Why 35cc or 45cc airframes ???????

       Remove this ad - become a site supporter!
Why are companies putting out 35 to 45 cc airframes ? They average in the 75 to 79 inch wing span area. A nice sized plane. But......Motors in that size range seem to be not very abundant.
Let me rephrase. There are engines in that size range, but the cost is no less or usually more than a descent 50cc. Not to mention they don't really weigh any less than a descent 50cc if at all.

Then a lot of people are shoe horning a 50cc into those smaller airframes, for the very reasons mentioned above.
The power is tremendous. Something everyone likes, myself included. But, why not just put together a 50cc sized airframe. The cost savings of the smaller airframe is negligable. Most 50cc airframes have unlimited verticle and fly extremely well.

Some will say the size of the smaller airframe is better for those with smaller vehicles.
I have a Toyota Yaris, and for giggles myself and another fellow from around here put a hangar 9 Carden Yak in it. We could close the rear hatch and both sit in the front seats.

I can not even remember why i started this thread LOL...I guess I am just bored

Re: Why 35cc or 54cc airframes ???????

satisfying market demand = profits

It's no different than making .40 size glow planes when .60 size would be much better.

Re: Why 35cc or 45cc airframes ???????

That price is insane!!! I just got done reading through all of the reviews and there had to be a 100 or so. All were good reviews except one person had the prop adapter break after 50 flights. Sounds like you should throw away the manual, but for 175 USD that is a steal. You can buy 3 for the price of one evolution!!!!!!

Maybe it has to do on how model airplanes were classified or categorized back in
the dinosaur times when model airplanes were about building and a few gratifying
time to see them fly. They were Class A (.09 to .15) Class B (.15 to .29)
Class C (.29 to .60) and that was it for the gas and glow engines of that period.

Since and most recently with IMAC, 3D, Giant Scale, time has changed our
RC World. With the advent (new era in RC) ARFs are well JIG built and fly
like a dream, we are now have a fraternity of FLYERS and no longer BUILDERS.

Why 35cc to 45cc well, it is like boosting a car for racing. The new popular
generation of model airplanes are now as an example, take a YAK or what have
you. You can buy it at whatever scale from the actual a/c 30 or 40% . If
you dont like the performance with 35CC, you go to thre next size up.

That is the only explanation that I can come up with. I am 74 years old
(old fart) built with stick and tissue and banana oil, flew Wakefields rubber contest, etc
but I DO PREFER MY FUNTANA 90 and love my Hirobo Shuttle. Born to early.

Keep up the spirit.

banana oil used to attach paper to planes. Hmm, I'm a young fart and this was well b4 my flying days.

I've now read about it and discovered it smells like Juicy Fruit gum.

Sure beats smelling CA

Good stuff.

Re: Why 35cc or 45cc airframes ???????

Banana oil? Sheesh, I didn't even know you had to oil bananas!

I wonder how many people would still be in the hobby if we woke up one day and there were no arfs or kits like we have today? Or imagine, no Futaba 14 M radios and all we had were the old galloping ghost systems!

OMG, you mean I have to design and build my own plane from scratch? Cover it with tissue or fabric & dope. And flying it, I push the button, what is it, 1 click for right turn and 2 clicks for left turn and a whole bunch of clicks to get it to centre!!!! Yep, those were the days eh what?

We really have it good today. My goodness, when I first flew back in 1975 I bought an MRC 3 channel radio and it cost me like $250, only came with an RX & 2 huge servos. Had to use Everready cells for the Rx & Tx. If you saw a plane that had a 60" wing span, you thought, Geez, how much bigger are these things going to get.

I'll take the selection we have today anytime over that but it sure was interesting times especially going back from there another 20 or 30 years.

It was also the day when you could mention dope and nobody looked at you funny. Never could get the banana's to work for me. Every time I spread them out and rolled it on a wing they never did turn to oil. Awful smell after anyways before it hardened.Ha
