Mike, Jersey modeler makes one for glow also. It is on there site.

I have used SonicTronics pumps back in my glow fuel days. It works on 6 or 12 volts.

I also used an Ace Power Panel which has a pump. This was my go to set up when I flew glow.

Both of these are reversible - pump in and pump out.



If you need or want the Sonic Tronics pump, I'll send it to you Priority Mail for $10. I probably won't ever use it.

For gas I use a hand crank MPI pump.

OOOPS! sorry for the wing picture, but I can't seem to be able to delete it.

I'm similar to Jim Branaum, didn't have very good luck with the electric glow fuel pumps, they didn't last long, the rubber seals would break down during the off season while in storage... that's why I went with the Dave Brown Six Shooter... it's very simplistic in operation, its basically rollers around a large drum, the drum has a crank knob on it which you turn and the rollers run against a piece of silicone tubing, which squeegee the fuel through the tubing, works in both direction... the only thing that would need replacing is the silicone pump tube in side the case, but that lasted me a long time on glow fuel.... the gasoline version seems to be holding up just as well.



***EDIT***

R/C ART, I have the exact same power panel... I still use it on my glow twins, great little power panel

Well I guess I'm just lazy! Here they are, ready to go.

How about take the hand crank off off a crank pump and replace it with a spinner. Zap it with an electric starter.
Just a thought. I have not tried it.

Hey you're not lazy, if they hold up then you got a winner... the std rotary pumps used a rubber disc with flexible vanes; those vanes were short lived... the rubber diaphragm type had a similar problem.

If that Jersey Modeler pump were a true rotary sliding vane type, then it would worth every penny... it says the pump body is made out of delrin with a stainless steel shaft, and a teflon diaphragm; those are some good quality materials... lets us know after a season of flying if they're holding up... I'm tired of cranking too, those cheap handheld / cranked stepped up gear type are awkward to use and not worth looking into, and I'm done with those electric box pumps... a good quality electric pump would be worth the expense.

What like these... lets us know how they hold up after a season

John, I have no doubt they hold up due to club members that run them. I just never got around to finding where to get them until the aggravation of not being able to pump the smoke oil at that event.

John_M_

Well anything would be better than hand cranking... I was filling up my aircraft the other day, I was on my knees and had my back to the guys sitting over at the benches... there I was cranking away like mad, when all of a sudden one of the guys said "take in easy with that John, its not like you still in high school"... I turned to them and said I'm just filling up my plane you buggers

This what I have been using for over 12 months now with no problems.

John_M_

drac1, wasn't that intended as a jet engine fuel delivery pump... do you know what the delivery rate is?... the reason I ask, it was stated on one of the sites, it has a built in ESC to control the speed of the pump, that would indicate its was meant to be used on board the aircraft, but if its flow rate is not too hi, then it looks like it would make a nice fill pump... is it reversible?

Hi John,

Not sure about the jet application, haven't heard that. It was advertised for glow/gas use. A google search doesn't bring up any jet related uses. Also, as it's all aluminium with steel gears, it's reasonably heavy. Not sure what the flow rate is, but the slowest speed is all I use for fueling up.

Yes it's reversible and has a esc built in. There are 3 buttons on the back to control direction and speed, but reverse is one fixed speed. Forward speed is adjusted by pressing a button which increases speed in stages not gradual like a normal esc. I would think for a jet fuel supply pump it would need to be fully variable not only adjustment in stages.

Thanks drac1, you are correct, I managed to find the pdf manual, it is intended as a fuel transfer pump, fill & remove... its a bit spendy at $135, but I think that is ozzy dollars... anyway its an interesting design, gear type as you already mentioned, but the pump is completely encapsulated and sealed from the electrics... brush-less motor, nothing to wear out really, if the electrics hold up is should be a long lasting pump,

Initial cost is high, but I spent more on replacing cheaper pumps. A once off purchase that will last for years.

As with everything, I don't mind paying good money for something that will work as it should and continue to work. I'm not the least bit interested in using things that don't work as they should, don't last or require continuous fiddling to work.

These are the best I have used.

Tmac, we need a name and place of purchase or a pic that is enlargeable to see it.

Ok, will take a photo tomorrow. I purchased mine from DA Australia, they are made by SECRAFT.

I forgot to fill you guys in on a tid bit of info. During that event I did not have full throttle, or at least it did not sound or fly like it. Saturday morning I finally downloaded the tele and the max rpm was 2800. So I commenced to trying to figure out why. It did not take long (Short version) to find the plugs were toast, especially when one died shortly after running it up. So I changed the plugs and then it was running 4000 rpm with the big prop on it. The old plugs were RCEXCELL and were replaced with NGK. Something to think about next time your engine is not running just so.

Captain Lucky paid you a visit.

Finally got to ground run the three blade, woo hoo. It ran 3900 rpm om the ground which is great to me and the pull felt about the same as the two blade. The smoke inlet is better, there was no loss of rpm but the sound did change still. If nothing come's up I am going flying tomorrow and hopefully the wife will shoot some vid and take pics.

We can't wait to see! Good luck and happy flying!

John_M_

That's not too bad RPM Ace, considering that engine's max RPM is around 6K.. it will unload some it the air and the the rpm will increase a bit... the sound change is normal with the smoke on, the expanding denser smoke fills the exhaust tubes and changes the sound propagation through the exhaust system... the fact that there is no RPM change is a good sign you have the smoke injection point in a good location.



John M,

ahh look out

did you ever see this one ?

acerc

I have not seen that, could it possibly be the White Eagle? I have not seen a pic of the white one.

ahh look out

I came across it looking at pitts s1 pics and at first I thought it was yours. Then looking at pilot I knew it wasn't . Figured you would like to see it though. Keep up the good work
