Right then, this could indeed be interesting. I've been captivated by Rich Harris' autogyros at the Greenacres fly-ins over the last few years and, not least Tom Wright's Cranefly thread here on the forum and really fancy one myself. So here goes!

The model is from the plan Rich sells here. This is what it should look like when complete.

Cancel all leave Richard, I have a feeling some help may be required crook

In truth it's not the balsa bits that I suspect will be a challenge, rather the setting up, balancing etc...

This is the fuselage body after a week or so.

A few modest deviations - it's quite a 'brick outbuilding' of a fuselage so I'm using a thinner balsa for the top deck, I'll probably make a ply hatch cover, we'll see.

Servo wise, I just grabbed a few spares so those are Jamara 2kg minis in situ.

So far so good, and here's the main mast coming along. I'm not sure I'll bother to face each side with balsa.

The fuselage boom is stated as 6mm carbon tube - it was probably my...er....'building' but only 5mm seemed to fit when all was done so I've used 5mm tube inserted into 6mm. Same at the tail for the supports.

A bit of incentive for you.


Defintely go with colours you can see well. Biggest problem with autogyros is orientation. The Firefly flies like a trainer. As long as your hang angle is set right, and you choose a suitable day, your maiden should be one to remember.

Cheers,

Simon

David,

Looking good so far, it is pretty simple to build but the fun part is the flying. Slow flying, fast flying tight turns, power off glides, loops, stall turns and even rolls for the brave but the best characteristics are they are impossible to stall!

I can go on all evening about them but the only way to find out for sure if its your thing is to have a go, I take my hat off to you mate thumbs up

Ooerr..... too many moving parts all going in the wrong direction, but I could be persuaded if the maiden video shows a satisfactory result. indecision

Cheers lads...er... I have bashed balsa before you know smile psmile

....but not for a while and I'd forgotten how absorbing it is too. It's all rain forcast down here tomorrow so I should have some more building time.

The motor I've selected is another 'spares box special' - an Overlander 2836/08 which is good for 250 watts when spinning an 11x7 on 3S if I remember correctly from previous installations.

the washer adds the side thrust.

Good stuff David, I too started a Fire Fly 2 build a week ago and I am just about at the same level as you.

As you have said, I think the build is not going to be the difficult part here and have been scouring the net for hints and tips on setup. Fortunately there are several 'walk-throughs' for beginners which give simple step by step advice on how to get from small hops to actual flights. The original Rich Harris build blog in particular is an essential read for anyone building this model.

I have completed the head changes and making and balancing of the replacement triangular fibre-glass blade holder plate. The 10 minutes spent balancing this plate was worth the effort since what started up as a wobbly affair ended up in a smooth running assembly.

I will be following this thread with interest and if you like can throw up a few pics. of my build and also let you know how my (steep?!) learning curve goes on the flying front.

Peter

David, Peter,

 

Had an afternoon down at Old Warden yesterday and one of the 'locals' (who is a forum member) was flying his FF II in a light breeze to good effect. Of course I had my video camera to hand so asked him if he didn't mind me filming a flight for 'inspirational reasons'wink 2

He flies well I thought?

thanks Rich.

My best 'inspiration' moment was the video of you (?) gunning the motor and then putting the Tx on the ground while the FF took off on its own. Stability or what?

I think your better half accused you later of doing a dance as it soared away.

Looked like it to me.

Peter

Thanks Rich, that's good to see. I'll have lots of questions about the set and flying down the line but for now I'll take it one step at a time and get her to that stage.

Hi Peter, good to hear from you. I'll be looking at the triangle later this week I think. I'll probably cover the fuselage first, perhaps make the tail feathers too beforehand. Feel free to pop some piccies in this thread, it would be great to see them.

Latest pics here show the top deck hatch pinned into place ready for sanding to shape. The mast is done - I won't bother with facing it with balsa I don't think, it seems strong enough?

The motor mount is in place now and I've found a cowl from an retired E-flite Nieuport 17 that might finish off the front - we'll see.

Peter: yes I too think Rich was dancing, Now I tell you first hand that That Fire Fly -ll is now mine because of Rich's generosity and his dedication to advancing Autogyro flight not only over the big pond and all around the globe.

David if you build the fire fly to the plans you too could do a hands off take off.

The FireFly-ll is a very dosal and forgiving Autogyro and a great first time model. You will enjoy it.

Bill
