1/5 Mustang


Recommended Posts

Being a cheap modeller I often get things that I might use one day, one of these was a local Mustang fuselage based on the old Byron kit. I managed to borrow a foam wing and stab from a Byron kit and then made my own wings and stab that was sheeted in balsa and then glassed and filled. The wings were made for Robart retracts to be used, the Top Flight kit is about the same size so these retracts were the ones used. For some reason I then stopped work on the mustang after all the building was done and packed away. 

Byron was at a loose end after the MB 5 was returned to me when I needed to get it ready for flight and said he really enjoyed working on it so I suggested he take the Mustang and do some work on that. He has done a great job so far and I think this airframe will be great to take to the flying field with the MB 5 so people can see the difference.  The wings on real Mustangs were filled and painted to improve airflow on the wings and fuselages left in bare metal so our model will be the same.

The Mustang was originally set up for a 45cc Super Tigre but we changed our minds to try it as electric. It is strange how on a project like this you start doubting some of the work done as I had made up my own templates for the wing section, retract mounts and then CG. I had no plans only the original foam wing which was not cut so an exact replica was not easy to make. The stab was also changed to make it more scale. The Byron is a 40 year old design that originally had a Quadra 35cc on a gear drive with big plastic 4 bladed props. I decided to get the airframe flying to see if it all worked out. CG was a little forward according to my calculations but close to what Byron recommended. As you can see we are now mid winter in South Africa so the ground is very hard and dusty with lots of grass fires.

The covering is a metal tape that Byron got from his work which is an airline. The tape is used for emergency repairs and is known as speed tape, really sticks and is very thin and quite light. A real sod to work with. The roll of tape is quite wide at 30cm so better than most other metal tapes on the market. Byron is making good progress with the fuselage and I have been making fiberglass moldings for the guns and drop tanks.

We have a Futaba FAAST receiver in the aircraft with the normal spacing on the antenna's and had no problems so far. There is no Carbon in the fuselage so this will also help.

 

One aspect I do enjoy when building a scale model is reading up about the aircraft and the pilots, this aircraft's story is quite interesting. I found it in a Flypast Magazine. We also do not fly any competition so we build and finish to what we like or want to try.

Byron delivered the airframe back to me on Friday so that I could double check all the equipment that had been refitted and also for the tapping of the bolts for the spinner. All work done on Saturday so we went out early yesterday to fly again. The question from Tim regarding the potential  interference had me doubting so we did additional range checks to ensure all was well. I had also reduced the forward rake on the undercarriage as the ground handing was not as good as the MB5. I am glad to report that all went well and we had 2 flights, this is a very smooth flying aircraft with plenty of power.

We flew at a scale fly in 2 weeks ago and had 2 flights with the Mustang, the first time it has flown from tar runways. It was quite hot and gusty so not the best of flying conditions but the Mustang did well.  The video is good but my technology skills are not great so I am not sure why it is a reduced screen!
