You mentioned 16000 RPM taken from the manufacturer's website. Cox fuel has a very high percentage of Nitromethane. Which fuel will you be using?

maahinberi

No sir, the parts are not laser cut. I just used a simple paper cutter  ;)

I shall initially be using just methanol with 20% oil, then if need be I will increase the nitro content. Though, yes, the manufacturer's website quotes performance figures for 25% nitro

Verynice workmanship.
Pl consider tissue and dope for wings. Old fashioned but saves weight.
Best of luck.

Already bought Monokote. Shall be starting with covering tomorrow.

1. Monokote. Wing loading 12.5 oz/sqft
2. Oracover. Wing loading 10 oz/sqft
3. 6oz/sqft

For a Cox .049 without nitro, you should be in 6-8 oz/sqft range

Look at the quality of the joints.
Hard to believe it's a beginner with a paper cutter.
Either laser or an experienced old style builder.
How many newcomers have a Cox now?
Sir, reveal yourself!

maahinberi

Thank you, and will keep that in mind for my next build. Just hoping that my oversized engine would be able to take the weight. :/

Hahaha, no really, I have only assembled two 46 size ARFs and done one scratch build before. The scratch built plane was for the same engine and it crashed on its third flight only. The CG was too aft and as it was free flight, I was able to do nothing to save it. Watched it stall and dive head first into the ground at full throttle.  :(

As for the Cox, I was always interested in planes so my dad got me a controls line plane from the US when I was around 8 years old. The plane got damaged in transit while we were shifting our house and thus never flew even once. I wasn't able to do anything with the Cox as I didn't have the fuel and didn't know where to get it from. It's only recently when I got introduced to aeromodelling that the fuel and equipment became available to me. The engine had been run before and had been lying in a drawer for 9 years. I just sanded the electrical contacts and filled the tank with fuel and attempted to turn it over, not at all hoping that bit would start but it spluttered and half an hour later, I was able to run it for a full tank. Then I decided to build a plane for it.

I shall be using the following control horns:

I don't have the screws for these.
Can I stick them with epoxy, or do I need screws?

Covering the Horizontal stabilizer. Covering is a little loose. Am I tacking the covering at too high a temperature? Or do I need a higher temperature to shrink it?

Covering the Bottom of the wing. Covering is still puckered. Any tips?
