Foamboard dlgs

[flyboa]

I prefer the 1.5m for all around performance but the 1m can be fun also. Electronic packages for 7 more planes plus extra servos.

 

[bracesport]

what Rx are you using?

 

[flyboa]

@bracesport I use a variety of Spektrum 4ch and 6ch receivers.

 

[flyboa]

Finished the 1m DLG . AUW 110g with three HK5330 servos and a 1s 150mA battery.

 

[bracesport]

@flyboa - nice - some flying followed by a barbeque? You are setting records with the weight levels! Also, it looks like you might be on a 'bus' system for the wiring?

 

[flyboa]

@bracesport No bus system used. I have paralled the the power lines on some of my receivers which might look like a bus system. A 3ch setup only needs 5 wires connected to the rx. 3 signal and power(+ & -) then tap off the battery and parallel to each servo.

Some ppl use seperate power packs to run their receivers and isolate them from faulty servos that might cause a brown out (loss of rx power).

Before my maiden I need to program flaperons and move the CG forward a little.

 

[flyboa]

Maiden went well. No trimming needed and CG was fine.

 

[rockyboy]

She looks great! Congrats!

 

[bracesport]

@flyboa - what is the chord on this one?

 

[flyboa]

@bracesport cord is 145mm. A bit longer than the 1m Hawk DLG is used as a guide.

 

[flyboa]

@bracesport Morning flight. No thermals yet but it is ready.

 

[bracesport]

@flyboa - as always your ships fly well - love the catch!

 

[flyboa]

@bracesport I had a wing fold on a 188g 1.5m. It had some creases but overall looked good. Decided to put it on a 140g ship and see if it would fly. It worked fine.

I think the original failure was due to high humidity, too much dihedral, and weight of the plane.

 

[flyboa]

@bracesport I made another 1m bird today. Used an old UMX receiver with rudder/elevator only. A bit more dihedral and a forward CG for this one to fly nice.

 

[bracesport]

I am back from a business trip so I should get my wing sorted this week!

 

[flyboa]

Maidened a new 3ch 1.5m this morning. Elevator spring was too weak. AUW 150g. I ordered some 50mm black PVC shrink tubing but it is coming from China so I ordered red that got here in 2 days.


@bracesport My next wing is going to incorporate more top camber like your wing.

 

[bracesport]

@flyboa - V nice as always - once I sand the leading edge on Thursday I will take a nice shot of the root chord cross-section - undoubtedly my ship will be a rock compared to yours, but I am aiming for the slope (but will still try a wing launch)! I am interested to know how many functioning DLGs you have? I struggle with time available for building and flying, but over time, that will improve!

 

[flyboa]

@bracesport 10 ready to fly and 3 works in progress. Friends have given me a bunch of stuff over the years. Never know when it might come in handy. Mostly just buying DTFB and some balsa once in a while.

 

[bracesport]

I am just about to print some new control horns for the DLG ailerons - what is the standoff height you are using at the moment (marked 'x'x), and are you aligning the hole on the hinge centre(marked 'y')?

 

[flyboa]

7 or 8mm for stand off. Depends on servos arm and the deflection desired. I run very little deflection since the full span flaperons are very efficient and I don't program full flaps. Yes, hole centered on hinge line.
