toto Posted July 18 Share Posted July 18 (edited) Email received from Motion RC telling me these were back in stock ...... FlightLine B-24 Liberator Olive Drab 2000mm (78") Wingspan - PNP [FLW401P] Motion RC Europe had to have it ..... its a beast ...... 2000mm wingspan and about 1400mm long. power cable and ribbon connectors from wing to fuselage and 4 screws ( 2 per wing ) to assemble at the field. 2 x 4s batteries .... already in stock. I bet they will run on bigger though to get more than the quoted 5 - 7 minutes flight time. I had been tempted by the B17 but held out for this. It was advertised as out of stock for the last couple of months and I thought that it would be a lot longer before it came back in. can't wait to get the chance to get this in the air. toto Edited July 18 by toto Quote Link to comment Share on other sites More sharing options...

Chris Walby Posted July 18 Share Posted July 18 I have the P38 and OV10, both fly very well as long as you don't take liberties with them 🙂 + I hear the Tigercat from the same stable is another great flyer. 7 minutes of flight time is plenty long enough unless you cane it around in an un-scale like way, anyway you have plenty of batteries. 1 Quote Link to comment Share on other sites More sharing options...

toto Posted July 18 Author Share Posted July 18 Erm ...... no ...... but I'll bet you could. I don't think there is anything that will bite on this ...... its big .... but in my opinion .... to a point ..... the bigger the better. These four electric motors won't give the same issues as four IC. Now there is a statement from a potentially niave newbie. Correct me if I'm wrong. Pussycat .... no harder than the Supercub .... just heavier. Toto Quote Link to comment Share on other sites More sharing options...

toto Posted July 18 Author Share Posted July 18 Thanks Chris. I'd like longer than the stated 5 - 7 minutes ..... not to fly as such but just a little extra in the tanks so as you don't take the batteries to close to the bone with the 7 minute guidance.

Chris Walby Posted July 18 Share Posted July 18 IMO I was given some very good advice pre and post A test, and that was to fly as many different models as possible, but especially ones with higher wing loading as its a new and important skill to learn about the mass of the model. As far as I am concerned models sub divide into two groups and that is those that fly like their full size kin e.g. Its a model of a B24 so it flies its full size or those that have been sterilised and fly like a big trainer and have no vices. The problem with the latter is they aren't so rewarding to fly and secondly you will learn less in the long run. Plus one day you might fly a model that is far less forgiving and they can really bite. Still learning to fly my 108inch ic cub, why, because it flies best with just the rudder and elevator...just like the real thing (so I have been told). PS I have had more one out on electric that IC twins, but its the same technique for both. IMO its best to avoid the possibility through PPPPPP. 2 Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted July 18 Share Posted July 18 Agree with Chris that the possibility of a motor out on electric twins is still there. In fact our first flight with an electric twin many, many years ago put my son off flying twins for good and that was simply at he loss of a push-on Gunther prop during the climb out. 1 Quote Link to comment Share on other sites More sharing options...

I'd like longer than the stated 5 - 7 minutes ..... not to fly as such but just a little extra in the tanks so as you don't take the batteries to close to the bone with the 7 minute guidance. Toto Throttle management, if you cane it around on full throttle (not scale) it will hammer the batteries, but if its gentle take off and mooch about with some nice scale low bombing runs down the runway it will probably do 7 minutes and land with 30% left. I flew the OV10 for 7 minutes and used 30% battery capacity, but with the 3 bladed props if I go over 75% throttle it does not go much faster, but will discharge the batteries far greater. Fly at full power all of the time and it probably won't make 5 minutes and you will be dead sticking it in. The problem is people want a warbird to scream around the sky and do un-scale like things, but IMHO that's not the point. I don't care if my cub can prop hang or do 3D, I just wait for a nice day and mooch about...if I want scary then I have the Focke Stick for that.

Toto ...One other word of warning when departing from a carefully designed and tested model...you might adversely effect its performance. Just a wild guess but say you want another 3 minutes out of the B24, ok stick batteries that are 50% bigger and now you have a very forward C of G. This is because the designers didn't expect such a large battery in the battery bay, but that's ok as you can just add weight in the tail. The problem is with the combined weight of the bigger batteries and lead in the tail you will increase the wing loading. The model will need to fly faster (more drag so the batteries don't last as long!) and will probably have a more abrupt stall so you have to land faster causing more UC damage. Just my advice, but stick with the designers recommendation for the first few flights Overly heavy and high wing loading is not a good combination and does not matter if its electric or IC.....how do I know... 3 Quote Link to comment Share on other sites More sharing options...

Simon Chaddock Posted July 19 Share Posted July 19 Toto With such a large and heavy plane I would not worry too much about the flight time. I think you will find 5 minutes will be plenty long enough to start with. If you haven't crashed within the first 2 minutes of a flight you probably won't but the longer the flight the chances of making an error rise. The critical part is always the circuit & landing. Compared to a flight duration it doesn't take that long but it is critical and needs to be mastered. Shorter flights will mean you keep within battery limitations and you get more landing practise. 1 Quote Link to comment Share on other sites More sharing options...

Heavy? Its 78 inch wingspan and sub 3KG (without batteries so still under 4kg with lipos) compared with the 63 inch P38 that's knocking on 3.5kg with battery. I am pretty sure the B24 will have a proportionally bigger wing area as well. The Ta154 (80 inch) was over 6.5kg and probably less wing area compared with the B24, now that's heavy. I think it will be a really nice flyer, but lots of experience with high wing loaded models before letting the B24 wheels leave the ground. Totally agree with the flight duration, its a high workload for the novice, gear, flaps etc oh and that other odd thing not on the A test.....rudder!

toto Posted July 20 Author Share Posted July 20 I'd be interested in how to fit a camera into this. It would need to be pretty small to fit into one of those front gun turrets and servo mounted but I'll bet its been done. More utube searching I think. If anyone knows of anything suitable....... chime in. Toto Quote Link to comment Share on other sites More sharing options...
toto Posted July 23 Author Share Posted July 23 The liberator is on its way. Mr FedEx advised that it arrives tomorrow. If I get the chance I'll post up a few pictures for those that are interested. It will just be a couple as these models are so well packed that they are difficult to restore in the box if you take everything out. I'd rather not do that until I am ready to do the permanent assembly. Looking forward to seeing the finish of the model for myself ..... all looks good on video. Busy trying to determine the best mini camera I could use for placement in one of the turrets. Great stuff. Toto Quote Link to comment Share on other sites More sharing options...
Chris Walby Posted July 23 Share Posted July 23 Entirely if up to you, but personally I would fly it out of the box for a good many flights before butchery. Adding weight to anything that flies in my experience does not improve the flight characteristics (some worse than others). Be interesting to work out the wing loading and then you would have a more informed idea of how much you could add...then see what's available camera wise + you might choose to loose some battery weight to compensate for the camera! Needs an update but you get the idea My SpeedAir which was my main model after the RIOT as it had more mass and a higher wing loading taught me lots, but once you get into warbirds its a hole new game! PS Measure wing root and wingtip length, length of wing and I'll do the rest. 3 Quote Link to comment Share on other sites More sharing options...

GrumpyGnome Posted July 23 Share Posted July 23 Cool. Peep in the box, put the lid back on. Fly the other models until you built up some experience. Only then take it out, assemble it, and set it up on your transmitter :-) 1 Quote Link to comment Share on other sites More sharing options...
