the wing "board". The plastic mount that the retract is mounted to pulled out of the foam. The retract itself is very strong and well secured in the mount. That's the weak link, not the retract, so if you're just going to replace the retract with the one from the 15, it won't help. I believe the nose retract has a similar mounting system but the forces acting on it come from a different direction. I inspected the other main and that mount, too, was loose so I wicked in some foam safe CA and clamped it.

Maidened mine this morning - 2 flights. First one was the trimming flight. Battery (Gens Ace 5000) as far aft as possible - right up against that control board. It didn't need much elevator trim and only a couple of clicks of AIL trim. Flew very nicely, sounded terrific. As quoted before by someone, this thing floats right past you. The last 10 feet of altitude, it just doesn't want to come down. No flaps used, not airbrakes used for the landing. Second flight, just like the first, already trimmed so I just flew it. I'm at 3500 feet and it does big loops with ease. Even on high rates, it rolls quite slowly. Second landing used full flaps and activated airbrakes as soon as it touched down. It just kept rolling and ran up onto the grass at the end of the runway and tore out one main retract. Now it doesn't work. Will diagnose later.
It's not a real fast jet, but I guess it flies good enough as is, that it doesn't really need to be fast. It's a big plane and it barely fits inside the car whole. My SU-35 is easier to get in the car and I thought that one was "big". Once I fix the retract, another couple of flights and I should be able to land it better. If there are no mishaps or electronics crapping out, this one's a keeper.

Mig -17 is now turbined x-45 custom made tail pipe running cool good venturi effect going on ...
should be fun ....

the first Mig-17 that I saw fly in person looked like hat! Great stuff! Mine is still on the bench but it was figured out that the sequencer went bad. To me that is fine because the gear doors make it hard to transport!! ear doors coming out and sequencer will be bypassed... will get back to it this evening and hopefully have it flying this week!!
