Dade City? I don't know....I might be able to go. I may have to ride though. I am training for a 200 mile bicycle ride.

Diamond D47's in Bipe


Has anyone used the D47's in the Bipe? I've run into a little problem in the lower wing. The short stringer that goes between the W1A ribs and supports the lower wing upper deck D3 doesn't seem to allow enough clearance for the aileron servo to sit in it's pocket. I think I understand that the D47's require the use of the small plywood spacers but this interference doesn't feel right. The servo stands proud of the wing about 1/8". Anyone else run into this?

Are you using two of the plywood adapters? You may need to trim the stringer or add a shim under the plywood adapter. The D47 is a great servo, it's just a little tall.

I think I just trim the stringer.

Thanks James


The gap is more than 2 shims worth. I can certainly trim/remove the stringer though. How do the HS45's fit? If they are a better fit I can always save the 47's for my 3DX.

The HS45 requires a lot of triming.

Got it all sorted out I think. Pulled to covering off, trimmed the spar and recovered. Looks pretty good if I dare say so. Worth noting though if anyone plans on using the D47's.

Now all I need is some warm weather! It's 12 F here right now!

HI ERIC,
I still haven't been able to maiden mine either. The weather is horrible in CT. I built 4 new planes this winter, and I'm on my fifth. They all need there maiden. I have one cheep, profile Katana with skis that I fly in the winter.

Ok I'm back on track too! Got the Wb1 rib moved over where it should have been. I plan on using the AR6100 spektrum I'm hoping I won't need to extend the servo leads.
Should I run a Y for the ailerons?

Thanks to James for sending two new ribs to make the repair

I used a Hitec mini receiver, that allows you to plug the second aileron servo into channel 5. eliminating the need for a y harness. your spectrum radio should allow the same application.

I set my biplanes up with channel 5 also. On the spectrum radio I program for flaparons and disable the flap switch.

Biplane final assembly


Be sure when you mount the wing a tail section on the biplane that the tail section is mounted all the way to the end of the fuselage stick. The wing should be as far forward as possible.

Finely got the Bipe together! Now if the weather will clear I have three Bipe's to maiden.

As a minimum, if you can make it longer, the plane will fly better.

I had my maiden flight this morning, I still need to change a couple of things. I swaped out the motor(I cooked the old one on the bench ouch), the new motor will take a 3 cell 600mah pack. but its 1/2 the weight of the shulman fury so I need to add a little nose weight. even though she was a little tail heavy. I still ran out bolth battery packs and had 5 or 6 landings. Once this thing is dialed in its going to be awsome. It's also very fast with the dualsky xm2812ca-33 motor and 3 cell 600mah 20c pack.
