J-Power / Robbe GROB G 120TP 67" Wingspan






I've been searching on RCG for a thread on this plane but can't seem to find it anywhere. It is a very interesting plane with a 5 bladed prop. I would love to hear from other owners of this plane as I will be starting my build shortly. AtomikRC carries these and they are currently on sale for $168 shipped! Great price for a 1700mm model!
Sadly, AtomikRC sold out and removed it from their site

Here are some videos (brush up on your German):

and it appears there is a version 2 out now:

Oh man that sucks, I noticed it go into backorder this morning, and now it's been removed form the site. Was such an amazing deal there. Mine has shipped so I should have it next week.

Awww!!! At that price, that's an awesome deal, beautiful plane...the real one and the J-Power model.

J Power offered me distributorship in Canada couple years ago when I was importing FMS/ROCHobby. Your price is less than the wholesale (then you have to add shipping from China on top of that) two yrs ago.

Crazy deal on the airframe... Amazon.com free prime shipping, under $40!!!!!!!!

Note that it doesn't come with the canopy... it's just a bare airframe, no hardware included.

Starting the build


Ok first day of work, need to hinge the elevator and rudder. Easy process of cutting the control surfaces off and then gluing in the supplied hinges. Sometimes this can get a bit tricky to line things up, but patience is key! I'm using small amounts of gorilla glue to secure the hinges in place. Sometimes I use CA but I find on occasion I wasn't quick enough and I make a big mess trying to rip out a half inserted hinge. I'll make sure my results are good and then tomorrow do the ailerons.

I just purchased a complete with canopy airframe. Can anyone share with me the CG listed in the instructions? Any news from the peanut gallery on this one? Peters wolf - what is the status on yours?

It's a big girl and is graceful in the air with their thin, tapered wings.

I really like the color scheme on the BH version

And the five bladed prop is a nice bonus too
