70 mm Freewing F-16 Maiden Flight On 4S Power - Also Compared With 6S Stock Version - Horrible wind
Maiden flight of my new Freewing 70 mm F-16. I bought the version without a motor and fan so I made my own and added a QX 3500 kv motor to fly on 4S 2800 mah. Weight is 1705 g, so 100 g less than specifications for the 4S version.
I also modified the nose retract and lowered the retract in order to dig out foam from the intake area to increase airflow.
I maidened with CG at 100 mm with gear down (90 mm in manual but my friend flies at ~110 mm) and it still needed a significant amount of up elevator trim.
The wind was horribly choppy so the light F-16 was thrown around, and when I tried to land it was being bumped up and down a lot so it was hard to get it to touch down softly.
The maiden flight with my 1:32 scale Simple Hercules design. It's extremely lightweight so it didn't like the strong gusty conditions but it flew very nicely other than that. It's capable of slow flight and sounds really realistic because of the slow high pitch props.
The maiden was performed with a 3S 3000 mAh battery for extra weight since it was windy. It will fly fine with a 2S or 3S 1000 mAh battery as it needs very little power.
Wingspan: 1290 mm
Length: 910 mm
AUW: 980 g (with 3S 3000 mAh lipo)

I wanted this back in the day when I was a kid. It's an original Kyosho Ferrari F40 (Kit No. 4257) that I bought partially built from someone on Ebay. I finished it and painted the body with Tamiya PS-2 paint. It runs great and looks fantastic. This is closer to 1:8,5 scale than the specified 1:10 scale, and it has much more presense than the usual 1:10 touring car size. It is about the same scale as my Porsche 959 rally car.
The stock tires are cracked and only good for display, so I left them on the stock wheels and 3D printed accurate replica wheels to use with running tires. The modern tires were made for 2,2" and since this car uses the old 2,0" standard I had to modify the modern tires to fit by cutting off a segment and gluing it back together. It works fine and I posted some pictures of the process in my community tab here on Youtube. You can find the 3D printable replacement wheels here:

Slotcars are boring so I wanted to make something fun that works in the same space as a slot car track, but with RC cars.
I modifed two WLToys K989 for a tiny turning circle and slower speed. I used motors with a speed of 9000 rpm @12V to make the cars much slower and easier to drive for inexperienced drivers and will make the buildable track from training mats this winter. I might go with slightly faster motors if it ends up being too slow to be fun. There are many varations of 130 motors to choose from. The stock motor is ridiculously fast. I might make nicer looking wheels that suit the models better, though they aren't super scale. They are very durable though.
The white car is a Ford GT40 MKI and the red car is a Ferrari 250 LM. The bodyshells are from Team Bluegroove.

Test flying a scale three bladed Eurocopter Starflex rotorhead.
The blades are 580 mm long with a chord of 42 mm. They are semi symmetrical and have 3° of twist. they weigh 67 g each and are made from oak.
The scale main rotor head and the scale tail rotor is made from 6061-T6 and 6082-T6 aluminium.
This is my test helicopter. It's a Century Swift 16 which has been stretched with Swift 620 parts. It has a Hacker outrunner and 8S 4270 mAh lipos.

I altered the angle of the hips slightly in CAD before printing. He can also be changed using a heat gun carefully.
The figure weighs 89 g and is approximately 375 mm long.

A fully 3D printable helicopter. Everything is printed except for the mast (3mm carbon fiber rod), ball bearings, screws and electronics.
It's currently fixed pitch. I have made and flown both flybared and flybarless versions of the head. It flies flybarless with an Orange FASST receiver with integrated 3-axis gyros.
I have designed most of the parts for a CCPM collective pitch version but haven't printed it yet.
I'm making a body for it now. I'll upload it to Thingiverse soon.

Innekjøring på den lokale skolen i regi av Målselv RC
Jeg kjører først 3D-printet Toyota MR2 med 3D-printede driftedekk, så en Tamiya M-05 VW buss og deretter en 3D-printet "M-chassis"-størrelse bil med fremhjulstrekk og Alfa Romeo-karosseri.
Indoor driving at a local school. Driving my 3D-printed Toyota MR2 with TPU drift tires, then my Tamiya M-05 VW bus and lastly my FWD "M-chassis" Alfa Romeo with a silvercan Tamiya 27T motor. The black car I'm battling with at the end is a Tamiya M-chassis with a Torque Tuned motor and a better driver than me. He lapped med before.
