Official Freewing 64mm F9F Panther Blue EDF Jet PNP Thread

Isn’t this a 3S max airplane and ESC?

Help required. I have built and setup my Panther. However, when I power up I get full thrust momentarily until the thrust reduces considerably. I have a fully charged 4S lipo. I also get 3 beeps from the ESC. Any ideas and how do I resolve? Many thanks in advance.

Make sure you have the correct throttle signal wire connected to your receiver throttle channel ( not the reversing wire connection ) Re calibrate the throttle. With the lipo disconnected and the tx on, push the throttle lever to full throttle, connect the motor lipo and as soon as you hear a beep move throttle stick to zero you should then hear 4 beeps. check that all servos are working then apply throttle and you should be good to go. ( assuming you have throttle cut switch on your tx off) There should be something in the manual that tells you this so check this out first !! Also make sure that your Tx throttle channel is not reversed before you do any of the above. Are you going to use thrust reverse ( probably not needed if flying off grass) If so then assign a spare channel to a reversing switch ( say a 2 way switch or momentary switch ) eg if channel 5 is normally a 2 position switch then connect the reversing lead from the esc to channel 5 on the rx so that this switch will turn motor reverse on or off to suit. Motion do a HOW TO video on this.

I have a bad shoulder due to rotator cuff surgery, so I needed a way to fly my Panther. If the Germans can get their rocket plane off of a dolly, why can't we get our ducted fan off a similar dolly?
I have used this concept to take a sea plane off of a wagon made of pvc and the process worked fine. Here are a couple of pictures of the dolly and plane sitting on top.

So, do you just place the plane on the wood dolly, full throttle and elevator to get the plane to take off ?

No duh...I just meant why did they just tag on to old thread instead of making a new one on Hobby Squawk.

[Evan D]

Because the squawk is the official site for Motion RC and RCG isn't.

[Russ]

Why did you refer to this thread from the new version 2 of the Freewing 4S Blue Panther page on Motion RC?
It's obviously just the old 3S version page.

I started a new dedicated page on RCGroups.com for the Version 2, for anyone interested.
Can't wait to get mine any day now from MotionRC.

Still my flying my 3S version with landing gear and bought it from the old Hobby Lobby store many years ago.

It would be easy to add the elevator servo for taileron. I suggest plugging the ailerons into aileron and flap and turn on flaperons. so easy.



Welcome to the forums.

Greetings! I am a life-long modeler and armchair engineer. Retired TV Producer/Director/Camera. The bit of "Hollywood" in me dictates that whatever I do needs to "appear" to be proportional and natural to my eye or within a scene or frame. My "eye" has served me well in video, print, model railroading (see photo), rockets, interior decorating, etc.

So, I am interested in RC flying at a slower pace to mimic the feel, as if I was observing the real jet. To that end, of all the affordable Freewing jets, it appears to me that this F9F would be the easiest and safest to modify in the following way: Add one servo to convert to tailerons, and use the ailerons as flaps. Thinking I could Y the rudder (?) channel and use the trim to lower the flaps for takeoff and landing. The F8 is an option, but it appears I would have to slice and dice to add servos to convert to flaps. I am very impressed with these smaller planes, including the smaller Inve$tment to crash ratio.

I very much appreciate your brief thoughts on my proposed mods, and your kindness!!

Here's how my 4s flys, so nice and easy

[rifleman_btx]

I fly mine on 4s 2200s, I have two, one with a stock fan with 60 Amp esc and th other with an xfly 4s setup and a 60 Amp esc. I cut out a slot in the wood battery deck and slide the battery sideways unto the slot. The esc is under the deck, not.quite in the nose. I do use landing gear though and so that might make up a difference in esc location for CG. They both fly great, so fun!

Every time I fly them I keep thinking, damn this is one I really wish were a 90mm!

Yes sir! Totally agree on all counts. And definitely for that 90mm!

I didn't see this thread but here is my setup. And I'm very happy with it: I just got the panther set up with my 4s system, got a 4 minute flight landed with 3.75vpc, 0 trim needed across the board with the cg spotted at the mid point of the aileron servo lead holes . It was perfect, and oh man, tons of fun. My setup was a 1800mah (claimed 75c) 4s pack up against the forward hatch point, mantis 65A (there is no kill like overkill) speed control shoved to the nose, the freewing 12 blade 4s power unit, had to shave some off the hatch for the strap to fit over the pack and under the canopy.

Will the stock motor take 4S if you change the ESC? Otherwise you have to change the fan (maybe a 11 blade unit) and the ESC.
Any suggestions ?

I have flown mine many times on a 4s battery with the stock motor and ESC. I never ran max throttle more than 4-5 seconds at a time, - during hand launch and a few high speed passes. I never had an issue with more than 20 flights on it. (crashed it after that due to lost orientation)

When I got the next one, I did change the ESC to a 40amp one, but left the fan and motor stock. - No issues with that one either. I have lots of videos of those flights on YouTube.

I love this airframe! We've had as many as 8 flying together.

I changed the whole system, esc, fan, and motor. It was easiest solution to just drop in the eflite system from their 64mm F15 which really made the Panther awesome
