The best ARF I have ever flown would have to be my CMPro FW190 with a Zenoah G26. Plenty of power, gentle handling, very gentle stall and easy landings. I wish they made one for the Zenoah G62, I would be first in line with the bucks. Col

RE: Landing war birds.. HELP :( can't seem to get it right...
My experiences tend to back up the statement by Mustang51 about U/C leg rake angle. Prop up the tail of the model so that the aircraft is in a "flying" attitude sitting on its mains. Look directly down on the LE of the wing from above. If you cannot see 50% or more of the wheel, or see the axle if the wheels are removed, in front of the LE then this may be your problem. I have yet to assemble an ARF warbird that didn't need modification to meet this specification. Hope this helps. Col

RE: Twin with out thrust
Hello Ed, I have built and flown two Pilot Twin Ace models. The first was powered by OS 25 FP's and had 5 degrees out thrust on both. Engine outs were not too much of a problem. The second had 2 degrees out thrust and was powered by OS 30FS engines. This was a real handful on one engine and I eventually gave it away after yet another prang. I have come to the conclusion that 5+ degrees out thrust on both engines helps in engine out situations. I will also avoid overpowering twin engined models in the future. My $.02 worth. :) Col

RE: Giant Scale Planes Fulk Wolfe 70"?
[quote]ORIGINAL: Novato This is what I'm doing exactly right now, Zenoah recommends the 16 x 8 2 blade prop for the G-26, and Master Airscrew states that the conversion from a 2 blade to 3 blade prop is to substract 1" from lenght or 1 degree of pitch, but Master Airscrew don't carry a 16 x6 or a 15 x 8 3 blade prop, but Zinger does, so I'm planning on using the 16 x 6; what do you think S1? [/quote] I have the CMPro (GSP/Flair) FW 190 with a Zenoah G26 fitted. Zenoah recommend a prop range from 16x10 to 18x8 from memory so I have initially stayed with the lower end of the range, a Master Airscrew 16x10 two blader. This gives me 8,500 rpm when using premium unleaded fuel (BP Ultimate or Shell Optimax in Australia) or 8,100 using standard unleaded fuel. I also have a Master Airscrew 16x10 3 blader for ground trials when I get a chance. I was unimpressed with the paint scheme but left it as was initially. I have since added a red "Defence of the Reich" band to the rear fuse and some light grey and dark green blotches to fuse and wings. I have ordered another decal set and intend to do a splinter scheme at a later date. Having not read anything about tailplane problems previously I assembled this area as per instructions. I was horrified to note that at higher speeds the entire tailplane developed a low frequency flutter which luckily did not increase in frequency and cause damage. On investigation I found that the entire fin/tailplane area could be flexed. The fuselage sides below the tailplane LE would warp and allow excessive movement of the entire rear end. I drilled a 1/4 inch hole through the fuselage bottom and up through the tailplane where it is epoxied inside the fuselage. I then inserted a 1/4 dowel up through the fuse bottom and tailplane until it bottomed out against the fin leading edge. This seemed to strengthen the structure considerably so I epoxied the dowel in place. I have not experienced flutter since and there seems to be no damage to the tailplane. The undercarriage are another area of concern. The retract rails are too thin and not angled correctly to allow enough rake forward to ensure good ground handling. I modified them by removing the foam beneath the forward rail and filling with laminations of epoxy and wood from medical tongue depressers. The rear rail was built up by building up the mounting with 5 thicknesses of the same wood on top of the rail. The result was considerable forward rake but the dremmel needed to be applied to the rear of the retract mounting box to ensure clearance for the retracts. I fitted ESM retracts (chinese copies of Springair) and got lucky, mine don't leak, but they did require mods to increase resistance to side loads. Overall I am very happy with the model/engine combination. It would be a good basis for modification to a more detailed scale model. I am attaching some pics of the model before the first flight and landing after a recent flight. Col

RE: Fiberglass Fuse - What's Next? Ju 87D-5 Stuka?
Hello Leo, There seems to be a lack of suggestions for late war models of Japanese fighters. These generally had characteristics invaluable for modelling. Wide track, well raked forward undercarriage for good ground handling, radial engines with their large cowls to make installation of a variety engines easy, minimal taper to the wing suggesting gentle stall characteristics and great looks. I suggest the Nakajima KI-84 Hayate "Frank" as a project. It has all the good qualities mentioned above and should present few problems in manufacture. Col

A visit to the local hobby shop and the outlay of a couple of bucks should get you a packet of restrictors to put in the air lines. I almost drove my retracts through the top of my ARF Sea Fury the first time I actuated them. Scared the crap out of me. :) I only need one in the main air line to slow them down but you can also put another in the line to one of the retracts to give differential movement of the legs when cycling.

