My events are:

Perky, Fox 35 Speed, Sportsman Stunt Speed and 25 Fun Carrier.

No racing events from me this year.  But the usual Foxberg and Clown, by others, are still in.

Details often slip by the Brodak flyer.  If something is missing I can post again.

 :)  Hi y'all!  Well, I got bored and decided to build one of the Brodak profile Bearcats that I had sitting on the shelf  ;D.  The build was fairly smooth and I used all the items recommended in the instructions.  Now for the part that I don't understand (since I've never flown a carrier plane nor have I ever see one other than on You Tube).  Today, I hooked up an OS 25 r/c, in keeping with the rules for the Brodak "Fun Carrier" event.  The hookup went smoothly enough but it appears that as the plane would be flying and pulling outboard, away from me (centrifugal force), it would drive the throttle to the full closed position.  Thus, one would have to squeeze the trigger of the three line handle to open the throttle (by pulling the plane towards the center of the circle).  Is this the correct setup?  Should the throttle be setup so that the throttle would be fully closed (thus killing the engine) when there is no pressure on the trigger?  I look forward to learning how to avoid destroying this thing on it's first flight  %^@!   LL~ LL~

(p.s.:  If anyone is interested in providing it a "good home" please feel free to drop me a pm as it has not been flown and really should be under the control of someone who knows what they're doing  ;D)

Some like the throttle set up to have the trigger forward for high and pulled rearward to slow. Some prefer to have the trigger full back for high and move forward for slow. Your choice.

I'm one who likes forward for low, back for high, like a motorcycle throttle. I have heard that others set it up like an airplane throttle, forward for high, pull back for low. If it works for you, it's right. You said full "off" will kill the engine. If the carb has a low speed stop screw adjust it so that the engine is still running (barely) when the throttle is full off. If not, you will kill it in the air and/or be unable to go around in the case of a long landing.  8)

Your choice on throttle set up.  I have flown my Bearcat both ways with two different engines.  Right now with the Webra .32 it is forward trigger for high.  Discovered this after changing engines and not getting a test flight before hand.   Seemed to work better and I left it that way.   As stated there should be a throttle stop so you can control how low the throttle can go or you can control it with another control arm between the main bell crank and throttle arm.  Do a search on Bill Bischoff's set up on here.

I use high speed with the throttle pulled back. I like to think of it like an electric drill. You pull thigger to make it go and let it off to slow down.

I've done the throttle both ways.  For a while I believed it was a coin toss decision.

I have been MADE to believe that PULL for high is better because it tends to put full tension on the UP-DOWN lines at high speed when you  might need all the flight control force you can get.  With this setup in Carrier (and especially Scale) you can rig the throttle line so you CAN'T kill the engine with the trigger.  Then you CAN kill the engine by tweaking the throttle line with your other hand when you want to end the flight.

That being said, I have set up plane with PUSH for high (like real airplanes) but now I have seen the error of my sinful ways.

Gentlemen, to each and everyone, let me say Thank You!  I will toy around with the setup as you have suggested.

If you want it to go the other way, simply flip the throttle arm around so it points up instead of down. Re-bend the throttle pushrod as required, and you're good to go.

Sometimes that's easier said than done due to exhaust, muffler and fuel tank interference.

I have some planes with reversing bellcranks to get the direction and throw correct.

Looking at the picture of his plane, I don't think that would be a problem in this case.

Guys I've got my "Fun Carrier" plane all together. I did away with the arresting hook being operated by the movement of the elevator and installed a micro servo near the tail to operate the hook release. When the weather clears I'll start learning how to fly it. Hopefully I won't rekit it learning. Pics to follow.
