Official Freewing MiG-29 Fulcrum Twin 80mm Thread

We’re being forthcoming!

[xviper]

Yes but if you get the TVs you won't.

And if you don’t get the TV, it may not last you long.

These are the greatest "one-two punch" replies I've ever seen here.

Rumor has it Santa is bringing me one to add to the hanger. It appears that between MotionRC and most of the mods seen on this forum, it's become a very nice airplane. My question is can you just cruse around with it like i do with my F22?

[Wild Man]

I knew if I started, I would be up all night. I started with the tail, ( Horizontal stabilizer's ) So far, so good. I was up all night.

[Wild Man]

Well I finally decided to go ahead and get one. After getting it out of the Box and Inspection done. All I have to say is What did I wait so long ?? Plan on painting this one RED' WHITE & BLUE. I have already started sanding the horizontal stabs

[fredmdbud]

But would he be willing to do the powered-descent-with-flaps scenario?

[fredmdbud]

Outstanding work!
Now the stabs deflect in a proper scale fashion!

Almost - there's some anhedral to the stabilators, too.

There's a "stump" portion towards the front to provide clearance due to this angle.

[heisteff]

Hi
here are some pics of the stabs (maximum deflection/way to high for in flight of course). yes the servo is not positioned optimal, but the problem is the space in the tailsection, the two balllinks help a lot to keep the "pushforce" straight (see pics). For the maingeardoors i have not had a idea to make it work without "wheelscratching" them, but who knows.

the white stick shows just about the correct lenght of the axle. hope it helps

Outstanding work!

Could you please send some pics of the model with the stabs deflected pitch up and pitch down? :D

That configuration should indeed reduce the stress translated to the airframe, the stress seen by the own stab and the torque around the shaft that a servo would have to overcome. But since you didn't change the servo angle and it still actuates parallel to the airplane's longitudinal axis, that kinda spoils the mechanical advantage of having the correct scale axis.
Ideally the servo linkage should act perpendicularly to the shaft. That said, the whole thing at least should translate to a more robust construction, more scale looking and more accurate flight dynamics to the full scale jet :)

[QUOTE=heisteff;n360168]Hi folks

roughly one year of work, here is my version of the mig

Wow!!
Masterful work!
enjoy flying her.

Thanks for sharing

Your airbrake set up is very intricate. I don't have the talent to do it. I was hoping that Motion was going to bring out the airbrake kit when they brought out the vector thrust nozzles.
Do you know if the airbrakes actually help reduce the ground roll after landing? Being such a heavy plane, my MiG rolls "forever". Airbrakes or reverse would really be of help.

Hi I don't really know yet if they do slow down the plane, but I would think down to a certain speed they would. She hasn't flown yet, that day was for pics and runway tests. My intensions are more for inflight use of the brakes (we'll see). It has nothing to do with talent it is just about patients making mods like that (about two weeks from the idea to finish, same with the cockpit ore the elevators)

At least yours can be jogged. Mine is often times in a state of permanent hibernation.

[Evan D]

Memory jogged…

I don’t remember FW or Motion saying an airbrakes was in the works.

the issue with rudder airbrakes is channel count as you need two additional channels just for that, steering and each rudder needs its own channel. Add the additional channels that TV requires and it adds up.

Not based on anything "in the works". It's based purely on what Alpha, C. MoMo and wolpertinger posted over 2 years ago.

If enough people order the MiG-29 PNP and ARF and we think the model has legs to support more aftermarket upgrades, we might consider producing other things such as an upgrade air brake set, also Sold Separately, shown below. But candidly, we're waiting to see how to model itself takes off before over-committing to more upgrades. We've seen it in the past where most pilots end up flying/loving the stock PNP model (which is great!) and the upgrade market fizzles.

We'll see what the community does.

Amazing model. Look forward to my maiden! Would love to get the upgrades for TV and air brakes. Please let us know when and where to order.

I read earlier that air brakes could be an option upgrade. Is this still being considered?

Motion doesn't "bring out" things. Free Wing does.

I'm 100% sure it helps as when I use crow and rudder air brakes on landing it very much shortens out my roll out.

You're correct, but the point still remains. That airbrake "kit" was supposed to come about the same time as the VT nozzles. I wonder what happened to the airbrakes.
I may have to do the rudder brakes in lieu of those airbrakes. I use rudder brakes on my Flex Pirana and they work extremely well but that's on a belly lander, so speed decreases long before touchdown.
