Modifications and History
TJ2 is sprayed in the Maclaren Mercedes F1 team colors, and powered by Permax
480. It appeared in RC Model World mag in the spring.
TJ4 (Blue Shark) is also Permax 480 powered.
Rounded -off elevons, servo and control rod under wing protector pods,
one-piece canopy, velcro battery retention system, dual conversion receiver,
and bright dayglo orientation markings. It goes like stink! It's the 2nd
fastest plane in my club...I also own the fastest ! (A Magnum IC with tuned
One - piece canopy.
Velcro straps (& unseen pad) for battery retention.
Chamfered-off elevon tips (note shape !)
Under wing servo-arm protection pods.
High - visibility dayglo red under wing trim for orientation.
High - visibility dayglo red trim on upper leading edges and tail leading
edges for high-speed turn orientation.
All body joins, leading & surface edges are covered in Diamond tape for
perfect aerodynamic airflow.
GWS 8 channel dual conversion receiver.
It flies (& glides) like a dream...or maybe a nightmare for my club
If you land on rougher grass or overshoot the strip a bit and land in the
rough, those servo arms & rods get ripped off like they are made of
candy ! The rounded elevons also help to avoid snagging in long grass, which
can lead to the plane cart wheeling or spinning.
It happened twice, and you have to have the pods over shrouding the control
rod length which isn't quite straight on to the airflow...but don't worry,
they are very slippery indeed.
