Nothing wrong with air retracts - i have had many. They usually require more maintenance to keep them working perfectly. On my jets I replace all air lines every season or two, which is a lot of work but they have not failed me. I have seen several larger scale air retracts not come down when it is time to land but I have yet to see that with electrics. It's personal preference I believe more than anything.

Again, just my take.

I'll probably try the pneumatic valves that robart sells that slow down the gear deploy, if it's still not to my liking i'll just chuck some electrics. I would hate to belly land this.

Hey Jasmiller,
This is my first blackhorse build!
How did you know the distance to measure and mark where the flap/aileron attachments go for the horns. I'm looking at your pics and soft marked mine. But want to ensure that I'm getting it right and understand how you aligned them, etc.
Did you install the servo then the control rod and see where it would line up on the aileron?
I'm assuming that's how you got there!
-Thanks
S.
**Update**
I just looked back at your earlier post, you did the servo installation first.. so there i think lies my answer :P I don't have my servos yet, so I'll just glue the hinges tonight. Just so I know, there are 2 types of hinges, Long ones (67mm ?) and Short ones (44mm) . The long ones stick out considerably more than the short ones.. As your pics you used the shorter hinges for Ailerons. (44mm)
I took a peek at the fairchild manual and the same appears to apply, 44mm for ailerons and 67mm for the elevator and rudder
Where are the longer ones used?
Ta....

I was looking to see if you knew the exact spots that the long 67mm hinges are supposed to be installed.
I called motionrc and opened a ticket and left a voicemail to the manager to see if we can get an updated manual ASAP.

Working on flaps and tail feathers.
You will need to cut the bottom portion of the hinges that are inserted into the flap, about two lines up. The part of the hinge that is connected directly into the wing can stay the same length. Only epoxy the hinge into the flap at this time, dry-fit into the wing. Pushrod connections need to be made before permanently installing the flap to the wing.
At this time I have epoxied the hinges into the rudder and elevator, not to the horizontal or vertical stabilizers yet. You will need to run your pushrods thru and remove the covering where they exit the fuselage. Also, the elevator and flap hinges can be installed. You will need to feel around for the small slat and remove the covering with a sharp blade. Gently push with force, the hinges will go in and fit well. I used hysol to attach the hinges.

jasmiller Thanks for the response tonight, I figured as much that the longer 67mm were for the flaps and when you mentioned you cut them to make a perfect fit inside the flap then it all made sense and came together.
Did a dry fit tonight, Like you , I cut about 2 notches off a 67mm hinge and placed those inside the flaps. I noticed that there is a little bit of precision involved if you want the flap to sit flush and perfect. So all of you perfectionists out there, make sure you do a dry fit and mark the hinges so that when they are epoxied, you don't push them too deep.
I'm completely out of 30 minute epoxy and only have 15minute. I'll wait until tomorrow to glue these after I head out to the hardware store and get some 30min. This way there is time to align and set the hinges in the flap while it's flush in the wing. As jasmiller said in the previous post, wait until you get the servo & pushrods in and figure out where the horns will go.
So, glad to be following along with jasmiller thank you for your help!! You're probably going to lap me now in progress as I move relatively slow with my builds and take my time. But glad to have reference photos to look at.
-Regards

Thank you, it may take some creativity to get my retracts to work with these struts but that's ok. I should receive my spitfire today, unless there is a shipping delay.
So don't be surprised if you don't receive the manual. If you do receive one, you will be a hero if you scanned it and uploaded it :P

Was thinking about picking up one of these:

Can anyone comment on the quality?? Plus not sure if I feel safe cutting the figure in half to make him fit in the cockpit, I may just get one of the plaster busts and paint it.
