This thread is intended for all and any info relating to the RK Jungster 1 & 2 wooden aircraft.
Hopefully we can replace all the wealth of pictures and info that was lost on the Yahoo site closure.

I’ll kick the ball off with a few pics of a Jungster 1 re build I’m 4 years into.

Looks like some very nice work! Thanks for starting this thread. I’m working on a jungster 2 project n220y, I’ll post pictures here soon.

Cheers, I would love to see some pics of your Jungster 2!
It’s a great looking parasol aircraft, I’ve always wondered how one would look dressed up in Foker D8 colours
👍

Make sure you will fit! One year at OSH there were some Jungster plans for sale so I went to find one on display. The owner of the one there said it can be tight for tall folks. I'm 6'4 and he said I wouldn't fit.

I’m 6’1” and fit fine, but I am going to mod the seat as others have done and drop it a little and have it support the thighs more. 6’4” would be a tight fit for sure in a standard one. A chap Gunther is very tall and dropped his seat and fits well, I can’t remember his height but I think was taller than me.
Another mod needed for quick egress is to go to slim line instruments and move the panel and tension member forward a few inches otherwise getting out is a bit awkward.

I did some research into the D motors, nice looking units but the UL Power is lighter and more hp as far as I can tell from the specs.
The LF39 D motor has 125 hp and wet flight weight of 85-88 kg listed on the website. The Ul 350iS at 130 hp is only 78.4kg flying weight and the 350iSA (Aerobatic version) is only 81kg. I didnt see any mention if the D motors where aerobatic or not?, which is a bit of deal breaker for a Jungster.
Whilst the water cooling of the D motor is nice in a way, I think I prefer the simplicty of the aircooled UL units over all.
The D motors sounds like they would be good fit for say a RANS S6 OR 7 type aircraft though.

Plane was previously flying with a C90. I bought it from Howard Allmond, complete minus engine/prop. I’ve installed a lycoming 0-235 L2C and Cato prop. In the process of making a new cowling right now. Got the engine all foamed up, gonna start rough shaping today, I’ll take some more pictures too.

That’s great!! Thanks for the pics !
Do you know if the large sheeted gusset area on the inside of longerons is on the plans, or a mod?
It’s pretty much exactly what I am looking at doing to beef up the Jungster 1.
It will add some weight but not much.

Here’s the engine all foamed up. Ready to start shaping it. Also my suspension biscuits are looking a bit tired and I think they should be replaced. The plans give the dimensions and say they are from a 57 Chevy engine mount but doesn’t specify the exact vehicle. Anyone know?

Have fun shaping the cowl, that’s a bit of a mission job. Sorry I’m no good to you on the rubbers.
I like the fully sheeted inside of the 2.
Keep the pictures and info coming, really isn’t much info out there on the 2 that I’ve seen.

I cleaned and inspected the wings and they are in excellent shape. Each wing was built 2ft longer than the plans.

I’ll check that out! Looking at my plans right now. Looks like they added two more rib bays to each wing root. Also the sheeting on the fuselage sides is on the plans.
