Flightdesign, have you looked at fluttering of the wing yet?
It took 3 different designs to stop the fluttering at full throttle for my F-14. How is the wing joined with the swing arm?
I'm with you @Captain Jay. That F-5 has always been my favorite fighter jet just based on style alone. It's the most slippery, streamlined, sleek & sexy looking jet ever in my opinion. Most Beautiful Bird!I'll dummy something together. That's what I do... wether it flys or not is another story. Half the fun is building and designing off the cuff for me. I'm thinking of using my 2 x 64mm for an Northrop F5... love this jet!!
That is impressive. And you are a fast builder!!Wingbox is finished, ended up at 160 grams and seems to be extremely sturdy. Wingspan 138 cm extended and 81 cm swept. Had some major difficulties with the left winbox cover fitting, still didn't figure out why. I have made a whole list of "bugs" that the v1 plans has that has to be fixed, some them were expected others were not. all the seams on the nose are clearly visible for two reasons, first of which is that I suck at master series building and secondly the foam I'm using has a thick cardboard. Now Lets hope this thing flies when finished...
Very, very impressive. Just to design the thing, then make it real with such a clean build. It BETTER fly. Dude, you are one of them there Master Builders for sure!Wingbox is finished, ended up at 160 grams...

Well that sucked... literally. I checked the edf wattage on full throttle and it literally sucked the reciver into it from the small esc cooling hole. I checked at least two times that the intake is clear but of course I forgot about that small hole... I feel stupid now. Shit happens. Thats how you burn money in like few milliseconds. This is definitely not the end of this tomcat project, it just takes a bit longer now. I will continue building, I can replace the edf from below where I removed it. The reciver is fine btw, the hard case saved it.
That's pretty awesome!!! Nice flight!!Tomcat is back!
The F-14 Tomcat v1 is finally finished. I have now 2 successful flights on the tomcat with the wings fixed at 20 degrees sweep. The first attempt was a failed launch, I thought it was a smart idea to toss it holding from one of the engine housings, far away from the mid line of the plane. Well, it made a flip and dived into the ground. I had to rebuild the nose, not a big deal. I also added a point under the fuselage to grab on for tossing. The second attempt was a huge success. The tomcat performed beautifully in the air, but that flight was not recorded. The third flight was pretty much as successful as the first one and there is a video also.
Here are some numbers for the F-14:
Length: 1260 mm (scale 1:15)
Wingspan: on 20-68 deg. sweep: 820-1350 mm (Sweep mechanism does not exist yet)
Weight: 1900 g
Static thrust: 1900g at 90A
My stuff:
Edf: 2x fms 11 blade 64mm
esc: 2x 60A skywalker
External bec for the receiver and servos
Batteries for edf 2x 4s 1550mah 100-120C
Batteries for receiver and servos: 2x 2s 350mah
2x sg90 servo for the stabs
Such a beautiful job.Tomcat is back!

Going to attempt flying with wings fixed at about 50 degrees next, hopefully soon. Slighlty worried about the takeoff, with wings swept it needs more speed to be stable and also the moment of inertia is smaller which makes it roll easier. No room for a bad tossAny more flights?
Yea working on it too, having some difficulties to make all the curves look nice and be easy and repeatable to build.I think he is working on finishing the Mirage 2000 we collaborated on. Watch for that build thread next...
