6S Foamboard Radjet Speed Run!! – Not What I Expected....

Today I’m taking my foamboard Radjet out for its very first 6S speed run. Built from Dollar Tree Adams Readi-Board, reinforced with an 8mm carbon fiber spar, and wrapped in packing tape for strength, this scratch build is all about pushing speed and performance. I’m not a professional pilot and haven’t been flying for very long, so this is as much a learning experience as it is a test of speed.

For power, I’m running a PowerDrive 3536 1800KV motor (linking to the FMS 1750KV equivalent) with an APC 7x8 prop, a CNHL 6S LiPo battery, and an 80A ESC. Control is handled by a Flysky FS-iA6B 6-channel receiver with PPM/iBus output. The setup had me expecting serious speed — but the results… weren’t quite what I imagined.

Watch as I take it full throttle, see the GPS speed reading, and try to figure out why it wasn’t as fast as I thought it was going to be. Was it the setup, the conditions, or something else entirely? Stick around — the next flight might surprise you!
