Any chance you could share the needle cutting files?So in December I ordered a 50mm EDF for this plane from Banggood, finally got it, seems I ordered the 3s version... will it still work? Edit* Found the spec, apparently 650grams, should be ok.
Also have the parts for a TimSav needle cutter coming and on the Facebook group somebody shared the G-code files for this plane.
What size battery? On my eflite f-16 I get 3:30 flight time on a 2200 4s.is a 2:20 min flight typical?
Yup that’s around what I get.is a 2:20 min flight typical?
Did you start/finish your needlecutter?Any chance you could share the needle cutting files?
Yeah that should be enough, build very light and use a high C battery and it should feel the same as a 4s powered plane.

Awesome, thanks!Should be attached. I haven't got my needle cutter yet so I have no idea if they're good files.
The replacement aurduio arrived from china (finally) but neither me nor my buddy have had the time to install it. Hopefully between the two of us we can get it figured out over spring break...Did you start/finish your needlecutter?
mine was a 1,300 mAh 3s. Sounds like I need to dial in the controls so I can just Fly! time to get more 1300mAh 3S batteries. has anyone tries to melt a bottle to make a canopy using the Foam version as a Buck? (I've never made a heat-molded canopy. This model seems worth a try.What size battery? On my eflite f-16 I get 3:30 flight time on a 2200 4s.

Finally got a maiden in, right into the ground. I've got the battery mounted as far back as I can and it's still pretty nose heavy. It felt like it's either too nose heavy, or just didn't have enough power to get going. Threw it pretty quick to start, looks like I'm rebuilding the nose and reevaulating where all of the electronics are going to sit for the next round.
Use a turnigy 1300mAh 4s (https://hobbyking.com/en_us/turnigy-nano-tech-1300mah-4s-45-90c-lipo-pack.html), did not measure thrust before hand. I'll have to get out the 'ole water jug and harness before I try it again to ballpark the thrust. Running out another set of plans now...
I’m sorry to hear that. It sounds like it’s either too nose heavy or not a strong enough launch as you were saying. Where is your Cg currently?Finally got a maiden in, right into the ground.

I've gone as low as 0.58 for runways. As long as the thrust-to-weight ratio is greater than the inverse of the glide ratio (drag-to-lift ratio), it'll be able to fly - the only constraint then is the length of the runway - some IRL jets get away with TWRs less than 0.2! When acceleration to flight speed with an initial launch speed of below stall speed is needed, high TWR is the way to go.That's not very good.. but don't give up, never give up
what battery did you use? Measuring thrust (with the battery you're planning on using) before maiden-ing may also help.
Members (I don't remember their names, sorry) suggest 1:1 AUW thrust ratio for hand launching. And if you add landing gears and have long enough runway for take off, around 0.6 ration should work too (again, I haven't tested this numbers myself.. but something I would consider for EDF jets)
