CHECK OUT PART 2 WITH TBOB PETE FLYING THIS TIME -
• SEAGULL MODELS YAK-3U ...
WELL THE PLANETS FINALLY ALIGNED AND WE MANAGED TO GET DEANO ON THE STICKS OF DADS LITTLE YAK RENO RACER,
AND WHAT A PLEASENT LITTLE WARBIRD SHE IS TO FLY,
PERFECTLY SUITED FOR THE DLE 20cc PETROL (OR ANY EQUIVALENT MOTOR)
NOT SURE OF HER WEIGHT AS WE HAVENT WEIGHED HER YET BUT THE BRAND NEW (STILL RUNNING IN) DLE 20cc MOTOR SURE DOES PULL HER AROUND WELL !
WE ARE USING A 30:1 OIL MIX (AS THE MANUAL STATES) AND A MASTER AIRSCREW 16X8 GLASS FILLED PROP !
THE MANUAL STATES THAT THE C OF G SHOULD BE 160mm FROM THE WINGS LEADING EDGE BUT WE FOUND HER TO BE VERY SENSITIVE AT THIS SETTING ,
IN THE END WE SETTLED FOR 150mm AND SHE SETTLED DOWN NICELY,
WE HAVE TWO 2100mah 2 CELL LIPOS ONBOARD (SEE THE PHOTOS) - ONE FOR THE IGNITION & ONE FOR THE RETRACTS / RECEIVER RUNNING THROUGH A POWERBOX SWITCH THAT REDUCES THE 7.2 VOLTS DOWN TO 5.9 VOLTS SO AS TO NOT DAMAGE THE RX & SERVOS & RETRACTS THAT ALL OPERATE ON 6 VOLTS !
THE NEW DLE IGNITION UNITS CAN RUN ON8 VOLTS SO A 2 CELL IS NOT AN ISSUE FOR IT,
SHES A PLEASURE TO LAND ON FULL FLAP (REMEMBER TO POWER HER IN GENTLY BLIPPING THE THROTTLE RATHER THAN GLIDING HER IN) AND THE SUPPLIED UNDERCARRIGE OLEOS HAVE STOOD UP TO THE LANDINGS SO FAR !
WE ALSO USED A SET OF EFLITE ELECTRIC RETRACT UNITS INSTEAD OF THE KIT SUPPLIED MECHANICAL UNITS SIMPLY FOR EASE OF SETTING UP ETC,
THE ONLY VICES WEVE FOUND IS THAT IF YOU PULL HER OFF TOO EARLY ON THE TAKE OFF RUN SHE WILL DROP HER LEFT WING (SLOWLY - DEPENDING ON HOW HARD YOU HAUL HER OFF) BUT IF YOU JUST LET HER BUILD UP SPEED SHE WILL LIFT OFF WHEN SHES READY !
THE OTHER VICE IS SHE WILL TIP STALL AT HIGH SPEED IF YOU ABUSE THE ELEVATOR ! SHE WILL TRY TO TUCK HER LEFT WING UNDER IF YOU TRY HAULING HER AROUND LIKE AN IDIOT, JUST FLY HER SMOOTH AND SENSIBLY (LIKE DEANO IN THE VIDEO - LOL) WITH SMOOTH FLYING AND BIG TURNS ETC,
WE DIDNT COME ACROSS ANY MAJOR ISSUES DURING THE BUILD PROCCESS JUST SOME MINOR ISSUES OF THE COVERING COMING UNSTUCK IN PLACES,
A NICE TOUCH IS THE COCKPIT KIT INC PILOT THAT SEAGULL HAVE SUPPLIED - SAVES YOU A LOT OF GRIEF AND TIME MAKING YOUR OWN COCKPIT !

The Yak-3 was one of the smallest and lightest Soviet fighters of WWII, and it was liked well by its pilots and ground crew. Some of it’s pilots even boasted that its capabilities were greater than the Mustang and Spitfire. Over several variations, the Yak-3 had different engines.
While this itself isn’t uncommon, it’s much rarer for a fighter to start life with a V-12 engine and then have a radial-engined option later on! The radial engine version, which is a Yak-3U, required many modifications to the airframe, but resulted in a much faster aircraft with a lower potential of overheating the engine.
The Seagull Models Yak-3 is modelled after William Whiteside’s iconic racing aircraft, which set an unofficial speed record, for aircraft under 3,000kg, at 416 mph (670 km/h) over a 3 km (1.863 mile) course back in October of 2011! Will’s Yak-3 looks quite spectacular,

thanks ricardo, we didnt use take off flaps as far as i remember, and landing flaps are set as much as you can get (like in the video)
18x8 on a 20cc? Or is that a typo?

sorry frank i never weighed her, if you do roughly as i have then she will have a good wing loading !
Hmm. Seems like quite a lot of engine for a Gangster 63. Mine went well enough with a Merco 61... (Just kidding!)
fly's nice on 20cc pete, remind dean that the throttle has more than one position!

Yak 3u was a radial version of yak. But it does look almost indentical to an la. I think the radial yak never saw action though.
