Freewing 90mm F-22 Raptor - Official Thread

[jasmith41]

Hi all,

the F-22 seems to be my next 90mm jet. I’m wondering if it makes sense to buy the 8s version. I’d like to start flying with a 6s setup and then switch to a 8s setup later when I’m more familiar with the airplane. What do you think, does this makes sense? Can you fly the 8s version with a 6s setup?

Thanks in advance for your advice!

6s

The 8S on a 6S battery may get off the ground (if flying off pavement) but it won't fly very fast, probably full throttle will be like 2/3 normal 6S throttle.

Thanks Evan! So, I’d better choose the 6s setup.

The nose gear mount on my new raptor is cracked by a rough landing. Ordered the gear mount set. Does anyone know how to get the nose gear mount out without destroying the fuse?

Turns out I was able to remove the nose gear mount with only one small piece of foam removed from in from of the mount. I used an X-acto blade to slice between the foam and plastic mount to clear some of the foam-tac type glue they used. Then used a pair of needle nose pliers to work it out from side to side until I was able to turn it out of the gear bay. Putting the new one in will be tedious but not impossible.

Okay so I didn't go through all 190 pages of this thread. I am ready to purchase this 90 mm F-22. But before I order I would like to get some real world opinions on what is the main flight differences between the 6s and 8s versions?
Pros cons of each.
Thanks

I don't have a gyro or receiver with a gyro. I mounted it behind the battery tray on the floor. I have two satellites, one in the nose and one at the right hand stab.

[jasmith41]

I have been looking at photos of the battery compartment of this F-22 and it looks like there isn't any flat surface to mount a receiver with a integrated gyro. I am going to use a Spektrum AR637T receiver and it needs a flat square with the plane mounting surface. Where have you guys been mounting your receiver gyro combos in this bird?

I think i mounted mine on the vertical side of the bay. I did mount a remote up front under the canopy hollow xviper refers to as well. RF chokes, etc., but haven't maidened her yet. I think i'm going to do that this week finally.

Issue resolved!

8S F-22 Raptor - ESC out of sync due to my error when setting throttle endpoints.

Trying to use the Freewing ESC programming card to reset the ESC and I can get it to power up. The 150A ESC has a separate BEC with a switch. Tried plugging up the throttle wire to BEC on the cardper the instructions and the switch to the battery port. No luck. The ESC will go be quiet for a few seconds after I plug the battery into the main ESC (EC5), then go to a single repeating beep like it does when it is waiting to sync to the radio.

Any help would be greatly appreciated!

Some more flying, no music this time ;)

For grass fields that are not as maintained as others yes it is.

our grass field is ok, but i still installed a nose gear brace, just in case, but i have to agree, generally the gear works fine, more than 100 flights and no issues so far...she is even not that prone to tipping as i expected ..you know her mains are not that wide, but also no issues so far

I made a crazy compilation :p

[Airguardian]

I also made a non-slow-motion version of it too ^^

[Airguardian]

Here are 4 of my most recent flights in slow motion showing the hands on the transmitter, in case that's helpful or entertaining ;)

My A3S3 gyro is under the wooden tray holding the battery, along with an external UBEC and plenty of excess wiring. That area is flat.

Also I would like to ask. Are you guys using any kind of reinforcement for the front gear? I see that there is a guy making a 3D printed front gear reinforcement. Is this or any other reinforcement recommend?

Haven't had any problem with neither nose nor main landing gear in 105 flights, so probably not really needed.
If it ain't broke...

I put the 637t (and a remote) on the vertical port side of the bird. Mid-canopy>front there's a flat spot that's relatively parallel to the long axis of the bird. In terms of programming, this is an acceptable orientation for the as3x, etc.. Haven't flown her yet, but will be shortly. I also clipped 3 coils off the front gear spring and 2 off the mains - to cut down on the bounce with grass field ops. Again, i have no idea if i will end up with popcorn in the end after either of these mods / installs, but it's just what i did based on what i've seen / heard. I'm going thru all my big birds and changing these things: 1. pulling rx antennae thru the fuse on 2 diff axis, 2. for $35, installing remote rx's onto the ar637t's (used the 8 ch ver in the FW F15), and putting rf chokes on the batt lead off the ESCs on all. I dropped a brand new Viper 90 Saturday and i wanna make sure that never happens again... (she's good, almost back together and flying again as well) what a great plane, btw...

if any of you veterans have any thoughts / suggestions on what i'm doing above, please feel free to share - i'm a sponge for this data...

Well said - stop the problem at it's source... :)
