Texaco Running Steady

Are you going to use it on a plane?

Hi Ken
Yes. Although I have cars and boats. The planes are the best for me. I really want a motor that can run 5 minutes. Seems I got there. Although these Texacos won't win any speed races that's for sure. If steady slower a bit it's ok. My Medallions squeek three minutes. My TeeDees 2:30-2:45. Granted screaming pretty much but a slow and steady 5 minutes is sounding pretty good.

Thanks

Just wanted to finish up this conversation for me. After Fred super super kindly sent me some 8x4 props all the way over here to Korea. My two Texacos are running very well. One runs 5:05 and the other runs 5:25 minutes on single tank. The 8x4 prop seems to hold the RPM low enough that the venturi can supply steady enough mixture. Runs quite good. Slight pulsing but just a couple hundred rpm and then returns to high speed but pretty minimal. Really nice prop wash! The hose over the NV seems to be better with a washer pushing it down.

Thanks a million Fred you have really helped!! Kind Regards

I think you are a bit obsessed with smooth running-very few of our engines will hold constant rpm for any extended length of time-and a variation of +/-50rpm is nothing-even a few hundred rpm is not unusual-and as for in the air-well the prop load will vary depending on whether  the model is climbing diving or in level flight. You've got your 5 min running target-now go and enjoy it...perhaps you might also reflect that you achieved it by running the engine on the prop size and rpm regime it was designed for... which is usually a good idea....I find it is usually a good idea to assume the manufacturers know what they are talking about when it come to their own products...!
  Can I suggest that money spent on a tachometer is rarely wasted-it solves a lot of guesswork and arguments-and gives you a solid foundation to reference fuel props and plugs against.....and they are ridiculously cheap these days compared to 30 or 40 years ago.

Thanks Kiwi
Appreciate the comments. I do get out and fly. However I also am very very picky and insist my motors to run as best as possible. So I wanted to thank Fred for helping!! Where I am there are no parts and is next to impossible to get motors complete. Also Mudhen was also awesome on helping earlier too.

NZ is nice spent a few weeks there in years gone by. Fishing East coast. Drone fishing also. For our limits.

I'm not a fisherman myself-but I know several fellow kiwi modellers who are.....common themes.....something to do with standards, equipment and patience I guess...the point I was making that you may be attempting the impossible if you're hoping to get a Texaco to run in an unvarying rpm fashion over the entire tank-and even if you could achieve this on the bench-(unlikely BTW)-it would not occur in the air...

Hi Kiwi
We got our limits everyday. Also crays were abundant. Pulled 1000 meters line off shore with electric drone and loaded up. Snapper and all sorts. Matarangi area. Yes thanks for convents on the Texaco. I appreciate the professional connects and kind help from done of the members I mentioned. Mudhen and Fred. Both awesome.
