bigedmustafa,
Thank you very much and your advice was much more appreciated, but I got your message long before I ordered my engine. It all started from knox hobbies website as I saw it it says free shipping but there is some *** asterisks/ star signs there and you are charged shipping. I sent an e-mail to the guy and told him it's a rip off, I guess he took it serious and I sent that guy Dewayne Solomon an apology e-mail, then I ordered my engine, 8 days I didn't hear anything from him I sent him several emails, then he came up with an excuse of family illness, then he came up with another excuse that USPS lost my package, as I sent him a gruffy email as I never got any info from him, no tracking # nothing like that person was evaporated in the air, no news of him, no info, no way I could get hold of him, no phone nothing. He replied back to me that I don't take threats, I told him threatening is not my strategy, I wanted to make my point clear regarding raising a disput at paypal. He told me your money would be refunded completely and I sent you an engine so better send it back to me as soon as you get it. I did not get my engine so far, infact he never sent it to me, as he got even with me for saying them rip off. Infact I have not gotten anything from him. He did write a best wishing mail of my job as I mentioned it to him last week as I lost it last week.
Well, I bought my Magnum from tower hobbies and expected to be here on Wednesday. I gotta break in and I'm expecting my Hitec Supreme 8 Channel Rx which I bought it ebay brand new for $35 with shipping. It's info is not there, and I hope it would be shipped tomorrow to me and I bought the Xtal for 72.810 channel 51 as well. My Escapade would be finished and I would have the engine break-in, then of course maiden flight

I would use 10X6 prop for break-in and prolly run 4 tanks on it. I'm using 10% Nitro and I'd continue to use it.
Sorry I did not mean to steal the thread

But I know good times are coming ahead for us financiallyl and economically.
Happy Flying.
