    Chris,' You should contact Barrett Precision Engines in Tulsa, Oklahoma. I guarantee you they will have the answers you need. 918-835-1089. Outstanding US overhaul shop. They have developed and have running a beautiful coil-over electronic ignition (one coil per spark plug) and fuel injection setup for the M14. Most likely you will speak to Rhonda first. Ask Rhonda if you can discuss some technical stuff with either Monte Barrett or Allen Barrett. They will also have cylinders for exchange. Rhonda's email address is Rhonda@BPAENGINES.com. Dennis A.

I did a lot of cross-country flying in mine. Every cross-country flight was a test flight. (Only aerobatic and formation flights were not used for data collection although I did find that fuel usage tended to go up when flying on someone's wing.) I would use various altitudes and RPM settings. I always flew with the throttle wide open, accepting whatever MAP I got. (Because the engines use mechanical superchargers, reduced RPM reduces maximum available MAP.) In flight, calculate TAS. Then land, fill up, and use your E6B to calculate fuel burn. (Calibrate your ASI first. I can provide you with a spreadsheet that will let you determine TAS and winds aloft from three GPS ground track and GS readings. You work backward to CAS from that.) I did find that, by giving up about 10kts of TAS, I could often eliminate at least one fuel stop. That ends up saving a lot more time in a day than going 10 kts faster would make up for. BUT, if you have a good fuel-flow gauge, you can get your data almost immediately and then collect several data points per flight rather than just one. The problem with using the fuel specifics, i.e. g/hp*hr, is that they change with the operating point of the engine. Also hp output is not completely linear with changes in MAP and RPM. It is possible to model the hp output from MAP and RPM for a given mixture but it is just a lot easier to measure it and plot it against the actual performance of the airplane. So, you set the power to something you think reasonable, e.g. 2100 RPM, full-throttle, 9,500', mixture leaned for smooth running, and then see what you get. When you land you can find out what your actual fuel burn was. After all, knowing the hp output might be interesting but what most pilots really want to know is what the airplane will do at a given power setting. Oh, be sure to be consistent in the loading of the airplane even moving the CJ can affect the performance results. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 brian@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA)

    Subject: Snap rolls Yak 50
    Hello I have recently purchased Barry Hancock's Yak 50 and am having some difficulty with the snaps. They run out of roll rate about 270 degrees and have to be aileroned. Going right and using max 200 kph. Anyone out there willing to share the secret ? I've watched the u-tube videos of the YAK 52 snaps but I can't see enough of the inputs. Also any lomcevak entries would be much appreciated. Much different than the airplanes I grew up in. Once I was told it takes 2 hands to roll I was quite relived. I thought it was because I just turned 70. Love the airplane! Many thanks, Gord Price

    How about a nice gentle aileron roll? Or a little faster, full rudder and ai leron seems to be the nature of the beast. Doing hammerheads I still need ai leron to make it look right.

    Gord, Good snaps in a 52 by: 1. Between 180-200 kph, induce accelerated stall 2. Almost simutaneously, aggressive full rudder in direction you wanna' roll 3. Again almost simultaneously, full "pro roll" aileron Once you get the timing of this down, a 52 will snap quite enthusiastic ally. Roger PS Recovery? Simultaneously (assuming positive snap), stick briefly forward o f neutral, center aileron and some opposite rudder. You don't have to "bury " the controls in recovery. As the snap is stopping, return all three to ne utral. This avoids a cross-over anything. PPS Everything with two hands on the stick PPPS All maneuvers done at least two mistakes high.

    Thanks Roger, I am close. I normally lead with some rudder, maybe that is the problem and yes timing is the key I think. Maybe I am not quite aggressive enough on the back stick too. Keep forgetting the 2 hands. Yes high is good, particularly as I work through the outside snaps where 3 hands would be even better on the recovery.

    I find loading the wings first with stick pull then full (right) rudder with all the rest that Roger said. Inputs are aggressive but not jerking. In roll aileron accelerates rotation. As will almost everything in the 52 as soon as you stop or check the input the maneuver stops - therefore, do not anticipate going neutral - force yourself to wait until wings are level (or whatever you are looking for) before changing control input.

    '52 ones work for me by: Use TWO hands.....

    OK .... That makes sense.... to unload the elevator to conserve energy and yes a conscious effort to keep it neutral with full rudder and aileron. That seems like what I am seeing on the snap roll on t/o video http://www.yakuk.com/video/flickme.wmv Thank you Gord

    Subject: Re: Snap rolls Yak 50
    I would echo the other comments here. My experience is in 52 and coached by Sergei. Snaps I use 120-140 mph (190-220kph) then firm neutral back stick. Immediate right rudder. When rotation starts stick to the right toe. (release back preassure and pro-spin aileron really speeds the rotation.) Then recovery. For the lomcevak. Be very comfortable with inverted spins and recovery. Start at least 4000 AGL for practice. Lower dive for airspeed acceptable. Enter 60 degree pitch up at 220 mph (350kph) then roll inverted. Full left rudder followed with immediate full forward right stick and hold inputs. Hang on. As energy disipates the plane will wind up forced into an inverted spin if the control inputs are held. SO as the energy disipates, close throttle, recover with opposite rudder and stick back / neutral as the nose comes down and the airspeed builds. Remeber the above is for 52. I never did lomcevaks in the 55 I owned. I am super conservative and only do what I know how to do. I feel comfortable with the above after doing countless with Sergei in the back seat. I did not have this opportunity obviously with the 55, so I was more cautious.

    Right toe... I like that and it makes sense. I was limiting the speed to 200 kph to keep g load to 5. Do you recall what rolling g you get at 220? Thank you for the Lomcevak entry. I will give it a go tomorrow. Gord

    Guys, just so you know who you are dealing with....google Gordon Price Canadian Aerobatics, or World Aerobatic Championships. He may be 70 but still out flies most guys half his age.... Good to see your having fun with #001, Gord! Happy Flying, Barry -------- Barry Hancock Worldwide Warbirds, Inc.

    Barry, Thanks for the bio note on Gord. I was happy to pass along to him my bit about what worked for me in snapping a 52....Just as I was happy, using my 52, to check you out in inverted spins a few years back....passing along what worked for me. I think that's the way it's supposed to work. Glad the "first 50" has gone to someone who will use it, enjoy it, and fly the pants off it!
