Official Black Horse Spitfire 2000mm ARF Discussion Thread

[sfmadmax]

was on the worldhobbies.com.au website , must be the 2020 built ones.

its probably a misprint , if you read the fine print on the actual contents it says nothing about electric retracts.

INCLUDED AIR RETRACTABLE LANDING GEAR.
AIR UP, AIR DOWN WITH OLEO STRUTS.
ALL BALSA – PLY WOOD CONSTRUCTION.
COVERED IN A HEAT-SHRINK FILM

Even the manual is the same rev. It doesn't come with electrics. If it did. I'm sure the price would be up another $200 or so.

Everyone is so hung up o the retracts. Gotta look beyond that . Lol

[sfmadmax]

As is. I have the stock retracts installed, will post pictures soon. Not too difficult but the tubing is hard to work with.

Thanks for the feedback jasmiller , I'm also going to do the same as you. Going to use the stock gears, but with robart valves.

Do you have the full list of valves you used ???

I decided to just use a wheel collar on one of the tube lines to slow the air down and thus offset the gears a bit.

Hi Pilots

I got me a second spitfire version 1 BH136, this is already with elektro setup,
Turnigy Aurodrive 6374-192Kv and a Castle ICE2 HV120 A ESC, prop is Biela 18X10 3 blade.
Former owner flew it with 10S5000 LIPO.
It has some wing damage underside and I will repair it with invasion strips.
Easy way to do see pic from jun 5th 1944...

Another sexy plane on my wish list. Spitfire has always had a special place in my heart.
sitting in one was an experience, so the fly a huge RC one would be very cool.

I’ll look up the part number. I used the red valve. You can adjust air flow on the unit itself. Works great. I have in a few othe planes.

I have that part... See pics...

I opened the retract box today, i'm not happy to see that they did not include a fill valve stem or cluck. I'm probably going to pick up the robart one at the hobby store tomorrow.


So it took my almost 1 hour to figure out how to get this hard plastic tubing onto the stems. They were a complete pain, i'm not a fan and really tempted to toss everything out.
I love those quick disconnects though. I'm sad that they don't work with the soft tubing.





The problem is , I would love to re-use the tank with the robart 1/8 tubing. However,

The tanks stem is slightly bigger @ 3mm. so it will fit, it will stretch, and it will have a tenancy to slip off , unless its secured down somehow. I have to get creative on this, OR just buy the robart tank that has the stem that fits the 1/8th tubing. I'm trying to save $$$ where I can and re-use parts. so i'll try to spend some time and figure it out.




These robart parts, went together in less than 5 minutes.. a little ear wax and the tubes went right on the T connectors... and I locked them down with the Line Retainer Nuts, Tomorrow i'll go out and get the brass fittings , you're not supposed to use the retaining nuts on plastic, i just wanted to see how it worked out.




Here is a pic of the difference in tubing, robart on the left and stock tubing on the right. the pic aint that great.


So, good news is the Robart, 1/8th tubing will fit over the retract cylinders, again, need to secure it somehow as the retaining nuts won't work since it's not a robart part. I may go see if the hobby store has cylinders that would drop in.... will see.... more to come!

I used stock tube from retracts and then Robart tube to connectors. Works great.

I ended up going out and buying the rest of the Robart Parts , but used the stock retract cyclinders. Everything works great!

I really like your PSI gauge, what brand / model is that?

I printed out the exhaust stacks scaled up to 113%.

Just curious, I was planning on coating the interior with a poly urethane, Just curious what others are doing to protect the wood from any possible fuel.

Hi

I posted my build log at beginning of threat.
And yes I fly with fuel and I coated interior with PU lacquer.

Horizontal stab is now attached. I cut off some covering on the top to help secure. There was a gap at the very rear so I have a clamp for compression.

the push rod for the rudder is too short. I had to order additional push rods. Elevator is good.

Not much left now. Get fuel tank installed, break in engine, mount and fly. I’ll take some additional photos of my set up using a power box and spark box.

Had same issue with rudder rod. Try turning the servo around with spline facing rear, just managed to get it to fit in length.
