Davy Posted June 4, 2010 Share Posted June 4, 2010 I''m hoping this will be the model to use for my B test, when i can find someone to take me for my A test! Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted June 4, 2010 Share Posted June 4, 2010 A very good stable model,enjoy flying mine a lot and looks good in the airEdited By Stephen Grigg on 04/06/2010 15:27:08 Quote Link to comment Share on other sites More sharing options...
Bill Brownlie Posted June 7, 2010 Share Posted June 7, 2010 Got one of these for Christmas. Flew it 3 times now, crashed it twice. It drops a wing like nothing else I've flown. Had to bring it in very fast then remembered the old article about turning the ailerons up a notch. As I had them on separate channels this ment setting some negative flap in to the normal position to raise th ailerons up about 1.5mm. This has the effect similar to wash out and was very effective. After my initial distrust and growing dislike I'm now warming to it again although I don't find it the easiest aerobatic plane to fly. It is very fast and has a tendancy to need a lot of rudder control (short fuselage), nice to look at though. Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted June 7, 2010 Share Posted June 7, 2010 Funny thing is Bill ,I was warned that the model would do exactly as you describe but Ive found the opposite.Ive spent plenty of time with the model now and can fly it surprisinly slowly and it still handles well.Ive always landed it to fast but now drop the engine a lon way away and bring the model down on a downward path flaring at the end.I do find I always bounce a couple of times but they are now low enough to be acceptable Quote Link to comment Share on other sites More sharing options...
Bill Brownlie Posted June 7, 2010 Share Posted June 7, 2010 mmm??? I've just read a couple of other threads which say the same as you. I've just finished a blackhorse renegade that I bought recently while waiting for the glue to dry on the HR repairs. After building it up I checked the CofG and was laying strip after strip of Lead on the nose to get back to the recommended position. I was at the bottom end of the engine size(46) and expected to add some weight to the nose but not this much. So I went back to a calculator I have and did the sums which came out at 25mm further back than the recommended position in the manual. This took the majority of the weight off and I've only had to add about 75gms. Been thinking about the HR I have an OS55 up front and have added some weight to the tail to counter-balance. I think I'll re-calculate the CofG tonight. Could be I'm flying her tail heavy Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted June 7, 2010 Share Posted June 7, 2010 Hi Bill,Ive an O S 46 FX in mine,dont think I added any weight and dont tell Gary but I prefer flying the HR to the Pulse and the Pulse is lovely to fly.Strangely my first Pulse flew faultleesly on an OS 46 LA,but my 2nd I fitted an OS 46FX and its not as easy to fly,so maybe engines can alter a models balance.I tend to fly nose heavy.

Tim Hooper Posted June 7, 2010 Share Posted June 7, 2010 Bill, I don't have a Rocket, but I've seen several fly over the years (one fitted with a 2lb+ 16-cell battery pack!), and all have earned nothing but praise from their owners for their stability and ease of control. I'd be tempted to check your CG.... tim Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted June 7, 2010 Share Posted June 7, 2010 Hi Bill, I always get a club expert to maiden flight any new model irrespective of what it is to check things out with me,on the ground and in the air.My particular guy is my instructor,superb flyer and takes NO prisoners.When I arrived at the field his words on seeing the Harmon rocket were "Youll never fly that there totally unflyable" As soon as it was in the air his attitude changed completely,and its the first time he has actually back pedalled and said he was wrong,I hope you find something so you can enjoy yours as much as I enjoy mine,good luck Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted June 7, 2010 Share Posted June 7, 2010 Bill,I just found my thread on my build of the Rocket and it tells me I added 100 grams to the front to get the c of g correct I you can figure out the weight of my OS 46 FX and your engines weights thats a starter,although I did have a couple of Seagull 40s and the weight difference was astonishing Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 10, 2010 Share Posted August 10, 2010 Hi Bill,How are you getting on with the Harmon Rocket and Renegade Quote Link to comment Share on other sites More sharing options...
Lee Smalley Posted August 10, 2010 Share Posted August 10, 2010 no tip stall tendency of any sort mine has asp 70 four stroke c of g came out nearly bang on with rx batt at back of canopy flies amazing Quote Link to comment Share on other sites More sharing options...
batcho99 Posted August 11, 2010 Share Posted August 11, 2010 Mine never stalls at low speed. Excellent handling model. Its fitted with a Saito72 four stroke as I have mentioned in the othe HR thread. think the common trend here is more weight up front, defo check your c of g. Iain.

