The Magic of that Maiden Flight !

A model's maiden flight - magical with exhilaration, or maybe diabolical with palpitation.

Whichever it's like for you - brown trousers and bicycle clips, or that winning moment on checking your lottery numbers - the maiden flight is going to be a whole lot easier - and maybe very much more successful in its outcome - if you can take away some of that pre-maiden flight stress and pressure.

But how?

Simple -

- we all know that in 'the heat of the moment', it's so easy to forget some important things you should have checked - so, why burden yourself with trying to remember it all.

Use a brief checklist - of just a few vital things.

I'm talking vital things, which if they're wrong, are at the very least likely to give your wallet some pretty serious palpitations.

So, a simple checklist of those vital items - items which you know, if you fail to get them right, then even your bravest face on the outcome is unlikely to promote the claim: 'magic with exhilaration' !

Obviously, there are going to be all the usual pre-flight checks which you can probably do with your eyes closed and your transmitter tied behind your back - those you can probably do almost subconsciously.


But it's the pre-maiden flight checks which are specific to the fact that this is, as yet, an untried airframe and an untried setup.

These need your focused attention - and, of course, to be sure you cover them all - this is where the situation can benefit from using an 'aide memoir'.

Below is a short list of some main points to check and, of course, you may wish to add items which are specific to your model. Or items you just think should be included in the list, such as checking for warps, or that the plane is laterally balanced.

If you think this check list a helpful idea, then go ahead and print out a few copies for you flight box -

- or use it as the basis for creating your own list.

Maiden Flight Checklist

1. To start with there's the centre of gravity check - pretty essential that this is correct.
Now, of course, you did remember to note where the manufacturer (or plan) said
the C of G should be.

2. Security of flight and control surfaces - check the wings, tailplane and fin are all
firmly attached
- though I know you're not the sort to forget to glue that tailplane or
fin in position. Also check the ailerons, elevator and rudder are all secured by
whatever means and that they don't just pull off.

3. Engine / Motor and propeller - check they are all tightly fastened in place.

4. Undercarriage secure? Gently push the plane along the ground - does it track
straight? If not, something is out of alignment or there's a binding wheel. Though it
could, of course, just be asymmetric encounters with worm casts !

5. Battery secure and not going to slide free. Battery in good state of charge.

6. Correct model selected on transmitter. Though, is anyone still using 35Meg?

7. With plane secure, try low throttle.
If electric, is the motor turning the correct way ie. air being blown rearwards.
Switch off the transmitter - does the failsafe work correctly - does it cut the
motor/engine.

8. Radio range check.


9. Check of control throws and that direction of control surface movements are
correct - indeed check the correct surface is moving and you've not got plugs in
wrong sockets. Easy to do if you've elevons or V tail setups.
Exponential, if set up, is it working correctly - not set to make things more twitchy.
Rates, if opted for, are they working correctly and you know which switch or
switches.

10. You may want to have someone help with this part. Hold each control surface as
you command the servo to move it and check that with slight resistance applied,
that the surface still moves. Servos can be faulty by way of being able to move an
unloaded aileron or elevator, but when a flight load is applied the power isn't there
to give the desired deflection.
And check control surfaces centre correctly.

11. (other items I'd like to check... if I could remember them):
