RE: [RCSE] spar-sizing calculations

Bill; This calculation gives you the minimum spar cap size and the maximum deflection at the maximum load. The stress in the spar caps (sigma) will be reduced in proportion to any increase in the cross section area of the spar caps. Therefore, if you double the size of the spar caps the stress

Re: [RCSE] spar-sizing calculations

You might want to consider increasing the wingrod size. I am. The 1/4 size was chosen for weight considerations, and at best it was a conservative (read:marginal) choice. I will use 5/16. On my BoT-to-be, I used a 5/16 wingrod and strengthened the spar with carbon fiber, end-grain balsa

RE: [RCSE] spar-sizing calculations

After looking at this more, and with this good advice, instead of 1/4 wide sparcaps, I'll use 3/8 wide sparcaps, tapered to 1/4, and maybe from .042 to .060 thick, as well as a stiffer 5/16 wingrod. A bit moer weight, but I'll look for other places to save weight. Take care, --Bill From:

Re: [RCSE] spar-sizing calculations

Great discussion, Don. Quick question: the wingrod in this Windfree needs to be bent to the dihedral angle of 16 degrees. The wingrod material I have is from DreamCatcher and is listed as high strength steel. It's polished, with a precise diameter, so it's not piano wire: Iknow nothing of

[RCSE] JR Programming help second request

Second request. Ah, come on guys. Someone out there knows how to help me program my JR388. I want full house flaps, ailerons, crow, mixing, etc. No problem so far. Plus I want to turn on an electric motor. There's the problem. How do I do it? I know there are JR pros out there. Help me

RE: [RCSE] JR Programming help second request

If you're doing crow on the throttle stick you have a problem. I would suggest moving crow onto another channel, either a switch or one of the pots. There is one more way. You could potentially use the mixing switch(should be on the left hand side right at the back (on top)), set up a custom
