The CAP 10 sports aircraft, produced in France by Mudry, first flew in 1968. Production continued through 2007. CAP stands for Constructions Aeronautiques Parisiennes.
The fuselage of the CAP 10 is hand made from wood. Its framing consists of triangles linked to formers joined by gussets over which planking is applied. The wooden wing is of conventional construction and is shaped to a NACA 23010 air foil. Its shape is aerodynamic with low drag while being responsive to aerobatic maneuvers.
Flying the CAP 10
The 180 h.p. engine delivers reasonable acceleration and climb, but nothing that could be described as neck-snapping. However, the aircraft is capable of performing most aerobatics with hardly any loss of altitude.
The cockpit of the CAP 10 gives you some clues to its aerobatic heritage. It has a no-nonsense, highly functional design. Controls are logical and well placed. There are throttles placed on both sides of the cockpit, convenient for use with either hand. The stick is designed to facilitate positive control during high-g aerobatic maneuvers. Cockpit visibility is excellent for this type of aircraft, however ventilation can stand improvement.
The CAP 10 is easy to fly and does not exhibit its sporting heritage until asked to do so. Shooting touch and goes around the pattern, or flying short hops, will find a well mannered airplane. It has a nice glide rate and its controls have a good feel without being overly sensitive with the exception of the rudder.
It is when the CAP 10 is pushed hard that its aerobatic nature really shines. It’s rated at from + 6 to – 4.5g maneuvers. The zoom climb and ability to hold its speed is impressive. It will immediately snap roll in either direction with only a moderate touch of the stick. It will also stop rolling with the same precision. The rudder has extreme authority and is somewhat sensitive.
Stalls are sharp with a clean break, but it can drop a wing if one isn’t careful. Recovering from inside spins is normal except that it absolutely requires centering the ailerons for a smooth recovery. Inverted spins present no problems.
Other than a need to be aware of the extreme rudder authority, taking off is a breeze. You do need just a bit of rudder to keep the aircraft rolling straight down the runway.
Approaches are generally made with full flaps. The flaps will block some of the prop wash over the rudder and reduce some of its authority for landings. The landing gear have less spring than most aircraft.
The CAP 10 has been used as an aerobatic trainer for many years. Some of Europe’s top pilots started their training in one.
A total of over 300 CAP 10 airplanes were built, of which some 200 are still flying to date.
RC CAP 10
That’s Martin Rousseau with his RC CAP 10 built from a kit from MR Aerodesign. It has a wingspan of 80 in. and a length of 65 in. Recommended are 45cc to 55cc engines. Weight is about 15 lbs. .
The RC CAP 10 from VQ Model comes almost ready to fly (ARF). Wingspan is 59 in. and length is 47.5 in. It is made from balsa and ply and available in red, pink, or yellow color schemes. Power can come from from .61 to .75 two cycle or .90 four cycle engines or an 870 watt electric motor. Weight is around 7 lbs.
