Spring , good point , no white stuff around here, rarely.. like once every 10 years... lasts for a couple hours.. I still have my snow shovel , just in case of a drastic climate change...

Mind those trees !!!

"Age and treachery will always overcome youth and skill?" ... if you have any energy left to do so .... hahahahaha

Trainer One

Hi Guys and gpw,

Finished my Trainer One from gpw's plans and what a nice flyer.Wing is removable and no struts for me. Motor is J250 ( I think!) with 2s800mah lipo on 72Mhz and hxt 5gm servos with carbon fibre pushrods. AUW is 205gms with Depron.

Build thread here: http://malaysia-rc.com/index.php?topic=8720.0

Once again , thanks for the plans .I really enjoyed building this.

No Struts huh??? Would you mind terribly posting a pic of your wing attachment ... That's a nice feature for storage and transportation ...

Yeah GPW, one reason for removable wings is definitely for storage.I have quite a few of those 3D stuff which seems to take up all available space..haha.

Weather here permits all year rc flying and we are blessed in Malaysia without the current earthquakes , massive floods , huge landslides or typhoons currently around the Asia region.We do have rainy and windy days .

To hold the wing securely to the fuselage I fabricated a front and a rear saddle out of 4 pcs each from 6mm depron.The front seat is contoured to the fuselage shape and an extra piece on top of the rear to prevent the wing from 'sliding' off. All attached with screws and wooden plugs. Hopefully this helps for those wanting to store their "Trainer One".

If I did that with my FFF T1, I am sure that the wings would brake during a tight loop.
At one time I had just one pair of wing braces and the wing flexed during a loop pull out and it went straight into the asphalt from 50 ft up - SPLAT!
So , my question is:
KC, are you using some internal reinforcement in the wings?

Sounds exactly like what happened to my wings. I added a dowel along the LE and TE and better struts and haven't had a problem since.

Good discussion regarding loops.
I know I haven’t had any probs yet. I go into a slight dive first & wot on the up swoop and as soon as it hits inverted I go to 0% throttle, totally off & finish the loop with elevator only. No throttle until she starts to lvl off. I do have a good amount of hotglue in this plane and that is probably helping quite a bit as I don’t really see any flex in the wings throughout the loop.

I added two struts to the trailing edge and a bamboo skewer on the trailing edge that connects the two struts - behind the prop and connecting to a post that goes down through the fuse (just behind the prop). If you hold it up to a strong light you can see ALL of the skewers I have poked through the FFF. Maybe I should just build the plane out of skewers and cover it with that thin film, whatever it is called, eh? LOL - FORGET ABOUT FFF?

The struts do add a tremendous amount of strength to the wing .. I don't know if I'd be doing any looping without them ... Although a novel idea, can't say as I'd recommend the removable wing... Best to build it like the plans ... well tested...

It would be easy to retrofit removable struts as per plan but the plane is more to putter around in a scale fashion and definitely to show a beginner how easy and slow an rc trainer can be.So no looping here. Anyway with the motor used I doubt I can loop it purposely or snap a wing while cruising.

Wjbite , no reinforcements added except for toothpick pegs and epoxy at dihedral joints. Furthermore Depron tends to harden quite a bit with the use of a heat gun although I am not sure the same applys to FFF stuff which is not available here.

I've done a search but can't find anything for certain.... I've seen some thrust numbers and I see the thrust numbers on this motor but don't know how they compare:

http://www.hobbycity.com/hobbycity/s...idProduct=5358

It says 130g of thrust but it says /5000RPM.... I've got several sizes of 4, 5 & 6" props. Will this motor get my T1 airborne? I've already got one is why I'm asking.
