OK, I've got a stupid question. I can't find any specs on the 24%. Can anyone let me know all the basics? Wingspan, fuse, weight, suggested engine. I didn't see anything on the planesplus site.

Thanks

74" wingspan, 9-11 lbs, OS 160/Saito 180 in that range of engines

Wow, that was quick!!!! Thanks!

I'm gonna try and work with Don soon to get all these specs on his site. It's lacking all the stuff people want and need to know before buying one.

Truth
wingspan 72"
weight 10-12 lbs
I dont remember the length but it is as long as my 30% extra 230 (long in otherwords)
Planes plus advertised weights cracked me up at toledo ( or does someone actually have a 9 lb 27%'r out there) with a motor that is

The 27%'r is listed as 11-13lbs.

I'll have to dig thru my pics but Im pretty sure they were lower than that at toledo but I would like to see someone build a 27% at 11 lbs and actually make it balance. anyway just as a heads up the aileron extension tubes in the wings did not line up with the fuselage tabs on my 24%. I had to drop them about 1/2"on the fuse to get them to line up

Well, I finished school for the semester, and now it seems like I'm busier! I got my Moki today with a Bisson Custom muffler. I can't wait to fire it up. I don't really think the picture below shows just how substantial this engine is. I'm going to get an 18x8 prop. People seem to feel this gives the most thrust while still maintaining crisp throttle response.

I bought a Heli, a Raptor 30, so my time has been into getting that ready for flight. My hover training is progressing slowly, but surely. That explains the lack of updates. I've also been working about 50 hours a week trying to save up some cash for future projects, and a nest egg to get me through the next school year!

Onto the project at hand...Wreck, can you comment on the relationship between F-18 and F-19. One is glued to the turtle deck, and the other is glued to the hatch, is that correct? I just need to cut the hatch to allow them both to fit in nicely, and they should also be laying against each other in a perfect installation, true?

Thanks!

Hello rplumbo,
Have you had time to fly your 24% Extra? I would like to have your feedback with the moki 1.8 in the nose because I am considering the option to put an MVVS 1.6 in mine (26CC).

I dont'know if I will sacrifice weight for more power, depend of your report!

Does someone know the wingarea for the 24% and the 27%??
Thanks for the help.

Hello Hawk21
Unfortunately, it's not written in the instruction manual and neither on the CA website. So, the only way could be to measure it ourself! My 24% is still in his box but I have 2 separated wings easily measurable.

Is there an aerodynamics formula to calculate the max 'flying weight' of plane based on the wing area to get optimum flight performance?
Scoubidou

Well scoubidou I do this:
Get the wing area let say 1150 and divide it by 144
1150/144=7.99
Then get the weight let say 15 lbs and multiply it by 16,
this will change the weight to oz
15x16=240 oz
And finally divede the weight result by the wing area result
240/7.99=30.04

30.04 will be the wing loading for that amount of wing area and weight.
Remember the lower wing loading the better

This way I know the max weight the aircraft should have to
fly light, to be in the good range or to be to heavy.
Hope this help
Benny

Hi Hawk21,
I did some research on RCU and 30 oz/pi2 would be to heavy for an aerobatic plane like the 24% Extra300. That size (120-140) should have 24-26oz/pi2 of ratio like a pattern plane.

I have measured my wing area and I calculated 855 in2 without the fuse area. If I can keep my plane at 10.5 lbs (168oz), I would have the following ratio: 168oz/5.937ft2=28.29 . That's the best ratio that I can get with an MVVS1.6 in the nose! Probably I will need to mix the ailerons with flaps to reduce the landing speed...

I asked to planesplus the recommended wing area and oz/ft2 ratio without success until now

You ever finish this bird?

24% planes are too small for gassers if you want performance. You'll knock a pound off your plane if you put an OS 1.60 in it and you will have more power.
