RE: New bird
Very interesting, and may be a way to use up some of my extra wings. It looks like the top wing is a thicker airfoil than the bottom. Is this true or just camera angle? Thanks and Good Job.
Sincerely,
Richard

RE: New bird
Ok after a week of getting the P-47 up to 1st flight mode[8D], Got back into the Corrowot Bipe. Some more build pics. The inside of the fuse has been boxed up with ply for the wing mounts. The engine bay will need some more and the UC will have to be raised or a 3 blade prop. She's heavy...But built like a brick shizen house.

RE: New bird
Ok an update. Ran the motor last week and could'nt keep it running at idle carby problems. Tried another type and she wont rev past 5k rpm, will with a smaller prop but this is a big bird the comp is too low as this is one of the single ring blower motors with no grunt. ordered a new 30cc motor today. The Ryobi will power something else like a profile 3D

RE: New bird
Ok got back to the bird this week.
New engine fitted but now too light on the nose, The Ryobi is twice the weight as the new one. Just have to plumb up the fuel refit the wings, stop the fuse from flexing at the firewall and hopefully running this week end.

RE: New bird
Tried to balance the Bipe tonight. need 1 starter battery in the nose!!!over a kilo..
Stripped her down and redrilled the fuse to bring the wings back 2", checked twice and still stuffed up one side by 1/2' The joining tube is a bit out of alignment. Had refill the hole and trying again in the morning.

RE: New bird
Update..Still didnt get the hole for the tube correct..A bit of filing and grinding. Refitted the wings didnt shift the upper wing and the CG is about right..
Ran the new engine today. love gassers, low stable idle and a clean prop wash( no metho). Ran it for 10 mins or so. My 1st spark engine plane.
Just have to fir the top deck on.
Pretty?? No way...

RE: New bird
Nice plane, jaav . Not to many try the biplane; a lot of added work, plus a crash involves more repairs. I love them. I totaled my SPAD biplane a few months ago. I never had one bad landing with it, except the last one when it got WAY ahead of me. I'm drawing up the plans for my next one. Keep up the good work and show us the flying photos.

RE: New bird
Well shes ready!!!!!!
changed all the wing mounting bots to quality 4mm with nylocs, Made a 2 piece deck cover which slides in a channel to lock in.
maiden tomorrow Wind or no wind. With this sort of weight i dont think wind is going to be a problem..

RE: New bird
Well she flew[X(]......very 1930's scale....
put her on the scales after the 1st flight and she was 7.2 kgs (15.8 lbs) [:-]
Under powered!!! needs reproping or a 50cc[>:]
this photo is a pic of the sliding deck cover that fills in the old wing cutout. just 4 strips of 90 deg edging, slide the back section in 1st then the front in 2nd then tuck the end of the front section into the rear rails...simple and acess is quick..
unbolting the top wing I found that I left one of the struts unbolted......OOps

RE: New bird
Did some work on her today.. New prop 18x6 (the old one was 16x8) ran the engine, after last weeks long run she re-sponded to the tuning much better, no more stumbling at idle. lost 600RPM with this prop and a lot more pull...
As for the glide like a brick with no power, modified the horizontal stab, added 110mm to the ends.
Just wish the wind will drop, Its been over 20 kts and gusting to 30 for the last 3 days.

RE: New bird
Hi jaav
Nice videos. Flying in high wind can be a lot of fun. Since landings can be a problem, I usually make many of them each flight. If one landing is particularly difficult, frequently I will take it up immediately again to keep my fear from overpowering me.

RE: New bird
His girl has new been broken down for thewings and engine, The fuse has too many breaks in it from the engine. It wasnt designed for gas 26. only a 4s 91. The fuse was basicaly tearing apart. Going to be turned into a profile bird.
