Lets say if I was approaching this having never flown a Mig 15 before, it has a fat fuselage, split flaps (good drag) and a large inlet hole compressing the air...so from this I would expect a sudden deceleration on chopping power. In any wind the factor is increased, in less wind-less so. If the Mig felt heavy I'd expect it to hold energy and speed if the nose is dropped, I'd land an aeroplane like this from a full flap down wind pass where I could judge ground speed and start to set up a level, to fractionally nose high sit, so get the speed off down wind and then balance power and leave on through the cross wind/into wind section, landing in anything over 7mph wind I'd expect to have to keep power on all the way through the final approach and decent, once the decent rate was set I would expect to use power to arrest the decent, not haul on the elevator and generate a stall.
Fly it to the ground, not stall it onto the strip.
Landing on grass is much different to hard surface. Look at this high decent rate landing-little bounce! https://www.youtube.com/watch?v=ckRnpYwB0NE

middle part goes into the sliding part of canopy, to stiffen up
bottom part goes to the inside of the front windshield, both parts are formers so you can have a stronger canopy
if you wish to make it sliding you have to check this forum for the solutions that other builders achieved!

I had quite a few bouncy landings the first 20-30 flights, always as a result of too high landing speed...period. I tried different flap setting/speed brake combos, before I went for the "all the drag I can get" - setting. "Lots of drag and thrust" is what works for me..Today I flew the Mig for the first time in over a year, so I felt a bit rusty. Full flaps, speed brakes requires 1/2 throttle with my P80se. Since it was some time sice last flight, I was a bit on the conservative side regarding approach speed. As you can see in the short video, the landings are far from perfect, but well within limits
Looking forward to a nice flying season!

If you can, try using the AB only to slow it down, then on the last 10m close the AB and land just flaps. Do you run much expo on the elevator control?

Wondered if you were high, at 30% the small tail and elevators are not powerful, or stable. I run many models with expo, but it depends on the aeroplane. Try reducing to 20% on the Mig, you will have more feel when slowing. My GJC Mig is around 20%, I'm sure I could go 15% and not suffer.

Morning,
I did 2 test flights on my Mig yesterday as well. I didnt use my speedbrakes at all, just full flaps and about 20% thrust to pull the Mig towards the runway. Throttled back to 0% and just flared out. It is all about having the right speed. Too fast and it will be a bouncy touchdown. With full flaps slow flight is just incredible. I think the most difficult part of this plane is to get used to how slow it can fly.
(****ty picture, but all i have)
I am using a Behotec J66HP for power, which is sufficient. I use takeoff flaps because it looks and feels nicer and I need about 300 feet for a takeoff run at full power. For the record: On the second flight I turned on my gyro (Cortex) and I deliberatly landed a little faster than I usually would. The Mig wanted to bounce off but the gyro immediately pushed the nose back down and it settled down nicely. What I am saying is, if you want to add a little extra security to prevent boundy landings, get a gyro for elevators. As for expo, Ia used -25% (Futaba) but I am going to reduce it to zero on the next flight. I think that the Mig does not need any expo at all.
Cheers

Goose, I had my gyro settings on 30% only because there was little to no wind. I didn't use different settings for each axis. I just installed the cortex with the quick start guide and that's it.

I heard that too, especially for take off apparently. Didn't see a need for it to be honest during the flights and take-offs without gyro. A real joy is the gyro on elevators though as it reduces the changes of bouncing back in the air!

Pilot-figure for the mig
I`m in Need a good pilot-figure. I have the Chinese one w.leather-hood and all but I really would like one with a bone-domed helmet more like what was used with Warzaw-Pact Countries in the late fifties. Not neccesarely full figure. Any tips?

Hi,
I have decided to by the Powerbox Royal SRS with the I-gyro to use in my Carf Mig 15. I just realized that the JR 3421 servos (which im using on the elevators) are not gyro friendly I guess. Does anyone have any experience with these servos and gyros? There is a product alert when you look at the servo on Horizon's website. I really hate to go back and pull out the servos! Ive already got enough to do to finish this thing! lol I dont think the 9411's would fit in the stock location, but I'll have a look. Thanks for your help

Carl read your post yesterday, as I have your same setup installed in my MIG and was in an event with the manufacturer today, I asked him the question, was told to go ahead and use it and expect no problem with the 3421 / IGyro combination, reasons I was given where ok with me so I'm going to use it as it is.

Hello,
Take of doesn't need flaps, but with flaps it goes a litle bit smoother. Wen it bounced , don't pull up, wait until right speed and pull elevator smootly.
I do the landing with a big turn ( to keep a better eye on speed ), with full flaps and airbrakes, keep about half throttle and let it come in front of the airfield a few meter high and than go to idle. The plane wil lose speed and altitude rather quickly. I wait with landing until I can pull 'death stick' : no bounce and the plane stops after a few meters.

PS I'm also looking for a very light pilot, my mig is the '15' from Paul Entrekin first mig 15 in the US
