Misceleanous / once upon a time

and was dealing with this beast :)

How to... / servo size vs model size

I would like to do it right way this time - prepared to spend some extra cash
on servos.
So, the question is what servos to choose to 3m Condor ?
I originally planned to use Hitec HS85BB/MG (MG for flaps),
but now worried if those will be powerful enough (3kg/cm).

Any thoughts/theories are welcome.

Thermal / Flat field / good 2.5m+ sailplane - which one ?

well, at least MACI provides insurance for FPV now.

7) Visual Contact / Competent Observer
Article 166(3) of the Air Navigation Order (which forms UK law) stipulates that the person in charge of a small unmanned aircraft must maintain direct unaided visual contact at all times for the purposes of collision avoidance. In practice this means that two people must participate and the pilot in charge must be the person with his eyes on the model. The FPV pilot may have control for the entire flight, if it is safe to do so, however the person in charge must be able to take over instantly if required.
Exceptions: Models under 1.8kg AUW (including fuel, if relevant) may be exempt from article 166(3) where the model meets certain criteria and specific FPV UK flying procedures are followed - including a Competent Observer.


3. Competent Observer
A ‘competent observer’ is defined as a trained and competent person designated by the person in charge of the aircraft who, by direct unaided visual observation of the aircraft, assists the person in charge with the safe conduct of the flight.

no requirement to use buddy box, just have an observer by your side.

Just got a document stating the position of MACI in regard of FPV.


First Person View R/C will be a legal and recognised aspect of model flying and as such is covered by the MACI Insurance policy but ONLY where the following conditions are applied:
• The activity is solely for 'sport and recreation' purposes.
• Two MACI member pilots must take part.
• A Buddy Box system must be employed.
• The pilot in charge must operate the master transmitter.
• The pilot in charge must not wear the headset or view a screen.
• The aircraft remains within the natural unaided visual range of the pilot in charge.
• Reliable operation of the Buddy Box is established.
• A clear handover protocol is established.
• The pilot in charge is solely responsible for the safety of the flight.
• The model weight shall be limited to a maximum of 5 kg.
• The model should have the insurance number of the planes owner.
These operating conditions very clearly place the legal responsibility for the safety of the flight on the pilot in charge, additionally the responsibility for the legality of the transmitting/receiving equipment utilised also rests with the pilot in charge.

For me this is not what the rest of the world is calling FPV.

do you think you'll go with this one?

yes, I'll stick with this one.... if I decide to (re)convert the Condor back from being electric.