Stephen Grigg Posted August 11, 2010 Share Posted August 11, 2010 Well I would think you both have much heavier engines in yor models than I do but as you say they handle superbly even at comparitive low speed.I seem to knock the power off a long way out otherwise the landing speed is a bit high.May be I should piut a spare SC 52 I have in it,or just enjoy it as it is Quote Link to comment Share on other sites More sharing options...
Bill Brownlie Posted August 11, 2010 Share Posted August 11, 2010 I've been flying the HR quite a lot recently as I'm still having problems with the renegade, another story. I'm realy comfortable with the HR now. Took some weight off the tail and kept the negative aileron setting. Still bring it in quicker than the floaters (Wot4, etc) but had no problems with it, it flys fast and sounds great with the OS. I'm practicing for my Silver Certificate (Scottish equivelent of the "B" but much harder) and I find the HR not so good at precision Loops. Need to fly it too fast to get a decent Loop without it wandering. At least I need to fly it fast!!!! Quote Link to comment Share on other sites More sharing options...
Lee Smalley Posted August 11, 2010 Share Posted August 11, 2010 no sorry bill mine rock steady and consecutive loops are a joy no real rudder input required at all, unless its blowing like the clappers Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 11, 2010 Share Posted August 11, 2010 Whats the problem with the Renagade,I did tend to take the u/c off a bit but apart from that loved it.I was flying it in dull conditions,everyone called lunch in my haste to land started to turn to far away to slow and tip stalled it,quite a skill really as I could never get it to tip stall normally Quote Link to comment Share on other sites More sharing options...
Bill Brownlie Posted August 11, 2010 Share Posted August 11, 2010 Its always blowing like the clapper where I fly. Its on a moor at the edge of a range of hills and the wind is always up even when its a summer breeze every where else. I damage the U/C plate and the very thin(1mm) ply bulk head just behind it where the front of the wing slots in on a dead stick landing just after take off on the second flight. I've rebuilt it 3 times now. First two times I tried to keep it as light as the original set up,just stuck some fillets behind the plate, but the U/C just came off on landing. I've fixed it again and it won't come off this time. I reduced the U/C width and fitted a 3mm overlay onto the former. If I crash it again the U/C and the bulk head will be the last men standing. Still to touch up the covering and its ready to go. No problems with flying it it handles realy well and floats in. If anything its getting it down is the problem especially with the wind recently, almost lands vertically like the Wot 4s up here. Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 11, 2010 Share Posted August 11, 2010 I remember the same problem you coulnt reinforce the wing mount so you were stuck ,there is so little to glue to isnt there. Quote Link to comment Share on other sites More sharing options...
NigelH Posted August 27, 2010 Share Posted August 27, 2010 Anyone seen this model electrified ? The engine / motor swap would be easy but I wonder how the LiPo would be positioned / accessed. I saw this model hanging up in the (not so) LHS today and I was reminded of what a good looker it is. I've sold all my starting gear so glow is now out of the question. And besides, with an SC46, by the time it was airborne, it was time to bring it in. Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted August 27, 2010 Share Posted August 27, 2010 Hi Nigel ,I fly mine with ans OS 46 FX and the flights last for ages ,cant remember ever running out of fuel.When I first flew it the throttle stuck open and it was up there for ages and the deadstick landing when it ran out was excellant Quote Link to comment Share on other sites More sharing options...
Bill Brownlie Posted September 5, 2010 Share Posted September 5, 2010 Not done much for a couple of weeks, been away working. But just before I did I had a few flights with the HR and spoke to one of the club gurus about the loops. I was trying to fly them too slow. A bit more speed on the way up and it was rock steady, throttle off at the top and she floats round into big circles. Really beginning to enjoy flying her.

Stephen Grigg Posted September 5, 2010 Share Posted September 5, 2010 Hi Bill glad you have balance your Harmon Rocket better now.With my O S 46 FX I find the engine runs out of puff when doingupward rolls or loops,never a problem because the model bahves itself so well.Ive cosidered changing the engine for something a little more powerfull,but because I enjoy the handling of it as it is dont want to upset anything.I found I was landing quite fast at first but once on straight approach have lowered the power and the model seems to stay stable from a long way off.A couple of Tuesdays ago it was very windy and I only had 1 flight and had an expert land ,he touched it down at almost walking pace,I was impressed.

Lee Smalley Posted September 6, 2010 Share Posted September 6, 2010 just a quick tip don't throttle off until just on the down section of the loop the airflow helps keep the loop round and the rudder authority good just as the aircraft starts to descend lower throttle to half or a quarter depending how powerful you motor is!! its a lovely model and will easily take you through your B Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted September 7, 2010 Share Posted September 7, 2010 Ive just had 4 flights with the Harmon Rocket and the engine was a bit lacking.We tried to richen it up but it didnt respond.Im going to fit a GMS 2000 .47.It was in a Seagull 40 and had loads of grunt.Im going to weigh both engines so I keep the same weight up front Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted September 7, 2010 Share Posted September 7, 2010 leaning it out is more likely to increase revs /power Quote Link to comment Share on other sites More sharing options...
