Its been a while since my Panther has been out but I managed a couple of hours up at the field yesterday morning, a bit warm but it was nice to blow the dust off her.

I was looking at the 3mm nylon ball joints wondering what their life span would be, I would hate for them to fail after 5 years. Maybe a change to some nice aluminium units, has anyone got any links to something suitable?

Also noticed that this thread has over a 1/4 million views now, quite something that!

A few snaps of the now tired looking prototype.

A clubmate was trying to get his Panther off the ground last week but it was rolling left as it lifted off. Not a success but repairable. I've printed out your guidance from about page 4 or so, I hope it helps him as it's a very pretty model and I want to see it fly! I wish I'd kept the plan now.frown

Denis,

Thanks for the info, I will have a look at what's available. I have tried the Hobbyking ones but lost faith in them as I had a couple pop out under the extreme loads of this application.

Bob,

Hope you clubmate has success, its been said many times before but the role to the left is classic signs of low rotor RPM. If he wants any help there is sure to be a gyronut around your area, let me know how he gets on?

The plan is still available HERE

I have found the Cruiser plan, something to think about in idle moments.

Bob, I may have a spare plan somewhere. I have just moved and am going up to Lancashire tomorrow for a few days. If you can wait till I get back I will have a look through the mayhem the move has caused!!!

There's no rush Bob, I have plenty to keep me occupied for now.

And thanks!

As promised last year,I have had an update from John in the US who has modified his Panther by adding a wing. Last week it had its maiden voyage and he was kind enough to send me the video of it.

To those that are interested the set up is as per the original, throws, hang angle, thrust lines etc. The wing is positioned so the CG lies roughly 1/3 of the wing cord.

At the moment it has only had a few flights under its rotors/wings but stability seems to be improved and orientation is far better at distance. As John gets more comfortable with his new flying machine I am sure he will relay back his findings, he is really pleased with it so far.

Video and a number of photos John has sent me.

Rich

I am building a Panther and have a couple of questions

(1) with electric is the motor ~built in~ the cowling.ie cowling not removable?

(2) My metal geared servos (new) have a little play in them is that OK.I am told all metal geared servos have some degree of play.

Any help would be welcome

Richard,

To answer your questions.

The cowl is removable, on the mating face of the cowl there are two lugs with holes in to which the fixing screws go through. These are accessed through the cooling hole in the cowl, if you like I can remove mine and take a photo which should explain things clearer? I have also managed to pull a cowl onto a mould using a 3 litre cider bottle to good effect. I do know to one Panther builder who shoe horned an Acro Wot cowl, there has been a couple with radial type cowls too.

As for the metal gear servos, the play should be fine, mine had them from new and the model has now been flying for 5 years, I also have a larger pusher that has seen 10 years service though this has titanium gears. More importantly is their available torque, if they are up to what is specified you will be fine.

Please keep us posted of your progress.

Point of interest, Sarik are now showing the short kit (plan, laser cut parts + additional wood pack less rotor blade material angry) for £81, a significant reduction from the £129 shown when I ordered mine 3 weeks ago teethangryface 8

I have emailed them about the lack of rotor blade material and untimely price drop, not to mention their packaging.

Richard F: whilst The detachable cowl approach is perfectly ok with electric power, it isn’t compulsory. I took a different approach with mine:

Trevor,

And all these years I have been making removable cowls, lateral thinking at its finest, never seen that before thumbs up

Bob,

I've never seen the wood parts pack so am unsure what is or what isn't included, that said I wouldn't be happy after shedding that much out. It would be like have a fixed wing kit with no ribs!

or, as I put it to Sarik, they have supplied me with a kit for a very fast, prop driven car.

Many thanks for all the help so far.


Going electric with this one using Emax motor BL2828/07 with a 60A ESC. Servos are Tower pro MG996R.

Still struggling to fly these machines properly but with some good success with Rich Harris Burky 2 design.The main issue is the rotors have ~ folded back~ on a turn .Do I need to tighten them more? was around a 15mph wind.

Have to say I am getting pretty good at making rotor blades.Will post some pics when time allows.

Richard,

Never heard of blades folding back in flight, they must be too slack.Tighten them so that there is a slight bit of resistance when moved, if they are too tight then the model and UC will shake.

I prefer the Cruiser in windier weather as its cleaner aerodynamically, you can use all the running gear from Burky (including the blades), food for thought wink 2
