OS 50SX piston

This is the piston from my OS 50SX which I purchased second hand (?). Bit of a carbon build up which I am removing. Note the small circle in the gap in the piston ring. This is where the piston ring meets and aligns with no ports on the liner. The front on the piston has the circular cut away.

Super Tigre G21/46 Stunt engine

Finally I have freed up this engine so that I can mount it in my Magnum. I may need to get a stunt venturi made to save a bit of weight. The piston and liner appear to have little use which is great.

GMS2000 120 Glow Motor

Well I just purchased one of these, what a big piece of metal. Arguably I got it a bit cheaper but then the muffler I suspect is for a .60 (and shoehorned on!!) but then the engine does not come with a muffler. The spinner looked good in the photo but the backplate is broken. Hopefully it will be ok running it like that.

Fournier RF4 model

To the right is my model Fournier RF4, around 80 inches in wingspan and powered by a OS 25FP. It flys well although it won't fly itself. Been sitting in the garage for 10 years but she now flys again. Engine was totally gummed up but after heat and some TLC, engine runs again fine. I didn't build it myself. When I remember the guys name I will give him credit.

Will Hobby AT-6 Texan - Wing servo pushrod

I have just connected up the wing servos to the ailerons. Straight forward except 1. The pushrods need to be cut to length and bent. 2. Don't forget the fuel tube "keepers" to stop the clevis disconnecting from the aileron horn.

Will Hobby AT-6 Harvard - The front end

I feel that the front end where the firewall is glued to the fuselage is not up to it for a long term model. I have added 1/2" balsa in front of the firewall (see picture) to give it more strength. Then I have fuel proofed it.

Assembling the Will Hobby AT-6 - Joining the wings

Almost time to join the wings together. Pictured is the wing joiner (one for each side). Its pretty sloppy in the slots in the wings so I am going to face it with 1/6" ply to get a better fit before I glue it together. Note that the inner side is longer than the outer side.
