    Sport Midwest Cap232 (old kit) DLE55

    I built one of those Cap and put a Brison 3.2 on it. Not a weight problem a tall. In fact, I had he battery right behind the FW to balance it. It flew pretty well whatever the CG was on the plans.

    IMAC Carden Pro 124 Build, My Dream Plane

    T-88 epoxy has a looong working and cure time and is very strong once cured. I used it on the parts mentioned above. The EZPoxy resin system is what I used to laminate the wings etc. It can be rolled on very thin and still works great! The big deal with epoxy and me is that I like alcohol...

    IMAC Dalton 300 ml build thread.

    I have had planes that had a vibration sound in them and after much hair pulling and gnashing of teeth several of us determined that the sound was coming from the fuse covering. The covering was acting like a drum at certain speeds which apparently has certain frequencies hence the sound! That...

    IMAC at small field

    Looks like your field is just SW of Lafayette but exactly where is the field located? I can look on Google maps and find it once you give me some directions. BTW, how was the class today?

    IMAC at small field

    The club that is across the river near Port Arthur (?) had an IMAC contest several years ago. It is a nice field and plenty of space for any size of plane. Contact Tommy Golson in the Baton Rouge area for more information. I would definitely make the contest if you were to put one on as I am...

    Philosophical questions on breaking a motor in... (Not an oil thread!!)

    You just discovered the major difference between old-school glow engine workings and the new-school gas engine workings!! The bottom line is that you tune a gas engine to almost optimum performance at the beginning (i.e. not too rich, not too lean)!!

    3D Gorilla Glue

    I used the same glue for hinges that I used to glue wood sheeting onto the foam cores of my last three planes and it has worked and held up well. That glue is EZ-Poxy! It has at least a two hour pot life and can be thinned with methyl alcohol, I did the ailerons and rudder side first. I used...

    The how do you setup your IMAC radio thread

    My setup is almost like Robo's - 10 deg elev, 25 deg aileron and 25 degrees rudder. This is for the Sportsman sequence flying only. Expo is only 15% as I am of the old school and any more than that feels "like I ain't got it"!! I do have three conditions other than sequence: Hammer where...

    IMAC Dalton 300 ml build thread.

    Last year's Sportsman would be a good "unknown" to practice and it's on the IMAC home page! I have copies of some past year's unknowns if you want to try a few just let me know and I can send them to you.

    Redrawing district boundaries

    The SW region is not the only one where great distances between contests are involved. The SC region use to have contests in El Paso and Midland/Odessa which were 3hrs apart from each other but another 3-6 hours away from most of the other SC contests. It took me 7.5 hrs to get to Ft. Worth...

    That's good. I thought you may have done that already but I thought that I would mention it.

    IMAC Dalton 300 ml build thread.

    Cam, have you gone thru this trim scenario - step by step? We found that Phillip's Sukhoi needed about 3/32" downthrust to get a perfect verticle upline. We used the last step in the chart after he got the CG and right thrust where he wanted them. The downthrust step is not totally clear as...

    Futaba 18MZ/14SG/8FG Tips and Tricks

    Yes it is a snap condition! Since it is a condition the rates for each surface can be changed without affecting the other conditions. The snap condition only happens when the throttle and sticks are in the positions I described!! As I said it is specific for the avalanche in the 2015...
