I test flew my New Delta on Sunday and while not fast as on a stand throttle pipe with the manifold way to long.

 

The plane flew very well and handles well great roll rate and smooth as can be in flight. Behaves better than most delta's with a small drop in high on tight turns.

 

Pics attached.

 

Will fit the full pipe and shorten the manifold for next time.

Its a lovely looking model, Andre.

 

It does look at ease in the air, even with the throttle at full bore. With the fully tuned pipe fitted it should eat up the sky rapidly.

After fitting a tuned pipe last week the engine was not running at full throttle. After much head scratching and testing and checking I finally established the pipe was throttling the engine. So I used a 50 sized pipe and he presto engine runs fine and full throttle found a few more rpm.

 

On launch on Sunday in the wind, it was very windy on Sunday, flew fine until opened her up down wind and man she was fast. After a few seconds herd and odd vibration and after slow her down noticed half the tail feathers missing.

 

It appears vibration at high speed is the culprit, will rebuild tail section and strong than before and fly again.

You speed demon, Andre.

 

Model looks like its been in a dogfight!
