Dear All,

finally got my Topstar-60 (essentially Phoenix clone of U-Can-Do 3D or Twist-3d) in the air today. I am using an OS 75AX on the same and it is currently installed inverted (Head downward) as per manual. Some one suggested to have the engine installed at atleast 90Deg as installing inverted gives performance issues. Is this true and what other problems can I have with the engine inverted?

Also, in my second flight I had a deadstick and landed calmly. Was this cut-off due to the inverted engine? I was at about 40% power at that time straight and level having just finished a roll.

Since I am one man team at field, taking the booster off once the engine has started is an issue. Am currently thinking of installing a four-stroke type remote igniter off the receiver battery which I will switch off once the engine is started.
