I have just purchased used SA Spit. Can anyone tell me what are the recommended Control surface throws on this model?
Thanks

RE: Jamara Spitfire60 ARTF(+ retracts)!
This thread has been dead for a while but I managed to get my replacement SA Spit up and flying for my club's Warbird day! The OS 91FSII is running really well and the aircraft is a dream to fly. I kept the cowl cutouts to a minimum, disguising the inlet as the aircraft code and cutting holes in the firewall to take the outlet air through the bottom of the former at the wing root. I'm running a bit rich but so far have had no overheating problems. The dummy exhausts and radiators (recovered from my previous model) are home built. I did a bit of research and found that SZ-G was at times the aircraft of Polish ace Aleksander Gabszewicz so I added a few decals taken from info gleaned from the net to add interest if not perfect scale realism!
Here's some photos at home after the maiden and an "in flight" from the warbird day.
Unfortunately I lost the canopy in mid air last week. I've managed to make a half decent plug from the remains of my old SA Spit canopy. I am going to make a vacuum forming box so I can make a replacement as I don't think I can purchase one here in Oz. (Let me know if you can!) The Topflite canopy is too small.
A fellow clubmember also has an SA Spit painted up in Aussie MkVIII colours as per the real one now preserved at Temora NSW. He's running an OS120FS! Flies it at half throttle most of the time!
PS My all up weight is 3300g. CoG 100mm from leading edge. No added weight, battery is over the fuel tank for balance. Prop is 14/6 Master Airscrew K Series.

[link=http://www.hobbypeople.net/guru/hps_726297075.asp]Hobby People[/link] here in the states still offers a replacement canopy and a replacement fuselage for the SA Spitfire.
The [link=http://www.horizonhobby.com/Products/Default.aspx?ProdID=HAN4254]Hangar 9[/link] Spitfire canopy may work as well.
Someday I'll get to mine![sm=rolleyes.gif]
You did exactly what I plan to do to mine, model it after Aleksander Gabszewicz's. Nice job on the bulldog graphic!

Thanks EB. If I can't get a decent result from my vac forming efforts I'll have to ship one from the US. Is this model back on the market over there? Can't get them here any more.

Unfortunately no. Luckily Hobby People still has some old stock of these 2 parts from Global.
Here's Wikipedia's story on [link=http://en.wikipedia.org/wiki/Aleksander_Gabszewicz]Gabszewicz[/link]

Also, EB, I got the bulldog graphic from a photo of MH434 which was painted as SZ-G for the Chailey air show in the UK. (2006 I think.) Google SZ-G or gabszewicz. Hasegawa make a 1/48 kit which shows the detail too. My graphics are just printed on paper on my home PC printer then glued on with spray photo glue and clear coated with matt estapol.
Not perfect but cheap. When they look a bit tired and fuel soaked I just replace them!

RE: Jamara Spitfire60 ARTF(+ retracts)!
I have just started assembling the Sportsman Aviation Spitfire 60 that I purchased over 2 years ago on a visit to Australia!
I have been through this thread and gleaned lots of useful tips from Mac and others, thank you.
I have been looking forward to assembling this model, but now that I get down to it I am disappointed with the lack of detail in the supplied "instructions" - if you can call the single page of schematics that! I would hate to being doing this as my second or third plane (it is actually about my 15th ARF), as there are just too many questions unanswered.
However can anybody please give me some guidance re installation of the elevator and rudder control rods? The lack of pre-cut exit slots for these is giving me a headache. There is a nice solid V-block at the rear of the fuselage holding everything firm, but this seems as though it will interfere with cutting the locations for the exit slots. Does it?
Also, I have thought about improving control of the elevator by using a horn on each elevator half and two pushrods wires at the end of the wooden pushrod. Any thoughts on this? I don't like the idea of driving those large elevator surfaces from just one horn.
What about dual mini-servos mounted at the tail, with their tops sticking out of the fuselage, and using short external pushrods? (A but ugly and non-semiscale!) Or maybe dual standard servos up front and a couple of Sullivan Gold-n-rods or similar?
Your comments will be most welcome.
Thanks,
Bill

RE: Jamara Spitfire60 ARTF(+ retracts)!
Bill,
haven't checked this thread for a while....
Firstly, I haven't had any trouble with the elevator using the single supplied horn on one side and my Spit gets a lot of work. I reckon I have about 30 hours flight time on it in the last year (~150 flights).
As far as the exits go, place the horns where you reckon they should go and take a line from the servo arm to find the likely exit point and drill and angled hole along the line at that point. There is a bit of guess work but mine works ok.
The main issue with this model is that the covering does bubble in the heat (maybe less of an issue in NZ) and it is difficult to remove the creases although I have had success putting pinholes through to let the air out.
Have fun, it's a great flier!

This looks identical to my H&M Performance Spitfire (no longer in business) that is identical to the Hangar 9 Spitfire. I'm sure there is only one Chinese factory cranking these things out for various customers. BTW, mine flies great!

Sportsman Aviation Instruction Manual
Hi, I know this is an old thread but I recently picked up one of these kits, unfortunately it has no manual with it. Would anyone have one that they could copy and send on email?
Many thanks
Many thanks
