kc Posted March 23 Share Posted March 23 Well there are proper kit makers for that size engine and top of the list would be DB Sport & Scale with a good selection of scale models all of which are well proven. The 58 inch Tiger Moth is a favourite with many. Also check out Bill Kits who make foam wing kits - easier and quicker to build. Not too far away in Herts. either. Kits will be found to be a better buy as they supply the fittings and special bits unlike kit cutters Building from plans involves interpreting the plans and this is often the difficult part of the build. Also changing from electric to i.c. requires a certain amount of experience and thought to change or strengthen the front end for glow and arrange the tank access. Those Vega, Stampe, Argus and Comper Swift plans are all purpose designed for electric and would need significant changes to become glow models. Also changing from 2 stroke to 4 stroke might need experience - carb might be in different place and throttle linkage tricky. So choosing the right plan is important.

Thanks. I want something that will give me a bit of a challenge but nothing where a lot of building experience is required. Best way to learn I think. I'm chuffed with how the Coyote is going so it won't be long before I'm onto the next model. Quote Link to comment Share on other sites More sharing options...
kc Posted March 23 Share Posted March 23 I came across a review of BillKits Tomahawk yesterday in an old FSM July2000 which reminded me of their kits. I think their Pawnee would be an easier model to build though and if the website price is correct ( £97 ) and not out of date it's a good buy. They are at Royston Herts.

kc Posted March 23 Share Posted March 23 I see that you have bought an OS 40FP. All the 'experts' will tell you to use a 10 by 6 prop on a .40 but I found that an 11 by 7 was far better on my OS40FP. If you look back at the reviews from that time by Brian Winch you will see that the 40FP does nearly as many revs on the 11 by 7 as on a 10 by 6. Frankly it does not rev as well as some .40's but it turns a big prop well. So use an 11 by 7 and note that electric props are not suitable / safe for glow motors.

I like the Pawnee and the Piper, I think either of those will be the one for the 45s 4 stroke. 25 minutes ago, kc said: I see that you have bought an OS 40FP.

I wasn't aware of the props being different so that's good to know 👍🏻 Quote Link to comment Share on other sites More sharing options...
kc Posted March 23 Share Posted March 23 Engine instructions come with a list of suitable props. You choose a prop to suit the job - noise reduction is often a most important point as high revs give unacceptable noise and where you fly makes a difference. Sometimes you need all the power you can get. Some people like playing with different makes & sizes of props to get the ultimate power. Ground clearance is another point to consider -check whether an 11x 7 will clear the ground easily on your model. The review of the BillKits Tomahawk suggests changing the elevator bellcrank linkage system. It's high tailplane like the Coyote. Thats why I said the Pawnee would be easier - more conventional.

Hoochykins Posted March 23 Author Share Posted March 23 Dont suppose you have a copy of the review? I'll happily make changes is need be. In just working out the best method to make the Coyote canopy magnetic. If anyone has done this before on similar to the Coyote I'm all ears. These ones. I also don't like the look of the wooden horns you get in the kit and waa going to change to the plastic screw ones, this won't cause any issues I'm not aware of will they?

kc Posted March 24 Share Posted March 24 (edited) Do a search on the forum for Coyote and you will find canopy hatch has been covered already- about 11 years ago! Much other info on Coyote and the similar Ridge Runt too. You may find comments on horns there too. Plastic should be OK but it depends whether the balsa is very soft and could be crushed. Thin cyano can be used to harden balsa or the ply horns. Some people cut horns etc themselves from Paxolin or printed circuit board. Also a search for Bill Kits found this thread with photos of the Pawnee kit from last year. Note the comment on wheels if you are buying. I don't think you need such big magnets for a small canopy - magnets about 5 or 6mm dia are very powerful and cheaper too. Magnets that are too strong could need too much force to undo and damage the canopy etc. Edited March 24 by kc Quote Link to comment Share on other sites More sharing options...
