Roger,

Yes, the motor on the original plan was angled down slightly so that the efflux didn't impinge (much) on the trough. After seeing how well the 'deflector trough' worked I tried a deflector vane glued into the P1121 trough and it worked well (but tended to eventually fall off). On the later version of the plan I added this deflector.

A better solution would be to mount to motor tube horizontal and have the trough also run horizontal before 'kicking down' ar the rear. The trough does get a harder time and needs re-lining with aluminium once in a while but it's worth it.

Alan Trinder has just sent me a cracking photo of his Viggen, built from a kit that I'd rejected (you will remember I was having printer problems). The model was originally destined for Piotr Tendera) but I sent to Alan instead with a (large) batch of motors :



Alan writes:
"I thought you might like to know the Viggen is complete and awaiting permission from HMG to be taken out for its first flight.
I found it difficult to believe the kit wasn't up to standard. It seemed fine to me (especially being someone who grew up with so-called model kits in the 1940's) and I really enjoyed building it.
Would you recommend fitting a thrust deflector before the first powered flight?"
:lol:

I'm glad us modellers are keeping busy in these very strange times. And I' m pleased we can build models in the knowledge we have something to power them with. I sent Rodger Wright a batch of motors earlier this year for his just completed Sukhoi Su 11



Again, a very nice job. I particularly like the different shades/textures of the 'natural aluminium' finish. Rodger says 'he has plenty to learn' - it was his first foray into 'plunge moulding' a canopy - but it looks fine to me!

Onward and upwards! :cheer:

Super job, silver is notorious for showing all the tiny blemishes and this looks pretty good to me. I like the way the silver has been varied with airbrushing presumably, Very nice, I did see one fly once but it badly needed a down thrust tab/deflector, as it climbed up steeply then dived down steeply, oops.:unsure:

Note added by Roger: the flight pattern of this Richard Crossley design can spectacular. It climbs steeply (it was best with a Rapier L-2 HP) and then turns to kill the stall. I seem to remember Chris Strachan launched by catapult. The model comes down quickly when the power stops ('climbs like a rocket, glides like a bucket'). This was useful at Old Warden on a windy day as it kept it in the field! :lol:



Above: Chris Strachan contemplates his Sukhoi Su-11 prototype. An iconic image of our hobby, I'm sure you will agree!
