Hello all-
Please pardon the very newbie question. I am coming over from Nitro engines into my first gas engine, a DA-50-R.
Before I try and set this up on my radio properly, I really wanted to get the throttle basically working so closed was closed or mostly closed and open was open so I don't flood the engine trying to start it for the first time (etc., all).
On a nitro, I obviously can see the air intake opening and of course get a really good starting point for open vs closed by looking at that. But, on this DA-50, how do I tell? Which way should the throttle move? Towards the front of the engine for open?
Thanks for your patience and support of new modelers coming into gas engines.
You really answered your own question. Just look in the carb and like your glo engines, you will see the throttle butterfly operate when you move the arm. Easy enough to tell which way is open. On some gassers including the DA, sometimes there is an idle stop screw ... if that is present, when the throttle arm is against that stop, you know it is at idle. But, most gassers have these screws removed so you can't count on these. My DA pulls the throttle arm to the rear of the airplane for full throttle but I would not guarantee that all DAs are the same.
