There is a reason that they quit making those. My 503 DCDI was a pain to dial in to keep my EGT in check. A full turn is all there is between "to hot" and "acceptable". The EGT temps still run about 1075 in level flight according to my EIS. WOT on climb out gets me about 6550 rpm. If you melt a piston, a new engine will cost you a lot more than a prop.

Really a nice feeling to have a supportive group. Something about pilots and sailers, (when I was Hobie sailing).. that really makes a person feel good. I told Larry about helping others build or repair their U/Ls way back when, and teaching 2 of them to fly. I did their test flights too.. to check things out.. and maybe to instill confidence in their aircraft. As for new props.. yes I agree 100%, new and improved would be much better. When I went to Georgia to pick up this Twinstar, the trailer provided was really heavy and with no brakes. Oh, great fun, pulling THAT down the road with all the sun worshipers out to view the eclipse, and basically driving like crazy people. Sorta glad they are ON THE GROUND, and not flying! I had to swap vehicles with a friend.. but in doing so had to pay her lapsed insurance, and then found 2 bad wheel bearings on the drive to my house before the big trip. Doing it myself was only(?) $300 (or the cost of a good used IVO!!). But I knew she was sweating bullets money wise.. so it was helping her, and me.. to have a hearty tow truck. One guy at a rest stop looked at the rig (with no brakes) and then PRAYED for me, cause I hadn't reached the Smokies yet! (Nothing like being puckered with that commentary). But the trip went fine. I just knew it made for an expensive "rental". So Karma may be smiling for helping her out too. My issue is adjusting the pitch of my billfold!! The prop should be more straight forward. And some classic R/C kits will go onto RCGroups to help fund this rework. I have some options now, and will be able to get it in the air.. and make some decisions. Main goal is to do some flying before winter, so I can bring it back home, and do some rework over the winter, knowing more specifically what issues to address more fully. Having looked at numerous other forums on here, some have ZERO activity. So it's really nice to see this group is active, supportive, and very willing to share knowledge and more. I LIKE it!! Pretty excited about doing some flying soon!! Thanks to all for the input and assistance!!

Those who are using top feed for your plastic fuel tanks: what pickup tube & tank fittings are you using?

I don't recall how I managed to secure my extension, but I am sure I had to go to solder to get it done. Here are some pictures of what I use. My theory was that a flexible tube with a weighted filter pickup that could slosh around to where the fuel was no matter the attitude would not be a bad thing. The little filter was from Model airplane fuel pickups. The fuel line being inside the tank has never been a problem and is still flexible and it has been there for some 20 years.

I agree Larry. Flexible fuel line pickups work great. Never had a problem wi th them on my MKII. I do think that the tubing should checked annually. And a fter a short time after initial installation just be sure the tubing used li kes fuel. My Firestar has a custom aluminum tank which is a bottom feeder. Works well t oo. Fuel system has a Facet electric pump and a pulse pump with fuel filters before and after pumps, thanks to information from those on the kolblist. George H.

From: "Jerry-TS-MkII" <12flybellaire@gmail.com> I would strongly recommend Tygon fuel line only. It's resistant to all the fuels, stays flexible, and doesn't expand. On a U/L I used generic clear tubing, with a "tight" press fit inside the cap fitting.. but one day while fueling, it FELL OFF! Use spring clamps on all connections, or large diameter safety wire with a few wraps, then twisted snug.

From: Charlie England Thanks to all for your responses. Very helpful in clarifying my path forward. What I have in mind is very similar to what Larry showed in the pics. Plan is to use the same blue urethane tubing that's used for the rest of the fuel system. Larry, is your in-tank tubing 1/4" ID, like the feed to the pump(s) and engine? Do you have a link to the fuel filter? All the model filters I've been able to find are for 1/8" ID tubing. I've got some plastic inline filters for 1/4" line that I can adapt, but I'd have to add some weight to hold the filter down.
