    Just purchased my own Avanti S and I’m extremely excited to say the least. My question is, what are your favorite mods to do? I’d like to get pilots, paint the cockpit, etc.
    Congrats! This is an excellent flying plane. You’ve received some great suggestions above. Below are some of my thoughts as well.

    Before the maiden, complete your typical pre-flight checks like ensuring all screws and metal components are secure, ensure no components are missing from aircraft assembly, ensure hinging is secure, check all linkages for security, check all plastic-to-foam glue mounts/joints, calibrate your throttle, range check and failsafe check, get your nose steering traveling straight, ensure all control surfaces are traveling in the correct direction and moving freely, check CG, ensure all wiring is seated properly, no electronics are loose in the compartment, battery is secured, etc.

    In addition to the regular checks above, adding some glue (I prefer hot glue for this in particular) to each mounting tabs and end of the spring on each nose gear door. This locks the spring into its proper place (you would want to have the aircraft on a stand inverted and place the spring in the proper spot prior to gluing). This prevents the spring from rotating around out of its ideal position, and when in the proper place the nose doors close and open more reliably and more evenly. The picture below shows it best.

    I didn’t like the positioning and space to place my receiver and any telemetry equipment, gyro, etc., so I made a simple RX/Gyro tray for the Avanti that can be 3D printed, and is available on Thingiverse in the link below.

    After many flights on the Freewing Avanti S 80mm EDF jet, the following below are the throws, expo, and CG I settled on.

    CG: 115mm measured inverted with gear extended. My elevators are level for cruise flight at this CG, so no noticeable up or down trim was required.

    Throws & Expo:
    Aileron (measured inboard) - 14mm Low, 18mm Mid, 22mm High. 20% Expo on each
    Elevator (measured inboard) - 14mm Low, 18mm Mid, 22mm High. 20% Expo on each
    Rudder (measured at the bottom) - 25mm Low, 30mm Mid, 35mm High. 20% Expo on each
    Flaps (measured inboard) - 10 degrees Takeoff, 45 degrees Landing

    • Thanks for all of the great suggestions! It got here yesterday and I got it all put together and setup. I'm very excited to fly it and its looking like tomorrow morning will be nice. I think I will be bringing my A-10 and Avanti for its maiden flight. Any tips for this jet on maiden? Seems like most everybody has had a very positive experience. Is there a "landmark" per say on the jet that would indicate CG? Flying on a 6s 4000 pack to start.

        Just some thoughts on your maiden: It doesn't really need flaps on take-off and I think you get a nice smooth lift off without them. This jet is fast, but flies very nicely at 50% throttle. I only use full throttle on take-off and climbing for a loop/cuban 8/spit S, etc. and even then at the top the throttle is cut way back. It even knife edges at 75-80% throttle, so unless your have a "need for speed", it flies well at a lower throttle. It easily gets into a slow high alpha inflight, use flaps or don't use them, and stalls only at a crawling speed, so try it out to get accustomed to what it does when it does stall (dips a wing left but corrects easily). On landing, you need to land on the mains with the nose up (as does the A-10, which is very important for that one) and it floats very well, so you'll need to bleed some speed off and drop the throttle to a hum. If you maiden the A-10, it too floats in and once you are about 2 feet off the ground, you can cut the throttle, float in and raise the nose. These 2 a some of the few EDF's that can land with the throttle cut. Regarding CG, I fly mine about 5-7 mm behind the manual CG and use a RT 6250 pushed all the way back even under the foam. With that battery, I get about 5 minutes of flight time, so if you are using a 4000, you'll probably get around 3:30, although with the lighter weight than mine, it will be faster, float more on landing and you'll also be able to manage the throttle/time better. Good Luck and let us know how it goes. I think you'll find the Avanti a great flying EDF and it is IMO the easiest EDF I have to fly and land, and you'll also find that the A-10 is also about the easiest EDF to fly/land.

        • Thanks man! My EFlite A-10 is a seasoned veteran of mine. One of my favorite airplanes I’ve ever owned and I expect the Avanti to be up on that list as well. One of the things I was looking for in my next jet was a wide flight envelope, which I think the Avanti fits that bill perfectly. I am very excited to get it up in the air.

            Well the Avanti should fit the bill of a very wide flight envelope. It knife edges great, goes into a very stable slow high alpha cruise, climbs like a rocket, flat spins, rotates, climbs inverted and even climbs in knife edge, etc., anything you can think of and probably a bunch of stuff I can't think of. Enjoy brother, the Avanti (and FW 80 mm A-10 and Stinger 90 of the EDF's I have) all have a "pucker factor" of zero!!! My F-4 is down to 2, the F-16 and F-18 are at 2 1/2 and that heavy dog SU-30 is still around 5, just can't get 100% consistent on the landing with that thing. When I want to relax and go wild, it's time to put the Avanti back up.

            • Maiden could not have gone better. I can already tell this is going to become my go to jet. It just handles like it’s on rails and I was very impressed with how slow it can land. A+ airplane!

                Congratulations! It gets even more fun over time. Ha-ha
