Hi all again!

Just wanted to filll you in on some of the nuances with this plane.

So far, my Hyperion is holding up well. I plan on cutting up my cowl (I have been flying it without cutting the cowl which looks nice) to allow a lot more air through the motor box. After a 6 minute Hard flight, the motor comes down just about untouchably hot. That seems to be one of only 2 drawbacks so far-

The setup
Castle Ice 100
Hyperion LiFe, 3000mAh mounted via velcro under gas motor box for CG
Hyperion 4025-14 370KV motor
2 Spektrum a6030 Titanium Gear servos in ailerons - MPI 1.5 in aluminum arms
2 Hitec HS-5245 Digi MG mini servos on tail- MPI 1.5 inch arms
1 Power HD ds090m on rudder - 3 inch MPI aluminum arm connected to Dubro GS pull pull setup- servo mounted on lower half of battery tray, just under the wing spar tube (barely fits, mounted cables on underside of arm and had to trim bolts short
SmartFly Equalizer for elevator sync
2 6s batteries so far, one 3 season old Hyperion 25c and one new Turnigy 6s- almost the same weight. I am afraid of going higher 'C' rating due to motor heat- will see how cutting the cowl works out cooling wise.

All the work for relocating CG on 6s and I am still shy of where I want to be. The only thing left I can do is cut the motor screws short and make them flush with the blind nuts so as to put the battery ON THE FIREWALL... May try the heavier Turnigy/Zippy 5800MAH 6s batteries if motor cooling allows.

I may consider going the Hacker a50 route- it is a heavier motor with higher KV.

I have heard nothing but good things about this motor and I think that this will swing 19x10 all day long without overheating. Let me know what you guys think!

Re: Funtana 125_Assembly, Electric Powered

guys,, i am currently in the final stages of the funtana build.. I noticed that
1- the pushrods are quit short..
2- the clevis hole is too small and will not thread into the pushrod.. do i drill the clevis to enlarge the hole or did i get the wrong size clevis..

Thanks a million
