Ordered another ARTF on Monday

As title say's.....can't wait for tomorrow , should be here and I will be like a 6 year old on Christmas morning lol.

**LINK**

It has flaps which I have never flown with and I am a wee bit excited but also nervous about this. Hopefully have the maden flight this weekend if I get it all kitted out and ready.

Looks like a nice plane and at a good price too. Looking forward to seeing the maiden flight video what engine are you putting in this?

Hi Jamie,

Good luck with this. I have been flying one for about a year now. It is great fun.

I threw away the elevator and rudder pushrods and made my own, as the supplied stuff looked dire. Pull pull cables to the rudder ran through the existing snakes, and I made an elevator pushrod whit a "y" at the back to each elevator half.

There was also a bit of fiddling required with the ailerons and flaps, but well worth the effort. The horn position holes were all in the wrong place i think. I plugged them up and made new ones.

One of my u/c blocks came out of the wing some time back, bad landing or bad glue? I know what I think! But it was easy enough to stick back.

I also fitted bigger wheels which fit inside the spats easily, for our rough strip. Oh yes the u/c legs needed to be bent to a more scale angle, I found a 3 view on the net, and bent them in the vice, no problems. This last winter I flew it without the spats, but they do add a touch of class.

I chose to fit an Irvine spinner, I preferred the shape.

I have a Saito 82 in mine, it has masses of power. It fitted it sidewinder, with just the silencer protruding. I cut a cooling exit hole in the underside of the cheek cowl. I recommend cyano-ing some glass reinforcement inside the cowl to reinforce any cutouts for the engine, it is very thin. The Saito may be powerful and reliable, but it is not the smoothest running engine.

The flaps are really effective, at the weekend, at the Bickley scale day, someone commented that a model like that shouldnt be able to fly so slowly. This really makes landing on our short strip easy.

The flaps give very slight up elevator trim, but not enough for me to have bothered with a mix. Try them up high first.

Oh yes, the alum tube was a poor (too tight) fit in the wings. I spun it up in the lathe and sanded it down with some emery tape. You could do this in a drill too. or by hand with emery tape. It fits in my Berlingo in one piece anyway.

It is a very enthusiastic snap roller, it is possible to pull up into a stall turn, snap roll on the upline, and then do the stall turn. Fun! As you would expect with a short coupled model like this, the elevator needs to be treated with respect, keep the movement small, it is very powerful.

A fun model, enjoy it.

In summary, it took me a weeks holiday to build, and has given me hours of fun. Considering that it usually takes me 2 years to build a model, it was well worth it.

Thanks for the replys. It hasn't arrived today to my dismay !! SNAIL MAIL...

Im putting a Jen 90 in it with a cowel muffler which I already have. I phoned the company before I ordered it to make sure the 90 was ok. He said yes so it will be ok hopefully. How much deflection should I dial in on the flaps ??

1/4 inch to start off ??

I presume when landing under flaps I need to carry the throttle a bit to compensate for the sink rate ??

This is new to me the flap thing

It arrived this morning and its my 4th Black Horse model that I have had. The Build quality to me is excellent and covering included. All in all I'm impressed at this moment. The 90 Jen will fit just but some holes needed to be cut in the lovely cowel but the entire engine is soaked up inside it other than the 2 exhaust pipes and the adjustment needle will be out by about 5mm I think. Time will tell on that. With a 90 up front this thing is going to go some !!

Think I might put my digital heli servos in the wings. A standard futaba 3001 on throttle and I think I have a couple of 3010 servos for rudder and elevator. It will be 2.4 ghz I think but I do have the 35 mhz that is a posibility.

I'll try and take some pictures and post them if the excitement doesn't get to much lol

Charles I'm not sure what the push rods were like with your one but these are ok looking. They may have changed it....not sure. The elevator has a y at the servo end and there all metal push pull system with metal clevises for fitting. Rods are about 2mm in dia. The aluminium wing tube fits tight and snug but by no means to tight. Maybe I'm lucky or maybe they have sorted out some issues on the kit...not sure. Time will tell on the ailerone and flay horn holes. Think Ill start with the engine and cowel mounting. Then fit radio in bay and follow up with the tail gluing and connection's. The wings dont look like they have much work involved so I will leave them till last and hopefully all will go well.

Hi Jamie,

It should move with a 90! Make sure there is plenty of cooling outlet from the head.

My flaps have two settings, half and full, the max I could get was about 45deg.

I dont trust little grub screws which could slip on the elevator link. I was also suspicious that the wire pushrods could bind, a model with a sticky elevator is horrible to fly. I used a carbon tube as a pushrod.

Good luck,

Charles

Hi, I fley the Midget Mustang on Wedensday and I have to say it is a lovely plane to fly and of coarse own....

I would recomened it to anyone who is considering it. My main problem is the engine but I think I'll start a new post about that subject in the correct part of the forum... Up till now I've had 3 or 4 half tank flights with it and love it. Had a dead stick on the second flight and its glide is docile and floaty. No fear of a nasty tip stall there at all as far as I can see and the flaps aid it in landing no end. All round 5***** for Black horse again from me.
