Mark Perry 1 Posted March 21, 2017 Share Posted March 21, 2017 Hi - my first real post, and it's a question ( hope I've done it correctly ) I've saved an old Bipe from being put in the dustbin but I need to find out some details to help me complete the build. First question - what is the make & model ( 5 pictures in my one and only album). 46 inch span, foam wings ( built up wing tips ) Once identified I'm hoping to find out the C of G, interplane strut position / shape / method of fixing to wing etc Any help appreciated Thx Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted March 21, 2017 Share Posted March 21, 2017 Someone will spot it Mark shortly But ballpark C of G for a staggerwing bipe is to look down at the wings in plan view/ from above, and divide this by 3, to roughly find One third distance from the leading edge, and this usually works out quite close to the plan position Your c of g should be near the leading edge of the lower wing from my view/guesstimate Edited By Denis Watkins on 21/03/2017 21:10:47 Quote Link to comment Share on other sites More sharing options...

Paul C. Posted March 21, 2017 Share Posted March 21, 2017 Pat French Bucker Jungman possibly. I think it was 40 powered, foam wings, top wing was held on by bands in the middle and outer struts were plastic positioned by small dowels in the top and bottom wing. That's my guess 😀 Paul.

Nigel Dell Posted March 21, 2017 Share Posted March 21, 2017 99.9% sure that is a Pat French Models Jungmann. I built one years ago for an HGK 40, a heavy engine but the model flew really well as I remember right up until my TX batteries failed (they were fully charged and it was a new radio) and the poor Jungmann looped until it ran out of air! The fin and rudder look a bit botched but otherwise as long as it is straight it will fly fine and sorry I don't remember the CG or anything like that it was 35 years or more. Looks like Paul and I were typing at the same time!👍🏻 Edited By Nigel Dell on 21/03/2017 21:25:44 Edited By Nigel Dell on 21/03/2017 21:26:40 Quote Link to comment Share on other sites More sharing options...
Paul C. Posted March 21, 2017 Share Posted March 21, 2017 Just beat you to the add post I think Nigel 😀. Mark take a look at some plastic strips that you can get from stationers they are the ones that are used to bind A4 paper together they even have an airfoil section of sorts. There are two for each wing and slot I to 4 short dowels, the center elastic band holds the top wing in place. If you feel around you might even find where the original dowels were. Best of luck, Paul. Quote Link to comment Share on other sites More sharing options...
Mark Perry 1 Posted March 22, 2017 Author Share Posted March 22, 2017 Thx Gents - Bucker Jungmann looks promising, but I can't find anything on the Pat French connection ( don't try googling French models ! ) A great tip on the plastic struts - I'll wait a bit longer and see if anyone can come with a plan or any pictures Quote Link to comment Share on other sites More sharing options...
Allan Dryden Posted June 27, 2017 Share Posted June 27, 2017 This is definitely a Pat French Jungmann as I built and flew mine back in the early eighties and I had it for about six years when I gave up the hobby for a while and sold it It flew very well upright and inverted and will knife edge as well with ailerons only on the bottom wing and i flew it on an OS 40 FSR with Sanwa radio The C of G was found easily as the centre ply support for the top wing had a V-shaped notch on the underside in the middle of the underside so that all you had to do was place a dowel in the notch and lift the plane up to see how it balanced I notice in the photo (with the wing off) that the notch is missing but it was there on the original part and centred on the underside of the support This plane flew so well that in a stiffer breeze it could even be hovered The tail is not bodged and is original as it did have these large curved edges I have a couple of pics somewhere and will look them out and upload them to let you see Great to see this lovely model again after so long Quote Link to comment Share on other sites More sharing options...
PIlot Error 2 Posted November 14, 2017 Share Posted November 14, 2017 Hi there..I know this post is rather old but wonder if you are now sorted as I have just bought an untouched pat French bucker jungmann at a swap meet with a plan.
