A 3D-printed case for the RX6R

The FrSky RX6R is a sweet little receiver, however, it comes with a flimsy cardboard wrapper - the first thing I wanted to do was give it a proper case. And the obvious way was to 3D print it.

There was a problem though: I had no prior experience of 3D printing. Which means that this post is not just about the little case, but also about my journey into a fascinating new area.

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]

Adaptable ballast spreadsheets, using array formulae

[updated 30 October 2018] 

F3X pilots love ballast - it makes our models fly faster! The problem is knowing how much to add, and where to put it to achieve a particular CG.

One option is to employ a trial and error approach, with the help of a CG gauge. However this can be very time consuming, especially with complex ballast configurations. It's so much easier - and far more flexible - to use a spreadsheet as the primary method, with a CG gauge to check the results.

Photo magic at the Welsh Open

Here's a publicity shot by MKS, using two of my images. It shows Joel West winning the recent Welsh Open. I think their graphic designer has done a rather nice job!

A One Minute Guide to F3F

F3F is the Formula 1 of slope soaring, but you don't need a Ferrari to compete - just a moulded glider, a transmitter... and a liking for ripping up the slope!

RTGmodel Stribog review

At the end of 2017 I decided to look around for a new F3F machine for the 2018 competition season. After hearing good things about the Stribog I placed an order, and nine weeks later a huge box arrived at the door.

Fast forward... the Stribog has been assembled, tested, and flown [and won!] in competition. Has it replaced the Needle 115 as my number one model? Read on!
