Perfect Decorative Trim on ARFs

How do ARF manufacturers so perfectly cut and apply large pieces of plastic covering for decorative trim on our models? They often wrap around compound surfaces, so I don't think they are done with...

I don't know what the AUW is for this model. I only have a 16 oz. food scale at home. I know that the weight of only the covered wood was 13 oz. I'm guessing my flying weight is around 28-30 oz. My...

Hobbyking Laser-Cut Big Stick kit

I totaled out my Sig Wonder this summer. All of the parts seemed to be recyclable except for the receiver and one servo. I decided to build the Hobbyking Laser-Cut Big Stick for only $30 to replace...

P-51 conversion has tip stall problem.

I converted to electric a Sig P-51 kit that is now discontinued. I believe it was intended for about a .15 glow engine. It is now powered by a 35-42, 1250kV brushless running on a 3-cell, 3000mAh...

I don't think you will need to add carbon fiber. In my experience the wing is the least likely part of the plane to be crash damaged. Other than knocking the firewall out, the most common crash...

Hi Gramps,

I guess the battery never had a chance to go up in flames because it was instantly and completely destroyed. The motor wires to the ESC were presumably cut by the prop. The BEC had...

That certainly is a nice smooth runway, but I think the FAA has some serious issues with you guys flying RC at or even near a real airport.

What does motor downthrust do?

Motor downthrust is actually an old free flight building technique that causes a modestly powered model to gradually climb. It does not hold the nose down as is commonly believed. On the contrary,...

Sig Hummer + NTM 28-36 3000kv = 100mph???

Jasmine2501,

Did you ever get a doppler reading on your Hummer? If so, did you fly it without landing gear? Have you run it on 4S?

I think my balsa planes are often more repairable. I admire your determination, but for me it would be the trash can. I'll follow this thread to see what happens. Good luck.
