Official Black Horse Spitfire 2000mm ARF Discussion Thread

Thanks Hans—- how is the performance with that set up?

Hi

Compared to my Spitfire with DLE30 it flew the same.
Have to make a remark that I fly scale, with this setup plenty of power for me.
Also if you want more pull and speed you can move up with prop diameter and pitch.
Motor I mentioned is rated for 80A and 2750 watt.
I used max 2400 watt.

I would still like some more input on power combos guys are using for this plane—- thanks!

Hi

I have older Spitfire from BH with a 10S setup.
Motor SK3-6374-192
ESC Phoenix ICE HV 120
Prop Ramoser 3 blade 17.2 inch/ 23 inch
Current draw max take off 55-60 Amps.
Current draw in flight 15-20 amps
Will update after next flight because my telemetry data wasn't logged right.

Regards Hans

I had the same issue. Once I connected I shaved a little from the side. Seems it will work fine.

I gave a small bend

Guys, are your gear axles angled like this? Wondering if I should shim the retract unit to get them more parallel. Probably not worth the effort though.
Thx. A few more finishing touches and should be ready to go....as soon as the field dries up!

[Martyt]

Sorry, I should have been more clear—- I meant electric power set up.

[Twowingtj]

Mokis are nice. If you really want to hear a sweet sounding, high performance engine, check out Valach.

[Aros]

Moki! Moki! Moki!

Question: what would be the best total power setup if you wanted more than enough power and money was not a concern?

[Martyt]

A cool thing to do would be to use a rotary drive system (RDS) to operate the control surfaces—results in hidden linkages and no horns needed— glider guys have been using those for years and scale guys are now using them more and more.

Am currently building a Hostetler 34% mong racing bipe so this will be a nice plane to get together from a relaxation standpoint (but with frustration mixed in as well regarding anticipated fitment issues and supplied hardware)— still nice to get a plane like this in the air and not spend a few years building it. I have not started my build but reinforcing gear area in gear box area is always a good idea so long as weight is kept in mind. Lots of guys who have built the Mick Reeves Spit and The Meister Me109 reinforced the gear area beyond what the plan showed. Here, the manufacturing process probably went with lightish ply (am only guessing). At minimum maybe triangle stock and or CF fiber mat—-weight gain is minimal. I would also use Hysol 9462 vs regular 30 min epoxy— just my 2 cents without having really looked at this plane

I sure remember back in the day, building Balsa & ply aircraft. I'd have to perform several modifications. These days it looks like a lot of the work is already done for you. I absolutely love the Spitfire. Man, what an aircraft for the time & even today. It's so incredible people built these aircraft and, now we can have an RC model version to fly. Keep them coming Motion RC!

While I am here, did anyone do any sort of reinforcement of the gear mount? If so, what, how? Cheers....

Super Marty! I got mine late last year also with elec retracts.

I was going to post anyway sooner or later, but the supplied ball links are kinda cruddy. Holes not proper size, only a few I could ream out for a good fit with the ball. I ended up using mostly these.....https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
Others have used dubro too.

The tail wheel will take some fiddling. As supplied, when I did a dry fit, the arm for the pull-pull would hit the bulkhead. So by playing with the set screws on the shaft, I was able to adjust the arm, but I still had to dremel some space on the bulkhead to allow smooth pull of the wires.

Otherwise, pretty nice fit.

[Martyt]

Just got mine today via FedEx. I was pleasantly surprised that it came with electric retracts! I was expecting pneumatic ones. Sticker on outside of box stated with electric retracts included— sounds mine might have been one of the first? In any event, will plan on going with 190 electric for the motor.

[dsa44]

Brilliant T007! Thank you! Remounted the ball link on the underside of servo arm and alignment much improved.

[Terminater007]

Try mounting like this

[dsa44]

Guys, I am dry fitting together and having a devil of a time lining up the aileron connection. What did you do to get this aligned? Move the aileron mount? Widen the hole towards the outside? Anything else to consider?

Thx all.

[dsa44]

Well I pulled the trigger for an early xmas gift to myself, LOL, and just so you all know, they are now shipping with ELECTRIC Retracts!! Can't wait to get it out of the box and test fit. Cheers, DSA
