Bob Bertram Posted July 16, 2018 Share Posted July 16, 2018 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!!! Bob Quote Link to comment Share on other sites More sharing options...

Richard Harris Posted July 23, 2018 Author Share Posted July 23, 2018 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.

Richard Franks Posted October 15, 2018 Share Posted October 15, 2018 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 Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted October 15, 2018 Author Share Posted October 15, 2018 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.

Bob Cotsford Posted October 15, 2018 Share Posted October 15, 2018 Point of interest, Sarik are now showing the short kit (plan, laser cut parts + additional wood pack less rotor blade material ) for £81, a significant reduction from the £129 shown when I ordered mine 3 weeks ago I have emailed them about the lack of rotor blade material and untimely price drop, not to mention their packaging.

Trevor Posted October 15, 2018 Share Posted October 15, 2018 Richard F: whilst The detachable cowl approach is perfectly ok with electric power, it isn’t compulsory. I took a different approach with mine: **LINK** Trevor Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted October 15, 2018 Author Share Posted October 15, 2018 Trevor, And all these years I have been making removable cowls, lateral thinking at its finest, never seen that before 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! Rich Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted October 15, 2018 Share Posted October 15, 2018 or, as I put it to Sarik, they have supplied me with a kit for a very fast, prop driven car. Quote Link to comment Share on other sites More sharing options...

DAVE MATTHEWS 2 Posted October 16, 2018 Share Posted October 16, 2018 plug :- I have a completed, flown, balanced ready to go Panther in the classified section of this site. £100 without Rx. East mids area. Quote Link to comment Share on other sites More sharing options...
Richard Franks Posted October 16, 2018 Share Posted October 16, 2018 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. Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted October 16, 2018 Author Share Posted October 16, 2018 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 Rich Quote Link to comment Share on other sites More sharing options...
Richard Franks Posted October 17, 2018 Share Posted October 17, 2018 Thanks Richard is the plan still available. I have the Burky 2 and el bandito but not the cruiser. Can I buy it anywhere? Will have to check my piles of Rome to see if I have the free plan.still unsure about the play in the tower pro servos what did you use in the Panther?

David P Williams Posted December 8, 2018 Share Posted December 8, 2018 Hi all - I bought a parts set from Sarik with their 10% off offer and am just starting to build the Panther. It will have an SC52FS and I just wanted to ask those who have gone this route whether they moved the firewall back or just fitted the engine to the firewall in it's plan position and had a longer nose> Thanks, David Quote Link to comment Share on other sites More sharing options...
Steve Jones 2 Posted December 8, 2018 Share Posted December 8, 2018 Hi David I have 2 Panthers, the second fitted with an inverted SC52 fs. My engine is mounted to the bulkhead but the bulkhead was moved forward 15mm and the nose shaped to blend. Engine fits in cowl perfect and silencer shaped in side cheek. Cooling is not an issue and keeps the lines Check out my Album on my profile for build pics and the engine installation - it’s the red model as the orange is the first with a 32 2stroke Steve Quote Link to comment Share on other sites More sharing options...

David P Williams Posted December 8, 2018 Share Posted December 8, 2018 Thanks Sreve, I've looked through your album - I had seen some of these earlier in this massive thread. I'm surprised you moved the bulkhead forward, I was expecting to have to move it back to keep the prop in roughly the same place but I guess that doesn't matter much. What was the reason for moving it forward rather than just leaving it as per plan? Quote Link to comment Share on other sites More sharing options...
Steve Jones 2 Posted December 8, 2018 Share Posted December 8, 2018 Moving forward allows more space for the fuel tank .. I use 4oz Slec which is ok but I would prefer a 6 oz for more flight time to be safe. The 52 is plenty of power but 5 mins on the 4 oz is short Extending the nose is not an issue for flying and I just balanced the model at the original cog position Steve Quote Link to comment Share on other sites More sharing options...
David P Williams Posted December 8, 2018 Share Posted December 8, 2018 OK thanks. I have both 4 and 6oz available so I'll try to fit the 6 in. Quote Link to comment Share on other sites More sharing options...
Richard Franks Posted December 26, 2018 Share Posted December 26, 2018 just had to post the fact that had a maiden with my Panther Christmas eve. ONE WORD WOW. flew straight off no trim really great. skinned the blades in lightweight glass cloth which only added about 45gm for the set of three but incredible strong. Proved a point on landing in the only tree in our flying field (orientation issues) and only bent the prop adaptor otherwise minimal damage. Starting to build another straight away. Hats off to Rich Harris. Quote Link to comment Share on other sites More sharing options...
Malcolm - coolwind.co.uk Posted December 26, 2018 Share Posted December 26, 2018 Well Done Richard Franks!! Its not orientation problems, its the trees they move every night ! Malcolm Quote Link to comment Share on other sites More sharing options...
Richard Franks Posted February 20, 2019 Share Posted February 20, 2019 Just had to post now getting good flights with Burky and Panther.Panther is far more stable than Burky.. Now realised the importance of head speed on take off and using rudder for the turns correcting the roll with opposite roll (Aileron).There seems far more more tendency to roll right. Left turns can almost be completed using aileron/elevator like fixed wing but must watch out for too much roll .Building the Panther now and intend to get two in the air at the same time (2 pilots) at our flying site. Any advice on achieving a decent canopy with the pop bottle method as so far not much luck? out aging this Friday Regards Quote Link to comment Share on other sites More sharing options...
