The real T28's nose gear wheel well goes well back into the wing center section. It actually butts up to the mains. The result is a wing with almost no meat in the center section.

Status: offline 		Hey facmasterpieces that looks really good . I should get my 1/6 T28 back out. I started the wings but that is as far as i got as i need to buy the retracts and wasn't sure what to buy (85* on wings and 105* on nose i think).
Is it red or orange that you used on the nose and wings?

Status: offline 		hello gentleman!i have just shot the flat clear over her! now she´s wheathered and ready to final installation. thanks for the nice comments!
the color is red, but almost orange, i didn´t have the right colours, so i "guessed" as this isn´t a scale affair, i took some liberties here and there.
as for dihedral, it´s stock, i just have changed the t/e thinckness of all tail surfaces, other than that, it´s following the plans!
more pics very soon!

Status: offline 		Hey T-28 builders, I have a question, I have built the Pica 1/5 scale using a G23 engine. I think the plane flies tail heavy, their plans show the balance point at about 5-1/4" back, this is more than 30% of the cord, what have you experienced?

Status: offline 		It's been a number of years since I built mine, but I'll dig out my CG gauge tonight and check it for you - 5 1/4" does sound about right. I put a Brison 2.4 in mine and it doesn't seem to fly tail heavy at all. You might try adding just a bit of nose weight and see if it helps. Did you double check to make sure your engine is aligned with the thrust line and not pointing up a little bit? Mine flew off the board with no trim adjustments and is a smooth, stable plane with a LONG glide slope. You may just want to go through your incidence/balance/thrust angle settings and see if you can find one that is slightly out of kilter.

Did the G23 provide enough power? seems to be a bit small for that size T28.

I have that kit and the engine and haven't built it because I thought the power was lacking.

Thanks

Status: offline 		It flies ok. very much like scale, it can certainly take a larger motor but I like the way it flies, you might try the new G26. You also need a heavy engine in order to balance.

Status: offline 		I Flew mine for many years with a Super Tiger 2500 in the nose. It weighed I think 14 pounds. The G26 should be plenty of power for this plane. Remember to use about 10-15 degrees of flaps for take off. this will help the plane rotate from a negative angle of atack of the wing when sitting on it's wheels. the full size aircraft also used take off flaps for the same purpose. The plane is a joy to fly. I am now finishing one of my dream planes. a Byron T-28. At 98" wing span it should be even easier to fly , if that's posible. Iordered it from Iron Bay as soon as I found out they had brought the plane back into production. Saw one fly a year ago and WOW!

I have the 1/6 version of the T-28 and need the canopy desperately, anyone have a lead on where to get one?
