OPJOSE,
I know you posted 2 or 3 years ago on this forum (so I'm not sure if you even check this anymore), but I was curious if you could tell me more about how your LA46 worked out in the Model Tech Extra 300? I actually just finished building that exact combination and was wondering if there is anything important I need to know before flying it. It seems like it should be pretty quick. Have you ever clocked yours or do you have an idea of how fast it'll go? The balancing worked out almost perfect and I'm excited to get it in the air.
After MANY flights the triangle stock holding the motor mount to the firewall came loose. Of course I am just a BIT hard on this plane... heh...
Fortunately the design is such that the airplane continued to fly this way and I only noticed it as I was putting the plane away for the day.
A little epoxy and it was airworthy again. Consider going over the motor mount area with CA and then putting more expoxy over after the CA has dried.
My little Model Tech has hundreds of flights on it now and still going very strong. The only deadstick I've had with it was because I was having too much fun and forgot to bring it down once the timer went off.
I've never clocked the speed of the plane but it is indeed very quick.
The worst thing about this plane is that the wheels are fairly small for grass takeoffs/landings, so if you'll be flying/landing from grass, change out the wheels. I punctured the wings and ripped out the gear once during a grass landing. Again this was an easy fix and the plane still looks like new.
It lands more slowly than you would expect, and given the engine combo you are using, you may find yourself coming in too hot.
Don't be afraid to let it slow down for landings. Once you are used to it's glide slope angle you'll be greasing them all in.
Other than that, you'll have a blast with this plane. It's a keeper.
