Anyone have a new or nearly new OS 20 FP they's like to get rid of, sell?

I'll be putting it in a Flight Streak ARF as a trainer for our new flying circle.

That will be a spritely one, for sure. Currell

Hey Dave: Don't rule out a 25 FP. I assume you are going to be running this in high rpm mode anyway. Just put a smaller venturi on it. You will be throttling it back, getting better fuel draw, but, essentially, the same power, the same weight, same run.

I have an OS 20FP on my streak ARF is is as fast as the Fox 35's. I have 3 additional OS 20's, in excellent condition, and can certainly accomodate you if you still want one. Dennis

David,

What's wrong with your Veco 19 and the trick cooling arrangements?

Still, you are on the right track. My ARF Flite Streak with a 25FP (modded RSM tongue muffler) is grossly over-powered for what I want from the FS.

Incidentally, I went to the length of spending approximately 50% of the price of the ARF on a couple fuel tanks, what with nearly instantly rejecting the stock unit. While the GRW 3.25-ounce chicken hopper tank works quite well, much better than the inboard-mounted Tettra tank, I find myself short-filling the tank nearly always. Yep, to about 2 ounces, or approximately the capacity of stock tank.

Look, I have never claimed to be very smart when it comes to equipment pressed into service in pursuit of CL Flying Fun.

Ya I discovered at Brodaks that a 25 FP with an air filter and muffler will run well over 10 minutes on 3 ounces of fuel

Dan,

Thanks for the advice on the tank, I'll take a look at it. The planes are backordered till Aug sometime though.

To answer you question, the Veco is worn out, however I have several new ones, but this is probably going into the ground a lot. I don't want to damage any of the new Vecos by ripping a very nice Big Art muffler off the side of the exhaust.

Dennis, yes please, I would like to buy one. From what I've seen, the 20 has a more stable run than the 25, and both have more than enough power. Please contact me through direct E-mail, I'm in the Pampa directory and on the web site list. Thanks very much. Dave
