SR71 1:10 SINGLE TURBINE

I presume you are fitting elevators and not just elavons, it will not get of the ground without
What thickness the is the planking

[badass]
Yes, all 4 up/down, I've got the Futaba 14ch tranny, i have it allready linked up for my Concorde so no problem there.
Planking is 1/8 thickness all surfaces less for cockpit and accessories where it's a bit thinner, the chine is 6mm diameter, main leading edge is 22mm ( being sculptured down to 12mm), trailing edge is 9mm at body to elevators, and down to 2mm at tip, fins are fixed solid.
I haven't gone for the droop on leading edge of winglets, so they start at 6mm like the chine.
For those not in the knowledge of the SR71, the chine is the leading edge along the fuzz (sorry, but it may be necessary in the future comments)
Please, keep questions coming in, it is a beautiful plane to build, a back breaker at times, but sleek and very streamlined
Because all surfaces are so streamlined, it is important to get the chine correct
Hope that explains a lot, please keep the questions rolling in especially from tony (BB) as you have experienced the same plane at the same scale

Been working on retracts, servos, electronics, planking and fuz

Having lots of problems with my HK retracts, having bought 4 three now dont work :evil: :evil:
I am at the stage where im ready to call it a day with the hobby
Shes looking good Mike

Can you email them, if you can't find a solution perhaps you can do some work on one of your others, then come back to it at a later time, don't give it up, boz

Use email

Wow, looking good there bud

Faulty retracts are a big pain in the backside.

My Dynam Spitfire had a faulty port side retract, so i took it apart, cleaned it all up from their horrible grease, re-flowed the board by putting it in the oven at 200 for a few minutes.

i took off all the wires before doing so

and it now works a charm.

most of the time, it is just a dodgy microswitch, or a dry joint.

Thanks
I had a faulty retract on the sr71, smoke and a crackling noise gave it away
I had to replace it, luckily, i had one spare
Nice tip, I haven't a clue when it comes to a printed circuit, lol

(TS)
I don't think i will need a scoop, if you look at the last pic I could make a balsa/mesh slotting holes
It would also work as a foreign object catcher

I also have the pilot in position, will take a pic tonight

[badass]
Had to put the pilot in because his butt sits on the servo for the front retract doors, lol

[badass]
I am making progress with the working service
Also, the nose wheel doors, and turbine intake
Made with pro skin, then mesh, then 3D print
Next is the inspection door(central) to access receiver, battery etc.

[badass]
I can hear you saying "there is a rag on the turbine ",
Don't worry, I've put it there purposely, when I paint it, it stops the paint getting on the turbine, i can reach it from above

[badass]
Today i worked on the retract doors
