I bought 4 old RC foamie planes at a garage sale and know little or nothing about them and would be pleased for any info or tips you have, for example the size of lipos they use, the, CG, etc. update: since making the video I Googled the reg no on the big foamie biplane, N7020L, and it's a model of a 1999 Waco YMF -5c owned by Island Boat Lines. F5c and uses 3300mA 4s. Though still don't know CG. The big foamie Harvard I know nothing about apart from the fact it has a 3 inch speaker and amplifier in it. That was a first for me! The glider was easily identified as the Dynam Sonic 185. Has great reviews. Been around since 2010 I think. CG 60mm and that is sorted. The Messerschmitt Bf-109F is Alfa Model CZ. It has a 30A esc. Pretty much sorted but no idea what recommended CG is. And yes, I know, I could go with a 1/3 of the chord, but recommended might be better! So anything you can tell me will be useful, thanks.
I got some great old planes at a garage sale, can you help me identify them please?

The bipe cg will be a bit behind the lower wing leading edge since it is total chord. 1/3 is typical for Clark Y flatbottom and variants, good starting point, but dont work on my NASA semi symmetrical series which could be at 50%. Somewhere there are online drawings or assembly instructions that show optimized location. There ought to be a qualified response along in a short while.
Thanks for that. And yes, I usually work on a 1/3. I have built a couple of bips and worked on 1/3 but of a midpoint between the two wings, (which was advice I'd seen a couple of years ago online, which seemed ok. ) But the good news in I found a manual download for the Waco recommended is 70 - 75mm on upper wing.
So far no info on the Art Tec AT6 Texan (Harvard) so will have to guess CG and lipo.
