Looking to move into a new EDF

I did not realize how small the rebel was. My eyes have a hard time seeing stuff under 1100mm

I too was worried about that before flying it but after flying it, it really was okay. I didn't lose orientation once and I got a pretty good distance out. I can't tell you why because I hadn't realized it until I saw your post.

Oh! I just thought of why maybe.... They may be short wings but they are kind of wide. That and the fuselage is very long?

[AkumaZeto]

I have had terrible luck with planes this small. Wing loading couple with small size

I've been lusting for the Freewing 90mm F-15 since it came out, but I would have a problem transporting it. So, I ordered the FMS 64mm F-15, mostly on the great reviews it has gotten. Since the Eagle was nearly my whole career at McDonnel-Douglas, I just had to have one.

no experience here with the f86 or 262 I guess

I've got plenty of flight time on the F-86, but nothing on the 262.

How tight can the Saber turn? Edfs in general need wide turns correct? Cant exactly bank and yank

Turns really aren't all that different from flying a warbird. Same basic guidelines, just don't bank and pull full elevator immediatly. If you keep your flying even somewhat scale, this won't be an issue.

where is a good place to get lipos for it. I know motion rc has them but at 75-100 a pop thats a ton and I would likely only get one lol

In my experience, I don't see much difference with the circumference of the initial turn-in, when you account for speed differences (EDFs being typically faster).

However, you can only make a handful of tight turns, etc. then you start to lose control authority as you've burned your stored energy (speed or altitude) and there's no prop wash over the control surfaces so they lose effectiveness.

Practically, EDFs get mushy on the controls sooner and need more control throw as a result and in my experience (in stock form, except for ailerons given the typical swept wing configs.)

A typical stock EDF will eventually stall whereas an (overpowered) prop plane like some warbirds can turn tightly indefinitely by hanging on the prop thrust.

Most EDFs are harder to get to 1.5 to 1 thrust to weight or higher, where it'd be a more accurate comparison though too, but you'd still have the thrust coming from the opposite end.

[AkumaZeto]

so basically you need to carry lots of speed to retain authority over the surfaces. To many turns equals slower momentum equals stall. I was asking because if turns need to be generally wider than I will need to find a new space to fly. I am a AMA flyer but my local club is all snobs and they make me feel bad when I go there because of the foam. So I am left to fly on dead end roads or football fields. It really is demoralizing.

Try this:

Play race with an EDF model and a roughly 2/3 of equal watts and equal weight conventional prop model. (it takes 50% more watts with EDF to get the same performance as conventional prop)

Have the first run making turns as tight as the prop plane would normally make laps.
Then another run with double the radius turns.

You will note that the prop plane eats the EDF for lunch first run.
Second run its a real race.

That's a shame....

Dang man! That's exactly why I haven't gone ama yet. Always a few douchebags at the field. I like "fun flyers" myself, even if the field isn't perfect.(I am, at least, FAA registered.) Ron

[Flygirl]

I'm AMA and FAA but don't fly at an AMA field. Like CZ Flyer, I want fun people who aren't crabby about whether you have foam planes, quadcopters, or like FPV. We have been auditioning local AMA clubs but so far we like flying by ourselves. Going to try a new one out this weekend though I hope. See what they are like...

[AkumaZeto]

I went AMA for the inserurance as a PARK FLYER. I wanted to cover my ass in the event something happened. I decided to pickup the sabre and the 262

Turns are a bit wider, yes, due to higher speeds. My point was generally though that you're able to make one tight turn with EDFs without burning up too much energy to risk a stall, provided you're up to speed beforehand. EDFs take longer to accelerate than a prop. Turns aren't the same radii as a prop. driven plane, but it's not hugely different in my opinion (at least with the two EDFs I fly) but my prop driven planes are faster than average also (70 - 90 mph).

However, regardless of your space you could fly in a very limited area if you concentrated on the vertical plane. For instance, instead of horizontal turns use Cuban 8's or split S's to change direction. EDFs have more limited vertical due to the lower power to weight ratios, but in this way you generally have unlimited space vertically (if you have sufficient speed or thrust) unless your field has a vertical height restriction.

If you have a limited flying space EDFs could be a challenge. Gradual turns are necessary at slower speeds for certain and more so than others with some airframes.

Two! Both! Gonna be a fun summer!

Sorry to hear that. I have had similar situations with Helis at clubs and ended up flying at a park. However, I must say that sometimes persistence can be a good thing trying to fly at a club that believes only balsa/gas airplanes are "real" RC planes. My local club here in MN was that way when I first started going there. I kept hearing "its just a foamy" and other similar comments. However, a lot changed when I started bringing FMS warbirds. They started to realize that the "cheap foamy" was more detailed, more scale, and flew better than many of their big balsa gassers. If they nagged on me about having a foam plane, I nagged on them about having a 2 blade prop and fixed tailwheel on their big gasser P-51. Four years later about half the club is flying foam electrics now. So, don't be quick to give up. The "I only fly balsa/gas" types aren't going to be able to hang on to that idea forever..
