Default Global Jet Club F-86F

Received it yesterday and unpacked today. It's a nice sport scale F-86 that is nicely done. I plan on a RCU build sequence on this thread. For now here is the beginning.

First step us to fuel proof interior. I removed the tray, intake and tank and used rustoleum by brush.

Looking at the configuration of that tank it seems it might be wise to have a second vent on the other side.

I think another vent would just cause a nasty leak in certain attitudes, flying or handling, unless you tee them together. The vents would certainly need to be teed together if you want to use a taxi tank........I don't think a second vent is needed. fuel being drawn out will draw air in.

I may be missing something here, but don’t see the logic in a second vent and would leave it as is.

I may be missing something there, but I don’t see the need for a second vent (or even the logic of the suggestion) and would leave things as they are.

OK. Of course the vents would be "T"d together. Look at that tank again and consider this....when fueling and the level reaches the concave portion of the tank, the side with the vent will continue to fill while the side without a vent will not. Unless of course you want to live with having to tilt the plane fairly steeply and shake it like crazy to get fuel in there every time you refuel. BVM F-86 tanks are similar in shape and have vents on both sides. Those guys knew a few things.

Anyway, it's up to Tom to decide if he needs it or not.

Unless the tank is partitioned it will fill properly. It would of course need a second vent if it were to be partitioned. Looks like a fun scale bird to enjoy all the time!!

I give up. You guys win. You all know better. The air trapped on the side without a vent is going to just magically go away all by itself. Yep. I get it now. Stupid me. I don't know what I was thinking.

Good point Steve. I was just considering venting when running. Maybe it was a matter of simplicity and taking a small fuel penalty.

This is my initial idea for electronic stuff.. The CB220 will power the CB100 which acts as an expander. I need 18 servo ports. The gear and doors will be sequenced by my DS16. If you haven't tried an AR Q-Switch you should. I can control the power to the radios, gear, brakes and lights through the R3RSW in the Q Switch. I tried it on my GJC F15 and it works great. As for the vent or not to vent, I will use a 2nd vent if I have a spare laying around, if not the fuel loss is minimal for my Cheeta.

Now for the business end. I hear the jet is nose heavy so I will put my Power Pack and UAT on the fuse sides. I need to leave the fuel tank sides clear to be able to remove the tank when necessary. If I have to, I can build a plate for the top of the tank for the PP and UAT.

Well I guess i was thinking about smaller Sabre I had plumbed same way. I simply picked one wingtip up to facilitate air removal. Maybe in this bigger one that might be a pain!

Got my motor mounts from my main source, Aeropanda. Initial fitting looks good. Will put a ply nut plate under mounts for a blind nut/bolt


motor mount.

Q-Switch mounted. Servos will be here Monday and will jump on them. Decided to wait for the UAT & Power Pack mounting until I get it on the balancer to help with the CG. 3 3300 LiPos coming. 2 for radio and one will power lights, gear and brakes.

Wow, people in this thread don't instantly acknowledge your expertise on a model you don't own and you're just going to take your ball, pout and go home? If you really want to give up on the thread just stop posting instead of the histrionics....jeez

Got the motor mount finished today and motor and pipe mounted. Spent the rest of the day updating firmware on TX, RXs (the new Rex7 A40 with dipole antennas), CB220, CB100 and Cortex Pro. Made leads for Rx 1 & Rx 2 and short leads for CB/Cortex link using PowerBox heavy duty wire. Tomorrow I will finish a connector for nose gear light and by then my servos should be here. Lots of progress expected this week.

Default F86 balance

This will not be nose heavy. I have 2x2600 mah receiver packs 2x2400 mah and a 3 cell 2500 mah LiFe ECU pack in the nose, plus all of my radio and turbine equipment on the front plate, the turbine pushed all the forward and a full UAT and it will still require 1 and 1/2 pounds in the nose to balance.
