So, in my attempts to develop 3D printed planes I've decided it was time to go back to basics and get up to speed with something relatively easy to trim. This led me to Sharkey and, as I'm using Tendera L2s this has now led to Sharkey 130%

I have had three reasonably successful flights with this. With an 18" wingspan it's a much more comfortable fit with the L2 than was Sharkey V1 which has a wingspan around 13 inches. However, today I've managed to loose Sharkey 130%! She didn't fly out of sight but she did get into a rather nasty corner of my newly discovered flying field which has an electrified railway line, an embankment, a stream and several trees. I decided it was easier to make another model.

I think Sharkey could even be made larger and the L2 would still cope. However, I cannot make my 3D printed scale planes any larger (without buying another printer), and the indications are that I need to. Instead I've got some Tendera L1s on order. We'll see how they go with the existing 3D printed models. Perhaps they'll need to be a little smaller.

I was interested to read this thread as I have owned a 3D printer for a few years now, and whilst it has been great for making various components, the weight had put me off the idea of printing an entire model - I had not heard of LW PLA before. I will follow this thread with interest!
I was also amused to see the foam chuck glider jets - I picked one of these up at Weston Park some years back, thinking about an r/c pusher - which worked out rather better than I had hoped, see the video. The air museum where I work got some in for the shop, and I have a couple of damaged ones to play with...

An outstanding video! I will forgive this first offence of both R/C and a pusher on the forum .... :whistle:

But back to 'Jetex' and away from the 'Dark Side', Andre Bird experimented with these really rather nice foam chuckies couple of years ago. His F-18 F-18 had two Rapier L-2 motors mounted on the top. Andre said it flew well. :woohoo:

His F-15 and F-22 were rather more sophisticated:



All they need is a bit of rubbing down, a couple of coats of paint and proper livery. The new TSP L-2L motors should suit these large models well.

An interesting winter project. :dry:

Just don't make it any worse by turning up with an undecorated profile model.

I have finally found the photos of Andre Bird's F-22 Raptor. I took these at Old Warden in 2016. Andre assured me that it did fly; the photos of the motor instillation show that the moulded foam plastic needs to be well insulated from motor exhaust:





as you can see, Andre was using a Rapier L-3 - the import being that this is quite a large and heavy model (as 'Jetex' models go).

So that's the 'bad' news. The good news is that we noew have some very nice TSP L-3 motors that would suit these 'chuckies' very well. :)

At a price, mind, but quality never did come cheap! :whistle:
