Greatplanes Cherokee 40 ARF ( SAITO FA-80 )

......here is the maiden flight of my GreatPlanes Cherokee 40 ARF. with Saito FA-80 4-stroke engine.
I used an APC 12x8. Glowplug is an O.S. type #F & fuel is as always CoolPower 15%N-18% oil. Check the assembly thread here : http://www.rcuniverse.com/forum/fb.asp?m=10419268
All went smooth but the wind was arround 7knots....

The only negative was the aftermarket muffler.....it came loose on the maiden flight after 3-4 minutes in the air....
And it came loose with only the exhaust fuel line ( pressure line ) keeping it from falling-off.....BUT the engine didn't die, she kept runnin' and eventually i land it safely, without using the flaps. I tried the stall characteristics and without flaps you can use your ailerons from keeping the wing horizontal, while the airplane looses altitude gradually.

If you then use flaps @ 30deg. as mine are set, then you have a *glider-like* airframe,no kidding!!!
It is unpossible to stall it.....

The Saito FA-80 @ APC 12x8 gives the airframe very very nice power. At WOT the airframe can climb vertically effortlessly!

It seems you have too much elevator throw. Reduce the throw or add exponential on the transmitter.

@peterlution actually no. not too much throw. it was the maiden flight and it was untrimmed.

@dreamwisperer Hey, go electric. It's clean and not that expensive. Recently I build my own with electric configuration. Check out my video on YouTube. Search for peterlution.

[dreamwisperer]

@peterlution no, no electric.

[dreamwisperer]

@71259mark I didn't install it on purpose....in order to prevent a possible overheating. Ofcourse during the next flights....

@dreamwisperer Where's the cowling?

@emiliomahias Guys, watch my t-shirt ...... the wind that day was awefull, despite the *good* weather forecast!

[dreamwisperer]

@emiliomahias I think that i've set my flaps at either 30 or 40 degrees....i am going to lower though to 20 degrees of defflection!

[dreamwisperer]

@emiliomahias Actually the engine is not that big...during take off i had problems with the direction of the wind....the Cherokee took-off heading to a direction that was vertical to the direction of the wind....i know, bad decision....but the other guys where sitting at the wrong position so i had no choice....anyway, everything went ok....

good video, really long =P!!! I think the engine its just too big for the plane...but it sounds great, got to love four stroke engines, make new videos i will be specting them, good luck
