My Posts This: Topic  Forum		Hi all,
Inspired form the TwinnRex, i homebuilt a 450 size mechanic with T-Rex Parts and standard aluminium profiles.

I do the 4 degrees angle of the front and reax axels and i also use 3-blade heads. The mixer is from Twinnrex.

Actually i try to fit the body and, if time, i trim the heli with the TechLink software.

Greetings

Urs

My Posts This: Topic  Forum		@GyroFreak: looks good your twin! specially your passengers looks like they have fun.

@heli_madken: thanks, i have now a problem with my rear elevator servo. it collides with the rear tower of the body. maybe i have to cut a hole for the servo :-( but it's anyway a semiscale and not a scale heli.

greetings

My Posts This: Topic  Forum		Hi,

Have you thought about dropping the servo down, I know you havent got much space before you catch the mitre gear. The other alternative is to turn the servo through 90' horizontally which looks doable with a bit of trimming, I use that technique all the time to save space as you can see here -
