        Nice flying John! That last landing approach was perfect.

          Thanks! Yeah, it was nice, I am thankful for the plastic coated rails on the wingtips, haha, I look forward to getting the LG fixed and redeem myself!

          • F-16v2, number 2 model.
            It's coming along nicely, I have been busy with work and haven't had a chance to finish setting it up but, I did manage to install and test-run the new motor with XRP 12b fan I ordered from Turbine RC (France).
            I decided to give another try on 4s with the following equipment installed so far:

            XRP 12b 70mm fan
            Model: Model CHS-70-12PV2
            Link: https://www.turbines-rc.com/en/chang...17-et-4mm.html

            Leopard 3400kv
            Model: Model LEO-2860/3400
            Link: https://www.turbines-rc.com/en/28mm-...0kv-motor.html

            ZTW Gecko 85A ESC
            Sku: ZTW4085201
            Link: https://www.motionrc.com/products/zt...c-with-8a-sbec
            (ESC programmed to 15* timing and 15% power start all else is default)

            The results are on 4s Admiral Pro 60C 5000 at 3.8 per cell (it wasn't fully charged) are:
            At 100% Throttle it would draw around 92amps. (the ESC rated at 140A max for 10sec)
            Also read out was showing about 1200+Watts at full throttle. (Will post exact numbers later)
            And I have no way of testing the thrust... sadly.
            At about 70% to 80% throttle, the reading for Amps was showing at about 65 to 75 amps and about 700 to 800watts but, it did jump to 90+ amps at full.

            I still want to try this in FPV and will work on the canopy and cockpit probably next week, will do same set up as I did with the first one. I will post all pics for the build, maybe a video. I also moved ESC under the vertical stabilizer and will cut air intakes just like I did with the first model. So, basically the new location for the ESC is not in front of the fan but, right under the tail, and rests on that wooden plate instead of being screwed under it as intended by design. I still need to work out a way to pull that fan out and service it if i have to, with vert. stab being glued it's not going to be easy and short motor leads don't help at all. However, I am not too worried about ESC being "incased" permanently under vert. stab. It should last a long time, i am very happy with ZTW ESCs.
            By the way, the XRP fan barely fit in the fan housing. I'll explain later in the video. Also, I had to "shave off" the fan foam cover (at the bottom of the fuselage) in order for it to fit snug over the fan.

            I think that's about it for now.

              I was running 4s 5000 Admiral Pro 60C on 2850KV motor and it felt significantly under powered, plus adding fpv equipment to the total weight of the plane.
              Dont get me wrong though, I think 4s with 2850kv motor will do just fine for a new EDF pilot... just can't add any more weight to it lol. I had few close calls on my first flights, watching my brand new plane barely clear the tree line and slowly gaining altitude.

              So, i am definitely getting another one for sure and was thinking about following setup i can experiment with, please let me know what you think
              1. go with 6s 5000 and 2300kv motor. Will it gain performance with 6s 5000 Admiral, or will it be heavy and i will end up having same issues as i did with 4s?
              or
              2. go with 4s but, use something like 3000 to 3500kv motor... Will have to get 100+Amp ESC but, i think it might just give a bit more thrust than the "stock" 4s 2850kv motor.

              What do you guys think?
              I fly mine with a heavy pack. That is all I fly it on. 4000 were ok but the plane really came to life when I added a bigger pack. I ran Roaring Top 6s 35c 5800 for almost 2 years and just recently switched to the 6s 50c 6200mah Hobby Star packs. The plane flies really well with these packs too! I flew it stock for a while with the bigger packs but once I upgraded the power it was even more of a no brainer. It is all I fly with now!! Just a couple clicks of trim and then adding more elevator throw is all that is needed. I still get lots of high alpha and near unlimited vertical with the plane and my current config. Here is a video from last weekend...


              I have way too many planes to list off... But I love to fly them all! the 80-90mm Jets are my newest addiction! Also check out my youtube channel for TONS of flying footage. https://www.youtube.com/user/gooniac33

              • Here is the followup vid to my earlier post about Leopard 3400kv motor in combo with 12 blade XRP ducted fan unit.
                Had to make minor tweaks to the bottom intake. Now it is held by 4 screws instead of being glued on. That's due to XRP and motor in combination being too long and i had trouble installing them.
                I still need to fly it and see how it handles.
                I have no way of measuring thrust at this time and i don't have exact RPMs of the fan.
                FYI This is just an experiment with 4s.

                Gooniac33, what motor and fan are you running on 6s?

                Thanks!
