RE: Juno RC F-20
I'm planning on powering mine with a TT-46 Pro with Tower muffler or an SK 50, I'm not sure which retracts to go with though, this will be my first plane with them.

RE: Juno RC F-20
admittedly I would prefer pneumatic retracts.. but this sort of keeps the cost down a bit..one modification that i am planning on is to blend the air ducts into a type of wing fillet , dont know what it will look like but hopefully might gain a slight speed advantage from this idea..hence the retracts are a must ... I could be wrong here but I think Cyclic has used the hobbico retracts and it sounds like he's happy with them so why not at $19.99..good value since most mechanicals are around $50.00AUD or more...just got to get my diamond dust finished just got to sheet it now and make the engine/pipe enclosure..then it's the F20.

RE: Juno RC F-20
yeah you get the three ,the two main gear and the one nose gear..this is the first time I will be using hobbico..I probably would have gone with better retracts ..but the budget has been soaked up ...
FM- well if thats your aim I'm sure the 60LX is the engine to do that
man I wish I could get a 60LX...sounds like a damn fine engine!!!

RE: Juno RC F-20
I got the F-20 yesterday, I can't wait to build it, should I sheet the wing completely or leave it with the open bays?

RE: Juno RC F-20
Another question, when using retracts, the center line of the tank will be higher than the carb, will the use of a pump be nessasary for proper operation?

RE: Juno RC F-20
I havent unrolled my plans yet , but these things usually arent to much of a problem and if the tank is high it's usually not to high..but again I have to check my plans on this...then again if it allows in the plans to make the nose gear a bit longer so the slight lean back slows the flow at idle but under pressure everything is fine!

RE: Juno RC F-20
I suggest building the wing upside down. Although the instructions state otherwise, I prefer building it upside down. That way the top spar is flat against the building board. Make sure the wing building shim is installed correctly. I noticed when I was building mine that is made more sense to build the wind inverted, and install the shim as stated in the instructions. I had to think about it a bit, take measurements, and visualize it before I was satisfied. The current instructions are the originals, left over from DC. I'm not sure what the intent was, but it seems the shim would have to be installed just the opposite as written if using their building method. I built mine inverted and it all made sense to me.................I hope this helps.

I looked at my plans and it says to use a pumped engine if using retracts.

I dont know about that. There are a couple guys here using YS45 (pump) but that was just choice. Most others are on a Jett 50 or some OS thing with no pump and no problems------all with retracts.
