I might try to make it down, don't think I'll fly, but I might come down to see how the competitions go. In-Laws are moving this weekend so I'll be up in Marion anyway. I'll have to check with the boss.

Come on to the Columbus IMAC. Should be a great turn out and hopefully I will actually get to practice some sequence flying this week. We shall see.

Looking forward to meeting you Chip.
Thanks for the frequency info. I'm all squared away now.

I hope the weather Gods are on our side this week. Memorial weekend typically is wet but our meterologist at work thinks it will be fine on Sat. and Sun, but it is still pretty early, and mother nature does as she pleases.

I have to do alittle mx on the Yak- tighten eng. mounts, rebalance prop. and install a instrumant panel but I should be good to go. Got my new hatch and canopy for the Katana so it will be less ugly than it is now too hehe...

looking forward to a fun weekend.

I have a prop question. I've been flying my yak with a 23x8 NX prop. I thought it was fairly stable in a torqueroll. Today I decided to try a 22x8 3W prop.

I swear it was more difficult to torqueroll, I couldn't get it locked in for nothing

Is it my imagination or does it make sense that the smaller prop would give me less control?

thanks
John

I have a question. how many of you guys are running an actual servo to control your choke? Because Tom at Wildhare recommends doing this, because you can operate the choke go figure, and kill the plane in the air if for some reason its on low throttle and wont quit. And IMAC recquires a wat to kill your plane in the air, if something happens. With this setup by Tom, it will kill 2 birds with 1 stone. Thanks!!

I prefer a fiber optic kill switch. A servo operated choke is nice, but is a tad bit heavier if you use a good servo... and, can often be a pain to install. It's usually quite crowded getting a servo and linkage to both the throttle and choke, and requires a much more "sturdy" mounting scenario for the servo than what you need for a FO kill. Mostly just a matter of preference and ease of install.

I used a opti kill whitch also. As far as operating the choke, I have a stick with a bit of wire on it, just reach in and flip it. The opti switch, IMHO, is the best way to go.

My 40% IMAC plane has a FO kill in it but its not requied by IMAC.

Agreed. Choke servo is not only more of a pain to install, but it also may not do you any good in the event of a RX failure, not that that would matter too much, but an out of control plane that goes in deadstick is likely to be a less costly crash. You have this feature with the Smartfly opti switch - if you have no rx signal, you have no engine.

not to mention trying to remember which diretion the switch goes to flip a choke servo... even tho the FO swirch needs a swich, the smart-fly has an led to let you know it's hot...

safety in starting... if receiver is not on the engine won't fire...

Does this type of thing actually happen in the real world?

ABSOLUTELY! Happens quite often. Has happened to me. All you need is for a throttle linkage to come unhooked, throttle servo to go bad, throttle servo arm to break, etc, and you have no control of the engine in the air.

If throttle is stuck at low/idle rpms, the engine could run a lot longer than your RX battery will. That's a disaster waiting to happen. ALL gas engines should have a means of shutting down from the TX. If you have a plane that's stuck idling, it could run 20, 30 minutes. Some big tanks will run 45 minutes. If it's your last flight of the day, you may not have 45 minutes left in your RX or TX battery.

I run a choke servo on all my gas set-ups. Very simple to do.
I was at the field this morning and a buddy of mine was flying his 40% godfrey Extra and his throttle servo stop working at wide open throttle and no means of shutting it down.

RCCATS has an electronic switch, which works off the transmitter. Only weighs 1/4-1/2 oz. I have one in my Yak & it works great.

Chill BARCC,

What ge stated was that you did require a firber optic kill switch... indeed you are required to be able to kill the engine SOMEWAY...

Either a choke servo, a fiber optic kill, some put a servo activating the manual ignition kill, heck some form of fancy dancy fuel filter with shut off could work...

But what Wayne intended you to read was that contrary to others that use the choke servo method, he uses the fiber optic kill... not the only way to do it, but his prefered way.

It's easy to misunderstand typed messages...

Visit http://www.smart-fly.com and select ignition kill switched to see the type I use but you DON'T have to select...

I use a choke servo - My ZDZ50 starts one flip -every time using the choke switch - the start up is very quick -even first flight of the day -no stopping and reaching under , etc.
as for weight - be serious - 2 ozs. I am still a 15 .25 lbs total
If you leave on hand at the tx you can hit the Rtx switch during choked BURP and it continues running.
also if you kill it after taxi back -using choke switch - next start is simply switch on --flip - run
simple- reliable - effective
PS if you wanted to you could set fail safe for choke on /engine throttle low - whatever . I fly PCM on everything gas .
