Not sure what to do about that, but it's pretty disappointing.

Hey Jan, could you please tell me what you used to make the two long raised panels that are on the top of your rear bulkhead seen in the second picture on here? i like it lot.






Then some photo's at the field,

Here the mechanics and the fuselage,



Yes it fits



And just some nice photo's





Later this day I did the exhaust area,



Panel lines, weathering etc still to come,

Then a photo of my fleet, a Hughes tow defender with a trex 500 inside,
Then a stock Align 600 ESP, and the apache mechanics 600 size and fuselage.



It was finely a nice day to take the toys to the field

Kind regards,

Jan,[/QUOTE]

I have used a 450 main and just glued the crown gear with thin CA.


Jan, did you reuse the lock pin and drill a hole in the 450 shaft, and if so, what size bit did you use?
thanks

Hi Buddy,

No I was not able to get a 2mm drill in this metal so I glued it with thin CA and that is holding.

At least the front crown gear from Align melted and no problem at all with the new tail assembly and the SM gears.

Of course it has not many hours (25 minutes I guess) but it feels very tight.

Jan,

i just track them in pairs...remove 2 blades, track...put them back on and remove the other 2, marking where they are suppose to be, track again, now put the first pair on to make it complete, if you still have tracking, change the pitch rods in pairs..worked for me several times

succes!

Hello all,

I have flown the Apache today it was a bit dark but I was eager to know if the tail was holding now and what the temp of the gears where.

My buddy lend me his laser temperature gun so that easy to do.

I noticed that the head-speed of 1250 rpm was to low to have real power on the tail with this X rotor head.
So Its now 1350 rpm and the tail is responding crisp and just feeling good.

The temp on the gears is between 30 and 35 degree with 18 degree outside temperature no problem.
The Motor are 45 degree, battery's 43 degree (5% left) forgot the timer.
ESC 42 degree so sound all right for me.

Regards,

Jan,

Definitely a bubble. It's extremely obvious and the other 3 blades are smooth as glass. They are sending me a new pair.
