5 of those biguns would have helped balance the Rascal! That would be nearly 5 pounds of lead I could have removed.
At some point Ni-Cads will no longer be available, in fact the EU and UK banned their sales for everything except Medical and a few select categories.

Hey Jim, there's a fella on rcg called Heggen, he drew up basic plans for both the 40 and 60 size DL last year. He sends plans out for cost of shipping.The original DL ARC manual is available online in pdf format

Yes, the availability issue is a future concern.
In the meantime, I am very happy with the cells I have been getting. And the reliability, predictability has been excellent since first using NiCds in the 1960s.
I am also very pleased with how well NiMh work in transmitters but I no longer use Delta peak chargers for them.

I guess I could buy the 1200 pack for my Worlds Model 46 size P-40, cause that's just a crasher plane

Guys i have a fuel question.I'm giving the fa115 a yearly birthday with new o rings etc and rinsing the fuel tank.Since i only strain the in going fuel to the tank with the normal inline filter after the hand pump, i thought it would be interesting to pour the fuel tank residue through a fine mesh coffee filter and see what happened.It had a lot of short white fine hairs trapped in it...i've seen this before, any ideas?
ps jim,a lawyer karks it and arrives at the pearly gates.Not fair, he said, I'm only 45, Saint pete said no, we got a new system.Now we do it by billable hours.According to our records you're 153.

I bought some 1800 or 1900 mAh NiCd packs on eBay last year. They were made for standby emergency lights so all I had to do was solder on the needed wire and Futaba connectors.
The price was right too.

this is something I will have to test for..
as for that lawyer, from the lawyer stories I have heard most likely he didn't stepped threw the gate LOL

Satan has a special room for all lawyers and politicians (and car salesmen) in Hell. When they enter the room everyone is standing in 2 feet of excrement, talking, laughing, smoking, drinking, and they think, well, this isn't too bad. They enter and a few minutes later a voice booms, OK, Break time is over, everyone back on their heads!

Saito 100 problem
Having an transition problem with my Saito 100. It is mounted upside down in a TF warbird; has a OB glow driver, and a pump. When transitioning from idle, the engine is sagging around mid range and then some times just stalls. If I slowly take the throttle up it seems to be fine. At high RPM is running around 8900 RPM. Also the high speed needle is very sensitive to adjustments. Checked the valves and they are good. The low speed needle is in along ways which is interesting. If I run slightly rich on the low speed it floods easy at idle and will stall. Any ideas?

If it's a new problem I'd try a new glow plug first. If that doesn't fix it I'd bypass the pump, disable the glow driver and retune. You shouldn't need either to run your fa100 in a TF warbird unless they botched the fuel tank location.

Tune the needles better. I had the same engine in a P-51 and could not get it to run. I reset both LSN and HSN, and got it to run so well it wouldn't shut off. Also check the tank position, it may be too high which is causing it to get too much fuel. Easy way to check, drain the tank, and fill it less than half and see how it runs. Do this first and see.

That is good news! The 40 size could be a treat and there are plenty of areas where weight could be trimmed from the ARF. I got this one as a "damaged, return" years ago. It had a few bruises and punctures. I will have to see if Heggen is still offering.

The tank position is why I went with a pump. It is a perry pump and is a new set-up/new plane; engine was tuned and broke in on a test stand right side up. The on-board glow shuts off around 1/4 throttle.

Sounds like too much pump pressure or your glow driver quit working. Is this a new problem with an existing set up or a new set up? What prop? What pump?

ps jim the small fine white fibre is not plastic,i use dubro or sullivan tanks and good fuel line.

A properly tuned engine running in an upright position on a test bench will require retuning when mounted inverted on an airframe. In all likelihood it will run rich when flipped over, especially if the carb has no velocity stack. Retuning is required.
Perry pumps are needed if your fuel tank centerline is very low in comparison to your carb spraybar or when your fuel tank is located farther back away from the firewall. I'm not sure with your TF warbird if either of those apply. I would try tuning without the pump though, one less thing to be concerned with for now.
Glow drivers can be useful especially with newly broke in engines where idle can be unpredictable. They can also camouflage an overly rich low speed needle (lsn) setting which I believe is what you are experiencing. Turn in (lean) the lsn until your transition gets crisp. You'll know you've leaned it too far when the engine pops or dies when goosing the throttle after idling for 15 seconds.

CDRC the above is very good advice,we've all done a flying tune (very different from running it on the bench) on a saito inverted in an arf with a high fuel tank position and there are many things you can do,so you end up with a smooth and powerful saito in your arf?? if you answer some of the above questions in a bit more detail it's easier to help you,pics are good too.

It's good you ran it on the bench first, that can alleviate many problems. Hopefully you've replaced the glow plug after break in? Even though a glow plug can look perfect after new engine break in runs there will be with tiny metal particles attached to the wire element. Replace it before doing final preflight tuning.