RE: Smaller vs Larger Size Warbirds
Hello Pat, I am also a recent graduate to larger warbirds and I know the feeling exactly. After cutting my teeth on 40 sized models my first larger warbird is an ARF ESM Sea Fury of 72" span, Zenoah G26 and 11.5lbs of weight. My main problem is in the landing of these warbirds on our club's grass strip. Every landing would end in a tip up onto the nose. Some good advice and a think about what is occuring has almost aleviated the problem. My landings suffered from not understanding what was happening in the final few seconds before touchdown. I would keep power on during final approach then, as the model crossed the threshold and neared the ground I would chop the throttle and flare. Now, as I chopped the throttle the flaps slowed the model dramatically and I would lose elevator authority due to the reduction in airflow across these control surfaces. I would pull in excessive amounts of back stick to compensate which had the effect of slowing the model more. This vicious circle would end with the model touching down with very little elevator control and, if I was lucky, would only result in a noseover. A fellow club member, tired of watching my botched landings, then gave me some advice. (thanks Trevor) He told me to advance my throttle trim lever to a very fast idle before commencing my approach. Viola, the very next landing was a greaser, as were the following few, and I was feeling very pleased with myself. That night, I thought it over and came up with the following possible explanation. The very high idle mean't that when I chopped the throttle with the stick the engine would maintain a reasonably high RPM and therefore, a certain amount of propwash over the elevators, these would remain responsive and thus allow a gentle flare without the usual overapplication of up elevator. The flaps allowed the model to slow at a known and predictable rate at the high idle settings and enough elevator authority remained to help counter the noseover tendency. I am no aerodynamics expert but this experience has resulted my own theory that warbirds need power on during the descent to provide airflow over the tail surfaces and that flaps provide drag to counterbalance the thrust generated by this power and allow the aircraft to slow for landing. As for using flaps during deadstick landings, the loss of an old Precedent Low Boy 5 taught me that this was a no-no. To sum up, don't worry, lots of us went through the same stage as you are in now. The use of flaps and retracts will come naturally with practice. Don't give up. I hope my ramblings have been of interest or encouragement. [:)] Col

RE: Skyraider Aviation FW190
Thanks for the replies. I managed to track down the maunfacturer at a recent warbirds meet here in Australia. The manufacturer is actually Skyraider Model Aircraft Productions in Yatala, Queensland. I arranged a visit to the premises and found that the FW190 is one of a range of glass fuse and foam wing kits on offer. From memory there is two sizes of FW190, a 90 size and the one shown above for a G26 type engine. There is also a 60 sized P51 and PT19 to round off the "small models". I saw a quarter scale BF109, large, 100"+, P40 and P51 and the nearly complete plug for the mold of a huge (150""?) JU87 Stuka. Discussions with the owner, Horst Skottki, revealed that he does not have a website at this time so I offered my services in this regard. :) I also placed my order for a FW190 in the 25cc size. In the meantime anybody wanting information can phone Horst on, in Aus (07) 38075411 or international 61 7 38075411. Col

RE: KMP p-51 Quality ?
Fellow club member here owns an ESM (KMP in the US) P51 which suffers from terminal noseover on takeoff, landing and taxi. When assembling the ESM P51, and also the ESM Sea Fury, (probably others as well) always rake the gear as far forward as possible, even if this means hacking away at the wing. The retract rails are also rather thin and benefit from the extra packing when changing the rake angle. Col

RE: Pilot Twin Ace kit
Hello Chris. It depended on flight attitude and severity of assymetric thrust. (engine quit or engine lagged) Engine cut just after takeoff with speed low and nose high the model would almost flick roll towards the dead engine. Engine sag in the same situation would result in severe yaw towards weak engine followed immediately by a roll to the same direction. Normal flight engine out or sag would result in a roll to the dead or weak engine. If the engine sagged then recovered quickly the model righted itself with just a bit of tail wag. On approach with engines at idle the model just slowly rolled to the dead engine. Easily controlled. Hope this helps Col

RE: Pilot Twin Ace kit
Looks Great Chris, congrats on the addition to the family. :) Love the retracts, they will make a world of difference to its appearance in the air. One of the photos looks as if you have built in-thrust into the port nacelle. Be careful in the event of the starboard engine surging or quitting. I built out-thrust into both nacelles on mine. The orientation might not be such a problem with your colour scheme. Mine has black on top and yellow underneath but the yellow turned very dark in flight. (reflecting ground maybe) I would reverse the colours if I did it all over again. If in doubt, a yellow stripe and fin flash will sort it out. Don't forget in fight photos now. :)
