Test flight reports of new aircraft

 

NEW AIRCRAFT TAKE TO THE SKIES :-

Its quite unusual to have 1 new aircraft to report on this late in the flying season, but to have 3 in such a short space of time is amazing!!

The latest creation is an ‘Archie’ scratch built by Chris Wilkinson; older members will recognise the aircraft as it was quite popular ‘back in the day’, with the late John Stewart’s versions still in existence today. I’ll hand over to Chris now so he can explain a little more about his model –

“I’ve been looking for a build project for a long while now and always been a fan of the early 70s β€œArchie”
Having seen a couple of them returned to flight recently I duly searched the internet and found a plan which I downloaded and printed out on several sheets of A4 and taped them together.
She has a 48” wingspan built from balsa and plywood and covered in Fokker Red Oratex covering with Aerokote semi matt to fuelproof the ply panels.
Power comes from an OS .46AX2 and 11×6 prop giving power to spare.
Radio gear is Futaba 617receiver with 3 standard servos in the fuz and 2 micro servos for the ailerons.
Having test flown her today (Saturday) in reasonably blustery conditions I was pleased with how she handled with only slight down trim required for straight and level flight.
Flying her brought back fond memories of our great friend and fellow modeller John Stewart who I remember flying his and was my inspiration for building this model.
Look out you British there is a new ‘Hun’ in the sun waiting to even the score!!!Β  “

By pure co-incidence, Chris Bougourd and I chose the same afternoon just recently, to undertake test flights with our latest acquisitions, following very poor weather recently, a lull in the wind strength and a bit of sun got us both down to the flying site with our aircraft. Here is a brief overview of the proceedings –

First off is Chris’s aircraft which was acquired by him from former club member who had only flown it a couple of times previously. Chris installed new avionics throughout and the resulting test flight showed that Chris had got himself a really great aircraft and one that will give him many happy hours exploring its aerobatic capabilities. Details are a little sparse, but Chris tells me it is an ‘Exteme Flight’ Extra 300 with a DA 60 motor providing the urge (and boy does it have some urge !!!). I believe the wingspan to be 85″, which gives the model real ‘presence’ when airborne.

Here are some photos I took that afternoon of the maiden flight-

The next aircraft which saw air under its wheels for the first time, was a model that was built by the late John Ogier. Following John’s untimely passing, I decided to purchase the model from his effects and fly it in his memory.

A year on from that decision, I finally got my act together and fitted out the ‘Spiteful’ with the hope of doing John proud by getting the model successfully airborne. I am pleased, honoured and relieved all at once that my hopes for the model have been realised and that she flew really beautifully… everything you’d expect from one of John’s creations.

The model is of the proposed successor to the Spitfire, very few were actually made and the end of WW2 meant that the aircraft’s development was no longer required. The full size has quite an interesting history, and I’d definitely recommend a quick Google search to read more about this interesting aircraft.

The model is all built up construction and is of course very light, just like all of John’s creations. AUW is a tad under 6lbs (including 6ozs of lead for balance purposes) wingspan is 65″ and a 4 cell lipo drives an Overlander 35/48 motor and 11×8″ wooden prop. Initial flight time was 4 minutes and showed 54% battery capacity on landing.

I had long mulled over where the CofG was meant to be, as John’s plan didn’t show one (very unusual given’s John’s meticulous attention to detail), but after scouring the web, I found a very small pdf of a glider version which showed the Cof G. After a bit of ‘finger in the wind’ calculation, I arrived at what I hoped would be the right location. In the event, the take off was quite brisk and only 3 clicks of down trim were needed for straight & level flight.. a fitting testament to John’s attention to making straight & true airframes/wings and a huge sigh of relief from me that the balance point was just about right πŸ™‚

I am indebted to Mike Burton who acted as my wingman on the maiden flight, but unfortunately as both of use were busy during the flight, no airborne photos are available as yet, however there are some ground based ones which I hope do credit to John’s creation.

Apologies for the lack of a decent spinner, I decided to test fly without one so as to see how hot the motor etc got; pleased to note things were quite cool, so a ‘proper’ spinner will be used in future.
