Thanks dsa44 for the response. I have programmed a new one to cut with my cnc. I have it dialed in pretty good and plan on ordering a single flute bit to cut the 6061aluminum I picked up. I tried it with a common 3 flute wood but but the aluminum seems to melt to the bit 1/2 way through. This is my first “metals” cnc project so I don’t have the bits needed on hand. I have made a perfectly fit replica out of white oak but decided I best replace the aluminum part with aluminum. (10 times stronger than oak). Thanks again,

Impressive! I think it would be of interest to share some pics of your CAD screen showing the design, as well as your CNC machine, prototypes, and finished trunion! Cool beans!

Hello fellow, spit fire brothers. I am brand new to this forum and looking for some help. I’ve recently just put an airplane in the air. First time in 12 years, my new club was having a swap meet and I bought a few used planes.(I don’t recommend buying used planes) I came across what I believed to be a screaming deal on a 2000 MM Blackhorse spitfire. Plane seems to be in great shape. However, though the pilot only put a few flights on this plane, his last landing was a bit hard, breaking part of the retract. (Electric) i’m going to attempt to take a snapshot of it in hopes that somebody can tell me where to either purchase this piece or a whole new assembly. I appreciate any help any of you can give.

Best bet would be to search on aliexpress for 'trunion' if you can find a size match. Otherwise, just get a new unit. Again, you will have to match the size. MRC has them, but out of stock. Good luck!

That’s not a bad idea, will have to consider. There is big gash on the elevator and got some nicks on the wing. Its tough for me to live with just like that.

[Shackhacker]

Have you considered cutting out any bubbles and going over the top of existing? Won’t be a nice as the ordinal , as they did a great job before market. Not sure how bad yours looks but it is an option.

Is there any way to recover this airplane? Had some hangar rash on my elevator, obviously it’s epoxied in and would be an easy job with a normal ultra coat airplane. But with this print on covering seems like it will be tough. Any ideas?

Thanks fellas! Second flight was a real joy too. Unfortunately, lost one of the underwing radiators, I guess I did not secure it well enough. MRC out of stock, and although I have some other ones from my prior (RIP) TopRc and Seagull versions, they just don't look right, and clearly dis-proportioned.
So if anyone has a spare radiator, would happily purchase it from you. Thx

Nice job! Love the 2 point greaser!

[TwistedGrin]

Agree this is a larger yet light wing loaded R/C .......another Blackhorse Jewel to fly

Glad you were able to balance that spinner !!

Finally got the chance to maiden! Very nervous, but such a nice flyer, needed a bit of ail and elv trimming, Here is the maiden flight and landing, nothing fancy just some high passes getting it trimmed out....see the link for specs. Can't wait to take it out again and try some aerobatics! Cheers

Great landing! Looks beautiful in the air too.

Still flying this great bird.

Despite mt best efforts - I could not get a satisfactory long term repair on my left wing damaged retract mount.....so I ordered a replacement left wing and discovered ..... It is slightly different:

1. 57 grams lighter
2. Figerglass sandwhich plywood bracing in the inner section from the aileron servo to the wing saddle
3. The retract bolt holes are further apart and are 4mm bolts instead of 3mm bolts - requires widening the original electric retract mounts to allow the bolts to deploy

Everythig else is the same regarding wing shape, covering, hing placement etc etc etc.

It does not ship with the long hinges for the flaps or the short hinges for the ailerons
It does no ship with the 20mm cannon covers for both wing tops

You will need to purchase the plastic parts package, linkage package and stut cover package/s separately as needed.

Thinking of picking one of these up, but before I drop 1,000 bones on an airframe, can someone tell me if a 32oz DuBro fuel tank will fit in the nose?

I ask, because I'm looking for a home for an engine. A big, thirsty, Italian kittycat of an engine specifically.

I picked this up for a song, glow fuel is relatively cheap in my area(25 bucks a jug for 5% Omega), it runs like a swiss watch. But I didn't buy it just to make a castorey mess of my toolbox. It needs a forever home! One that lets me take it up once in a while, spend an afternoon filling the skies with blue smoke and ring-a-dings aplenty. And it'd have BOATLOADS of power for this spit! Would turn a scale sized 3-blade easily! But its voracious appetite means I need to find room in the aircraft it goes in for a 32oz tank...

Four more flights logged this evening... locked in rock solid and silky smooth. The power set up with the 18/12APC prop is now confirmed with no doubt....nice speed and power wihout overheating any components. Landings are very easy and consistent.....which leads to no fuss confidence.

Excellent Hans and great photo shots sir!!

As reported on my 10s power set up.....the power and speed was a little sedate or perhaps a bit slow. I bumped up to an 18x12 pitch prop (APC) and the speed and performace is greatly improved. eCalc had the former prop 18x10 XOAR pulling 148w/lb at a top speed of 73mph. eCalc shows the new APC 18x12 pulling 162wlb and top speed at 81mph. Additionally I found my aluminum prop spinner was digging into the XOAR prop and may have been distorting it at high loads.....the new APC prop allows more thread on the prop nut and seems to be much quieter in flight.....it does create a different pleasing howl at full throttle.

The flight perfomance with the different shape of the APC and higher pitch prop now allows my BH Spitfire to fly with authority and power I imagined a Spitfire to be.

I did replace both retract motors as one died and the other was really slow.....so I have gone through three of these retract motors and ordered four more.....it takes me about 10minutes to swap out the retract motors now - LOL

This model looks and flies really nice.....excellent

Very nice!
