Magnus Build thread - TJIRC

[Rcdan12]

I believe my setup is in that power range. Haven't clocked it for speed yet though. Have a look at my video in this thread.

I've see that, definitely fairly quick! What motor/prop setup are you using?

It's a rather old Aveox F27 F5B with a 3.7:1 planetary. it's on 6S spinning an Aeronaut 15x13 prop.

Will kst x08 servos be fine for ailerons? X10 for flaps and a ds215 for the elevator? Any other suggestions?

We can order them for you, just drop us an email: contact@alofthobbies.com and we will get you going.

We can order pretty much any spare parts for any models we currently sell, and sometimes for models we do not sell.

Is this a common occurrence for carbon planes? This happened on a gentle landing on a soft grassy soccer field.

Suggestions for repair? Just epoxy the hell out it?

The epoxy has already failed, Justin. More won't help.

Rough it up and use thick Cyano, but get it straight and clamp it between two straight rulers or pieces of wood to avoid waves.

Doc.

Not normal at all. Would you like a new replacement part? Go ahead and repair that one for now, but we can order up a replacement ASAP.

For repairs I would suggest using a structural epoxy. CA will offer greatly reduced glue strength in this application. Sourcing a thin structural adhesive can be a little tricky though, not going to find it locally. Sand back some of the old material first.

Thought about that. I epoxied the tail on though, and I'm worried that if I dig and grind it all out, the seat for the tail will no longer be true. There are a couple of spots on the non-damaged side of the elevator that I see the white epoxy missing from the TE, so this one may have been made with a poor mix? Just grabbed a bottle of extra thick Smith CA, so will give that a go. Worse comes to worse I'll cut it off and make a balsa replacement.

@Wayne guessing there's no ETA on the next shipment from TJIRC? Safe to assume the tariffs will cause an overall increase in the price of our toys?

 

[Wayne]

Should be getting a shipment very soon, they are a little behind right now. Yeah, such is life with Tariffs. I think you will see an increase in much of the hobby as so much comes from China.

My original thought was to fill the void between the old epoxy with the same epoxy I used on the control horns, then a bead of thin CA along the TE. We'll see how much of a mess I make with it.
