Easystern- That is the sweet linkage there on the Maggy. I am a big fan of the $39.99 Hitec-645MG (107/ 133oz) servos.
hi razor rcu...
i had no clue what servo is fine for the magnum ,i caled allen at weston uk and he told me go by the 645 mg thats what i did.
its a fast and strong one , sometimes i get some storrys about metal gear should not good for high revving /vibrating planes, don't know..... i got the 645 on a rc fair 25% down in price
hi 72 nova....
how big is the cobra ,
i got the same engine for a little plane to, would be interesting what prop would be fine to get lots of rpmmmmmm's out of that engine.
we have a nice muffler company here in germany ,the make a perfect quiet stainless steel muffler with more rpm's then the stock muffler. they use the mufflers on 90 % in the reno racing class on stock engines and in planes 60' size planes.
stuckerjuegen is the company.
