Official Freewing MiG-29 Fulcrum Twin 80mm Thread

Hi FlashJ,

I flew several thousand flights with the stock BEC. No issues, but I did not have the added electrical load of the TV. Don’t fly without TV….I did fly without TV and eventually crashed mine.

Oh man, I wasn't planning on adding TV. I'll try my hand without it. Thanks for the heads up!

Legends die hard when they do die. SPLAT!

Thanks.

After 2000+ flights though, you legend!

I still have the stock BEC in mine. I agree with Hugh though...

Hey guys, I've finally gotten around to assembling my Mig-29. Mine was shipped shortly after the elevator servo upgrade, so I have them and the solid pushrods. I've read a good number of posts about mods/changes to make to the plane prior to maiden. The one thing I haven't a definitive answer on is if the stock BEC "needs" to be replaced. I agree the wiring is a bit thin for the length of the runs, so heavier gauge wiring is recommend.
So the question is, keep the stock BEC or replace it? If replace, what minimum amp rating?

I installed the Castle 20 amp BEC pro. Works great! Most left the stock BEC in and haven't heard of any problems though. I used the Pro Modeler servos for the elevators (even though I got the upgraded equipment) and Hangar Nine Titanium pushrods (the upgraded Freewing pushrods still bend-trust me on that, but better than what it comes with) and installed the TV nozzles as well, so wanted to use the 20 amp BEC just to be safe. If you can, locate all electronics under the rear battery tray (including the RX and I used a 10 channel Spektrum AS3X and a Hobby Eagle gyro for the TV nozzles). Then installed the BEC in the raised center, with the 2nd battery all the way in the nose, along with a satellite remote RX. Makes for a nice clean setup and was still able to balance it 15mm behind the book CG with either 2 SMC 5300's or 2 SMC 6200's.

Nope, sorry...

have a link perhaps?

[xviper]

I would have preferred that scheme myself.

Picture was one of the Taiwan pilots with one.

Thanks John!

Pictures were posted about a month ago with a lot of speculation. If I had the choice of the two I'd prefer this scheme but no way I'm buying another one.

New from Freewing Model! New demo team scheme and installed TV option with 30g metal Stab Servos

Buy yours here while they last!

Absolutely. My reason to say use lighter batteries and (in my opinion) fly off pavement.

I'd advise to keep clear of really heavy packs. Not just will that harm flight performance, it will place additional (and totally unnecessary) stress on the airframe and landing gear, worsening wear and tear and accelerating component failure. Plus, it gets to a point where the extra energy of bigger batts is negated by the extra energy it takes to thrust it around. Going lighter will yield better results for the most part, particularly long term. My 10 cents ;)

The lion is not on the vertical stabs, but the rest are pre-applied.

A tiger, technically ^^

If you can handle or like the gracefulness of a pretty sluggish aeroplane (without thrust vectors) that needs two 6s batteries for about 3 minutes of motor time. With that nasty and costly habit of getting stuck in high alpha if you do some aerobatics.

You need a lot of batteries or the possibilty to charge at a high C-rate at the flying field.

You can fly the MiG for like 4-5min easily. 3min is akin to flying 80% of the flight full-throttle. Just need to learn some proper throttle management ;)
It also helps to keep the plane light and well balanced.
And high alpha locks are not a problem with the TV nozzles as demonstrated already ;)

Value is different for everyone. Is it worth the money? In my opinion yes. You get a very large and impressive aircraft for your $749 + $94.29. I would not buy this plane without the TVs. Not only does it help get you out of the alpha lock that has been mentioned but it makes it nimble, as nimble as a plane this big can be. Simply there is no other aircraft like it on the market today, to quote Nick Bolton on television.

But again, it is a big expensive airplane. It also needs two decent 5000-6000 size batteries, a receiver, and (in my opinion) needs to fly off pavement...

I get way more than 3 minutes on 5200's. But everyone is going to get flight time depending on their flying style (and quality of their batteries).

Totally second that line of thinking, but I'd add that I've got my best results with lightweight 600g 4Ah packs rather than heavy 5-6Ah lipos.
Not only you'll fly better thanks to a smaller wing loading but your T/W multiplies thanks to weight savings and you require less energy to keep aloft because a lighter plane is less draggy.

I definitely think this plane is worth the money, despite not liking many of the design choices that Freewing used in it. It still delivers something that is pretty much unique to the market at this point:

About batteries, do you know if it can take the Spektrum 6s 7000 packs?
I actually like to fly more scale just cruising around in slower movements, not flipping it around like a coin, but sometimes its nice to have the ability to rip it. with that kind flying, i should be able to get 5-6 mins on 6000, or?

Flipping around like a coin can be perfectly scale.

I really think we need to collectively get rid of that notion that scale flight equals flying just chill boring circles and 8-figures.
That's not SCALE, it's just chill. Nothing wrong with that, but aggressive flying can be perfectly scale, more so on a jet like this. ;)

I'd advise to keep clear of really heavy packs. Not just will that harm flight performance, it will place additional (and totally unnecessary) stress on the airframe and landing gear, worsening wear and tear and accelerating component failure.

Whose code of ethics are you going to use? Yours? Evan's? Mine? Trump's?

Who cares? I'm just stating that in my book that is fraud, so where is the problem here? What is there to argue about? I find it fraud. Period. It's dishonest. Period. It's my opinion.
I guess we could start a multi-page discussion about the legal implications, the philosophical aspects of being dishonest, might be fun, but I just have this opinion.
So, to answer your question: Mine. That's the one that interests me most.

[kallend]

I'm not talking about the legal definition of fraud; I'm talking about the ethical definition of it. Often a very big difference.
