RE: Extreme Flight 88" Yak - Build and Fly

Understood, but I disagree WRT weight , 6oz is a lot of weight... make it up elsewhere? - like single servos in the wings of a 104" bird (you'll need to remove original hard wood of inner/outer...

RE: Extreme Flight 88" Yak - Build and Fly

Personally, I would run just one 2S1P a123 cell in that bird, unregulated of course, switched to the DSS RX... So you want to do two batts and both switched to your (DSS?) RX? Of course if the one...

RE: Extreme Flight 88" Yak - Build and Fly

Sorry - I wasn't clear - I personally do not run dual 2S1P a123 cells with a PE - I run a single 2S1P a123 cell through a switch (obviously) to the DSS RX... Some guys insist on dual bats so the PE...

RE: Extreme Flight 88" Yak - Build and Fly

FWIW - I run a 22A w/the ES pipe (da50) and love its responsiveness at low end - rips a bit WOT, but you can't run WOT for more athan a few sec's unless in a good upline...

RE: Extreme Flight 88" Yak - Build and Fly

The most straightforward setup is (and I run this in 35% kits) is a single 2s1p a123 UNREGULATED (straight to the DSS RX) which provides 6.6 nominal and 2300AH of capacity (the larger digi servos...

Gentlemen, Thank you for the assurances. What would be most assuring is to hear from J David - I just now am seeing that he logged in here yesterday... Why would he not type in a quick note to me?...

Typical culprits are:
1. Elevator halves travel at different rates
2. Elevator halves don't stop at same deflection
3. Rudder trim too far off center
4. Horiz stab to rudder not 90 degrees

RE: mvvs 1.60 gasser carb #'s

Hello,

re: Aluminimum for a header - I use a MACS header (which is alu) and have no problem. These motors do run hot though, watch what you touch after a run.

Thanks again Dick - I will try the Skorepa 18x6, tach it and report back here - However, I cut the Macs header to 12CM because that is how long the steel one is: http://mvvs.nl/ (see petrol engines...

Hi,

I thought I read somewhere (can't recall now where) that the walbro on the 26 can be "bored out" (to ? - a larger diameter) for more power?
