Looks great, now FLY IT!! :yesss:

Spent a little time in the shop last night cutting up the bodies for the TMaxx and Revo to try and get more air flowing to the engines.

View attachment 104066

The Revo had a small hole in the front, but the TMaxx had no holes to let air through, so I opened up holes front and rear, and the sides too. Trying to get as much air flowing through to keep them cool, because restarting an engine after it overheats isn't fun :oblong: I would like to get the carbs reset after a tuning nightmare in the desert this weekend, looks like I richened both the low ends WAY up. Appears that may be more difficult with a horse now residing on the property :rolleyes:
Just trying to help, do Not know how much you have played with gas cars. But I have spent about 20 years racing 1/8 gas cars. Cars are tuned very differently than planes. Cars with short tune pipes need to tuned as rich as possible and while you running down the straightaway it must have a continuous steam of solid blue smoke coming out of the exhaust. When at idle you need to keep touching the throttle to keep it running. If your car was not set up like this you would never finish a 3 hour race. Just make sure when cutting holes in the body to make sure you keep the dirt of the engine and gears.

Does look good @Snoopy1 . But I have to ask.....Is there a reason for not sheeting it ?
Yes to many complex curves and did not want to spend or do that much work on a plane that is not high on my list. It flys good but it is simple 82inch wingspan aeroplane. It is just a fast sport plane with 4 stroke glow engine on it.

Ah ha. I see. Just 82". You and @stangflyer are obviously from the same DNA. :big_yes: ???:laughing:

Most of my planes are 50 to 60 cc one 100cc and one 150cc plane. But I must say my favourite at this time is 60cc size easy to work on easy carry through the house and I can man handle it by my self and fits nicely in the mini van.

Thanks for the advice, I've been on and off the past 15 years. My tuning advice comes from several individuals, one of whom has his name on a large number of race spec engines, none of them have told me to tune these engines as rich as possible. Generally I will richen the tune a couple of hours in the summer heat but otherwise I'll tune them to be as close to perfect as possible for the given conditions. These Traxxas engines seem to have some air leaks out of the box though so it's been a re-learning experience sealing them up and getting them tuned correctly.

All my experience is with Rossi engines never run the Traxxas engines. What I am trying to say is tune the top end to max rpm and then keep making richer until it four strokes and then lean it just until it goes back to full 2 stroke power. If we did not get this just right it would always lean out during a race and would loose the race or ruin a 500 to 600 dollar engine. Getting an engine race ready took anywhere up to 6 hours of tuning the gearing, pipe length, glow plug heat, Fuel mixture and oil content, so ruining an engine was painful.

I too have been enjoying the 50-70cc class planes the most for the same reasons for the past few years. I have however recently been enjoying the EPO electrics. Way easy to manage and they really have put the fun factor back in it for me. I can stuff all three (Cap, Extra and Avanti S) in the mini van and fly each twice for an average of 6-7 minutes. Great for these hot days where I can sneak out and have wheels up from 6-8 pm when the wind has died down and that scorching ball in the sky is not frying my brain. :oops: Well......used to stuff all 3 in the van lol.

Woohoo! look what showed up! Purdy Tettra 20 oz tank that fits like it was supposed to go there! Terrible picture, but you get the idea. Getting closer to getting the Focus in the air. Thanks Kelly (@49dimes ) for the tanks! They are just what the doctor ordered. Fits through the precut opening in the hatch too. Woohooo!

Good old pattern plane with a YS up front should be fun. Run the engine on 20/20 it will thank you and run for ever. But you will be able to run for ever on A 20 oz tank. Have fun with it.
