Yip - I raised the rudder control servo = you can use 1/4 inch stock....here in SA we use 6mm!!!

I secured the fuel tank with "velcro" straps and used some light/soft foam sheeting to wrap the tank before installing.

I must admit I prefer only using the clear fuel tubing because its easier to see the fuel = checking for bubbles...

I tried using the fuel pump from a certain supplier but after the third one in a year failed = the exchange rates for money makes imports horrific expensive here[:@] I changed to using a small header tank at the firewall and exhaust gas pressure to the main tank. Whish I had of tried that first and saved a whole heap of money for the fuel instead!!! It worked great[8D]

My Leo was powered with an OS91FX with self made aluminium side to rear header piper and standard OS tuned muffler arrangement. Ample power....until I recovered with glasscloth and resin and painted the plane
