Thread: What RTF trainer plane would you recommend for a newbie.

Hi Connor

I have just started a series of articles, starting January's RCME (out now) on learning to fly. Might be worth a read before finalising your Christmas present wish list. I think you need to decide whether electric or IC before buying a model.

I'm so pleased you added the last sentence. I was just about to rush out with the vac and the duster!

Having had another play today, I have realised that with moving F1 forward, the battery fits easily between F1 and F2. You do not need to make F2 thinner.

I'm in the process of building mine, just being doing the fuz this week, and I made a ply F2 former and had to widen it a bit to fit the same Overlander battery. It was already thinner than the one on the plans, so each side was reduced to 8mm. I have moved the motor mount forward so I do not need the spacer mount. I was thinking of putting the esc under the battery tray, and perhaps leaving a portion of the rear fuz base open near the tail to get an airflow right through the frame.
 
I have managed to make the tail section detachable, using the same system Seagull use on their trainers - 2 bolts accessed from underneath. This should make covering easier, and rebuilding (almost a certainty!!!) somewhat easier.
 
Next job is the front hatch, I am trying to simplify this a bit, and reduce weight.

Thread: Transferring Plans Onto Balsa

However, ive always had in the back of my mind a conversation I once had with the zerox engineer at my old workplace. He told me that although a photocopy may look an exact replica in actual fact the reproduction image is slightly out to the original. which wouldn't be good for model making
 
Photocopiers do reduce by 1 or 2%. However, computer scanners do not, and they will give exact 100% copies (at least my Canon does).
 
Did you know you can print onto tracing paper very effectively? This makes it easy to line up the parts to be cut out exactly on the wood to get the edge of the wood or the grain right. You can also check the accuracy of the scanner this way too.

Hi Myron
 
Thanks for that. I am going to use the profile, but overlap the 3/32 sheeting onto the leading edge profile, and sand down the edge to the LE profile.
 
I've checked the dihedral braces. I think you are right here. I measured the angle on the plan and it is 3.1 degrees. This will give a dihedral of 1.7inches if my maths is right. The angle needs to be 3.6 degrees to give a 2 degree dihedral. (Those digital angle measuring tools are brilliant!)
 
I also notice the spacing of the wing ribs is anything but even. It varies from 72 to 75mm. You would think this would be easy to draw up. I cut a whole load of balsa webs all to the same size, and then had to trim them individually. Hey ho.

Oh right Freeatlast, you haven't just got out of Jail then

During the last few years of work, it felt like jail!
 
Will do the profile as you suggest. More or less a beginner, have just passed my BMFA "A", though reasonably comfortable with the building.
 
At the moment just making the wing template and have discovered the leading edge profile I bought is 3mm undersize. Aaaaaargh!

Hi Freeatlast ( from what? - the mind boggles)
 
Freedom from having to work for a living. Retirement means I can do what I want, when I want......within reason......
 
I did notice on the plan that you do not appear to be able to remove the front hatch because of the cockpit.

Hi Colin
 
I am just starting to build mine, I may be some time!
 
I too have chosen to build the electric version and also am going to use the Emax 2826. I am looking at a couple of changes, a fixed undercarriage instead of the wing bands, possibly using wing bolts instead of bands, and lowering the top of the rear fus as it looks a bit out of proportion.
 
I know about the wing dimension problem, are there any other problems you found when building it?
