Start with a prop that has a more mass, like an APC prop. Also opt for a lower pitch ( so you can leave the engine at a slightly higher idle ) at first until it is run in.
Once you've run a gallon through the engine swap out the props and return. You should then get a nice idle around 1800 RPM.
i already have over propped it... im running a vess 15x6 on a 91... i have it on a 8ft Telemaster... its a really nice combo..
i might go in on the low end...but that probably wont be for a while, i really dont fly it unless i have someone to train
your problem is most likely because you engine is not fully broken in. magnums take about 3-4 gallons to breakin but once that is done they will run with the $300 saito and os engines.
my magnum .52 took about 3 gallons for the idle to drop from 2500-3000 down to 1800 but now it runs like a top, patience is the key.
