I purchased a 2.2 meter wood ARF drone from UncleGeorge here on RCGroups classifieds . I had been watchig it for awhile and when he lowered the price down to $99 I made the purchase . The first Issue I noticed was the over all light grey covering . Not good for overcast days or these 73 year old eyes ! I bumped up the outrunner size to a 60 size . Gets off the ground easily and climbs out with authority . The recommended CG is 70mm from the wings leading edge . It required two 5S 5000 mah LiPos to balance it at that measurement ! The batteries weigh 44 ounces ! I'm going to move the CG point back 1/8" at a time until it slows down and weighs less than it does . I also flew my Mistral ( 120" ) powered sailplane ( scratchbuilt ) . The Mistral and Drone both had their first flights this past Thursday , May 9 . The drone was very fast and the Mistral has a Dutch roll issue which I suspect is caused by two things . Not enough washout in the wingtips and way too much rudder throw , both easily fixed !
I have also been flying my double size Ambroid Jetstream powered sailplane . It was originally an A-1 towline glider from the 1960's . I actually took third place at a freeflight contest in Taft, California in 1977 with it . I upset the purests because I covered the flying sufaces with Monokote ! Anyway , I enlarged the plans to 100 inches and added an outrunner and radio control to the rudder and elevator . It has a lifting stab and undercambered airfoil on the wing which puts the cg at almost 60% of the wing's cord . Like all my planes I take the time to continuously make improvments until I get a great flying plane .

My first conversion is a Hitec Laser 5 SystemX . What a great radio. I would suggest that some of you glider guys take a look at this one . Lots of usefull features like putting throttle on a switch rather than throttle stick . It has a seperate menu just for gliders . Not bad for a radio that's over 25 years old . I have also secured many different radios and will post them here as I complete the conversion and restoration work . I also remove all of the compoents from the case, clean and reassemble . Many older radios were put away without removing the nicad packs which can destroy parts of the case and lots of the wiring . When a corroded part is removed I soak it in a mixture of 50-50 brown vinegar and salt . Leave the part in to soak depending how corroded it is sometimes overnight . When you remove it from the acid soak have a container of baking soda and water and immerse the part in the base liquid . Then after it appears that all of the acid has been neutralized run fresh water over for a minute or so, using a soft brush to knock off any tough spots . Dry the part either by air or use your heat gun . I use two old lidded plastic containers and keep the lid on between uses for the acid and base liquids .
Added pics of Cirrus and Aristo-Craft radios that have been restored and await their 2.4 components . By the way, the Aristo-Craft Hitec radio was before Hitec was it's own brand and is not poaitive shift like Futaba . It is negative shift like JR radios . So a...Continue Reading

Purchased a framed up Falcon 56 and was going to finish it, but decided it would be easier to scratch build one . I have plans and a N.I.B. kit so I zeroxed the kit's balsa pieces and am cutting out new parts . Building another kit, sort of . But putting in lots of updates like steerable nose gear, an O.S. .25FSR w/pipe, ailerons , nonremovable empennage , etc. Having to engineer the firewall area, which is pretty small, and getting everything to fit without interference is challanging . But that's what you do when you have fifty years of modelling experience . Sure beats buying an ARF, shaking the box and out comes something that might have been built safe and strong and light . Or was it ?
As the project progresses I'll post some pics .
