I just replaced the engine in a nice Dave Patrick Conquest IV and need to check the Cg before I take it out to try. "Nose heavy fly crummy, tail heavy fly once!"

Anyone have a clue?

Thanks

As I remember from the 2 Conquest IVs that I owned you should make them really tail heavy in relation to plan cg position. They fly much better this way.

I don't have the plans! Do you have any idea/reference points?

Thanks for your reply!

I will try to find the plans and will be back.

Well, the plans shows the cg at 50 percent of the root chord (19cm of 38cm). Otherwise it shows it at 35% of MAC which you can find at 47cm from the wing tip. I have to repeat that the plane flies much better with an aft cg position with absolutely no tendency to tip stall.

Here's a "famous" Stavros we have in Aus. No insult intended to RCSTAVROS or Greece but bear in mind this add is played without subtitles in a vastly non-Greek speaking country.

I got my Conquest from a poor guy whose wife was divorcing him and "getting rid" of his stuff by putting it on the lawn. I bought it from him as a mercy killing. It came with a rear exhaust OS .61 pumper RS fire breather which had the very annoying habit of 'going-rich'. It would run like ganbusters for 3 minutes , then it would start slowing from over rich. In fact I had an unanticipated landing and had to repair it. The engine swung a 13X9 which is very very big for a 61. I replaced it with a Wbra Speed 61 which I hope will provide enough power. BUT...the Webra was 2 ounces lighter...I will rebalance according to your directions.

Is that Australia or Austria ?

I think you can get a kit for the Conquest VI or VII from Jim Graham at R/C City ( glass and foam ).
