Status: offline 		I recently purchased a 1/3 scale Sopwith Pup in the bones. It is a fresh build straight out of the box. No dust or discoloration of the wood. Would like to here from others who have built or own one of these beauties. Color schemes, servos, pilots, interior, tricks and things to look out for in finishing the model. I have a GT-80, which will pull it nicely. I have been looking on the Internet for a DGA 1/3 Scale Full Body Pilot Kit without any success. Several sites claim to have some of them left however after talking to them none are around. I know that DGA is gone. Does anyone have an extra one or know someone who does and is willing to part with it?

Thanks for the information. The pilots at Proctor appear to be to small even at 1/3 scale. The AH pilot also seems small. The DGA pilots measure 23 1/2" tall which would be about 5' 9" tall in real life.

Thanks Again
Fred

Status: offline 		here is what i found with mine,
1. dont use the supplied clevises for the flying wires, they will come loose in flight during aerobatics use dubro # 302 instead
2. silver solder the flying wire fittings-not silver bearing solder, and not your normal acid core solder
3. change the flying wire fittings at the cockpit (upper wing rear wire attachment at the fuse) as designed they are attached at the ply sides, and will pull out, either add a bracket inside to the fuse former or run a support clear across the fuse to the other side
4. mine started at 31 lbs rtf was tough on windy days, once i increased it to 37 lbs rtf it totally changed the windy day effects, i have flown in 25 mph winds with gusts to 35. tail up landings work best keep speed up and chop throttle when on the ground. blip throttle if it trys to nose over. i will now even do cross wind take offs and landings. get used to using that rudder ALOT, this plane LOVES rudder, much more effective then ailerons.
hope this helps

Status: offline 		Thank you for the additional info. I will review these issues. I have someone who is going to finish the building of the plane. I just do not have the time currently and I do not want it to sit around unfinished. I will address these issue with him. As luck would have it there are a couple of these planes flying in the area which I can also view. Neither of these owners built their planes however they do have some experience on how they fly and are rigged.

I will keep everyone informed.

Status: offline 		Don't try to roll it , will scare you to death . Trouble is i think , that the fact it has 3/8 wood dowels to locate the wings & there is so much slop that the wings can move , I had a 1/4 sopwith pup & have a 1/4 scale sopwith triplane & both roll good , but differance is that the 1/4 pup had 2 wings in one piece , not joined , the Triplne is in sections but has s/head cap screws to bolt together . On scale builder web one time i asked if anybody had ever rolled this kit model , 2 replied & said "yes but never again " . Just try tapping the wing tips when it is assembled & see the movement . But if you fly around , do a loop , stall turn , its a wonderful model .

Status: offline 		Fellas,
Several years ago I flew a Balsa USA 1/3 scale Pup. It was built pretty much like the plans called for with a few scale touches added here and there. The flight characteristcs were fantastic! It looped, rolled (both snap roll and axial roll), stall turned, wingovers......pretty much the same manuvers that the full scale plane could do with a few more that the early pilots hadn't even thought about.
The difference between the smaller models and the 1/3 scale Pup is that the third scale Pup must be flown through the manuvers, in particular, the rudder must be used a lot! I was even able to do a rolling circle with mine. Don't be afraid of it......just take it up really high and give yourself a chance to learn the flight characteristics. Just remember, if you fall out of a manuver, back out of the throttle and slowly regain level flight. Just thinking about that old bird makes me want to get another one up and flying again!

Status: offline 		Hello fellow Pup pilots; Just came upon this thread. Been building Pups since 74 ,from .40 to 1.2 in one scale or another and now finishing a BUSA 1/3 scale that I started 14 yrs. ago but always had something interfere with finishing it. I do want to suggest that this plane was a scout/fighter, not an aerobatic plane. A snap roll? Never. Axial roll? Not on your life. But a long ,graceful, rudder roll is a thing of beauty. A well executed chandelle with the Pup hanging on a stall at the top could befuddle any plane chasing it.Please fly this plane like the real one. A 850 lb. machine powered by a mere 80 HP rotary. Remember your visuals ! I'm OK now , just had to get that out!! puplover

As an example a WWII Fighter had an average roll rate of 3.5 seconds.. WWI planes were about twice that or greater. These planes are much more convincing when flown prototypical.. IMHO.

Thanks for the information. I spent the morning building my Balsa USA wheels for the pup. They came out better than I thought they would. Yesterday I received my cockpit and machine gun kits form Arizona Models. I have not opened the cockpit kit yet however it looks good in the pictures. I have seen the machine gun kit and look forward to building it. Has anyone built one of these cockpit kits and or a machine gun kit? Any advice and or pictures would be appreciated.

Thanks again.
