110" Extreme Flight Yak for IMAC

[xtra330]

lol - thanks Dan!

just an update on the throws I had settled in on;

Pattern mode (including snaps) -
ailerons - 27 deg up/down
elevator - 13 deg up/down
rudder - whatever it takes to hold knife edge at 3/4 throttle

Roller mode
ailerons - 7 deg up/down
elevator - 8 deg up/down
rudder - whatever it takes to climb 1/4 loop at knife edge at 3/4 throttle setting

Spin mode
ailerons - 20 deg up/down
elevator - 22 deg up....18 deg down
rudder - just slightly more than pattern rate rudder

Hammer mode
same as pattern mode - except for rudder throw - I have all that I can get for this mode.

I had went out today and made some minor tweaks - one thing that really helped out was incresasing the tension on my after markert springs in the transmitter. I had also played with the expo options....but resorted back the 'normal' settiing. By the end of the day - I was a happy a camper.

Hi Joe,

If I might ask.

Have you tried a 3 blade yet?

I assume your KS pipes are the 1060s. What length headers are you using?

Many thanks,

Branwell

hi there -

nope, I havent tried the three blade...28-10 Mej and thats it. I want to try the 28-12 mej and the 26-12 three blade mej.....but i just cant seem to come off the hip for playing with props...if i come across somebody with the props at the field or contest - i will try them. Days of paying top dollar for props for one or two go rounds is not for me..lol

I am using standard length headers that DA sends with these 1060 pipes/airplane combo....with about a 1/4" gap in the teflon coupler....I have no throttle curve and see no need for one.... I think this combo is working really working well.

I am still rich on the needles and just slowly turning the high needle in until the 'messiness' on the botom of the plane lessens a bit more....not sure of the RPM's...but i can tell you the vertical is insane!

I have heard too many responses about the 25-12 meg not doing anything on this plane...given, I havent witnessed it, so I cant comment....but the 28-10 does get noisy from time to time! I think the 26-12 (3 blade) would be choice for this combo? or even the 28-12 Mej (2 blade)?

thoughts?

Hi Joe,

The 25-12S and 26 x 12N 3 blade props will likely run lower RPMs to the MEj 28-10. If this is so, the headers will probably need to be lengthened for best performance and throttle response.

Lucky for me, I stumbled upon both props really cheap second hand, and just happen to put 1060's on the DA in my Yak

I'll let you know how they work out later this week. I hear as long as the plane is moving, they are not to bad at all, i.e. the up lines are still strong. Where they fall down is in slow speed maneuvers like 3D.

Given my flying is about 50% 3D, its unlikely I will love either one, so if you want to borrow them after, you are welcome.

There is something called a Biela 26-10 3 blade that is also on my list of props to try. Seems to get good reviews and is said to have great downline breaking, which none of the 12" pitch 2 blade props I have tried so far excel at.

wow! that would be fantastic!

I appreciate the offer - just let me know the shipping and I will help out with that part of it. I would really like to see what they will do on this plane....please keep me posted on your findings!

Im not really looking to experiment with header lengths, etc....so i will be interested to see how they do with a 'stock' set up.

Thanks again!!

Hey Joe ,, in your "roller rate" you just pin the aileron and work the circle wth the rudder and elevator,, I will be flying the Mocksville contest Aug1-2 in Intermediatte and I am getting ready to start practicing rollers.

[xtra330]

actually, no.

Im not a fan of doing rollers that way. I like to have a bit of extra aileron in case I have to speed up the roll rate...whether its windy conditions, falling behind in the roller, or...if i get in trouble and need to 'hurry' the roll rate.

7 deg doesnt sound like alot...but it actually has a comfortable speed...it could actually be slowed down a bit more, if you like to peg the aileron.

This plane really likes to be steered around with the rudder - and use it the most.

see ya at Mocksville!!

Yeh I would feel the same way,, I don't want to me using "all" the throws I have in any manuever , especially when you have the OH CHIT moments when you need to adjust something,
