That looks great!! I don't know now I missed your video You really pulled a rabbit out of the Hat with that abort Maybe with a light build I can get away with 5s lipo and make life easier for the stock fan , I'm not looking to tear up the sky . Thanks

Anyone have an idea of who has a decent price these days on a Fly-Fly EPS F-100?

Has anyone used the Eflite electric retracts? Thanks!

Eddie I have been using the E-flt. retracts for about 10 flights now with excellent results. Way better than the Fly Fly units. Beak

Hey Chief, will you snap a pic of the underside of your jet with the eflite retract setup? I am thinking about swapping mine out.

Hey Wingspan, I looked at your site and the "Buy Now" link shows the shop is not authorized to receive money?

Beak, thanks - the 10-15 size retracts are strong enough? Are you using larger wire, or by chance struts?

I was thinking about this project mostly in the context of glassing the airframe. So I'd be going with EPS foam and then most likely a 2200 watt system. So I'm guessing at least 7 pounds for the ready to fly airplane.

I have the "10-15" size on a 8pd EPP scratch build and they hold up just fine. Also you can drill the strut holder hole for larger diameter struts if need be. The practical difference I see in some of the PZ e-tracts (PZ-15091 e-tracts) is some have the bar lock the strut holder in open position and some have the strut holder resting against the metal bar in open position.

Does glassing the frame make it more crash resistant or is it mainly for looks?

Thanks for your thoughts on the landing gear!

Purely for looks and in flight airframe rigidity (flight qualities being a little more crisp).

If someone wants to prep for a crash, the EPO is a better solution as it's more durable and a little spongy.

You will have to do some minor mods to the wing and forword fuse to make them fit. I even used the included struts. You will have to shorten the mains (easily done with a lathe) as much as you can. Take a look at my video a few pages back in this thread.

I can post some pictures and provide some measurements for the strut mod if anyone needs. I also have a set of Lander Mig 15 struts that will work on the FF F100 if anyone is interested in buying them. They would be more scale looking than the EPF struts but not as strong

McGoughman-
I notice your struts are a little different than the ones Jepe are using:

http://www.jepe.org/indek.htm
(click on "landing gear" on left side column)

The Jepe site shows EPF gear and struts almost exactly the same as Hobby King sell, but the struts do not have the offset fork assembly. This makes it possible to fit the dual nose wheels with a little bit of drilling - as well as the lager main wheels. Does anyone know if HobbyKing also sells the non forked version of the strut (I could not find it on their site but their site is huge and I might have missed it), or does anyone know where to get the different struts? I have an email in to Jepe, but I keep getting a bounce back as undeliverable: So if anyone knows where to get the F-100 style struts that Jepe seem to have on their F-4 using the basic EPF "Titan" gear set, (or a functioning Jepe email address) - please do tell

Got my F-100 last week (thx for fast follow up Wingspan) and it's definitely one of the biggest EDF's I own now. It's as long as my DC-10 scratch build (thank goodness the wings detach) and it's sold me on not buying any more EPS foamies cause the durability of the EPO is notable right away.

Question, what are final build weights folk are getting less batteries and the stock landing gear?

For a 5+ foot long EPO foamie it's fairly light which will make for some great scale flying but I'm more concerned about 10+ mph wind days now, any slow flying of my 8pd DC-10 gets it pushed around a lot.

TIA

Give me a day or two Boomer. The mains were almost a drop fit, the nose had to be recessed. I made a plate for that and mounted the steering servo right along side.

Got 4lbs 4oz from stock fan and rotor using 4s\40c\4400 70amps and ChangeSun 90mm lip....

Will this be enough thrust and authority or is 5lbs minimum?

Don't want to go fast but want the thrust when I need it.

TIA,

Did your stock fan unit come with a 6 or 7 blade fan? I ask because
the 7 blade fan is the same as the original FlyFy rotor and they were
never balanced, so if you got the 7 blade be sure to balance it before
you fly your F-100. If it's the 6 blade rotor, I believe that they come
balanced, but to be sure you better check it out.

The thrust you are getting seems adequate, but what is your flying
weight, total watts & amps at WOT? 1:1 thrust vs. weight is always
good.
