92.5" Piper L-4 Grasshopper
I got chance to buy a new ARF 92.5" Grasshopper from the second hand and I had DLE 20 without any employment, so I bought it. There is only one problem. I bought it without the tubes in the wings. They are with diameters 19 mm ( 3/4") and 11 mm (2/5"). It is almost impossible to buy some tube with this diameter in my country, but I believe, I´ll solve this small problem.
I very like the look and performance of this HK ARFs, and the scale balloon wheels look very good. I hope it will be good on a grass airfield.

This ARF kit could be the first for someone who wants to build the first ARF airplane. There are prepared mounts for servos and every hole is named. The elevetor could be controlled by one or two servos. And very similar situation with the throttle servo. You can put the prepared mount on the right or left side of the fuselage- it depends on side of throttle bar on the engine.
After my experience with CMP and ESM kits I decided to brace a gear mounting. I pasted four hard wood bars between the gear mount and formers.

There wasn´t some good fixing of the fuel tank. Manual says it goes through the two formers and behind the tank should be only deck in the cockpit. So I decided to make new mount.
I had to use some PET bottle. Original fuel tank with volume 500 ml is bigger but 250 ml is enough for me.

I would like to add some weapons to my Grasshopper. I found out some pictures with six bazookas under the wing. There was mounting a trio of bazookas under the each half of the wing.
I try to find some better picture, does anybody know about some better shots? Other thing which I don´t know is the diameter of each bazooka.

Nice work Prekin! I've got a new 25% Bill Hempel L-4 ready to fly now. The AGM30 I bought for it won't run though. Bummer! !
Your bazooka idea is cool. May try that myself so be sure to post pictures of how you do them.
Got my Zero flying finally. Already had to replace the canopy though. The Top Flite 50cc canopy fits perfectly.

Yes Casey, I´m busy, but I need some sloooowly airplane for my dad, and I think, that Piper is good choice. Both of us love warbirds, so Grasshopper is could be a good compromise. Thank you for the information about the diameter.
In my opinion Top Flite canopy should fits the 50cc CMP Zero. If you want I can measure lenght and width of my CMP canopy. Top Flite Zero is a little bit bigger but the difference is smaller than 5% so it is insignificant. What pics would you like?

Here you can see the CMPro locks on the side doors. In lower part of door are two lock with springs. In the upper part are two holes for magnetic iron. It is smart solution, because in the lower part of right wiing are also two magnetic irons. So when you open the door you don´t have to hold it.
I wanted to paint the black stripes but I don´t have black paint. So maybe tomorrow, or after maiden flight. I hope it will be this weekend.

Last day I completed tail and glued new tail wheel. I had to bought a new one, because the one which was in ARF looks like a toy- not suitable for so big model.
I was suprised when I put the landing gear on the scales. Weight of this landing gear is 400 g (0,882 pounds).

I would like to add them after maiden flight. I´m in a hurry with completation of my Grasshopper, because I have last three days when I´m at home. So maybe I´ll fly it with out the cowl and cords on the rudder and elevator.

Casey, Yes, it looks to be an exact fit. I haven't removed the broken one completely yet but just laying it on top everything matches including the frame spacing. Paint is different but who cares! Pictures in the next few days.

Some progress for today. I found some olive green paint and I painted tail wheel and all horns. At the morning I comleted main gear and lock all nuts and screws. Now I hope all landings and rollings would be without any prbolem. I don´t want to repeat the story as with my ESM Dauntless.
