Eric Robson Posted June 3 Share Posted June 3 My 109e is ready to test fly, looking at the forecast it won't be this week so more details can be added the cockpit canopy is pinned on waiting for the pilot. Ready to fly weight I 5.375lb including battery. 14 Quote Link to comment Share on other sites More sharing options...
Chris Walby Posted June 3 Share Posted June 3 Hi Eric, Looking really good there. What lipo are you using in the 109? Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted June 3 Share Posted June 3 Hi Chris, The usual 4s 3600, I have used a different motor to the ones Richard supplies, just because I had one, it is an Overlander 4260 500kv which is probably a lot more than it needs. It balances without extra lead, Richard's motors will be fine as the mount will be further forward so equating the weight difference. 2 Quote Link to comment Share on other sites More sharing options...

Eric Robson Posted June 6 Share Posted June 6 Successful Maiden today, not the best conditions blustery wind but it handled it well, I belly landed it due to the gusts. As with the Tempest the elevator is very sensitive, so it only needs 5mm up and down. It may require more in calm conditions. 10 Quote Link to comment Share on other sites More sharing options...

There seems to be an awful lot of help, support and ideas with the builds, which would be of great use. What would the approx cost of a kit be with post within UK? Sorry for the delay chaps , Ive been away for a few days . Jon , the Fw190 is £139 and the Tempest is £149 . Both require £10 post in the UK . You are correct in your assessment . All of those who watch and contribute on my threads are extremely keen to convert others to this practical way of building and flying . You will always get loads of support . 3 Quote Link to comment Share on other sites More sharing options...

Silver Wolf Posted June 6 Share Posted June 6 No mistake in what it is, really shows the character of the 109. 👍 If it flys in anyway that it looks, then you’re going to have some very enjoyable flying sessions. 1 Quote Link to comment Share on other sites More sharing options...
John Timmis Posted June 9 Share Posted June 9 Here is a bit of make do & mend. Being brought up during the war this comes naturally to me. The photo shows what happens when you fly through an oak tree. OUCH! DON’T ASK! After a couple of weeks I examined the remains & thought it’s not too bad after all, It’s repairable. The tailplane & fin was an easy glue job, the ply motor mount had broken away on one side & the forward fuselage side was cracked. The ply cowl sides had broken free & this enabled access to reinforce the fuselage side. So far so good. Wing next. I had some 2” pink foam so it just came down to replacing the damaged areas, splicing in a new LE , sanding to profile & covering with brown paper. I messaged Richard & he confirmed that he could supply a new cowl & canopy plus a few other bits. THANK YOU RICHARD. Jobs as good as done. Almost ready to fly again. Richard thanks for the help, I’m an even bigger WR fan now. 9 Quote Link to comment Share on other sites More sharing options...
RICHARD WILLS Posted June 9 Author Share Posted June 9 No problem John . You made a brilliant come back on that model . She looks even better than before . Ive seen ARTF fliers chuck a good model with 10% of that damage . You have practically built it twice ! Quote Link to comment Share on other sites More sharing options...

Chris Walby Posted June 11 Share Posted June 11 Good rebuild job there and just a few signs (not that I can see them) of in service repairs/patches. A good reason for only one wing bolt! Quote Link to comment Share on other sites More sharing options...

Power train Preditor 580kv and 14x9x3 master airscrew prop and 4S 3300mah. Just ask Richard... Hi Paul, Have you got any figures of amps and/or watts for this setup? I've got an Overlander 4060 500kV and have just picked up a 14x9x3 prop and could do with a steer on what the likely numbers are running on 4S. The above is to be fitted in a warbirds spitfire which I'm (slowly) nearing completion of.

Paul Johnson 4 Posted June 15 Share Posted June 15 Hi Kim, You might find the 500kv a little lacklustre on rpm for a 4S. It will give more flight time but would probably need to be at full throttle for most of the flight and be close to stalling speed. I would look to something closer to 600kv.

Paul Johnson 4 Posted June 15 Share Posted June 15 Richard has been sourcing some 600kv motors at a good price that would do the job well 1 Quote Link to comment Share on other sites More sharing options...

That's exactly what I was worried about. I've seen a 4260 600kV which would probably be better then. I'll have a scout around and see if I can find one in stock somewhere- my lhs was supposed to get one in, but it was a no show on the delivery 😒 Thanks Kim Eta just seen your last post - maybe I'll get in touch with Richard 👍 Edited June 15 by Kim Taylor Quote Link to comment Share on other sites More sharing options...

Or of course anyone else who's able to comment, please feel free 😀 Kim Sorry to quote myself, but just for the purposes of experimentation, I did what I could have done in the first instance, and swapped the prop on an identical motor to the above, which I use on 6S in another plane. So, 500kV with a 14x9x3 prop pulls around 470watts on a half charged 4S. By calculation, a 600kV would show approx 800watts, or a little over. So as Paul says, 500kV would be decidedly limp, 600kV should be more than adequate. Just thought it might be useful Kim Quote Link to comment Share on other sites More sharing options...
RICHARD WILLS Posted June 15 Author Share Posted June 15 Useful stats Kim . The short coming of looking at just Watts is that you could for example put a large diameter ,low pitch prop on and measure a high wattage . Implying that the power would be enough to fly a model of a certain weight (based on Watts per pound ) . But here is the problem . The above mentioned prop will draw current (and therefore watts ) but not shift the air at sufficient speed to get the model to its comfortable cruise speed . If we look at your 500kv motor for example , hooking it up to 4s will give 500 x 16v = 8000 rpm with no prop . Knock off say 2000 rpm for the prop load and you are turning a prop at 6000 rpm . Nowhere near what a 6" pitch would require . A 6" pitch prop would need about 9-10K and an 8" pitch about 8000rpm . So when you put 600kv in the equation , you get 16 x 600= 9600 with no prop or perhaps 8500 with a prop in the air . That works with a 8" three blade rather well . 9" pitch would give a little "War emergency boost" . Two blade props will allow the motor to unload much better ,so you could use an 800kv motor on a 12 or 13 x6 and get longer runs on the same performance. Static testing is unreliable in my humble opinion as the air being shifted is "dead " . Once the model is moving its like riding your bike with a 50mph tailwind , hence you can back off the gas and still go as fast . So to summarise , two options for models of this size . 1) 580-650 kv with a three blade 13 or 14 dia x 8 or 9 pitch . (scale look , better climb 5mins from 3300 , more torque to manage on take off) 2)800kv with a two blade 12x6 or 13x6 ( sport look, worse climb 7mins from 3300, less take off swing ) Richard 2 2 Quote Link to comment Share on other sites More sharing options...

Chris Walby Posted June 17 Share Posted June 17 Murat, Going on holiday at such a crucial time and missing the super important news, shame on you! Before the Mossie's are dispatched all potential pilots need to undergo conversion training by flying both the WR Spitfire and WR ME 109 that will be available shortly. 😉 I am sure a quick message will secure your name is added to the order book 🤪 Then build and add them to your hanger stock, by the time you have done all of that the Mossie might be ready for dispatch (never rush a good thing!).
