Official Freewing 90mm F-4 Phantom II Thread

Good Mornin' Vietnam ............ Sorry to disappoint you F4 fliers but the king is back ! To cut a long story short.... get up and go went at the start of the year.. wife not so great and old age started to get in my bones but things improving again. Didn't risk the F 4 but took the Pitts out at the weekend with no mishaps so pleased with that.

Good to see Aussie doing well and a new Cap'n Bill flying the beast well. Landing? Come in long , nose high, full flap... control height with power, speed with elv. and you can get it to sit down nice as ninepence..... Very worthwhile practicing that.... way up.... to get the feel.

My grey Marine lad needs a motor and you .... Hugh, are causing me consternation.... 8s set up will empty my wallet.. new motor, esc and batteries.. (usual reaction for a Scotsman when money is mentioned) But, seeing how you and Aussie like the set up I suppose I have to go down that route. Keep up the good work, I have to spend a few weeks getting the garden back into some semblance of order..Have four lawns and six high Leyland hedges to cut so might be a while before I get the beast up again....but the will is back

This was the maiden flight on my Phantom. Love the airplane and had a very good first flight. Bounced the landing a bit, but a few more flights will help make better landing once I get used to the airplane. Love the way it tracks and flies; but, mostly love the way it looks. Almost want to buy a second one in the grey scheme.

If you do, I suggest the 8S. Loved flying the 6S Phantom so much I had 2, then converted one to 8S and found it incredibly better. Over 5 minutes on an 8S SMC HiV 5900. Then got a grey in 8S and not disappointed. Definitely one of the best flying EDF's out there. Now have an 8S Blue Angel and Jolly Rodgers Phantom. Life is Good!

f4u ausie , I hear you, Brother.

Until I bought my first Freewing EDF, I had never read, heard, or seen a servo described only by its' weight.

It does keep things simple but it does little else.

So, I go to my favorite hobby shop and ask the owner, "May have a half a pound of your finest 17 gram servos, please?"

I don't understand that criteria unless you are only buying your servos by the pound, kilo, ton or whatever.

If there is a more logical explanation, someone please enlighten me as I am truly ignorant.

We always differentiated the servos by physical size (Micro, Mini, Standard, etc), inch-ounces of torque, degrees of rotation, and gear materials.

Later by type of motor, coreless for example, and now digital or analog, programmable or not.

The servo weight does little to describe the performance, which is really all I care about.

I just finished pulling out a twitchy 17 gram right aileron servo of the Corsair and replaced it with a 23 gram servo.

What does that tell anyone except I need to add 6 grams of weight to the left wing.

Frankly, I just don't get it.

Best, LB

Or another 23 gram on the other side. MORE WORK. Ye i think the hi teck i put in was called mighty or mini something,,, (no not mini mouse lol)

[nuts-n-volts]

I'm with you, LB. The weight indicator tells just me one thing... don't expect anything out of it and be watching for failures. Broken gears or heating up or just plain ceasing to work. Ya gotta be on your toes if you fly them. I will admit, they have gotten better over the years. But, I for one, still don't trust them in anything I really care about. Especially, elevators. Those get changed out every a/c. At least, most planes have 2 aileron servos, so there's that. If you're in doubt, it's always better to replace them and throw them in a box of spares for the prop jobs.

My choices for EDFs and aerobatic... HiTec and ProModeler. As much as I like MKS and Savox, they are just too pricey.

Hey guys hope yas all well... got my hi teck servo in,, wow. My first foray into quality (non generic) servos,,, makes an awsome nice electronic, electric sound, the stock servos just do not,,...... so itchin for sunday morn.. and that first long 435 volt flight,, hrb s holding up well time alone will tell..

[f4u ausie]

Thanx to all 4 help👍👍

[rlcamden]

Replacing the standard elev servo with a hitech hs 5245 mg .... was using super glue to close the gap (hole) in the servo arm..... saw that on rc informer.... to take out some of the slack,, well it worked well,, but dumb?. Ass me inadvertantly glued the servo shut.. around the edge.. between servo and arm... mmm was to b first 435 per cell 8 s flight.. on sunday... so put in batts preflight. ( no elavator) oh well... question have u guys made a little box or simply glued new servo into foam, as factory, just thinkin bout future replacement

I used 3DHolger's support (Reinforcement elevator servo of the 1:11 Freewing F-4 Phantom by 3DHolger - Thingiverse) for mine. Printed it in ASA and glued it with FoamTac after replacing the stock servo with a hitech and upgraded to a 4-40 pushrod and aluminum control horn on the servo. No issues and have over 100 flights in it.

[Elbee]

f4u ausie, I'd sleep better with a box or a plate as reinforcement depending on the integrity of the foam after pulling out a servo again. Make sense? Best, LB

Same thing I said, Hugh. It's like when you're trying to light a match. And it won't light every time you strike it. Until that one time. Then, BOOM!. You would hear f4u aussie telling his wife, "Honey, I finally got it to light!!!".

Hi team again more learning to b had,,,, i felt the need to try. And charge my ,, standard commond hrb packs to 435 volts per cell ,, nihv on your charger.... was nervous,, fires bla bla... last night a 6000 6s no prob to 435 per cell... tested at around 4 minuts al37..... instead of 3........ so tnite after work,, 2 4 s 6000 hrb 8s volts per cell as u c 435 per cell.. pics for proof.. goina bench test for time let yas no

WOW, you got some major cajones! (Don't feel bad if you have to look up the translation of that common Spanish slang) Keep a fire hose handy and give us updates on any potential bon fires, I'll bring the marshmallows. I'll probably just have to look West one night and the skies over Australia will be ablaze and most likely be visible from Florida!

[f4u ausie]

5 and a half minuts 375 per cell
