PT-19 from RCM plans

I have always liked the PT-19. It is very colorful and has a lot of character. RCM Magazine published plans in their 7/89 issue. It was designed by Walt Mitchell, has a 60” wing span and is powered by a geared Astro Cobalt 05.

There won’t be many pictures of the build as it is already built and I forgot to take pictures of the total build. I ordered the plans from www.rcmplans.com, took 6 weeks to get them, I started building on 11/7/2012. So here it is.

More pictures. I didn't take any of the wing construction. The sheeting on wing is 1/16". The top sheeting on the fuselage is also 1/16".

Nice work. It seems like the structure was designed to be light from the get go. I built a House of Balsa PT-19 a while back, but there wasn't much room to change the structure without having to throw away much of the kit and starting over. Just like you do, I like the look of the plane.

I was wondering what are you going to use for a motor. An old Astro Cobal 05 was basically a 250-300 watt motor.

Thanks Mike and Teo.

The motor I will use is an EMAX GT 28/12 a 970 kw 330 watt motor. I will be loading the battery, a 3 cell 3300 ma lipo thru the nose of the fuselage. I have done this on other models and is very easy to do. Just remove the prop and the cowl, that is held by magnets, then slid in the battery.

The weight with battery is 3 lb 2 oz. Flew for the first time yesterday, 1/3/13, early in the morning. Very overcast so the video is a little dark. Had two flight of 7 minutes each. It took 800 ma to recharge each battery.

It flies very scale like, very happy with the model. Here is a video of the first flight.


PT 19 (4 min 3 sec)

Ed,

Very nice plane. Can't believe how light yours came out for a 60" plane. Mine is a little smaller at 52" and it weighs 3 lbs 4 oz. The HOB version also seems to fly a little faster.

Nice job,

Teo

Teo, my friend just got the HOB kit for Christmas, I have not seen it yet but I have found gas models to be a little heavier to absorb the vibration of the motor.

Steve, yes it really flies that slow, a couple of time I thought it might just fall out of the sky.
