RE: F3A? Not anymore! (conversion photos)
The best prop will be found by flying it, and will depend on several factors. Line length and model weight are keys in this. I like to use FAI length lines (15.9m) for 15 size models, and have found best performance under about 500grams. Good luck, it's a good looking set up.

RE: PAW .40 R/C needle adjustment
One of the hard things to learn about tuning diesels is the interconnectedness of the compression screw and the needle valve. Took me a long time to learn that as you open the needle you automatically increase the compression. More fuel = an increase in compression. So by opening the needle by 2 turns (seems a lot to me) you are really cramming fuel into the cylinder and therefore upping the compression.

RE: Phantom Mite
Hi Chris, That's nice work. Is that a PAW 1cc up front? It would be of help to you to fly with other control line fliers in your area. Where in UK are you? If you haven't already found the Barton Forum, let me recommend it to you. http://www.controlline.org.uk/phpBB2/index.php Personally I wouldn't use and fabric lines, instead I'd look for some .008" Brodaks do them, you may also find something suitable in fishing tackle shops. Good luck with the Mite. regards Greg

RE: Replacing lost Ether in fuel?
[quote]ORIGINAL: Bill Adair John, Thanks for the Ether storage, and fuel freshening tips. Wish we could buy Ether retail here in the US, but our only source appears to be diesel starting fluid spray cans. There are commercial sources of diesel fuel in quarts and gallons, but we can't get it locally. I've always favored tin cans for field use, because I can drill the caps for any brass tube arrangement that I like. Bill [/quote] Bill, It sounds as if you need to make friends with your local illegal drug manufacturer! They don't seem to have any trouble getting as much Ether as they need. (Joke) But you might need to find someone who has a company where chemical suppliers are prepared to deliver solvent ether. Or make friends with the local F2C Team race fliers - they are bound to have a regular supply. Regards Greg

RE: Replacing lost Ether in fuel?
Bill, Put a small amount of your fuel into a graduated cylinder and leave it open to the atmo to gas off. Mark your starting level. Over a short period (a day or so - depending on the weather) the ether will evaporate, and the oil and kero will separate. The oil will be on top of the Kero. Instant (well sort of) determination of your fuel mix. Then simply add enough ether to bring it back to original spec. Probably easier though to simply mix a new batch. Regards Greg

RE: Line Tension
All I would add to Da rock's encouragement to whip, is to learn to identify when your engine is about to quit, and really put your effort into whipping then. It'll give you more control to set the model down pretty much wherever you want or need to. Good luck mate.

RE: fuel mixes
Hi Jonny, The ingredients are ; Ether to ignite the kerosene under compression ; Kerosene to burn under compression and provide power ; Oil to keep it all slippery, so you have to wipe the model afterwards [:)] ; DII to smooth the run and allow more compression (more power!) The ratios are as variable as you are prepared to experiment, but it must work for you. And you may use as much or as little of any component as long as you are happy with the outcome. If you want to run 5% oil, it's your call but if it's a plain bearing motor be prepared to replace it regularly. Shelf life depends on how well sealed your fuel container is. Ether has a very nasty habit of evaporating from all but the best containers. I keep my ether in a 2litre Winchester. Wrapped in plastic and kept in a dark fuel locker.

Your assumption that it is that model has another connection.

I've heard it said that this is the best flying Spit of all. Please show pics of your restoration. If you're going to RC it are you going to add dihedral to the wing?

RE: Flexible Diesel Fuel Line?
Hi John, Tygon works well for all my control line needs, including the fuel crusher type shut offs. The small size (about 3/32" is best). It can be stretched over a flame to thin it even further and probably make it more flexible. Hope this works for you.

RE: fuel mixes
Tony is right 7% is the current oil content, and each compitietor will have ideas on what additives and %ages to run. One of our Club members was the pilot for the recent World Champs win. Part of the "secret" of their success was he ability to assess any changed engine tune and to then have variable fuel component delivery at the pit stop, to ensure the engine stayed at peak during the entire race. Sorry a bit off topic. In short there is no magic bullet that says the fuel should be this or that mix. As long as you have Ether, oil & Kero you're in business. The amounts are up to the individual. - Go play and ahve fun.

RE: fuel mixes
Modern TR motors (TBR & AAC) can use as little as 10% oil. For TBR motors I like the Ollie brew 20 oil 30 ether and 50 kero, any ign improver is added to this in the range of 1.4 -1.8% depending on temperature (air temp). This basic mix, my pit man & I have been using in VTR for many years. Given these numbers engine cooling is critical, therefore the cowl needs to be spot on. For PB engines, at least 25% oil, but can still run 30% ether. Add a touch of Ign imp to taste.

RE: HOW DO I CONVERT?
Marwen, you don't say whether or not you have previously flown CL. Assuming that you haven't, and that the Delta is set up for R/C, what you need to do is: Take out the R/C equipment (all servos) Lock the ailerons to level, and rudder to about 5deg right. Install a bellcrank, roughly on the centreline and for convenience at the CG and connect to the elevator. Add a leadout guide to the left wingtip. You probably need to have this go a fair way forward of the wing itself so that the leadouts are far enough forward to ensure sufficient line tension. Add wingtip weight to the right wing to counterbalance the weight of the lines.. A couple of technical considerations: Your leadouts need to be at such an angle that if you suspend the plane, the nose naturally points out by about 5deg. CG for initial flight needs to be set a good way forward, about 10-20% of airfoil Control movements of the elevator should be restricted to 15 -20 degrees for first flights. For best results try to fly with established CL fliers in your area. There's no point making mistakes that others before you have made, if you can help it. good luck with this and let us know how you go. Regards Greg
