Well, our field is grass and has a geotech style tarp runway. So don't see much issue for the maiden whenever that occurs. What I really like is the lightness of the wheels.

What club are you flying in?
I'm interested in finding out more about geotech.
Thanks Eric

Re: Semi scale Mig-25 Foxbat, 70 mm

Latest modification, the main access hatch. Even though it was a fairly good size, realized I could not have access to the steering servo and getting the battery in was a bit of a pain, so, made the hatch 5" longer, huge difference. Full access to the interior.

Just epoxied the two hatch sections together, waiting for the drywall compound to dry. Quick sanding and I'll apply new 3/4 oz cloth and you will never see the modification.

Re: Semi scale Mig-25 Foxbat, 70 mm

Just did a weight check, yikes, 86.5 oz, did not like that number, the EDF makes 1100 watts of power, might have a real problem. I could loose some weight by eliminating the retracts, but I really wanted landing gear. Also, I could eliminate the separate receiver battery which is only a 1000 mah item so very little weight.

I think I'll simply spray paint it with latex to keep the weight down too.

Re: Semi scale Mig-25 Foxbat, 70 mm

That's 200 watts/lb. John- don't know about the wing loading but it should certainly fly. Of course more power would be better! My FlyFly Sabre flew fine for years at around 7.5 lbs. and 1200 watts.

Re: Semi scale Mig-25 Foxbat, 70 mm

Off to Home Depot to get the paint. Guess it will be the grey paint job, the camo will take too long and I'm getting tired of working on this project. So, before I loose interest, the grey is the easiest to do, also, the least expensive.

After looking at the photos, I see there are a lot of fairings and other detail that can be easily replicated, so I'll be doing some vaccuforming with lightweight styrene. I think it is the details that really bring the models to life. These will be done after the maiden flight of course.
