Another Backplate Question....

Another Backplate Question....

Post  NEW222 on Wed Dec 05, 2018 10:01 pm

Looked, but didn't find anything on this, so here it goes. I just purchased a couple of engines and they are sitting here boxed up due to my own stupidity. I bought a couple engines from a gentleman and as a joke, I said I was going to get the box in the mail and wrap it up to myself from Santa, just to see the look on my familys faces when I open it having them all wonder where it came from.... Anyways, back to the question. There appears to be a Black Widow with a Babe Bee type metal backplate with 2 filler tubes. However, the Black Widow tank also has the stunt vents. So, with this knowledge, is there any problems with running the engine as it arrives with vents on both the tank and backplate? Does anyone know if I will I encounter any problems with it running in this configuration? So, until I open this package, I will be looking into this. Thank you.

It will run just fine with a normal vented backplate, you just don't want to do any crazy stunts with it or you could lose fuel.

Yep. Gravity may ruin your day, and your fuel economy.

One could probably bridge the fuel up nipples on the tank back with a short piece of fuel line. Caveat is may fall off in flight from vibration. Another is plug the tank back nipple holes with a piece of toothpick. This will allow pushing out with a piece of music wire later to restore the nipples. And there is always the solution of replacing the tank back with the non-nipple version, which is a fairly inexpensive fix.

Great, thank you all for the help. I like the idea of the toothpick in the backplate vents as it is easy to remove later, but I had not thought of a small piece of fuel tubing bridging the two backplate nipples. While talking about that, I do have some small heatshrink tubing that I may also try now. Just a small piece on each nipple. Now just to wait till I can open the package....

Actually I was thinking of a small loop of fuel line (or other tubing) looping from one nipple to the other. However, there are solutions out there, left up to one's ingenuity. Jacob is right, in reality you really don't need to do anything, unless you like to do things like fly inverted, axial rolls, outside loops, etc. Otherwise, the fuel should remain in the tank until burnt.

Regarding flying RC inverted, I did that with my Golden Bee on my Q-Tee, but it only stayed inverted for a couple seconds. These tanks don't have a clunk pick up, engine quit and I dead sticked in. Smile

The engine will be bench run, and put into a control line model, and inverted is not in my routine, unless be accident.... A wingover or two, and possibly a loop if I feel like trying to do anything other than straight and level. Thanks again for the help.
