Official Black Horse L-39 Albatros 90mm EDF Jet Discussion Thread

[envallm]

Thinking of buying the BH L39 plane.
What is the best, most powerful 90mm power system combo , of fan/ ESC for 12S setup?
Thanks

I contacted schubeler directly and they affirmed what was mentioned in here as the best setup for this airframe (DS-51-AXI HDS® (90mm) - Schubeler) Curiously, they also said that the equivalent HST 93mm would be the optimal choice, but not typical for hobby modelers, given the cost. Ill be going with the HDS and 1125 Kv per schubeler. I also to use the phoenix HVF 160 AMP (Castle Creations Phoenix Edge 160HVF 50V 160-Amp ESC w/Fan [CSE010-0127-00] - AMain Hobbies)

dsmithwc04 / Aussie1 Could you please post some pictures of your installation of the JP Hobby ER-120? I'm afraid that the front wheel will be visible from the side, in retracted position. Do you think the 100° mechanic would fit into the nose?


Cheers

I'm thinking of getting these retracts for the L-39, but curious if the JP ER 120 nose wheel does protrude when retracted into the bay. I didnt see a pic here. Does anyone have a pic of this nose wheel in retracted position? Thanks plent

What is your budget? $250, $500, $750, $1000+?

Anybody else other than rsunleaded notice the push pull tube routing is way off from the factory? Did everyone else do the same thing and use nylon inner tube and curl it 180 degrees back towards the landing gear? If anybody has pictures that would be very helpful

I’m using JP Hobby ER-120 retracts with brakes but I’ll take pics of whatever anybody else may be using. Thanks!!!

Hello All,
This is Valery, Sergio's wife and I just purchased the Black Horse L-39 Albatros 90mm EDF for his birthday and I have been looking for the tricycle retracts system with breaks and can't find them anywhere? Wouldn't Motion RC carry them as they sell the jet? Any suggestions as to where to get them as everywhere that I have looked is sold out or out of stock?
Also, would your 8S 90mm EDF motor and ESC power this jet sufficiently? Any and all suggestions are welcome! I want to get as much as I can for the jet so he can build it ASAP! His birthday is 07/04 and I would love for him to have everything in hand so he could fly it by then? PLEASE HELP!!! :)
Thank you so much in advance!

Here is the gold standard retracts for this jet, but the E-Flite 60-90 size retract set will fit the legs that come in the kit. This is what I am using on mine, and I have a turbine in it as well. https://www.turbines-rc.com/en/strut...ontroller.html

Looks Great!!!!!!! Glad your liking it. I might still do the Blackhorse L-39 in the future, but for now i'm holding off.

Will we get to see a video of this gorgeous jet?

Here is a video of my jet, not very good, but all that I had on the day. I'm using a one litre juice bottle with a felt clunk, no header, and it works perfectly.

What a silly rule that is!! It must have been written before micro turbines were common. We had a similar rule here in Australia that said that all turbines were subject to a heavy model inspection, even though some of mine weight 3kgs. Now, it is just a one off turbine inspection. I reckon that with the X90 and heavier batteries for the inspection, you will easily make the 12lbs dry.

HI AUSSIE I am looking to convert one of these using my xicoy X45 what size fuel tank did you manage to fit into it and how long a flight are you getting

[406PIlot]

Finally, I now have four flights on this jet. Fantastic performance with the X45, almost 1/1 power/weight ratio, so great vertical as well. Because of the big wing, it takes off in 30 metres and lands super slow, so that is good for a jet. I have a old turbine jet pump, so am in the process of making my own smoke system using a old brushed motor ESC, so yet another learning experience! IMO, the perfect engine for this jet would be the new X90, as physically, the jet is not much smaller than a Skymaster 2 metre Viper. I also fitted a gyro which smooths it out nicely and the Unilight system is incredibly bright, even in bright sunlight.

I thought it went up, but honestly wasn't sure if I just had the wrong price in my head.

[Twowingtj]

I noticed yesterday that the price on several of the larger Black Horse planes took a jump. I know that Motion RC doesn't do this on a whim. There are usually cost jumps that they've had to take on the either get or ship the product.

[406PIlot]

Did the price on this go up 100$??? I thought it was 799, but motions site is showing 899$.

[406PIlot]

I agree.. I'm still figuring everything out. And I may just do that run bigger batteries and maybe sperate gear and brakes all to thier own batteries as well.
