A template for flying wings - and a new test tool!

Lockdown! Here in the UK it's been three weeks of relative quiet - and we're only half way through! To make things worse, it's been perfect weather for DLG...

On the bright side, I've been keeping busy with a couple of projects - a new template, and a testing tool for OpenTX setups...

Jumper T16 Pro - is it ready for prime time?

[31 Mar 2020: MPM developers announce support for ACCST V2.1]

The Jumper T16 has been attracting a lot of attention recently - hardly surprising as it's well equipped, runs OpenTx, and is aggressively priced. Droners and sport seem to like it... but is it good enough for high value sailplanes? Could it replace my FrSky X9D Plus?

There was only one way to find out, which was to get one and play with it!

Crow-aware adaptive elevator trim

If you fly advanced sailplanes, you'll almost certainly be using crow brakes. And you'll also know of the difficulty of achieving perfect pitch trim.

In this post I describe an adaptive trim system which makes it easy. The pilot simply uses the elevator trim to correct pitch deviations regardless of crow. The system is based on a Lua script.

A 3D printed CG scale

How do you measure the CG of your model? Very likely, you'll be balancing the model over a pair of pivoting arms, or - if you're feeling lazy - your fingertips. Low cost yes, but not very convenient or accurate. Well you've guessed: there's a better way...

A 3D-printed case for the RX6R

FrSky's latest RX6R receiver is a great little device - except for one problem: it comes with a flimsy cardboard wrapper. That may be okay for a foamie, but for more serious use a proper case is required.

Ahi 1.0: an OpenTx template for aerobatic slopers

I've just added a new setup to my library of soaring templates. It's for 4-channel aerobatic slope soarers like the Ahi, Phase 6, Voltij etc.

Frsky RX6R - a tiny full range 6CH receiver

The FrSky RX6R sounds like the answer to a lot of pilots' prayers - a receiver small enough to fit in a Pitbull or Stribog without looking as if it's been jammed in with a hammer! What's more, the RX6R is claimed to offer 40% more range than X-series receivers. Sounds too good to be true? Let's find out... [note: updated 18 Oct 2018]
