The Vintage Model Company is, like the rest of us, trying to address the current crisis in the availability of good quality balsa wood, and have been slow to reissue the Aerographics kits (including the Flitzer) they acquired in the spring (SAMS Models is, alas, no more) .

I get requests for Flitzer plans (as Howard intimates, it's a splendid flyer) but these I cannot (yet) supply. So, Daniel, when you have finished with the plan you could make a high quality scan (plus the parts of course) for our files?:whistle:

Amazing what you can get done on a rainy sunday. Just awaiting a new airbrush courtesy of Santa.

Now then, in preparation for the xmas break I ordered a Skyleada YF100 just because I like a challenge. Apparently they don't fly as designed, however with Roger and Steve Bages keen eyes and comments on taming this beast, and the recommended mods, I figured why not. I DID NOT expect it to be quite as large as it is and looking at it I wander if it's a TSP L3 candidate? The pic has an L3 laid on plan...any suggestions anyone?

Hi Daniel,

I think it would be overpowered by an L-3 - stick to a TSP L-2 for starters , and work up to a TSP L-2HP if flight tests warrant it.
It is indeed quite large, and draggy, but it is, if built according to the plan, quite light. Remember Richard Crossley's 'Whiff of power' maxim. :unsure:

Hi Daniel,

Mike Stuart made one quite a while back but couldn't get it to fly well I seem to remember, Might be worth contacting him for his comments.

Roger adds:

Andy Blackwell has this to say about this model:

"Mike Stuart F-100 did fly if memory serves correct. :S From memory, it was totally unpredictable if overpowered, knife edging every which way. However, with a 100/120 mN L-2 it would wallow at waist height but in a straight line.

I remember filming it coming toward me then realised I was in the firing line, the machine hitting me full square in the groin :woohoo: . Enough said".

I may move all these F-100 postings to the relevant thread, see:

Skyleada F-100

A shapely little jet I've long been enamoured of is the Aeromacchi 346 (also known as the Yak 130):





I saw it 'doing its stuff 'at the Fairford Airshow in 2018 and was well impressed. As you can see it has a nice Junoesque blended fuselage, difficult to capture in a profile, or even semi profile model.

I have liaised with Rob Smith in the past, and, working quickly as ever, he came up with a draft plan from which we both made mock ups. A 'solution' we arrived at was to move out the lower fuselage to create a facsimile of the Am 346's wide body. This gave somewhere to put the motor. Here is Rob's second mock up:



Rob says it glides quite well, but I wasn't sure if the shape of the motor duct wouldn't cause aerodynamic problems one the model got up to speed. The motor is a Rapier L-2; I thought the model could be a bit bigger to take a TSP L-2. My 'mock up Mk2' is shown below:



As you can see, my 'duct' is 'straight through' and not sculpted, Similar to the old 'X-13' design of many years ago.:



This could fly very nicely indeed.

Rob is busy refining his plan, but we would both relish any thoughts others may have about this model and the design of the lower fuselage. For starters, the front fuselage could be 'fleshed out', getting rid of most of the the forward spline (which also might cause aerodynamic problems),and we could add a moulded canopy which is such a prominent feature of the full size aeroplane.

Or is attempting a profile model of such a shapley aeroplane as this just 'wrong headed? :)
