Official Freewing 90mm F-16 V2 EDF Jet Thread

[Evan D]

The V1 with a modern 6S fan and good batteries flies very well and I expect my V2 8S to do the same. Should be faster than my other 90mm FW EDFs except the Zeus and maybe my JetFan powered F/A18C. The Eurofighter and J-10 as deltas have pretty high drag. Probably close to the F-22. My F-4 even with a 8S JetFan is not super fast.

When you look at this it doesnt seem that much speed wise, but then again its not really in perspective because its not in real life. i think motionrc would not just say random stuff like it is way faster in 6s.

Absolutely. Plus "Wes said"... But did he really fly them together or was it a generalized statement "I blew his doors off!", I did not in fact blow his doors off but I was faster...

Add to this generalized statement that he's not saying what version of V1 or of V2 or any other specifics. Even if you actually believe the half throttle statement.


Or I can take your saying "Wes said" as fact and be disappointed and want my money back when my V2 isn't as fast at half throttle as the V1 on 8S at my field...

You can't draw any conclusion about wing loading from that information (assuming it's even correct).

What it tells me is that the stock V1 power unit is not as good as the V2's.

[Evan D]

If you have two planes with the same thrust and wing (both don't have flaps for example) and one has a significantly heavier wing loading what is the effect you will see on how it flies? Mostly landing speed. Maybe a bit in how it turns at speed and it may have a slightly lower top speed due to drag.

Add more power to the one with heavier loading. Is the landing speed now better? No. Is the turning speed better, well it may be faster but it will have the same high speed stall. But yes, top speed will get better but you still do have a draggier airframe so if you had put that higher power fan in the lighter loaded airframe you'd be even faster.


What were the big issues with V1? Heavy wing loading and not enough room for good batteries or 8S (batteries then were a bit bigger and heavier than what I fly now). The V1 first had a low power out runner. Subbing in a newer 6S in runner has helped those that still have a V1 but back then my choice was going to 8S and JetFan EDFs. The V1 didn't have room for decent 8S and balance was very difficult if you could find batteries. I have to say at this point almost every FW 90mm 8S still is difficult to get balance on, proper balance, not where it says in the book .

The V2 has a smaller wing span and is heavier by the published numbers. That means the V2 will probably land faster than the V1 and probably have a higher stall speed.

More power may help overcome some issues caused by higher loading but I expect that higher power will really cause more crashes because more power really has a tendency to get you in trouble when you are stalling. Having airbrakes and reverse thrust will be a bigger plus landing than overall thrust for this plane.

All my opinion of course. And yes, I ordered one first thing yesterday.

For those of you wondering, Wes, our resident test pilot, said that the V1 at full throttle could not keep pace with the V2 at half throttle. That tells me all I need to know about concern for wing load..

Nothing? You mean to tell me that a much higher weight to thrust ratio has nothing to do with wing load? Say 1:1 for instance? I’ve flown high wing loaded jets with awful power systems and the results were predictable. I’ve also flown high wing loaded jets with a terrific powerful setup and it flew like it was light.

You may be technically correct in your comment but please don’t tell me power/thrust doesn’t play into the equation. All due respect of course.

That is NOT what he told you.

His comment is correct (all other things being equal).

That tells me all I need to know about concern for wing load. While this model may be a little heavier than V1, it also carries a new gen powerplant that more than makes up for the wing load factor.

I grabbed the 8S and plan on going nuts with it. LOL.

[Aros]

Yes the gear mounting sections have been strengthened over V1.

[silver182]

The gear itself even on version one was strong. The problem was the plastic mounting box for the gear. It was weak if they strengthen that and they’ve strengthened the gear both main and nose. No, have they done that I don’t know.

[Reptielenfreak]

So im wondering how bump proof the gear is. Motionrc mentioned that on short grass runway it will be fine, but later om he was telling that the land gear bars or struts are there to make it one of the best gears.. so how strong is it against bumpy grass fields

[Evan D]

About 20mph depending on the airframe.

[Aros]

Good question, I am sure someone in the forum can answer. Plenty of stat junkies out there. This is actually going to be my first 8S 90mm EDF Jet. I've always flown 6S. It will be fascinating to see what difference I can tell when the time comes.

[bonehead]

Does anyone seen data re difference in performance between 6S and 8S versions? I am wondering if Freewing or Motion has actually measured speed differences between the two

[Evan D]

Flaperons work great on F-16’s as do tailerons.

Amazing looking jet, love the colors, led's and the airbrake.

I wonder how effective the airbrakes are in compare to flaps?
also how effective are the gear struts i believe they are called for the gear itself or is it more to look scale?
anyway i would love to own one

[Porkster]

Yet another F-16.

Pass!

happy to have it along side the other 8 F-16s I own
from UMX to turbine

[Porkster]

Awesome!! Got mine ordered

[kallend]

Yet another F-16.

Pass!
