Hi everyone,

First post, I've finished my T-28 a couple weeks ago. Made a few small changes that I copied from your posts, I'm using a Saito FA80 I bought from a guy in our club new in the box for $90.00, a good deal but it's weight is giving me a ton of grief.
It must be very light for this plane as it flew very tail heavy. To get it to fly level with no trims it took 6 oz of lead on the back of the motor mount. All you guys are saying yours balance fine. Is the saito that much lighter then the Magnum or OS 91?
I even put the battery under the fuel tank..

Any Ideas

Thanks
Carl
Hello Carl,

Welcome to the T-28 club I checked with the Saito site and the 80 weighs 540 grams which converts to 19.048 oz. while the Magnum 91 2 stroke weighs 24.8 ounces. So I am guessing that this is the reason for your plane being tail heavy and having to put 6 oz of lead on the firewall. Hope this helps you out. Tower Hobbies has a conversion program on their website to help you convert grams to oz and so on.
